Analysis of this style is going to be tremendously subject to survivorship bias. It's obvious that amongst the biggest winners will be some who took too much risk - with extreme variance the lucky few will wind up winning biggest. But there's no reason I should expect to be so lucky.

Meanwhile, I am most able to put away the most money when tech stocks are doing well, and most likely to have trouble finding work (and possibly need to tap my investments prematurely) in an environment where tech stocks are likely to be at their lowest. "Buy high and sell low" is a poor strategy.
