Does SMA 20/50 cross actually work on NVDA? We tested it

This strategy made a lot of money, turning a 1379% total return on NVDA using a simple SMA crossover. However, the ride was extremely lumpy and painful, with a massive 63.63% drawdown that lasted over a year from late 2021 through the end of 2022. That single drawdown period was where the strategy hurt most, and it shows that the system can suffer deep, prolonged losses even though it wins 64% of its trades. The entry timing is a major strength here, since the real entries beat 92% of random entry runs, meaning the signal itself is doing the heavy lifting rather than the exits. The edge also appears to be consistent, as the strategy was profitable in all four walk-forward test periods, so the result is not just from one lucky stretch.
