U.S. equity markets are trading broadly higher today after a strong trading session in overseas markets. The primary news driving investor enthusiasm is European Central Bank President Mario Draghi's statements indicating that policymakers are prepared to take coordinated action to support the European economy. Fears of a protracted European recession have weighed on U.S. stocks for weeks, and in response all 30 members of the Dow Jones Industrial Average (INDEX: ^DJI) are up on the day. Here's a snapshot of how the major domestic indexes were faring in the past hour.

Leading the Dow is Bank of America (NYSE: BAC), whose shares are up over 5% in morning trading. The rally follows an announcement yesterday that the company sold mortgage servicing rights on more than $10 billion in assets, furthering the company's continuing efforts to focus on core banking operations.

Shares of Home Depot (NYSE: HD) are also trading higher, up more than 2% following a company news release confirming full-year guidance and updating longer-term goals. Specifically, the home improvement retailer is now targeting operating margins of 12% by fiscal 2015. The company's operating margin was 9.7% in the past 12 months, with its best operating margin in recent history being 11.9% in 2006. Additionally, the company increased its 2012 share repurchase expectations by $500 million to $4 billion. Expect more information on the company's plans to hit the headlines later today following the conclusion of its investor day.

Drug company Merck (NYSE: MRK) is also making headlines today after its application for bone cancer drug ridaforlimus was temporarily rejected by the FDA. The news isn't all that bad for Merck and partner Ariad Pharmaceuticals (Nasdaq: ARIA), and the drug can still receive approval following additional clinical trials. The rejection was largely expected by investors, with the real opportunity for Ariad being upcoming leukemia drug ponatinib, which may be on the market this time next year and is expected to be a breakthrough drug for the company. Shares in both companies are reacting with a yawn, as both Merck and Ariad are trading higher on the day.
