More encouraging economic news also helped equities Friday. The consumer sentiment index rose to a slightly better-than-expected 75.1 in February -- its highest level in eight months. Economists surveyed by Bloomberg expected the preliminary February sentiment reading would rise to 75 from 74.2 in January. The index was 74.5 in December, 71.6 in November and 67.7 in October. At the start of the recession in December 2007, the index stood at 88.9.
"In a Nice Band"
Consumers' outlook on inflation remained the same in February. The one-year inflation outlook was unchanged at 3.4% in February; the five-year inflation outlook, unchanged at 2.9%. Economists, business executives and policymakers monitor the consumer sentiment index because, historically, consumers' attitudes have correlated with their decisions to spend their income.
Despite some technical indicators to the contrary, Greco sees little risk of a major sell-off transpiring anytime soon.
"We're now in a nice band of the 1,310 to 1,320 range on the S&P 500" says the veteran New York Stock Exchange (NYX) trader. "I think there's more potential to move up. Not necessarily sharply, but to just expand."
