Todd Rosenbluth, head of research at VettaFi, says that American investors who have some $6 trillion in cash are in danger of missing out as the Federal Reserve begins to cut interest rates in coming months, meaning they should focus on what they are doing with their cash-like investments. That's why he made Fidelity Limited Term Bond his "ETF of the Week," noting that unexciting -- but in line with expectations -- is something investors should be striving for right now, so that they are protected when the rate picture changes. In The big Interview, Ben McMillan, chief investment officer at IDX Advisors, talks about how flexible bond-fund investors should be preparing for rate cuts and focusing in on duration plays -- where they are extending maturities right now to lock in current high rates -- while recognizing that credit quality will be a big factor in what happens when the cuts start happening.
