There wasn't any major market-moving news today. Not that that stops folks from assigning a reason for the good day in the market.

Some of those people will point to Europe and the generally favorable news: (1) Fitch Ratings reiterating that it doesn't expect to downgrade France from AAA and waxing favorable on the current path of European actions, (2) the euro rising for a second consecutive day, and (3) key European stock markets rising for the day.

Although there weren't any major earnings announcements today, the Dow's early reporter, Alcoa (NYSE: AA), reported yesterday, pleasing investors despite tallying a slight loss for the quarter. It beat sales estimates and gave a favorable aluminum demand forecast for 2012.

While Alcoa gained 2.9% yesterday before reporting and was pretty flat today, the big winner was Bank of America (NYSE: BAC), up 5.7% today. It's already up 19.2% year to date after a woeful 2011 saw it lag all other Dow stocks. There were no big losers, as 23 of the 30 Dow stocks gained for the day and none of the losers lost more than 0.7% (GE and Cisco).

It was another great day for Bank of America, but remember to keep its hot streak and all the other daily noise in perspective. Invest for the long term.
