Gordon, stock price is forward looking so you should use the projected profit over the next four quarters when calculating P/E. For a quick estimate I'll use the Yahoo! analyst summary here:
nothing...but if AMD starts posting $100 million per quarter then the stock will go up $4-5 dollars...if they continue posting $35 million net earnings the stock will go to $9-10 a share...the only way this stock is going to $5 a share is A) Massive terrorist attacks B)AMD starts losing money due to Intel basically giving flash at cost or below...
