He likely bought more.
AAPL has easily outperformed the market since Cook took over even with the recent slide, so not sure what you're upset about.
Unless it is a hyperbole, the 1000% is a mockable statement. I think Green Mountain went up by more than 1000% early on - missed that boat.
AAPL has done great in the market - my purchases are at $10 in 2002, and ~$95 two years ago.
Are you factoring "Splits" in there? I am no math wiz, and I CERTAINLY suck at math (and, apparently, the calendar, too!); but I was just thinking of how much the value of, say, 10 shares of AAPL would be worth in 1997 vs. now. Obviously, that isn't the 6 years I quoted... Sorry!
My 00's stock split 14:1 overall, and went by 7X at the latest split. The growth was $10-700.
Since the split it multiplied by ~3 at the max (70 -233). So, 70X3 ~ 210X from 2001!
Not thousands.
More profit in day-trading this stock - something I'm sure is in Buffett's zone.
