Betting against beta proxy · low 1-year volatility · top 50 · Top 500 · long only (after Frazzini & Pedersen 2014, AQR)
'Betting Against Beta' argues leverage-constrained investors bid up high-risk stocks, so low-risk stocks earn higher risk-adjusted returns. Approximation: 252-day volatility instead of beta, no leverage to equalise risk. Falsified if the low-risk portfolio's Sharpe ratio is not above the benchmark's.
