I initially bought in at something like $88.60 per share in early 2005. Then it did a 2:1 split soon thereafter. I remember buying some more in the high $30 range. And then, as it would rise and fall, I'd buy and sell a bit more here and there.
In retrospect, I probably should have put everything I had on Apple back then, and just left it alone, but hindsight is always 20/20. And I know I would've been sweating bullets in 2008, when it went from just over $200/sh down to around $100. But, I lost half of everything during that plunge, anyway...
