short strategy - SI - 12-16-98

Start with a few shares at the beginning and double the shares for every 20%(approximate) move up in the stock. Buy back all when the stock move down 20%.

Example

10 shares short at 100$
20 shares short at 120$
40 shares short at 144$
80 shares short at 172$

when the stock drop back to 144$, buy back all 150 shares

Note: ALL IMO, and at your own risk using it. Mathematically and theoritically it works as almost all stocks will come down 20% at one time or another. Especially more so for volatile stocks like AMZN.
