Guessing where the market might go was possible before the internet. A good sense of the public's wishes could help reveal the next opportunity.
Now - betting against computer and AI aided investment strategy, isn't a reasonable strategy. The big investment houses will always be a step ahead of you.
I read something recently that just might be the key to the puzzle. (Or tin-hat imagination, I don't know):
All of the big gains in the investment world, is the big guys betting against one another. The retail investor is sucked into 'investing' to earn a 'reasonable return' only because his money is needed to fund these large scale bets. In other words we're the sheep. While the giants go toe to toe using the funds we've provided them, to play with. True? I don't know.
