Selling AAPL whenever possible

This algorithm sells AAPL whenever it can. Can anyone explain the numbers from the backtest to me, please?

In particular, how come the return is so high?

This questions comes up a lot...

You're shorting an unlimited amount of shares at a rate of 100 per trading minute.

As of yet, Quantopian does not stop you from borrowing more than is possible.

See this thread and this other thread for possible solutions.
