24/7 Wall St.

Markets opened higher this morning following the pleasant surprise earnings report from Alcoa Inc. (NYSE: AA) after markets closed yesterday (our coverage here). The report on US crude oil inventories showed a relatively modest gain this week, boosting crude prices (our coverage here). Based on better expectations for quarterly earnings and mildly better news on the global economy, investors took on more risk today, driving up Treasury yields in the bargain. The US dollar index fell slightly today, now down -0.09% at 79.788. The GSCI commodity index is down about -1.5% at 674.42, with orange juice again leading the decliners. WTI crude oil closed up 1.7% at $102.70/barrel, and Brent crude trades up 0.12% at $120.02/barrel. Gold settled down just -$0.40 today, at $1,660.30/ounce.

The unofficial closing bells put the DJIA up more than 90 points to 12,806.15 (0.71%), the NASDAQ rose more than 25 points (0.84%) to 3,016.46, and the S&P 500 rose 0.75% or more than 10 points to 1,368.79.
