That sounds more like speculating than investing. I always view investing as simply a hedge against inflation rather than a true money making venture.

If you are investing put it in a low-cost index tracker sheltered in a tax efficient vehicle (in UK that would be ISA or private pension scheme). Let it compound forever. That's probably what I would do.

If you've not heard of him, look up Harry Browne. He recommended splitting your portfolio four ways: gold, cash, bonds, stocks. He reckoned that way you'd do OK no matter what was going on in the world.

If you feel more like speculating perhaps learn poker and take a trip to Vegas? ;)
