Style investors recently witnessed a rare event when, on February 13th, the P/E ratio of the S&P 500 Growth Index fell below that of the S&P 500 Value Index. At first glance, it is tempting to attribute this valuation flip-flop to the 2022 bear market, which saw Value outperform Growth by a whopping 24.2%. However, the bear-induced collapse of Growth stock prices in 2022 only served to return the P/E spread to a level just below its historical median of 5.1, meaning that the final move toward parity was caused by a force outside the market itself. That “something else” was the S&P 500 style reconstitution that occurs annually on the third Friday of December.
Is the performance of certain countries mainly driven by particular sectors? And, does U.S. sector performance drive the performance of other countries? (i.e., when U.S. Financials underperform, do foreign countries with large Financials sector weights underperform?). We did some data crunching to address the second question.
Portfolio managers who tilt toward Value or Growth stocks have long known that each style carries with it an inherent bias toward some sectors and away from others. Our recent piece, Value Style’s 100-Year Flood, highlighted the significant role that sector weights (overweight Financials and Energy, underweight Technology) played in Value’s decade-long stretch of underperformance.
