The Oakmark Fund increased in value by 5% for the three months ended March 31, 2011. Though good as an absolute return, our return slightly trailed the S&P 500 gain of 6%.

The biggest reason we didn’t quite keep up with the S&P was the strength of the energy sector. During the quarter, the price of oil increased by 17% (West Texas) or 24% (North Sea Brent), depending on which measure one uses. Commodity businesses, understandably, tend to perform quite well when the commodity they sell experiences such a price spike. For the quarter, the average energy stock increased two to three times as much as the S&P did, and our portfolio wasn’t as heavily weighted in those stocks. We don’t believe this higher price of oil reflects a long-term market-clearing price and, for that reason, we value oil stocks using an assumption thatoil prices will fall. In our valuations, most oil companies are priced less attractively than other businesses are, and we are comfortable continuing to own just the few we have.

Returns of individual stocks in the portfolio followed the typical pattern for successful quarters—more winners than losers, and gains of greater magnitude than losses. The Fund had 18 double-digit gains and only two double-digit losses. The biggest losses were suffered by Cisco Systems (-15%) and Best Buy (-16%). Both reported disappointing operating results, and we are revisiting our long-term forecasts. In both cases, we believe that the stocks remain attractive.

On the positive side we had seven stocks that gained more than our largest loser lost: DirecTV (+17%), Viacom (+18%), Cenovus (+19%), EnCana (+19%), Capital One (+22%), Harley Davidson (+23%) and H&R Block (+42%). Block had been one of our weakest stocks in previous quarters, but snapped back nicely as early tax results exceeded expectations and lingering subprime mortgage losses remained trivial.

During the quarter, we neither added any new positions nor eliminated any positions that were owned at the end of 2010. However, we did receive one new security via corporate action: Huntington Ingalls Industries was spun off from Northrop Grumman. Our numbers showed Huntington trading at a substantial premium when comparing its total capitalization (including debt) to the pretax, pre-interest cash flow it generates. For that reason, we sold our shares in Huntington and used the proceeds to increase our Northrop position. In addition to Northrop, we also added substantially to our positions in Unilever, Aflac and FedEx.

Thank you for your continuing support.
