I don't know, I still don't see Apple as a bad investment. Their EPS has remained pretty good at $5.72 a share. P/E is at 28.46, which might be somewhat high, I haven't kept up on the industry average. The stock has traded anywhere from $78.20 to $180.45 during the last year and is at $162.79 currently. It certainly seems strong compared to some of the other tech sector stocks, but who knows. My guess is that over a year period Apple will probably see an increase in its stock price, if only to get back to what it was at pre-recession.
If you decide to invest in the market you need to buy more than just Apple stock. The key word in investing is diversification. Find some other companies you like in different areas and invest in them too. Hell, invest in some type of commodity or energy source if you can too. Putting all your eggs in one basket isn't the best way to invest, if you can select quite a few companies in many different areas you'll be able to minimize the impact of a catastrophe at the company level. If we have a market wide event, like the last recession, there isn't much you can do other than wait it out, but a diverse portfolio minimizes some of the risk at the single stock level.
You just have to remember that you might lose your money; its not a CD and nothing is guaranteed. You can't expect to win for sure in the short-term.
At his age he has more risk tolerance than almost anyone; if he sustains a large hit he has his whole life to make the money back. Unless, of course, we're talking about money you intend to use to pay college tuition, in which case you should definitely have some one with experience manage it.
Mutual funds are mutual funds, they aren't great, there can be some pretty high fees associated with them, but owning some as a regular part of your portfolio, in addition to stocks, bonds, and other investment tools, is a good idea.
I think the OP should start trading ForEx.
