The best time to start is with about 15k dollars, then stock traders will give you something like 30 free trades a month. Every trader has some kind of requirement for you to get free trades, so look that up first.
Personally, I stick with tech stocks, but dip into penny stocks here and there.
I'm assuming that what you're trying to do is invest in a company that you think will be big someday... it's tough to do it like that, but it's fine.
One of the main tenets I've noticed though, is that with stocks you really need to be able to invest a lot if you want to make a lot.
