Trying to jump in and out of stocks doesn't have a high chance of success. Knowing some TA/chart backround would help, but trading is always risky.
I would find some stocks you like and stick with them. As Warren Buffett says, the big money is made by being patient. If the stock market seems too pricey then put a chunk into alternatives like bonds, gold, etc.
I see parallels between what you're trying to do (active trading of unfamiliar stocks) and what I tried in the past. There's definitely something to be said for keeping the money you have :o)
