Shares of General Electric, parent of NBC Universal, fell to a low of $22.16 Tuesday, their lowest level since February 2003, but ended the day at $25.06, up 1.9 percent over Monday's close, reversing a two-day 10-percent plunge. However, the downturn continued in early trading today (Wednesday) as GE shares traded at around $23.00, down another 8 percent. The plunge had little to do with the company's entertainment holdings, however, and much to do with its GE Capital subsidiary. Since Sunday's announcement of the bankruptcy of Lehman Brothers, investors have been reducing their exposure to the financial sector.
