The Anatomy of Value and Growth Stock Returns

Abstract:     
We break average returns on value and growth portfolios into dividends and three sources of capital gain, (i) growth in book equity primarily due to earnings retention, (ii) convergence in price-to-book ratios (P/B) due to mean reversion in profitability and expected returns, and (iii) upward drift in P/B during 1927-2006. The capital gains of value stocks trace mostly to convergence: P/B rises as some value firms become more profitable and move to lower expected return groups. Growth in book equity is trivial to negative for value portfolios, but it is a large positive factor in the capital gains of growth stocks. For growth stocks, convergence is negative: P/B falls because growth stocks do not always remain highly profitable with low expected returns. Relative to convergence, drift is a minor factor in average returns.
