– “CVS Caremark (CVS) issued weak 2011 earnings guidance, and its shares fell 6% in morning trading. CVS posted fourth quarter earnings of 80 cents, versus expectations for 81cents” Barron’s February 3, 2011

– Tyco (TYC) now expects earnings of 30 cents to 33 cents a share instead of the 45 cents to 47 cents guidance it gave in July, chief executive Ed Breen said in his first conference call with the company's investors.” AP September 2005.

Literature: Meetable/Beatable Forecasts (Mimicking)

Literature

• Skinner (1994) – Managers may preempt announcement of negative

earnings surprises to reduce the potential costs of shareholder suits

• Soffer et al. (2000) - short-term management earnings guidance tends to be downwardly biased

• Matsumoto (2002) and Richardson, Teoh, and Wysocki (2004) - firms “walk” analysts toward beatable earnings forecasts via their earnings guidance disclosures

Page 6: 1 Mimicking and Herding Behaviors among U.S. Investment Analysts: Implications for Market Reactions to Actual Earnings Announcements Liem Nguyen Westfield

6

Literature: Management Incentives

• Baik and Jiang (2006)– Management dampens analysts’ earnings expectations

with pessimistic quarterly guidance when their firms:– Have high growth opportunities,– operate in a high-litigation industry,– have transient institutional ownership.

– All factors above are associated with pessimistic management guidance because of the costs of missing the consensus of analysts forecasts.

Literature

Page 7: 1 Mimicking and Herding Behaviors among U.S. Investment Analysts: Implications for Market Reactions to Actual Earnings Announcements Liem Nguyen Westfield

Literature: Herding Behaviors

• Trueman (1994) - Math models predict that an analyst prefers to release an earnings forecast that is close to prior earnings expectations even when his/her own information justifies a more extreme forecast.

• Hong, Kubik, and Solomon (2000) - find that more experienced analysts are more likely to issue bold forecasts than are less experienced analysts and that brokerage firms are more likely to discharge the less experienced analysts for inaccurate or bold forecasts

Literature: Herding Behaviors

Literature

• Clement and Tse (2003, 2005)

- find that analyst characteristics are associated with forecast accuracy for both bold and herding forecasts

• Gleason and Lee (2003)

- bold forecast revisions generate stronger return responses than do herding forecast revisions

Literature: Herding Behaviors and Extreme Earnings Surprises Trueman (1994, p. 98)

When herding is observed among analysts:

Extreme surprise announcements of actual earnings => smaller stock price reactions than would be expected from analysts using information in an an unbiased manner to produce their forecasts.

Reasoning: Investors recognize the possibility that an analyst actually had information that justified a more extreme forecast.

Consequently, large earnings “surprises” do not surprise investors as much as if they had taken the announced forecast at face value.

Literature: Influence of Regulation FD

• Findlay and Mathew (2006)– After implementation in October 2000 of US. SEC

Regulation Fair Disclosure (Reg. FD), analyst forecast accuracy declines overall, but analysts that were less accurate (more accurate) before Reg. FD improve (become less accurate) after its implementation

• Bailey, Li, Mao, and Zhong (2003) – find that after the passage of Regulation FD, analyst

forecast dispersion increases

Research Motivation

How do analysts revise their estimates conditional on management earnings guidance releases?

How do following analysts revise their estimates when faster analysts revise their estimates following management earnings guidance?

Does Regulation Fair Disclosure change the way analysts revise their estimates?

Do analyst herding behaviors result in market reactions to actual earnings announcements as predicted by Trueman (1994)?

Data and Methodology

Data and Methodology

• First Call (1995 – 2009)– Annual earnings per share (EPS) management

guidance – Omit guidance events that occur after the fiscal year end

but before the earnings announcement– Mid-point of the earnings guidance if given as a range– Omit observations without CUSIP– Neutral/Negative/Positive Surprises: the guidance qualifies as

a positive (negative) surprise when it is higher (lower) than the current expectation based on the last analyst’s consensus update prior to the guidance

– Examine analysts forecast revisions issued within 7 days of management guidance

Hypotheses Related to Mimicking

Hypotheses

• H1-1: Analysts are less likely to mimic management’s earnings guidance for firms which ultimately experience losses than for other firms.

• H1-2: Analysts are less likely to mimic management’s earnings forecasts when following firms with higher potential litigation costs than for firms without this potential.

• H1-3: Analysts are less likely to mimic management’s earnings guidance for growth firms than for other firms.

• H1-4: Analysts are less likely to mimic management’s earnings guidance after the implementation of Regulation Fair Disclosure than they were before the implementation.

17

Hypotheses Related to Herding

Hypotheses

• H2-1: Following analysts are less likely to herd if the first analyst mimics management’s earnings guidance.

• H2-2, 3, and 4: Analysts are less likely to herd together for• -2 loss firms, -3 high litigation firms, -4 growth firms

• H2-5: Analysts are more likely to herd after the implementation of Regulation Fair Disclosure than before.

18

Hypothesis Related to Herding and Market Reaction to Earnings Announcements

H3: Under extreme surprise outcomes from actual earnings announcements, the overall market reaction is less intense if analysts previously herded their forecasts following the management earnings guidance than it is when herding was not observed among analysts in response to management earnings guidance.

Conclusion

• Analysts are less likely to mimic their estimates– higher litigation potential firms– growth firms– loss firms– After Regulation FD

• Analysts are less likely to herd their estimates– When the first analyst mimics– Before Regulation FD

• Confirmation of Trueman (1994) theory: Market reacts less intensively to actual earnings announcements of extreme (top and bottom 10%) surprises after observing analysts’ prior herding behavior.
