On the determinants of stock returns
Objective Present recent empirical evidence on the determinants of stock returns
Outline A review of determinants of stock returns Empirical evidence
Common sense determinants of stock returns Risk factors Liquidity factors Measures of cheapness Measures of profitability Technical factors Sector-related factors
Risk factors Market beta (trailing 60-montth) APT betas Volatility of total return (trailing 60-month) Residual variance (firm-specific risk over trailing 60-month) Debt-to-equity ratio NOI/Interest charges
Liquidity factors Market capitalization Market price per share Trading volume-to-market capitalization (trailing 12-month)
Measures of cheapness P/E ratios Market-to-book ratio Dividend yield OCF-to-price Sales-to-price
Measures of profitability Profit margin Total sales/total assets ROA ROE Earnings growth (trailing 5-year) Earnings surprise
Technical factors Excess return (relative to the S&P 500) in the previous 1 month Excess return (relative to the S&P 500) in the previous 2 months Excess return (relative to the S&P 500) in the previous 6 months Excess return (relative to the S&P 500) in the previous 12 months Excess return (relative to the S&P 500) in the previous 24 months Excess return (relative to the S&P 500) in the previous 60 months
Sector-related factors Durable goods Utilities Energy Constructions Manufacturing etc
Reality check: Empirical evidence Use stocks from the Russell 3000 Stock Index from 1979 to 1993 Run regression: R = a +b 1 Det 1 + b 2 Det 2 + ……+ e
Top ten stock return determinants in the decreasing order of statistical significance: Excess return (relative to the S&P 500) in the previous 1 month (-) Excess return (relative to the S&P 500) in the previous 12 months (+) Trading volume-to-market capitalization (trailing 12-month) (-) Excess return (relative to the S&P 500) in the previous 2 months (-) P/E ratios (-) ROE (+) Market-to-book ratio (-) Excess return (relative to the S&P 500) in the previous 6 months (+) Trading volume trend (-) OCF-to-price (+)
Interpretation Short-term reversal Medium-term momentum Long-term reversal Investors overestimate the mean-reversion period and/or growth rates (cheap stocks earn higher returns) Liquid stocks have lower expected returns
More questions What is the relationship between risk and return? Why do cheaper stocks have higher returns?
