Timing Value vs. Growth: Evidence from 100 Years of Small Value–Large Growth Spread

Core Insights - The article examines the long-term relationship between small value and large growth stocks over more than 100 years, suggesting that the spread between these portfolios can indicate trends for investors to switch strategies [1][3] - The findings indicate that while small value stocks have historically outperformed large growth stocks, recent trends show a dominance of growth stocks, particularly during technological booms [3][42] Group 1: Value vs. Growth Investing - Value investing, as introduced by Graham and Dodd, posits that stock prices can deviate from intrinsic values, allowing investors to benefit from purchasing undervalued companies [2][5] - Academic research supports that high book-to-market ratio stocks (value stocks) tend to yield higher average returns compared to low book-to-market ratio stocks (growth stocks) [7][8] Group 2: Historical Performance Trends - Financial markets experience periods where growth stocks outperform value stocks, often linked to technological advancements, with the "Magnificent Seven" being a recent example [3][8] - Historical data suggests that periods of growth dominance are typically temporary, with expectations of a potential shift back to small value stocks as market leadership changes [3][42] Group 3: Methodology and Data Analysis - The analysis utilizes Fama-French portfolio datasets, employing both 2×3 and 5×5 portfolio constructions to assess the performance of small value versus large growth stocks [10][11] - The study constructs a spread factor (SV–LG) by taking long positions in small value stocks and short positions in large growth stocks, analyzing its long-term performance with trend-following signals [12][20] Group 4: Empirical Results - The results indicate that the long-only strategy on the small value minus large growth spread is the most robust, with historical performance showing distinct periods of strong value outperformance [14][30] - The analysis reveals that the spread has been largely flat since 2008, indicating challenges in timing the outperformance of small value stocks relative to large growth stocks [30][41] Group 5: Systematic Strategies - Trend-following strategies using moving averages show some ability to capture value outperformance, but timing the short side is significantly more challenging [29][30] - The study finds that strong outperformance of the SV–LG strategy has occurred during specific historical periods, particularly following major technology bubble bursts [30][41]
