摘要:
We examine whether the cross-section of equity option returns can be predicted with a collection of well-known stock return predictors. The answer is yes for the majority of these variables, including idiosyncratic volatility, size, past stock returns, profitability, cash holding, new issuance, and the dispersion of analyst forecast. Such predictabilities are not mechanically inherited from the stock market because stock return predictability is weak to non-existent for the underlying stocks in our sample and our results hold for delta-hedged option returns. We document new option trading strategies that are profitable even after transaction costs. These profits are robust across different market conditions and subsamples. They cannot be explained by standard stock market risk factors, volatility risk or tail risk. Our results have important implications for option valuation and option market efficiency.
