If you have been investing for years and think that "a system with a proven edge" exists, then you are the minnow who doesn't know what he is doing.
Hoping is not a strategy either. It has taken me a decade to learn the IPO syndication, which constitutes a small, tactical portion of an overall well diversified portfolio.
And what does capitalization have to do with this? Everyone got FB at the same $38 IPO price regardless of how many shares they received.....and yet those smart enough not to hold it made good money...while many well capitalized huge investors are down 30 percent and still holding the bag. Doesn't sound like it is rigged or that I lost to me.
I agree blind dabbling and day trading isn't a good idea. Neither is losing purchasing power to inflation via sitting in cash earning nothing. That is the surest way to lose. Long term investing and diversification are the best bet, and that is a proven fact.
