Yesterday was the 6-year anniversary of my entry into the "beautiful" trade referenced above. On 2/10/2020 I cashed out ~10% of my investment portfolio and put it into S&P 500 April puts, a little more than a week before markets started crashing from COVID-19. The position first lost ~40% due to the market continuing to go up during that week, then went up to a peak of 30-50x (going by memory) before going to 0, with a final return of ~10x (due to partial exits along the way). After that, I dove into the markets and essentially traded full time for a couple of years, then ramped down my time/effort when the markets became seemingly more efficient over time (perhaps due to COVID stimulus money being lost / used up by retail traders), and as my portfolio outgrew smaller opportunities. (In other words, it became too hard to buy or sell enough stock/options in smaller companies without affecting its price. It seems underappreciated or not much talked about how much harder outperforming the market becomes as one's assets under management grows. Also this was almost entirely equities and options. I stayed away from trading bonds, crypto, or forex.)
Starting with no experience in active trading/investing (I was previously 100% in index funds), my portfolio has returned a total of ~9x over these 6 years. (So ~4.5x or ~350% after the initial doubling, vs 127% for S&P 500. Also this is a very rough estimate since my trades were scattered over many accounts and it's hard to back out the effects of other incomes and expenses, e.g. taxes.)
Of course without providing or analyzing the trade log (to show how much risk I was taking) it's still hard to rule out luck. And if it was skill I'm not sure how to explain it, except to say that I was doing a lot of trial and error (looking for apparent mispricings around various markets,
