ALISON KOSIK, CNN BUSINESS CORRESPONDENT: The winning Tuesday streak on Wall Street may be coming to an end. With just about 20 minutes to go before the closing bell, stocks are deep in negative territory. From the New York Stock Exchange, I'm Alison Kosik and this is "Your Money." The Dow is trading lower by about 40 points right now. Leading up to today, the Dow has closed higher for the past 20 Tuesdays in a row, gaining 1,500 points in the process. That's about double the increase we've seen on Fridays, the next best day for the market. There are lots of theories on why Tuesdays this year have generally been a winning one for stocks. Some say it could be mutual funds not clearing their weekend orders until late Monday or early Tuesday. Others say algorithms recognize the trend and buy on Tuesday. It has become a self-sustaining phenomenon. Some say people just don't like Mondays, so when stocks fall on Monday, Tuesday is a natural reversal, while others say there is just no rhyme or reason at all to it. As for today, analysts say the pullback could just be a continuation of the big drop we saw on Friday, or investors putting their money out ahead of the May jobs report coming at the end of the week. There are also still worries that the Federal Reserve could pull back on its stimulus measures sooner than hoped. One share that is making progress today, General Motors. Shares of G.M. are up about one-and-a-half percent right now. This week, the automaker is making a return to the S&P; 500 after getting the boot when it went bankrupt in 2009. It will replace Heinz, which is going private. That's it for me. Watch "Your Money" with Christine Romans, Saturdays at 9:30 a.m. and 2:00 p.m. Eastern, or Sunday at 3:00 p.m. Brooke Baldwin is coming back after the break.
