How many shares are you looking to purchase. Personally, if its only a few, I would hold off. Right now, its just shy of $200. If you buy 2 shares, thats $400. Plus the fee, its about 415-420ish. Now this stock is at its high, so moving up will most likely be slower right now, especially considering Apple is a fairly stable company.
The 1 year estimate (doesn't mean much) is at $206. So, lets just say by the end of the year, it reaches 210. 210x2=420. You didn't even make money. If you chose to sell, then you will actually lose money with the fees.
My non-expert recommendation: Buy their supplier's stock. What you should do is make a giant web with apple in the middle and just follow their supply chain outwards. The further out you go, the better return (also higher risk). Look for the small companies that just signed agreements with apple or something. These are the guys you can make a killing on. You buy a suppliers stock for $5-10 and they may shoot up to $10-15. Thats up to a 100% gain.
And you said you were looking for long term, I'm guessing more than 5 years. If this is the case, I would be questionable of apple. Sure, its a great company and all, but growth is limited the bigger you get. Hell, they don't even pay dividends, which many people look for in long term investments.
However, if you really want to buy this stock, great. Just don't buy it when its this high. Let it settle back down.
