Actually, no. If you have decent low fee trading, your expected gain is just scaled according to compound interest rules compared to holding for 10x the time. The volatility is much larger relative to the lower gain you got, so the simple classification, of keeping it in cash would have had more yield than the fund. So, the rule is not investing for 5+ years, but only investing as much as you can loose without feeling like a soon-dead human....
