Question: is tbt a good investment?
Answer: It trades briskly and block liquidity is excellent. TBT's fees are also low for this segment, making it a cost-effective option for getting inverse exposure to T-bonds. TBT changed its underlying index from Bloomberg Barclays U.S. 20+ Year Treasury Bond Index to ICE U.S. Treasury 20+ Year Bond Index on 10/14/2016.
