A stock is trading in the market at $471. An investor borrows 164 shares and sells them into the market. Interest rates are 4.27% and the borrow cost is 0.34%. Both are quoted as continuously compounded. The investor waits 15 days and buys back the shares at $332. Ignoring the fluctuating collateral position how much money did he make in total on the transaction? You need to compute both the profits/losses on the shares as well as the interest on the collateral. Round your answer to two decimal places.
