We back-tested using data from 1984 to 2020. We also present that data in full with no editing or cherry-picking on our website. It’s free to review at www.thinkinglonger.com.
We don’t base our recommendations on sectors or any other criteria except price performance although we don’t include energy or utilities (too much government interference in price) or consumer counter-cyclicals (running against the very momentum we are trying to capture). FYI, we seem to do better in those years when the S&P 500 is weak or down.
Thanks for asking.
