Value vs Growth factor. The names may be misleading, value actually has the better expected long term returns.

Look for "blend" funds instead.

Or even better, don't look at S&P 500. Look for total market instead (S&P 500 is a subset of the US total market) and ideally pair it with an extra fund. Total market would give you exposure to the "small" compensated risk factor and adding ex-US would remove the "single country" uncompensated risk factor.
