Business School and INSEAD


We use an 11-year panel of NYSE specialist inventory positions and 
revenues to study two aspects of financial markets: stock price 
reversals (temporary mispricings) and liquidity.  Understanding when 
stocks are mispriced and when liquidity is drying up is of key 
importance to asset managers.  We show that as stock prices go up, 
market-makers sell.  As stock prices fall, market-makers buy.  
Market-makers are compensated for taking on risky positions via stock 
price reversals.  Sorting stocks based on inventory positions predict 
reversals of 33 basis points over the following week and 45 basis points 
over the following two weeks.  Sorting stocks by current returns and 
inventory positions can predict reversals of over 85 basis points per 
week.  Combining inventory positions with NYSE specialist revenues 
allows us to predict liquidity (at the market-level) at a daily 
frequency.  As prices fall, market-makers lose money on current 
positions.  They also increase positions and thus risk.  The net result 
is that market-makers are less willing to provide liquidity.  Our tests 
are done at both the market-level and at the specialist firm level.  Our 
results suggest an important role for market makers' financial positions 
in explaining the time variation of liquidity.
