Oak Ridge Investments Portfolio holdings
Oak Ridge Investments is an equity manager that mostly picks U.S.-listed stocks, with five growth and dividend strategies from all cap to small cap. David Klaskin founded the firm in 1989 and is its chief executive and a majority owner. Oak Ridge looks for companies whose earnings growth, strong fundamentals and reasonable valuation should drive long-term share price gains. Pioneer Investment Management USA once held a minority stake, which Oak Ridge later bought back to become fully employee-owned.
