TBT, the short TLT 20 year bond ticker looks neutral in the short term and bullish in the longer term. High volume breakout of descending pattern down, and now a bull flag set up. A high volume spike and a stopping bar down has preceded a move up twice over the the last year.
This is speculation over higher rates in the general market and from the fed, which would be correlated with lower equity valuations based on DCFs and opportunity costs associated with being in stocks vs bonds.
