Bonds, and bond exchange traded funds (ETFs) are a good place for investors to hang out and park their cash in uncertain times.
ETFs that invest in short-term Treasury bills are known for being one of the safest types of investments. SPDR Lehman 1-3 Month Treasury Bill ETF (BIL) invests in short-term Treasury bills and has an expense ratio of 0.14%, so most of the yield goes into your pocket.
Current yield, which can be calculated here, is an important indicator of a Treasury bill and if it’s a good time to go in. The only disadvantage of an ETF Treasury bill fund is that you have to pay a brokerage commission to buy and sell.
