On CNBC's "Mad Money Lightning Round," Jim Cramer recommended buying BHP Group (NYSE:BHP), adding that it's a "very well-run" company.

On Nov. 20, BHP announced plans to invest up to $14 billion to enhance its copper production in Chile, as revealed during a three-day site tour of its operations. This substantial capital expenditure aims to secure the long-term future of its assets in the region and support the growing global demand for copper.

Cramer said Diamondback Energy, Inc. (NASDAQ:FANG) is a buy.

On Nov. 4, Diamondback Energy reported quarterly earnings of $3.38 per share, which missed the analyst consensus estimate of $3.99 per share. The company reported quarterly sales of $2.65 billion which beat the analyst consensus estimate of $2.44 billion.

When asked about AMC Entertainment (NYSE:AMC), he said, "If it gets to six, I want you to sell it. Period. End of story."

On Nov. 12, the company disclosed a debt retirement move in a SEC filing. The company said it entered into a series of privately negotiated agreements to retire $24.22 million in unsecured debt through 5.75% subordinated notes due 2025 between Nov. 8 and Nov. 12.

Copart, Inc. (NASDAQ:CPRT) is a "remarkable" company, Cramer said. "I need to see a pullback in Copart."

On Nov. 21, Copart reported better-than-expected sales results for the first quarter.
