Given this backdrop, some may be surprised that the Mag 7 declined 11% in Q1, far more than the 1% loss for the S&P 493. Meanwhile, small value stocks were up 5%.2

What explains this disconnect? One possible answer is valuations. According to Vanguard’s Capital Markets Model, U.S. small caps (and to a lesser degree “value” stocks) were squarely undervalued compared to broad U.S. equities to start the year. Even after their strong relative returns in Q1, US small caps are still undervalued (21st percentile as of 3/31 vs. 12th percentile as of 12/31).3
