Sold roughly 30-40% or Riverbed Technology (RVBD) in our portfolios after the stock has ramped from $30 to $45 in weeks. RVBD is now trading at over 30x 2011 earnings which is getting pricey. Not that other stocks like Open Table (OPEN) aren't more expensive, but its getting risky to hold onto such huge gains. Still keeping a good percentage of the shares so we're not negative on the stock just the short term valuation.
RVBD had become the largest position by far in both the Growth and Opportunistic portfolios so pruning some shares became prudent for diversification purposes.
