> So I assume based on your strategy you put all of your money in AMZN 10 years ago, sold it right before each drop, re-bought right before each rise, and are now filthy rich. Oh you're not? I wonder why. No, that's just a buy-and-hold... just the same as an index fund. I didn't cherry pick anything. Plenty of high profile stocks went up more than 72% in the last 10 years. They're not even hard to find.

Of course it's not hard to find stocks today that went up over 72% in the PREVIOUS 10 years. That's not the problem. The problem is how do you pick the ones that will beat the market beforehand, when everybody has access to the same information about the prospects for future growth & earnings? It's been proven by hundreds of studies to be a statistical near-impossibility over long periods of time. Any outperformance over the short term can be mathematically reframed as random luck (which a retail investor like you and I will incorrectly attribute to being the result of our own abilities).
