Are excess stock market returns predictable over time and, if so, at what horizons and with which economic indicators? Can stock return predictability be explained by changes in stock market volatility? How does the mean return per unit risk change over time? This chapter reviews what is known...

We study the effect of introducing a new security, such as a non-redundant derivative, on the volatility of stock-market returns. Our analysis uses a standard, continuous time, dynamic, general-equilibrium, full-information, frictionless, Lucas endowment economy where there are two classes of...

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...

The preferred risk habitat hypothesis, introduced here, is that individual investors select stocks with volatilities commensurate with their risk aversion; more risk-averse individuals pick lower-volatility stocks. The investors' portfolio perspective overlooks return correlations. The data,...

We investigate the relation between global foreign exchange (FX) volatility risk and the cross-section of excess returns arising from popular strategies that borrow in low interest rate currencies and invest in high-interest rate currencies, so-called 'carry trades'. We find that high interest...

Survey respondents strongly disagree about return risks and, increasingly, macroeconomic uncertainty. This may have contributed to higher asset prices through increased use of collateralisation, which allows risk-neutral investors to realise perceived gains from trade. Investors with lower risk...

This paper documents that at the individual stock level insiders sales peak many months before a large drop in the stock price, while insiders purchases peak only the month before a large jump. We provide a theoretical explanation for this phenomenon based on trading constraints and asymmetric...
