Stocks rose modestly on Wednesday after a Federal Reserve survey said the economy has gained strength, but oil prices near 2-1/2 year highs weighed on the market.
The Dow and the S&P 500 at one point turned negative as Brent crude rose above $117 a barrel after bombing raids struck near Libya's oil terminals.
But the market calmed down, and the Fed's Beige Book said U.S. economic activity slowly gained strength in 2011, with manufacturers and retailers were having some success in pushing their prices up.
The market is slowly adjusting to the new environment (of high oil prices) and beginning to realize that there is no short-term solution to this, that we are going to live with this uncertainty for a some time, said Robert Lutts, chief investment officer at Cabot Money Management in Salem, Massachusetts.
Stocks have taken their cue from oil since the start of turmoil in the Middle East and northern Africa in January. Investors fear rising oil prices could derail the economic recovery. For a graph of equities' correlation to oil, see http://r.reuters.com/mut38r
