It's risky to directly connect stock prices with national election results, but for what it's worth, shares of both Amgen and Northrop - two local companies that could be impacted by a Democratic-controlled Congress - are off this morning. Northrop is down 1.25 percent, to $65.57. (Another wrinkle in Northrop stock could be the resignation this morning of DOD Secretary Donald Rumsfeld.) Amgen is down 0.68 percent, to $74.70. Besides the political fallout, the Thousand Oaks-based biotech company could also have been hurt by tax problems announced this morning at Merck.
