Sold UTEK - 2 Years... 57% Gain

I just sold one of my Prudent stocks today... Ultratech Stepper (UTEK). I bought this about two years ago for $15.70 and I just sold it today for $24.70. The folks at Prudent believe it could go to $35 or $36, but I've had enough... too much volatility. Just look at a two year chart:




A chart like this gives me heartburn and it's not worth the potential upside. I'm taking my annualized return of %25 and running to the nearest value stock or ETF.
