An Analysis of Changes in Specialist Inventories and Quotations

Abstract: We develop a dynamic model of market making incorporating inventory and information effects. The market maker is both a dealer and an investor, quoting prices that induce mean reversion in inventory toward targets determined by portfolio considerations. We test the model with inventory data from a New York Stock Exchange specialist. Specialist inventories exhibit slow mean reversion, with a half‐life of over 49 days, suggesting weak inventory effects. However, after controlling for shifts in desired inventorie… Show more

“…Consistent with the hypothesis 2, there is a significant negative relation between locals liquidity and position-taking profits across all contracts on the trading floor. This supports the conjecture made by Madhavan and Smidt (1993), that market makers are active traders when they possess information relating to impending order flow. Locals appear willing to sacrifice their liquidity profits in order to profit from favourable price movements.…”

“…Consistent with this, Madhavan and Smidt (1993) suggest that NYSE specialists profit in the short-term from information about impending order imbalances, attained through their central position on the trading floor. 4 If a local does not hold a position, then they will not be able to derive a return on their information.…”

“…We find that monthly returns, both in the cross-section and time-series, bear a stronger relation to lagged returns than to lagged order flow innovations. This indicates that inventory effects do not appear to completely account for the return reversal at the monthly horizon (though other authors, such as Madhavan and Smidt (1993) do find some evidence of inventory-related phenomena at daily horizons). We also find an interesting stylized fact: that order flow innovations at horizons of two to three months are negatively related to current returns in the cross-section even after controlling for lagged returns.…”
