Looking to retire around the year 2055. In my Roth IRA I am trying to decide between investing in the S&P 500 like Warren Buffett suggests or the 2055 Target Date Index Fund that Jeremy Schneider suggests. Looking at historical data of the two, it seems like the S&P 500 outperforms the TDIF by about double (with even lower expense ratio).
FDEWX (2055 TDIF):
1 year: +12.8%
5 year: +51.59%
~10 year: +101.11%
FXAIX (Fidelity 500 Index):
1 year: +24%
5 year: +100.08%
~10 year: +236.21%
Understandably the TDIF gradually shifts towards less risk, but is there any other reason to choose it over the S&P 500?
Or does it make sense to put 1/2 towards the TDIF and 1/2 towards the S&P 500? I know that the S&P 500 already makes up a significant portion of the TDIF so it doesn’t increase diversification, but it does sound like it would increase returns while also shifting half the portfolio towards less risk automatically.
