Although there are many; RSW and only TECS have performance ratings IMO DOG is ONE to ONE.
Best BET? Buy a long dated deep ITM put option on TECL which would return 3 X more than only holding TECS at 3 X returns.
The trend for Minerals is about to change; it/they will trade against the markets, it starts now!
I was studying AGQ from another person that suggested it, but, USLV popped up on my radar while studying AGQ. Still doing the analysis on USLV, "IMO, Buy SLV when it trades very near to 28.28", buying USLV which is 3 X SLV would perform rather nicely.
As I have only begun to study USLV; If USLV trades options, buying the longest extended Call Options best bet; I would buy the longest dated deep ITM call options; the effect would be 3 X better than holding USLV which only offers 3 X SLV
IMO; Watch 28.00 carefully on SLV!
