quarter profit. Both income and revenue beat Wall Street's expectations. The lender got a boost from improving results in its Citi Holdings unit, which is selling off assets such as mortgages that soured in the financial crisis. Citi's shares surged $1.90, or 4.2 percent, to $47.58. POSITIVE PROGNOSIS: WebMD said it expects to report strong first-quarter results at the end of the month and anticipates reaching the upper end of its annual earnings and revenue projections. The health website operator's stock climbed $6.03, or 16 percent, to $43.70. SECTOR WATCH: All 10 sectors in the S&P 500 index rose, led by energy stocks. HEART STOPPER: Medical device maker Edwards Lifesciences rose the most of any stock in the S&P 500 index. A federal judge on Friday reaffirmed an earlier ruling that Medtronic's CoreValve system infringes on Edwards' patent for a replacement heart valve. Edwards soared $8.36, or 11.5 percent, to $81.33. Medtronic fell $1.28, or 2.2 percent, to 57.93. OIL BOOM: Goodrich Petroleum got a big boost Monday when it reported results from a well in Louisiana. Shares rose $5.31, or 28.9 percent, to $23.72. The stock is up 39 percent this year. The latest gains build on an impressive turnaround by the oil and gas producer, whose shares fell for four straight years from 2009 through 2012. The stock began bouncing back last year. STOCK SPOTLIGHT: Among the biggest risers in midday trading were Micron Technology, up 94 cents, or 4.4 percent, to $22.07, and MasterCard, which added $3, or 4.4 percent, to $71.68. Decliners included Intuitive Surgical, which shed $14.12, or 3.1 percent, to $425.50. Gap slipped 78 cents, or 2 percent, to $37.62. EARNINGS RADAR: Citi's solid quarter and the encouraging earnings outlook by WebMD were welcome surprises after an earnings miss last week by JPMorgan Chase that got the first-quarter earnings season off to a sluggish start. Analysts still expect first-quarter earnings for companies in the Standard & Poor's 500 to decline 1.6 percent from a year earlier, according to FactSet, a financial data provider. If profits do fall, it would be only the second quarterly drop in three years. Among the major companies due to report earnings this week are Johnson & Johnson, Google, General Electric and UnitedHealth. BONDS AND COMMODITIES: In government bond trading, the yield on the 10-year Treasury note inched up to 2.64 percent from 2.63 percent late Friday. The price of crude oil rose 31 cents to close at $104.05 a barrel. Gold rose $8.50 to settle at $1,327.50 an ounce. -- SPA 00:19 LOCAL TIME 21:19 GMT تغريد
