US equity markets opened sharply lower this morning and continued falling before levelling off at around 200 pts down on the DJIA. The downturn followed closer examination of the European Union’s agreement last week which traders hoped would put an end to the debt crisis in Europe. That turned out not to be the case, however, with both Moody’s and Fitch Ratings expressing doubts about the permanence of the deal. An announcement of lowered guidance from Intel Corp. (NASDAQ: INTC) weighed on the tech sector. WTI crude oil is trading at $97.94/barrel shortly before today’s close, down about -1.5%, and gold is up about 1.85% at $1,744.50.

The unofficial closing bells put the DJIA down more than 162 points to 12,021.77 (-1.33%), the NASDAQ fell more than 34 points (-1.31%) to 2,612.26, and the S&P 500 fell nearly -1.5% or more than 18 points to 1,236.48.

There were several analyst upgrades and downgrades today, including Boeing Co. (NYSE: BA) raised to overweight with an $82 target price at Morgan Stanley. Other ratings actions today include AutoZone Inc. (NYSE: AZO) maintained as ‘buy’ with a $381 target price at Argus, E.I. du Pont de Nemours & Co. (NYSE: DD) cut to ‘neutral’ at Citigroup; El Paso Pipeline Partners L.P. (NYSE: ELB) started as ‘overweight’ at JPMorgan; Lennar Corp. (NYSE: LEN) and Toll Brothers, Inc. (NYSE: TOL) cut to ‘hold’ at KeyBanc.
