Moreover, it's always easier said than done--after the fact. Why wasn't this posted 5 days ago? To say that you knew (or know now) that it would go up (or has gone up) nearly 100 points is downright amateurish. Get over it. It's only a noob's fantasy.
I agree, the point that I was trying to make was that even if you can buy at the bottom (which I know is impossible), it could be very hard to see 80% of your profits evaporate before the next run up.
