I bought AAPL (these are all split-adjusted prices) for $6.50, $12, $27, $58, $70, $88, $94, $103, $130, and just three weeks ago for $202 (ugh!).
It's at around $135 right now. I think its a good time to buy. Remember: buy damaged stocks, not damaged companies. Apple is one of the healthiest on the planet. The room for growth is limitless (due to their small marketshare in phones and computers). I do not think iPod sales will decrease. With future touches and shuffles, I think Apple will put many more iPods into hands of people who are still buying their first MP3 player or upgrading an old one.
I think the first half of 2008 might not do much for the stock (or the market in general) but I see AAPL back at $200 by the fall and $250 by the end of the year. When the economy recovers, and if Apple can sell 50 million iPhones in the next three years, while continuing to grow their computer biz in Europe and Asia I think it's easily a $600 stock in 36 months.
For those freaked out by the recent fall: I remember when the stock was around $90 a share and in three weeks it fell to something like $54. Everyone freaked out. People said the ride was over. The ride is not over until Apple becomes a damaged company.
I'd enjoy hearing any agreements/disagreements on this post.
