The Impact of the Boxing Day Tsunami on the World Capital Markets
Abstract
The effects of the Boxing Day Tsunami on the world equity markets are investigated in
this paper. In particular, this paper studies how the risks and returns of industry and
market portfolios are altered as a result of the tsunami. The analysis includes
countries that were directly and/or indirectly exposed by this catastrophe. Both
parametric and non-parametric tests are employed to explore the relationship
between equity stock returns and the tsunami, and the CAPM is utilised to assess the
variation in systematic risks. Given that the literature in this area is underdeveloped,
we draw on the economic theories of flooding. In that sense, our results are consistent
with the flooding literature, whereby it is predicted that the Boxing Day Tsunami has
minimal impact on the risk and return of equity markets. This paper documents few
abnormal return changes and a general increase in the long term systematic risk of
equity portfolios in the study.

I. Introduction
According to Roll (1988), stock markets around the world react differently to major
events. Furthermore, Rietz (1988) and Barro (2006) postulate that rare and extreme
events change risk premia in financial markets. On the 26th of December 2004, an
earthquake measuring around 9.3 on the Richter scale occurred under sea in the
Indian Ocean, triggering what is commonly referred to in the literature as the Boxing
Day Tsunami. This event resulted in the loss of lives, missing and displaced people,
property damage and psychological scars in the countries that were directly hit. Whilst
the humanitarian data has been documented, little is known regarding how the stock
markets in those countries reacted to this incident. Further, the literature in the area of
how international markets are affected by this incident is also sparse. As such, the
objective of this paper is to test the hypotheses of Roll (1988), Rietz (1988) and Barro
(2006) regarding whether a major event, such as the Boxing Day Tsunami, affects the
volatility and return of capital markets around the world.
In the political economic literature, Keys, Masterman-Smith and Cottle (2006) argue
that the tsunami impaired the life of poor people-regions and countries that do not
have the power to drive the market in the first place. Such argument is upheld by
subsequent regional studies. For instance, Bandara and Naranpanawa (2007)
3
uncovers significant firm losses due to damages of assets and infrastructure in some
geographical regions of Sri Lanka. Bird et al. (2007) discusses the impact of
socio-economic disturbances on local communities within the tourism industry in
Langkawi and Malaysia. Other researchers refuse to limit the consequences to
geographical regions and attempt to extend that literature to the macroeconomic
level. Ichinosawa (2006) led by showing that the tourism industry was affected in
Thailand; Lee, Wu and Wang (2007) demonstrates that the FOREX markets of certain
countries were affected and this study adds to the debate. Specifically, we contribute
to the financial literature by exploring how the tsunami influences risks and returns in
the equity markets. Interestingly, literature on the impact of the tsunamis does not
exist and so we rely on the natural disasters literature. A study carried out by
Worthington and Valadkhani (2004) shows that bushfires, cyclones and earthquakes
tend to change market returns, whilst severe storms and floods do not.
There is another growing literature on the effect of disasters on GDP, wages, labour
markets and they show that disasters in general have important and sizable effects
[see Kahn (2005), Raschky (2008), Strömberg (2007) and Toya and Skidmore
(2007)]. In a similar vein, there is a developing literature on the impact of
environmental news on the stock market [see Dasgupta et al. (2006); Dasgupta et al.
4
(2001) and; Laplante and Lanoie (1994)]. Therefore the main objective of this paper is
to bridge the gap in the literature on the effects of tsunamis on capital markets.
The countries that were directly struck by the tsunami provide an ideal testing ground
for the above arguments. According to the UNDP, there were 12 countries that were
affected: Indonesia, Sri Lanka, India, Thailand, Malaysia, Tanzania, Bangladesh,
Kenya, Maldives, Somalia, Myanmar and the Seychelles. The likelihood of another
tsunami with the same magnitude is relatively small, but due to climate change, a
similar flooding incident may occur as the result of an increase in the sea level. It is
thus important to know what the consequences of such a calamity are for these
countries in the event that history repeats itself. As a result, we study all of the market
segments within these countries (conditional on data availability and the existence of
a stock market). We then extend our analysis to the rest of the world to determine
whether there are any externalities or spillover effects. In total, we study 41 countries
that were not directly hit by the tsunami.
We hypothesize the following. First, if investors perceive an increase in their expected
costs or a decrease in their revenue after the tsunami, they will respond negatively to
such that event. For instance, the tourism industry will be adversely affected in the
5
countries that were directly hit as tourists will move to alternative tourist destinations
that were not affected by the incident. Secondly, if investors perceive a decrease in
their expected costs or an increase in their revenue, then they will react positively to
the tsunami. It is not unusual to find booming businesses during these catastrophic
events, for instance there will be an increase in demand for cleaning, maintenance,
health care and telecommunication companies around that time of the tsunami.
Finally, investors may not react at all if they do not foresee any change in their cost
and revenue analysis. One of the reasons to believe that the tsunami will not move
share prices is that this event does not contain any information effect for
company-industry in question. Systemic risk, conversely, will either increase or
remain unchanged by the amount of the tsunami risk if the cost and revenue structure
is altered. As it is not clear as to which of these possible outcomes will prevail, this
paper investigates these relationships.
The contributions of this research are as follows. First, a detailed industry analysis is
carried out, and this identifies precisely which sectors within a country that was
directly hit by the tsunami are affected. Secondly, to the best of our knowledge, there
is no current study on the aftermath of the tsunami on the world’s capital markets.
Hence, the objective of this paper is to bridge the gap between the tsunami and equity
6
markets around the world. This study will be of interest to market participants who
trade internationally, more specifically in emerging markets, as it documents how
these markets reacted to the tsunami. In the event of another similar incident,
investors can use the results of this report as guidance for making their investment
decisions. This analysis will be beneficial to portfolio managers who use the top-down
investment process, as it also provides the industry effects of tsunamis. Third, this
paper is meant to be historical and unique in nature, given that tsunamis of this
magnitude are extremely rare. Additionally, the last tsunami in the Pacific region
occurred on the 30th of September 2009, killing over 140 civilians in Samoa and this
incident is an indication that a tsunami can occur at anytime and that this threat
cannot be ignored.
The findings of this paper provide some support for the hypotheses of Roll (1988),
Rietz (1988) and Barro (2006) in that we find that the Boxing Day Tsunami has the
potential to increase the long run systematic risk of equity portfolios. There were,
nonetheless, minimal statistical changes in abnormal returns for most of the portfolios
studied. This leads us to give more consideration to the conclusions of Keys,
Masterman-Smith and Cottle (2006) and Worthington and Valadkhani (2004) in terms
of the insensitivity of financial markets to the tsunami. Section II presents the data and
7
methods used in this paper. Section III presents the empirical findings, and Section IV
provides some concluding remarks.
II. Data and Methods
Data
Table 1 briefly summarises the consequences of the tsunami on the 12 countries that
were directly affected. We state whether they are regarded as tourist destinations, the
number of recorded fatalities and the number of missing/displaced persons as a direct
result of the calamity. Out of these 12 nations, only eight has a registered stock
exchange, and we manage to get the equity data for seven of these countries,
namely, Indonesia, Sri Lanka, India, Thailand, Malaysia, Bangladesh and Kenya. We
downloaded daily stock return indexes and risk-free rates for the period January 1999
to March 2007 for these seven countries from Datastream. The sample deliberately
excluded 2008 and 2009 in an effort to isolate the impact of the subprime crisis. Using
the Global Industry Classification Standards (GICS), we organise 3,097 firms in the
sample into 11 industry-based portfolios. One practical issue we faced in the process
is the small number of firms populating some industry sectors. To overcome this
issue, we modify the GICS standard and created a sector called Other. Table 2
provides a breakdown of these industrial portfolios according to country of domicile.

The impact of the tsunami on other capital markets is also studied in this paper. These
countries were not directly hit by the tsunami, and in total, we downloaded 41 equity
market indices from Datastream. Countries such as Iran, Nigeria, Pakistan and
Saudi Arabia were excluded, as there were no relevant stock market data for these
countries. Furthermore, we were unable to obtain the relevant risk-free rate data for
Botswana, Bangladesh, Bahrain, Egypt, Iceland, Jamaica, Jordan, Latvia,
Luxembourg and Zimbabwe. In order to control for the international differences, we
converted return data into US dollars, and the MSCI world index is used as a proxy for
the world market return.
Methodology
Return Analysis
Worthington and Valadkhani (2004) studied the impact of natural events using a long
term time series analysis. In an effort to differentiate our work from their study, the
event study methodology of Brown and Warner (1985) is used in this empirical
analysis to determine whether the returns of the industrial and market portfolios are
impacted by the tsunami. First, the daily returns on individual stocks are calculated
using the natural log of the price relative. The ex-post abnormal returns (ARit) for each
9
firm are then calculated as the difference between the observed returns of firm i at
event day t and the expected return- whereby the daily expected return is estimated
using the CAPM, in excess return forms over the last 260 observed daily returns. Next,
the abnormal return for each industry I, ARIt at time t is obtained by averaging the
abnormal return of each firm within the industry.

The market portfolio for each country is estimated in a similar manner. On the first
trading day after the tsunami, the industry abnormal return calculated using Equation
1 will predominantly respond to two factors: firm-specific information and the actual
tsunami event. In an effort to capture only the impact of the tsunami and to be free
from other firm-specific information, all firms with firm-specific information 15 days
before and after the event day are excluded from the industry portfolio. However, not
all of the countries sampled has readily accessible information on the existence of
relevant announcements. Thailand, Malaysia, Sri Lanka, and India were found to
have data available on the release of firm-specific information, but we were not
successful in obtaining the necessary data for Indonesia, Bangladesh1, Kenya, and
Tanzania. Firm-specific information is defined as any announcement made on the

data, it was not possible to use in our study. The poor quality is predominantly because of the old
technology used to store such data.
10
domestic stock exchange and around the December period a large number of
companies released their end of financial year reports. If we do not isolate the effects
of these firm specific information, then our results will have two components namely
earnings announcements and tsunami effects. In an effort to capture the sole effects
of the tsunami, we exclude the firms with firm specific information. It should be noted
that for the market index of the countries that were not affected by the tsunami, we do
not exclude any firm-specific information.
The parametric t-statistic for the industry abnormal return is estimated as abnormal
return for each industry divided by their corresponding standard deviations. One of the
underlying assumptions of this parametric test is that abnormal returns are normally
distributed. Nevertheless, the literature dealing with abnormal returns show that they
are not normally distributed. In particular, the distribution of abnormal returns tends to
exhibit fat tails and positive skewness. In event studies such as this one, the abnormal
returns can be potentially large on the first trading of trading right after the tsunami.
Consequently, the following two biases may occur. We are more likely to reject the
null hypothesis for positive abnormal performance and are less likely to reject the
hypothesis of negative abnormal returns. As a result, we turn to an alternative test
developed by Corrado (1989), which is a non-parametric ranked t-test. It should be
11
noted that Corrado and Truong (2008) argue in favour of this non-parametric test in
event studies around the Asia-Pacific financial markets. The basic principle of this
method is to convert the abnormal returns into a sequential rank. As ranks are
generally not very distant from each other, the ranked distribution is less prone to
non-normality. However, we use this test as a robustness test because it can only
indicate the direction of change of the returns and cannot provide a magnitude of
change. Given that this non-parametric test does not use the actual values, some
academics do not regard this test as a strong quantitative technique. As a result, we
will favour the parametric test results over the non-parametric ones, when we have
conflicting results. Finally, the periodic abnormal returns are aggregated for the
individual industries over five days to obtain the cumulative abnormal returns (CAR).
This represents the excess return investors receive over the five day period and
measures the ability of the equity market to rebound or deteriorate further five trading
days after the tsunami.
Risk Analysis
According to the efficient market hypothesis, investors assess all risks before making
their financial decisions. Trading investors who perceive the tsunami as a risk will
result in a general increase in market risk. We therefore test whether the tsunami
12
has an impact on the systemic risk of the industry and market portfolios. We use the
standard CAPM model and apply the Chow breakpoint test to see whether systematic
risk changes following the tsunami. The shortcoming of this approach, however, is
that it only reveals a structural change in the model and will not identify the element
that changes. Under the CAPM, it is possible to observe either a change in the
intercept or a change in the slope (market risk). Nonetheless, the Chow test does not
differentiate between these two factors and reports the results in aggregate. Further,
the CAPM does not differentiate between long-run and short-run changes in the risk
level. To that end, we fit the CAPM with dummy variables to capture the short term
and long term changes in systematic risk that may be generated by the tsunami.
Equation 2 below is used to test whether the tsunami has an impact on the systemic
risk of each industry on the first day of trading following the calamity.
itftmtIftmtIIftIt STErrrrrr ~*]~~[]~~[~~ 21 , (2)
where Itr~ is the industry i’s portfolio return at time t, ftr~ is the risk-free rate at time
t, and mtr~ is the return on the market at time t. STE stands for short-term effect and is
a multiplicative dummy variable that takes the value of 1 on the first day of trading
following the event and 0 otherwise. This variable is meant to capture the short-term
effect of the tsunami on systematic risk. it~ ,
1
I , and 2
I are the error term, the
13
beta and the coefficient on the dummy variable, respectively. i is the intercept of
the regression equation with E( i ) = 0 expected.
To test for a change in the intercept, an additive dummy variable is required. The
inclusion of an additive dummy variable in Equation 2 results in a near-singular
variance-covariance matrix. This is because the additive dummy variable and the
multiplicative dummy variable are highly correlated. Consequently, we estimate a
separate equation to test whether the intercept was affected by the event:
itIftmtIIftIt STErrrr ~]~~[~~ 21 . (3)
Equation 3 is estimated for completeness, as the value of the intercept is expected to
be zero. Equations 2 and 3 thus capture the short-term effects of the tsunami on the
systemic risk of equity markets. The long-term effects of the calamity on the
systematic risk of firms are calculated using Equation 4 below:
itIftmtIftmtIIit LTELTErrrrr ~*]~~[]~~[~ 321 . (4)
The test determines whether the level of risk is altered after the event day. The
long-term effect (LTE) is captured by a structural dummy variable that takes a value of
0 prior to the event and a value of 1 after the day of the event (until the end of our
sample). This variable captures structural changes and the influence of the tsunami
on systemic risk over a long-term horizon.
14
The above risk models are adjusted for exchange rate changes as we convert all the
returns into US dollar equivalent, and the MSCI world index is used to generate the
international capital asset pricing model (ICAPM) for the market portfolios. Standard
tests and residual diagnostics for normality, autocorrelation, heteroscedasticity and
ARCH effects are conducted for all of the regression models. Most of the regression
models displayed standard non-normality, autocorrelation and ARCH effects. Given
the large sample size, we are not worried about non-normality issue and appropriate
AR terms are added to the model to address the problem of autocorrelation. A
GARCH(1,1) model was added to solve for ARCH effects. We also test whether the
dummy variables are redundant in the above equations using a Wald test.
III. Empirical Findings
This section outlines the empirical findings of the effects of the Boxing Day Tsunami
on the industrial portfolios of the countries that were directly hit and the market
portfolios of 41 countries that were not directly affected by the disaster. Using
parametric tests, a non-parametric test and regression analysis, we test whether the
risk and return of industries and markets were affected by this rare incident. Using
different testing techniques, we observe that the tsunami has a very minimal effect on
15
the abnormal returns of the equity portfolios that were studied and results in an
increase in systematic risk for certain sectors.
Return Analysis
The market in Bangladesh opened one day after the Boxing Day Tsunami. It is thus
important to note that we are assessing the performance of the Bangladeshi portfolios
on the 27th of December 2004 and that this is consistent with the event study
methodology. This implies that on that day, the market participants had at least one
night to think about their strategy in the Bangladeshi equity markets. Further, it is
important to remember that firms with firm-specific information surrounding the event
are not excluded from the results reported in Tables 3(A), 4(A) and 6. This implies that
the results contain both the tsunami and information effects. Tables 3(A) and 4(A)
summarise the parametric empirical results for the different sectors in seven countries
that were directly struck by the Tsunami. The abnormal return on the first day of
trading after the event and the five-day cumulative abnormal return, as well as their
respective t-statistics for 11 different industries for these seven nations, are reported
in these two tables. Table 6, on the other hand, reports the parametric and
non-parametric results for the market portfolios of 41 countries. The results reported
16
in Tables 3(A), 4(A) and 6 show minimal evidence of statistically significant change in
the returns of the equities markets around the world.
Columns 6 and 7 of Table 3(A) report the abnormal returns and the parametric
t-statistics for the various sectors in Bangladesh. Table 3(A) shows that the returns in
the information technology (IT) sector in Bangladesh increased by 5.27% after the
tsunami, and the t-statistic shows that this value is statistically different from zero.
However, this positive change in return is more likely to have occurred because of the
IT outsourcing launch in Bangladesh at the time rather than the Tsunami.
Surprisingly, no other portfolio exhibits a statistically significant change in abnormal
returns. In other words, the remaining 59 industrial portfolios in the seven countries
were not affected by this event on the first day of trading. Columns 2 and 3 of Table 6
show that Croatia (-3.64%) and Ecuador (-7.55%) responded negatively, whilst Israel
(1.69%) responded positively. These do not appear to be any direct link between the
tsunami and the share market movements. For instance, the Crobex fell because one
of the 12 blue chip stocks in that index, Privedna Banka Zagreb-the second largest
commercial bank in Croatia reported losses. The Ecuadorean stocks index closed
lower in lackluster trading during a holiday-shortened work week whilst the Tel-Aviv
17
Stock Exchange (TASE) recorded few positive announcements on the day. In
addition, the remaining 38 nations showed little reaction to the tsunami. We can thus
conclude that the tsunami has weak statistical impact on the returns of capital markets
on the first day of trading. These findings are consistent the results of Keys,
Masterman-Smith and Cottle (2006) and Worthington and Valadkhani (2004), who
reported that tsunamis and flooding-related incidents show little equity market impact.
Other empirical studies focusing on the tsunami reports regional effects in sectors like
tourism and infrastructure; unfortunately, our results are not directly comparable, as
we study industrial portfolios for entire nations.
The efficient market hypothesis (EMH) posits that the market instantly reflects all
available information; perhaps the reaction in these markets was more leisurely. We
therefore assess how the market reacted five days after the tsunami, which enables
us to test whether there was a delay in the share market reaction (i.e., market
stickiness) to this event. The five-day cumulative abnormal returns support the finding
of insensitivity of the equity markets to the tsunami attack. Of the 77 equity portfolios
that are studied, only three portfolios exhibited a significant change in the cumulative
abnormal return over the following five days. The fourth column of Table 4 (A) shows
that the financial sector reacted positively (10.12%) and that the remaining sectors
18
showed no statistically significant change in CAR over the next five days in Thailand.
On the 27th of December the Finance Minister Somkid Jatusripitak ordered a
sweeping overhaul of Thailand's bond trading system- a move that would allow an
Asia Bond issue. These measures were expected to inject more liquidity to the local
bond market, with traders better equipped to deal with the variety of risk management
tools available. There were two other industries that were affected in Bangladesh:
energy and materials.
Thus far, the results that we have discussed lead one to believe that the tsunami do
not influence capital markets. However, we must be careful in interpreting these
results because they are contaminated with firm-specific information. After excluding
firm-specific information from our industrial portfolios, a new set of results was
generated, and we report these findings in Tables 3(B), 4(B) and 6. Out of the seven
countries that were directly affected, we only report the results for four countries.
There are two main reasons for this reduction in our sample; namely, either
firm-specific announcements are not available from that country or the country has its
financial reporting around this time. In countries where the financial year is in
December, we exclude the majority of the companies from our portfolios as they
publish their financial reports around the time of our event date. This second issue
19
leads to another serious estimation problem ranging from very small portfolios to no
portfolio at all. Table 3(B) shows that only the consumer discretionary sector in Sri
Lanka and the telecommunications industry in India were affected by the tsunami. The
telecommunication sector in India increased by 5.88%; this could be explained by the
fact that individuals used their phones to call the directly affected areas to find out
about the state of their relatives. However, this industry rebounded five days later, as
the CAR reported in Table 4(B) is not statistically significant. Interestingly, we do not
observe the same effects on the telecommunication industry in the other countries
and this discrepancy is hard to explain. The consumer discretionary sector, on the
other hand, was down by 3.61% in Sri Lanka. This industry consists of the
manufacturer of transportation vehicles such as cars, trucks, aeroplanes and travel-
and leisure-related activities. After adjusting for the firm-specific information, the
consumer discretionary sector consisted primarily of the transportation
manufacturers. It is likely that this industry faced a decline in returns, as the travel and
leisure industry was negatively affected around this time. Five days later, the
performance level of this industry dropped by 8.40%; this is shown in Table 4(B).
Another industry that was affected five days after the tsunami was Malaysia’s energy
sector. We found no statistical change in the abnormal return on the first day of
trading, or in the cumulative abnormal return. Even after excluding firm-specific
20
information, we cannot conclude that the tsunami has a significant effect on the
majority of the equity markets.
To control for the issue of non-normality in the distribution of AR, a robustness test in
the form of a non-parametric ranking based test is used. Generally speaking, the
results of the non-parametric tests support the results observed in the parametric
analysis. Considering the non-parametric2results in Table 5, it appears that this test
supports the view of the insensitivity of the equity markets with respect to the tsunami,
as most of the results of the non-parametric t-tests were not significant. However,
the non-parametric results for Sri Lanka cannot be ignored. The test supports the
finding that the consumer discretionary sector was down on the first day of trading, but
it also shows that a number of other industries were down around that time. Given that
the results of the non-parametric test for these portfolios conflict with the parametric
results, we favour the parametric test results as it is a more powerful test.
Risk Analysis
2 Generally speaking, when the reported non-parametric t-statistics are less (greater) than negative two
(positive two), we conclude that the abnormal returns were negative (positive) on the day of the event.
Note that this test only provides the direction of change; it does not inform us about the magnitude of
change.
21
Based on the above discussion, we can conclude that only the telecommunications
industry in India and the consumer discretionary sector in Sri Lanka were affected on
the day following the Boxing Day Tsunami. With the exception of these two portfolios,
the impact of the tsunami can be viewed as minimal and we can thus hypothesise that
investors did not perceive an increase in risk following the Boxing Day Tsunami. Our
next objective is to test whether the industrial and market portfolios were affected by
the Boxing Day Tsunami in terms of a change in their systematic risk. The
multiplicative regression analysis (see Equation 2) tests this hypothesis immediately
after the attack. Table 7 reports the results of the multiplicative dummy variable model
(Equation 2). A positive (negative) coefficient of the multiplicative dummy variable
(Coef. 3) reflects an increase (decrease) in systematic risk immediately after the event
and thus measures the short-term changes in systematic risk. The sign of the
coefficient (Coef. 3) appears to be mostly positive, and it requires the coefficient of the
multiplicative dummy variable to be statistically different from zero, to imply a
significant statistical change in the systematic risk of the industry. In Table 7,
t-statistics for the short-term changes in the systematic risk show no statistically
significant changes in any of the sectors studied in these countries. In other words,
there is no evidence to support the null hypothesis. The Boxing Day Tsunami altered
the market risk in the short term for any of the sectors in the countries that were
22
directly affected. Similar findings (data not shown) were observed in the market
portfolios of the other countries that were not directly affected by this tsunami. Our
results are not directly comparable to the current thin literature in this area. However,
we do observe similarities with Keys, Masterman-Smith and Cottle (2006) and
Worthington and Valadkhani (2004) in that tsunamis and flooding-related incidents
have a minimal impact.
Further, the additive dummy variable in Equation 3 shows the impact of the Boxing
Day Tsunami on the intercept of the CAPM. Once more, we found no statistically
significant change in the intercept, and as a result, we do not report these findings. It
should be noted that in this excess return CAPM, the intercept has no practical
meaning and is meant to be zero. In estimating Equations 2 and 3, we only show the
short-term impact of this tsunami; also, the Chow breakpoint test suggested changes
in the CAPM in certain sectors. As we do not observe any short-term effects, these
changes are more likely to be long term in nature. By applying Equation 4, we can
establish the direction of change in the long-term systematic risk. In particular, we test
whether the market risk changes in the long run. The results presented in Table 8
show that five industries in India, one industry in Sri Lanka and seven industries in
Malaysia exhibited an increase in systematic risk in the long run. For example, the
23
systematic risk of financials sector was 0.89 (see column 3 of Table 8) prior to the
event and increased by 0.15 (see column 4 of Table 8) after the calamity. The
systematic risk increased from 0.89 to 1.04 after the tsunami. The Wald test3 reveals
that for this industry (and for the consumer discretionary, consumer staples,
industrials and telecommunications sectors in India; the financial sector in Sri Lanka;
and the consumer discretionary, consumer staples, energy, health care, industrials, IT
and telecommunications sectors in Malaysia), the dummy variables were not
redundant variables, i.e., these sectors experienced an increase in the long-term
market risk. However, we do not observe any change in the long-term systematic risk
of the other 41 market portfolios.
IV. Conclusion
The literature on how tsunamis affect the risk and return of capital markets is almost
nonexistent. At best, we can draw conclusions on how tsunamis affect certain regions
and then speculate on how the international markets react to this sort of calamity.
Intuitively, one would expect a tsunami to have a negative impact on the financial
markets in terms of negative abnormal returns (i.e., a decrease in wealth) and an

24
increase in the risk of conducting businesses in the countries affected. However, the
evidence provided in this paper challenges this view. Using the Boxing Day Tsunami
as a tool, this study shows that equity markets, particularly the industrial portfolios of
countries that were directly hit and the market portfolios of other nations, were virtually
insensitive to this event despite the negative sentiment that prevailed following the
incident. The risks and returns of the majority of the industrial portfolios and market
portfolios did not change after this particular event. Surprisingly, only two industrial
portfolios experienced changes in their abnormal returns. Furthermore, we
documented a general increase in the long-term market risk of 13 industrial portfolios
in four countries that were directly hit. This paper finds theoretical consistency with
other related research suggesting that the Boxing Day Tsunami would have minimal
effects. We conclude that there was no major wealth destruction for equity investors
as a result of the Boxing Day Tsunami. These results reinforce the findings of Roll
(1988), Rietz (1988) and Barro (2006). We believe that the impacts are more of a
regional basis as shown by Bird et al. (2007) and Bandara and Naranpanawa (2007).
