An asset’s sensitivity to stock market volatility carries a signi…cant risk premium across both equity and …xed income markets. Large-cap and growth stocks have less exposure to volatility risk. Their relatively greater ability to weather volatility surprises, such as those often associated with …nancial crises, accounts for their lower expected returns when compared to small-cap and value stoc...

A method for computing forward-looking market risk premium is developed in this paper. We first derive a theoretical expression that links forward-looking risk premium to investors’ risk aversion and forward-looking volatility, skewness and kurtosis of cumulative return. In addition, investors’ risk aversion is theoretically linked to volatility spread, defined as the gap between the risk-neutr...

We study the daily trading volume volatility of 17,197 stocks in the US stock markets during the period 1989-2008 and analyze the time return intervals τ between volume volatilities above a given threshold q. For different thresholds q, the probability density function P(q)(τ) scales with mean interval 〈τ〉 as P(q)(τ)=〈τ〉(-1)f(τ/〈τ〉), and the tails of the scaling function can be well approximate...

We construct investor sentiment of UK stock market using the procedure of principal component analysis. Using sentiment-augmented EGARCH component model, we analyse the impacts of sentiment on market excess return, the permanent component of market volatility and the transitory component of market volatility. Bullish sentiment leads to higher market excess return while bearish sentiment leads t...

This article uses Bayesian marginal likelihood analysis to compare univariate models of the stock return behavior and test for structural breaks in the equity premium. The analysis favors a model that relates the equity premium to Markov-switching changes in the level of market volatility and accommodates volatility feedback. For this model, there is evidence of a one-time structural break in t...
