It's about time. On Monda,y the Dow Jones Industrial Average (^DJI -0.11%) enjoyed a rare triple-digit rally, feeding off confidence that's been largely absent in the tenuous political environment leading up to the New Year. While ominous headlines about the fiscal cliff have dominated media coverage for weeks, today some hope was restored that a deal can be reached soon. House Speaker John Boehner reportedly conceded on an important point, bringing the White House and Congress closer to an ultimate agreement.

The concession? Rep. Boehner said Republicans would consider a tax increase on households with over $1 million in annual income. It's not groundbreaking by any means, but it's an instrumental baby step, and it was enough to boost the Dow by 100 points, or 0.76%, to close at 13,235.

Bank of America (BAC -0.13%) was far and away the biggest winner in the index today, surging by 4%. Shares are continuing an amazing run which has seen them nearly double thus far in 2012. Today's rise was part of a strong financial rally, as news broke that more U.S. banks are retaining the mortgages they originate, rather than bundling them up and reselling them. This speaks volumes for the increased confidence banks have in borrower quality, and therefore the housing market in general. That's good news for the U.S. economy.

Cisco Systems (CSCO 0.06%) was another Dow standout today, rising 1.3%. It appears investors are putting their money behind the tech giant's new marketing campaign, which attempts to rebrand Cisco as an innovator and groundbreaker, rather than a has-been relic of the '90s dot-com bubble.

Alas, not everything was all roses, and Hewlett-Packard (HPQ 1.55%) was the Dow's best example, tumbling 3.7%. It's nothing new for HP investors, who've seen the stock crater by more than 40% on the year. The catalyst today was new analysis from Deutsche Bank claiming activist investor Carl Icahn's planned breakup of HP would be a bum deal for company shareholders. 

3D Systems (DDD -0.86%), one of the few companies at the forefront of what very well may be a paradigm shift in manufacturing to 3-D printing technology, shot up 5.4% today. Of course, that's just a taste of the company's incredible 235% year-to-date returns. Who knows what kind of potential this industrial maverick has in store for 2013, but it's safe to say the stock is one to continue to watch.
