We have another new leader as TheStreet.com's Beat the Street contest enters its final day.
"Mardan59" used an all-short portfolio made up mostly of "credit-crisis" plays such as mortgage insurers and banks to take over the top spot.
The portfolio, which totaled $302,696.90 after Thursday trading, consists of MBIA (MBI - Get Report), PMI Group (PMI), MGIC (MGIC - Get Report), Washington Mutual (WM - Get Report), MF Global (MF) and UAL (UAUA).
The contestants are playing for a $5,000 prize. Check back tomorrow evening to see who won.
