Abstract The anomalies literature in capital markets research in finance and accounting is based (almost) exclusively on average realized returns. In contrast, we construct accounting-based expected returns for dollar-neutral long-short trading strategies formed on a wide array of anomaly variables, including book to market, size, composite issuance, net stock issues, abnormal investment, asset growth, investment to assets, accruals, earnings surprises, failure probability, return on assets, and short-term prior returns. Our findings are striking. Except for the value and the size premiums, the cost of equity estimates differ drastically from the average realized returns.
