So far, 2020 has been a wild ride for stocks. The S&P 500 gained about 4.2 percent from January 1st to February 19th. Coronavirus fears plunged stocks 34 percent from mid-February to March 23rd. Stocks then soared about 61 percent, hitting a high on September 2nd. Then they dropped 6.2 percent over the following two weeks. Plenty of people might have wondered which funds were the best to buy during a rocky market. The folks at Kiplinger’s magazine touted five such funds last year.
