If you believe that, then you should buy more. MUCH more.
Me...
Too late I did my buying when AMD was, split adjusted, somewhere in the $4 to $6 range. I say that because I've made too many trades to know exactly what my buyin price is without a lot of work. Tax free accounts and such.
Here's you first lesson in good investing. It's better to buy a stock that goes to $30 at $3 rather than $15. Hint, it's the difference between a 10 bagger and a 2 bagger.
I'd be happy to include more helpful hints if you would like?
