That is how Hedge Funds win regardless of market direction. This is a very rough system too, since it is not on the efficient frontier. Even if you say that most of the profit comes from AMZN which is a high priced stock, true, but the point is that in terrible markets long/short tends to outperform just long - one tends to lose less on down markets, and still win on up markets, with reduced risk.
You still need decent timing, and good choices.
