We investigate whether short sellers are subject to the disposition effect using a novel dataset that allows to identify the weekly closing of short positions. Consistent with the disposition effect, the closing of short sale positions is strongly related to a proxy of Shortsale Capital Gains...

We investigate whether providers of high frequency news analytics affect the stock market. As identification, we exploit a unique experiment based on differences in news event classifications between different product releases of a major provider of news analytics. We document a causal effect of...

This Paper investigates the link between a firm’s competitive environment and the idiosyncratic volatility of its stock returns. We find that firms enjoying high market power, or established in concentrated industries, have lower idiosyncratic volatility. We posit that competition affects...

We study the relationship between inflation and stock returns focusing on the signalling content of inflation. Investors use inflation to learn about the stance of the monetary policy. Depending on investors’ beliefs, a change in consumption prices has different effects on the risk premium. A...

We study the relation between information and fire sales during a crisis. We argue that the reinforcing effect of funding liquidity on market liquidity is weaker when investors have more information about the assets facing sudden price drops (Brunnermeier and Pedersen, 2009). We focus on the...

We test the market impact of the disposition effect. We rely on the Grinblatt and Han (2002) model and derive testable implications about the expected relationship between the preponderance of disposition investors in the market and stock volatility, return and trading volume. We use a large...

We use a panel of more than 100,000 investor accounts in US stocks over the period 1991-95 to construct an investor-based measure of dispersion of opinion, unlike the analyst based measure used in the literature. We use this measure to test two competing hypotheses: the sidelined investors...

We study how debt market frictions constraining the ability to replace bank with bond financing during a tightening in bank credit supply affect corporate yield spreads. We document that more inflexible firms suffer bigger increases in bond yield spreads as bank credit supply tightens. Debt...

We study how actively managed equity mutual funds select the liquidity level of their equity portfolio and the effects of this selection on performance. We provide evidence of five key determinants of portfolio liquidity: portfolio size, portfolio concentration, the manager’s trading...

We study IPOs by focusing on the degree of portfolio diversification of the shareholders taking the company public. We argue that a less diversified shareholder has more to gain from taking the company public and would be more willing to accept a lower price for the sale of its shares, i.e....
