It can seem overwhelming. That is why it is better to stick with just a few things. You don’t need to know everything about a company or its stock, just enough so that you are confident enough to get into it.
You might want to just use a couple different analyses and see how they would have worked in the past or paper trade with them and see how they perform compared to the rest of the market. If it seems to work then maybe try it out with real money.
The idea is to just take a few things and create a system that suits you and you are confident in using, but you do not have to know everything to make money.
