CORRELATED BEHAVIOR IN LIMIT ORDER CANCELLATIONS,COMOVEMENT IN ASSET RETURNS,AND COMMONALITY IN LIQUIDITY

We examine whether there is common behavior in limit order cancellation activity, that is, commonality in cancellation activity, on U.S. exchanges. We then examine whether this commonality in cancellation activity is associated with increased levels of return comovement and commonality in liquidity. We document strong evidence of limit order traders exhibiting exchange, industry, marketwide, and stock-level commonality with regard to cancellation activity, which is consistent with limit order traders exhibiting correlated trading behavior. We also find that this correlated behavior in cancellation activity is associated with increased levels of return comovement and commonality in liquidity.     

Quote Stuffing

In this study we examine intense episodic spikes in quoting activity (frequently referred to as quote stuffing) on market conditions. We find that quote stuffing is pervasive and that over 74% of US exchange‐listed securities experienced at least one episode during 2010. We also find that stocks experience decreased liquidity, higher trading costs, and increased short‐term volatility during periods of intense quoting activity. We find that most quote‐stuffing events occur on the NYSE, ARCA, NASDAQ, and BATS and that during these quote‐stuffing events, the number of new orders and canceled orders increases substantially while the order size and order duration decrease.     

What Effect Did AIG's Bailout,and the Preceding Events,Have on Its Competitors?

We examine the effect of American International Group's (AIG) bailout, and the events leading up to it, on its insurance industry rivals. The reaction of rivals to AIG‐related events depends on the relative strength of two competing effects. The contagion effect implies that rival returns will decrease following negative events affecting AIG. In contrast, competitive effects will occur if investors expect that rivals will be able to benefit from AIG's downfall. Using three‐factor multivariate regression model event study methodology, we find evidence of both effects around several key dates in AIG's decline.     

Towards Some Principles for Intangible Asset Accounting

This paper examines the conceptual issues of intangible asset accounting in the context of recent controversies over the treatment of brand names and goodwill in company accounts. Issues of definition and recognition and the rationale for balance sheet disclosure are considered for goodwill and other intangibles. The implications of capitalising intangibles under accounting models based on present value, net realisable value, current cost and historical cost are examined, and certain principles are proposed. The problem of testing the validity of asset valuation is explored, and a test is developed on the basis of the ‘recoverable amount’ rule of historical cost. This test is demonstrated for two major UK companies.     

The Declining Role of NASDAQ Market Makers

We compare the liquidity providing behavior of NASDAQ market makers in 2010 to their behavior in 2004. We examine how frequently market makers are at the inside quote, what market and stock specific factors influence market makers’ behavior, and the relation between market maker participation and intraday bid‐ask spread patterns. We observe a decrease in the percent of the trading day dealers’ quote at the inside, a decline in the number of market makers, and a decrease in the influence market makers have on intraday spread patterns. The results suggest that the role of NASDAQ market makers declines over time.
