Agenda for today

1. Correlation

Correlation is relevant for linearly-related normal variables, which are not so frequent in the real world

Correlation spikes when risk aversion is high

2. Liquidity

Overcoming the difficulties of estimating liquidity in equities: Liquidity at Risk

The challenge of managing illiquidity in Private Equity: cash flow modeling

3. Leverage

Hedge Funds: adjusting leverage to assets’ volatility

Private Equity: assessing the true impact of leverage

Murphy’s laws do not apply!

Standard commercial software and a good PC are enough to solve most of the quantitative issues.

Correlation is relevant for linearly-related normal variables …

Example of normal distribution: Banks vs. Diversified Financials

… which are not so frequent in the real world

Example of fat-tail distribution: Energy vs. Materials

Correlation is misleading in non-normal worldsNon-normal world … The real world … The HF world

Classical Risk Management tools break down! VaR does not work; Standard Deviation is misleadingPortfolio optimization is risk-measure dependentCorrelation based methods are insufficient

Murphy’s laws do apply!

No Universal Recipebut ad hoc approaches.

3. Leverage

Adjusting leverage to assets’ volatility

Two ways to the same risk profile:

High Market risk and low leverage

Low Market Risk and high leverage

Leverage: “A creation of exposure greater in magnitude than the initial cash amount posted to an investment.”1

Risk Amplifier

Thus leverage is strategy dependent

Examples of typical leverage:2 to 10 X for Arbitrage Strategies2 X for directional strategies such as Equity Hedge.

In Hedge Funds, leverage measure must be adapted to the strategy

The Leverage can be quantified in absolute terms or with respect to the risk profile of a reference index (effective beta equivalent).

Types of Leverage

Financial Leverage or Borrowing Leverage

Strategy Leverage : Impact of portfolio construction rules on the overall portfolio’s risk

Instrument Leverage (Gearing) : intrinsic internal leverage of financial instruments.

In Hedge Funds Leverage measure must be adapted to the strategy:

L/S Strategies: Gross Financial Leverage = (longs + shorts)/Capital

MKT Neutrals: Net Financial Leverage = (longs – shorts)/Capital

Arbitrage and Derivative Strategies: Leverage = Financial Leverage * Gearing

Adjusting leverage to assets’ volatility

Maximum Leverage

There is an optimal level of leverage to maximize the compound rate of growth over the long term, calculated according to what is known as the “Kelly Criterion* ”:

The rule can be used to scale the level of leverage to the strategy’s intrinsic volatility.

CAUTION :

Just considering volatility in Hedge Funds can be risky as FAT TAIL risk is magnified by the leverage.

Neglecting Leverage represents a suboptimal use of capital.
