[According to a Reuters story, reported on CNBC about 2:45pm ET:]The Federal Reserve discount window is now open to Fannie Mae and Freddie Mac. Both stocks, which were down by huge percentages, began climbing. And the Dow has moved from down 250 points earlier today to down 100 points at 2:50ET.
UPDATE: Now Reuters is backing off the story and the DOW, which went positive at about 3:05pm ET, is off 140 points at 3:40pm ET. This week, rumors are flying on Wall Street (there was a phony one about Lehman earlier this week).
