  24. Liquidity & the 1987 Crash Amihud (1990, JPM) • Stocks that experienced a greater increase in bid-ask spread suffer a greater price decline during the crash => liquidity is a price factor • Alpha2 is insignificant during the crash (II vs. I) but significantly negative afterwards (III vs. II) => flight to quality • By the end of 1987, spread had narrowed but remained higher than before Oct => persistence
