The markets opened lower this morning and not until mid-afternoon were equities able to put a mark above yesterday’s close. European stocks traded mixed all day, and that coupled with rising crude prices could have held the markets in check. Crude prices are upmore than 3% so far today, at about $102.55 for WTI crude. The good news is that the spread between WTI and Brent has narrowed to $9/barrel. Because US gasoline prices are now pegged to Brent, pump prices could rise only moderately as WTI continues to close the gap. The dollar is a bit stronger today as well, leading to lower prices among commodities, with wheat off by about -2.5%.The unofficial closing bells put the DJIA down more than 190 points to 11,905.19 (-1.57%), the NASDAQ fell more than 46 points (-1.73%) to 2,639.61, and the S&P 500 fell about -1.66% or nearly 21 points to 1,236.92.There were several analyst upgrades and downgrades today, including Dell Inc.
