Using the same techniques as in my other Fear & Greed (FGMR) strategies, I found through some trial and error a strategy for SOX, SOXX, SOXL, SMH that does not fire that often, but has a great win-rate. Although I will point out that win-rate is not everything, capital preservation and small losses and big winners is more important.

NOTE: at this time, us as a long-only strategy. If you find short settings that work, leave a comment and I can update this posting.

P&L look at the strategy

Note, as of 5/22/2019, the strategy is currently long 2 units (rare) and at favorable prices.

@Koygill, Can you explain what do you mean by long-only strategy and please let us know this will work for all stocks?

@San means only trade SOX long with the provided strategy that has settings tuned specifically for SOX. I could not find meaningful values to add to the P&L with short positions. As for other symbols, each one acts a little different and benefits from back testing specific to that symbol. As a general rule, FGMR should apply everywhere and 2.0/-2.0 BB% is a good place to start. See my other FGMR work (which is derived from original works from Kerberos007 on twitter).

Can you explain this like I'm 5 or an idiot. Which I am. So this signal means buy SOX today? Or as of the day of the signal? Is it still a buy?

@Tominatorxx Generally, a good time to buy would be on the day of the signal.
