FSG is a defunct ETF that was interesting.
2x leveraged GLD.
AND 2x leveraged SDS.
Up if gold rises and/or SPX falls.
I keep up the chart using UGL/SSO.
Tradeable buy signals last Dec, Mar, July and now.
Its the weakest of the four in several respects, so don’t lunge.
But it does suggest something is finally afoot.

Addendum: In addition to FSG, I have similar signals for SLV and SILJ.
But not for GLD, GDX, J, GOEX or SIL. Could all be close though.
