Speculation may have to finally take a back seat this week to substance as the glee from the latest rounds of monetary easing across the globe looks to be wearing thin. Earnings will be moving to the forefront of market sentiment after Alcoa (AA) kicked-off the earnings season last week. Traders will get a heavy dose of financial reports with more than 40 percent of the Dow components and 79 of the S&P 500 members releasing earnings from the latest quarter and guidance going forward.

Wall Street will also get a barrage of economic data from Washington and elsewhere in the country that will shed further light on the health of our country. Potentially market moving data will come from many key sectors and will include:

EIA Petroleum Status for the week ended October 13 at 10:30 AM ET – While this weekly report of oil inventories from the Energy Information Administration is often times not considered truly market moving, it has been particularly in focus lately as debates over supply versus demand have been hot button given the geopolitical turmoil in the Middle East.
