Lesson for yourbestfrend on short selling at Fidelity
I have shorted millions of dollars worth of stocks over time and have never paid a single penny in interest. To short stocks and not pay interest, look at shorting as costing half as much as if you were buying the stock instead. Keep enough cash to cover the margin requirement and there are NO charges except the standard transaction commission. The cash you get for selling the borrowed shares does NOT apply to the margin requirement and you are under NO expiration deadlines.
