Marc Lasry, who made a fortune buying up troubled assets, told CNBC on Monday that investors who do not need returns right now should put money to work in the recent coronavirus-driven stock market slide.

"The market is definitely going to be higher at the end of the year," Lasry said on "Fast Money Halftime Report." But he said he believes there's going to be more near-term downside.

"You're never going to be able to time this thing," he said. "If you know that you don't have to sell next week, then I would absolutely be a buyer. Should you start coming into today? Absolutely."
