Squawkbox market analysis with Danielle Morellino from Thomson FinancialTranscript:Welcome to this week's Thomson Squawk Box On the Radar Report. I'm Danielle Morellino.Our Thomson Squawk Box team thinks it's just a matter of time before shares of Mastercard are hit due to a weakening global economy. New York based MasterCard, the global payment solutions company, reported blowout numbers last week but failed to break through to new all-time highs. As a result, there may be opportunity for short sellers to profit.The stock has been locked in a trading range since October 2007. During the last four months MasterCard has traded between $227 on the upside and $160 on the downside. We feel that since the stock could not break above $227 in spite of great numbers, it is signal for short sellers to pounce. Shorts were crushed last week as traders were anticipating bad numbers after American Express reported disappointing earnings. But in subsequent days, shares rose to as high as $222 from $190 as the shorts rushed to buy back their shares after Mastercard's better than expected earnings. The company announced quarterly earnings of 89 cents a share, a positive surprise of 22.9% above the consensus 72 cents. Betting against Mastercard hasn't worked in the past. Over the past 7 quarters, the company has reported 7 positive, 0 negative, and 0 in-line surprises. The average surprise for this time period has been 26.4%. Yet we think that this stock is now priced to perfection. Nineteen street analysts have a First Call Mean of a buy on the shares. Mastercard's current quarter consensus estimate has increased over the past 90 days from a dollar 87 to a dollar 91, up 7.5% percent. Over the past 90 days, the consensus price target for Mastercard has increased notably from 195.85 to 239.83, a gain of 22.5 percent. All this bullishness sets up Mastercard for a potential fall, as traders and analysts fail to heed warning signs. On its last conference call, the company said that continued economic weakness has the potential to slow its growth. Perhaps more importantly, expenses increased significantly in the fourth quarter and the CEO clearly stated on the call that he sees business slowing down.The company is trading at the high end of the 5 year range based on Price to Earnings, Price to Book, Price to Cash Flow, and Price to Sales.Yet the stock has failed to break new highs, something we'd expect for a stock with such a lofty valuation. Something has to give, and it just may be the price action.Visit Thomson Squawk Box dot come for directional commentary and specific intraday swing and position trading ideas, delivered in real-time.
