Performance shown is backtested and hypothetical. It does not represent actual trading and may not reflect the impact that material economic and market factors might have had on decision-making. Backtested results are calculated from March 1996 through the most recent weekly data. Past performance is not indicative of future results. This is not investment advice. All investments carry risk, including possible loss of principal. The strategy uses survivorship-bias-aware constituent data — delisted and failed companies are included in the backtest.
