I have a fairly diversified portfolio in a cash account and I'm buying a little something everyday. I wonder how much I can make by making my portfolio available for stock loans. If I can make even an extra 2% a year that would be amazing. What has been your experience with IB's stock yield enhancement program? What kind of returns are your getting? Also, is cash in lieu of dividends guaranteed? So far I don't see any downside, it sounds too good to be true.
