I think when bonds finally go into bear mode, if you are buying shares, buy TMV because of the triple leverage. If you are buying call options, TBT is the better bet. The TBT options are more liquid and the bid/ask spreads are much narrower as a consequence. I think now could be a good time, since a bullish inverted head and shoulders bottom may be forming in TBT and TMV. You can bu Feb. 25 TBT calls for about $.10 now ($10) per contract.
