Treasury yields are taking markets by storm. The yield on six-month Treasurys has surged past 5%, while the one-month is at 4.6%. The yield on the benchmark 10-year Treasury touched around 4% on Thursday. And a day earlier, the two-year yield hit its highest level since November. Because of that surge, investors are actually trying to bonds for yield — particularly short-term ones. There’s one other factor: stocks are floundering after a January rally. On top of that, investors are uncertain about whether the U.S. Federal Reserve will keep rates of interest higher for longer, provided that inflation has been proving hotter than expected . Short-term bonds appeal to investors who need to reap the benefits of higher yields for the time being, but don’t need to lock of their money in case markets bounce back — or if the Fed makes a dovish pivot. Investors with those preferences have also been flocking to short-term Treasury exchange-traded funds with durations of 1 to 3 years. Treasury ETFs are convenient in that they trade like stocks, track bonds closely and pay a daily dividend. Some examples include Vanguard Short-Term Treasury Index ETF and the Schwab Short-Term U.S. Treasury ETF. Top-rated, short-term bond ETFs But there’s one other corner of the short-term bond market with yields that would go even higher. CNBC Pro screened for top-rated, ultra-short term bond funds using Morningstar data. Criteria include a five-star rating from Morningstar, positive total returns over the past three years, and have a SEC (U.S. Securities and Exchange Commission) 30-day yield of greater than 4%. These mutual funds and ETFs showed up on the screen. A SEC 30-day yield shows the yield investors can earn over the course of a 12-month period — if the fund continued earning the identical rate for the remaining of the 12 months. Ultra-short term bond funds typically spend money on bonds with shorter durations of lower than a 12 months. They comprise a combination of presidency and investment-grade corporate bonds, or simply the latter. Some funds could get higher yield as they enterprise into riskier asset-backed securities. Keep in mind that corporate bonds bring more risk than government bonds since you might be buying corporate debt.
