Good catch! It seems FCNTX is indeed better than SPY with sharpe ratio ~ 1.3 (vs SPY & QQQ 1), which is a better parameter than CAGR) imho.
The main risk seems it is an actively managed fund unlike passive index fund. So far, the management team have been adding value to the fund. Would that still be the case when the management team changes. That's NO when Peter Lynch retired ... 2 of 3 mangers are new as of 2025
Another would be tech heavy (50%)
Liquidity not as good as SPY
