@starkstechnology: A backtest is NOT a crystal ball 🔮 It's a historical replay of your strategy—and it's inherently biased. You already know NVIDIA crushed it. That's why you built an AI stock strategy. But next year might not be AI. It could be nuclear, green energy, or banks. A strategy that dominates in a bull market can lose 70-80% in a bear market while the S&P only drops 20%. Test your strategy. But don't trust the backtest blindly.
