An accounting analysis of the risk-return relationship in bull and bear markets

This study provides evidence that accounting beta (earnings and cash flow-based) provides information consistent with the risk-return relationship in up- and down-markets. We are not able, however, to provide similar evidence using market beta. Considering that investors' ability to assess the risk-return trade-off in up- and down-markets is central to efficient portfolio formation, the results suggest that accounting data can provide appropriate measures of portfolio upside and downside risk.
