Advisors' Opinion:

• [By Peter Leeds]

  Based on percentages coming in from 9 battle ground states, and the number of electoral college votes from each, it appears that Obama would win if the election were held today.  I expect his lead to increase as the campaign enters full swing.

  One company that could benefit from a few more years of a Democratic president would be Ariad Pharmaceuticals (ARIA 0.00%).  It is a pharmaceutical company that earned $13.9 million in the third quarter (10 cents per share), and sits on an impressive $86 million in cash. The Bush administration fought against stem cell research, which is a big part of Ariad's approach, and the company and its shares were hammered. Now, after several years of friendlier policies, and the prospect of another four, Ariad is building momentum and gobbling up market share. I think it could trade up to $16.20.

• [By Hilary Kramer]

  Ariad Pharmaceuticals (NASDAQ:ARIA) is developing novel cancer treatments, and it has three promising drugs in its pipeline: ridaforolimus (which I expect to get FDA approval shortly), ponatinib (recently reported good Stage I/II results), and AP-26113 (a compound with strong potential that just started clinical testing). The stock is up nearly 50% since the early October lows, and while concerns over the possibility that Ariad will raise money could be a short-term overhang on the stock, I look for share prices to continue to climb as the company’s drugs move through the approval process.
