In one corner of the Treasury exchange-traded fund market, it’s a golden cross. The $17.3 billion iShares 20+ Year Treasury Bond ETF’s 50-day moving average moved above its 200-day counterpart on Thursday for the first time in more than two years, a bullish chart pattern for some investors. The fund is heading toward its third month of inflows, the longest stretch since February 2020. Still, with most Federal Reserve officials seeing the tapering of the central bank’s pandemic-fueled bond purchases this year, “the cross might fail,” said Bloomberg Intelligence strategist. “Of course, risk-off could mean that TLT keeps rallying.”
