Long-term yields might be the best bond investment this year, according to one exchange-traded fund expert. "The iShares 20-year Treasury ETF (TLT ) will get the biggest bang for its buck [and] some of the intermediate-term products like the Vanguard Intermediate-Term Corp Bond (VCIT ) will get some bang for the buck," VettaFi's Todd Rosenbluth told CNBC's "ETF Edge" on Monday. Rosenbluth added that while the short-term products were very popular last year, they will "largely tread water or earn a little more than their overall income." The firm's head of research reasons that if the Federal Reserve cuts interest rates more than expected then investors should stay in longer-term products to benefit. "We saw a lot of money start to move out of the short end of the curve into intermediate duration," said Slavin, the company's global head of ETFs.
