Large Bets and Stock Market Crashes

A QWAFAFEW discussion arranged by Mark Kritzman and led by:

Anna Obizhaeva

Co-authored with Pete Kyle


For five stock market crashes, we compare price declines with predictions from market microstructure invariance. Predicted price declines half as large as the 1987 crash and almost equal to the 2008 sales of Societe Generale suggest that useful early warning systems are feasible. Larger-than-predicted temporary price declines during two flash crashes suggest rapid selling exacerbates transitory price impact. Smaller-than-predicted price declines for the 1929 crash suggest slower selling stabilized prices and less integration made markets more resilient. Quantities sold in the three largest crashes suggest fatter tails or larger variance than the log-normal distribution estimated from portfolio transitions data.
