Studies by industry group,
DALBAR, suggest that over the last 20 years
ending in 2020, equity mutual fund investors have captured only 80% of
the return of the U.S. stock market, as represented by the S&P 500
Index. Bond investors fared even worse according to this study. The
employees of Stringer Asset Management have dedicated their careers
to helping investors close the gap between the opportunities that the
financial markets present and the returns that investors actually realize.
