With market risk and credit risk, you could lose a fortune. With liquidity risk, you could lose the bank!

LVaR = position ($) * [-drift (%) + volatility *deviate + LC]; 0.5*spread " No single measure captures the various aspects of liquidity in financial markets."

3 Copyright, Yogesh Malhotra, PhD, Current State of Liquidity Risk Measures Assets: Specific Assets: General Coherent Measures Popular Liquidity Models (Price, Quantity, Time) Bid-Ask Spread Exogenous Position Size Endogenous Resiliency (Rare) Trading Volume (Flawed) - Flash Crash Aggregates of Multiple Basic Liquidity Measures Long-Short Index Measure Chacko, Das, Fan (2012) Long the ETFs Short components of ETFs Liquidity as Shadow Asset: Kinlaw et al. (2012) - Identify optimal weights by maximizing expected utility - Substitute illiquid asset for liquid equity - Solve for illiquid asset return based on σ and ρ - Estimate AR(1) Model using least squares - De-smooth the time series Liquidity as Real Option: Ang & Bollen (2008) Investors decision to withdraw capital: real option Lockups & Notice periods: exercise restrictions: reduction in the value of liquidity option. Bangia et al. (2001)Berkowitz (2000) Giot & Gramming (2005)Stange and Kaserer (2008) Tightness, Depth, Resilience (Kyle, 1985) Aggregates of Multiple Basic Liquidity Measures Bid Ask, Volume, Turnover, Loeb Price Impact (Lo 2010) (Amount of Trading, Cost) Serial Correlation as proxy. Liquidity Adjusted CAPM (Acharya & Pedersen, 2005 JFE) Risky and has Commonality Constant Trading Frictions Volume Weighted Spreads 1. Bid Ask Spread, 2.Transactions (Volume), 3.Volume Weighted Spreads Comparing individual assets liquidities is problematic because one asset could be more liquid along one dimension of transaction costs while the other is more liquid in a different dimension. "No bank can ever afford to hold enough liquidity during normal times to be able to survive a severe or prolonged funding disruption." Basel Committee Jarrow & Protter (2005)

4 Copyright, Yogesh Malhotra, PhD, Autocorrelation Measure of Relative Liquidity & Setup for a Wall Street Asset Management Firm Assets: Specific Assets: General Portfolio Scale for Relative Liquidity How fast price (t) decays - Faster decay, more liquid How long stale price (t) lasts - More it affects, less liquid - Longer it lasts, less liquid Y Proxy for Liquidity Risk Plot serial correlations Use Model to find Decay Measure Decay Factor "Liquidity risk today is where credit risk was 10 years ago." " In times of financial crisis, asset prices in some markets may reflect the amount of liquidity available in the market rather than the future earning power of the asset."

The future isnt the past." " People have known since Mandelbrot in 1963 that returns are not normally distributed."

Yet in real-world systems, nothing could be less normal than normality. Tails should not be unexpected, for they are the rule. "
