Typically, no. You don't get to vote for an index or mutual fund.

I've found stocks to be a fun thing to kind of collect. That company seems fun and stocks are $34. Eh, I'll buy one. And then just forget I have it. I don't do day trading or anything like that. So it's low stress and unless you are trying to buy a lot, relatively cheap. Occasionally you'll even get 24 cents back!
