I usually check technical charts if it's OK, then go for fundamental for any good reasons. That's the basic, but sometimes I do short, swing or day tradings if there's opportunity. Like at MER, CYBR, FPH etc. this company are so volatile in past few days, all technical chart basis are saying NO, but as we seen, lot of traders made huge profit also since last two weeks here.
I'm doing this way since I'm a trader, not an investor. And every trader has it's own unique ways how to dealt the market. There's no one can says you're wrong or right, in the end, it's only your money loss then.
The higher the risk, the higher profit to rip... so consider me a risk taker.
