Why would I get out now when I didn't sell it for a $1 higher on friday? Any reason? You sell because your fair market price is $8. Better yet sell your home and short. You will be able to buy a house twice as big when MRVL is fairly priced.
When did stocks, let alone high growth tech stocks, start selling for book values? S&P would drop by 60-70% if stocks went down to their book values.
My estimate is very conservative. I am looking for a PEG of 1 which used to be unheard of for tech stocks, except for commodities like HDD. At 15% growth rate and $1.70 earnings for 2011 MRVL's one year target price is $25.50.
