High unemployment and sluggish growth in hiring-only 1.1 milllion jobs added in 2010 and only 103,000 in December 2010, according to the Labor Department- will restrict profit growth. Industries such as airlines, food, construction and telecom that lagged the recovery, will continue to face difficulties. Airlines face higher fuel prices and labor wage pressures. Standard and Poor's expects profits for the S&P 500 Index companies to reach a 3 year peak in the ist quarter 2011, then move lower for the next 5 quarters. Earnings reached $22.62 a share for these companies, up 29% from one year ago.
