SPY did better over the period: $1,000 invested on October 28, 2022 would be worth $2,052 versus $1,810 for BRK-B, a difference of $242. SPY also led over three years, gaining 82.7% versus BRK-B’s 59.1%, and posted stronger one-year and YTD returns. However, BRK-B had lower 12-month volatility at 14.6%? No—SPY was lower at 12.7%, while BRK-B’s worst drawdown was milder at -14.9% versus SPY’s -18.8%. The comparison matters because SPY delivered higher returns with lower recent volatility, though it experienced the deeper maximum drawdown. BRK-B’s lower correlation with SPY and differing monthly performance provide diversification benefits, but it trailed in 27 of the last 48 months overall.
