While theoretical models strongly suggest that short-sales are mainly driven by private information, recent empirical evidence of has been rather mixed. This paper contributes to the discussion by looking at various potential motives to sell short and compares these with regular buys and sales...

We examine the differences between short sales and "regular" trades with regard to the nature of their information content. First, we find that short-sales impound private information that is significantly longer-lived than that in regular trades, and accordingly find that short-sales play an...

We investigate and test hypotheses on how informed trading varies with market-wide factors and the structural and trading characteristics of a firm. We find strong evidence of commonality in informed trading, and a systematic dependence of informed trading on firm characteristics that is largely...

Regulatory and media concern has focused heavily on the potentially manipulative distortion of market prices associated with naked short selling. However, naked shorting can also have beneficial effects for liquidity and pricing efficiency. We empirically investigate the impact of naked...

We investigate the nature and extent of information asymmetry among traders in companies with government ownership. Consistent with a less transparent information environment, we find relatively less informed trading in the shares of firms with government presence, and specifically, fewer...

We empirically examine on-exchange hidden liquidity in the context of informed trading, pricing efficiency, and trading costs. Using a number of proxies for informativeness and a number of different specifications, we find that when an on-exchange option to hide orders exists, traders prefer to...

We investigate the aggregate market quality impact of equity shares that fail to deliver (hereafter “FTDs”). For a sample of 1,492 NYSE stocks over a 42-month period from 2005 to 2008, greater FTDs lead to higher liquidity and pricing efficiency, and their impact is similar to our estimate...
