On CNBC's "Mad Money Lightning Round," Jim Cramer said Palantir Technologies Inc (NYSE:PLTR) is a buy. It has a special technology.

Las Vegas Sands Corp (NYSE:LVS) has too much exposure in Macao, said Cramer. He would rather buy Wynn Resorts, Limited (NASDAQ:WYNN).

Cramer likes Clearway Energy Inc (NYSE:CWEN). It has a good yield and it is safe, he said.

Energy Transfer LP Unit (NYSE:ET) is a recklessly run company according to Cramer, and he is surprised it hasn't changed the management.
