Just received this from my broker for the shares just purchased at close today! Seems like they are desperate to offer shares short...:-) Dear Trader, You could earn extra income on the fully-paid shares of stock held in your account by joining IB's Stock Yield Enhancement Program. This plan allows IB to borrow shares from you in exchange for cash collateral, and then lend the shares to traders who want to sell them short and are willing to pay interest to borrow them. Each day that your stock is on loan, you will be paid interest on the cash collateral posted to your account for the loan based on market rates.
