Rule #2 of investing: Look at your investsments, and then go back to rule 1. Did you actually spread out your investsments? If not, do it!
Don't put more than 25% of your money in one stock, and only if you know for sure it will rise. 80% is crazy, and you should really start with small money until you get an idea of the market. Or go investments fonds.
Ive made some good money of AAPL, but I also bought the first time when it was at 30$.
Don't expect to make much, if any at all of AAPL until they release their next major product, ie. Car or health product which isnt a watch update, or a third magical one-more-thing.
