ProShares UltraShort 20+ Year Treasury Bond ETF ( TBT) -2.0% TBT scored a spot on Wednesday's list of losers. However, by the end of Wednesday's trading, the fund managed to push into positive territory. These gains have been short-lived however as choppy market action drives investors back to the safety of long-term U.S. Treasuries. TBT appears to be on track to test its 50-day moving average. It has been a while since this leveraged product has spent a considerable amount of time above this point so looking to the next few days it will be interesting to see if it holds up.
