Jim Cramer dished out his latest stock opinions on CNBC's "Mad Money Lightning Round" Wednesday, and he had some strong feelings about where investors should—and shouldn't—put their money right now.

First up: DigitalBridge Group, Inc. (DBRG). Cramer's verdict? Take a pass. "That's not the right stock for this moment," he said. The timing makes sense given that DigitalBridge's Digita Group just reached an agreement Tuesday to be acquired by GI Partners, creating some uncertainty around the company's direction.

When a viewer asked about Lumentum Holdings Inc. (LITE), Cramer gave it a measured thumbs-up with a caveat: "I'm going to say it's ok as long as you recognize it's a spec." Translation: sure, buy it if you want, but understand you're making a speculative bet. Mizuho analyst Vijay Rakesh seems more optimistic—he maintained an Outperform rating on November 25 and bumped his price target from $290 to $325.

But the real star of Cramer's commentary was MSCI Inc. (MSCI). He called it one of his "absolute favorite" stocks and praised it as a "complete winner." With shares down 9% year to date, Cramer sees a buying opportunity. The company did announce on November 17 that C.D. Baer Pettit, its president and chief operating officer, will retire in 2026, though that doesn't seem to dampen Cramer's enthusiasm.

Price Action:

• Lumentum shares rose 0.1% to settle at $302.98 on Tuesday.
• MSCI shares declined 0.3% to close at $545.56.
• DigitalBridge shares gained 3.8% to settle at $9.86 on Tuesday.
