DoubleLine Capital CEO Jeffrey Gundlach said the best way to navigate the extreme volatility in financial markets right now is to sell into equity rallies, particularly when the S & P 500 reaches a certain level. "The optimal strategy is to reduce risk on strength," Gundlach said on CNBC's " Closing Bell " Monday. "The markets are so volatile, so much movement that it's almost impossible to sell on weakness.
We're in a hiatus here," Gundlach said. He believes if the S & P 500 rises to the range between 4,200 and 4,300, it would be a good place for investors to sell. The large-cap equity benchmark is still in the green for the month, trading around 3,983 on Monday. .
