Without quantifying the risks involved with your trading strategies, it is impossible to say whether you are beating the risk-adjusted returns of an index fund. Additionally, I am pretty sure index funds, even without risk adjustments, have been proven to be better investments in the long term than any actively managed strategy. And this holds regardless of the experience of the investors. There are always going to be a few exceptions to the rule, but most of the people getting rich in wall street are doing so because they are taking a cut of other peoples money (management fees), not because they are genius investors.
Also, with actively managed strategies, it only takes one or two bad bets to wipe out years of gains, and due to natural biases, individual investors tend to under-report/weight losses and over-report/weight the gains. As such, we always tend to hear how other investors are making a killing on a certain stock or trade, but we rarely hear from the losers, which distorts our perceptions of risk and returns (so far, I have seen a handful of people talk about their Tesla stock holdings on this thread, but I have yet to see a single person talk about haw bad they are getting cleaned out because they shorted the stock).
