It appears that the P-series preferred stock is the best bargain right now! This one has a face value of $1000.00 a piece, and is CONVERTIBLE into common stock at any time.
From the first link above: "The preferred shares are convertible any time at the holder's option into 20.0509 common shares of lehman Brothers Holdings Inc. (NYSE: LEH), an initial conversion price of $49.87 per common share."
So, if you buy 1000 shares of LEHPQ you pay now $1000-$1050 (as I did today). If you convert 1000 shares of LEHPQ into common stock (LEHMQ) you get 20,050 shares, which are trading right now at $0.245 a piece, meaning that you cash about $4900 (menus $30 processing fee). I am in the process of doing the conversion now (for half of the LEHPQ shares that I bought today). I hope that everything goes smoothly.
