CNBC’s Jim Cramer said Monday that if the Federal Reserve leaves rates unchanged at this week’s meeting, investors should consider buying some industrial and energy stocks.

“If, like me, you think the Fed will keep the fires going, you want to own a steel stock or a heavy machinery plant or a chemical company,” Cramer told Mad Money. “I even sanction some energy stocks because a lot of these companies have changed their sub-optimal course of action.”

Cramer advised investors to look at stocks like chemical maker Dow Inc, heavy machinery company Caterpillar, and Cleveland-Cliffs, maker of iron ore and steel products, which fell 9% on Monday. Dow Inc and Caterpillar also fell slightly on Monday. He also pointed to energy stocks Chevron, Exxon Mobil and Pioneer Natural Resources as potential buyers for investors.

“These are the companies that thrive when economies around the world grow, and that’s exactly what I expect,” said Cramer.

The Fed is expected to begin its two-day monetary policy meeting on Tuesday. The central bank is not expected to change rates. However, investors will be looking for clues as to whether the Fed has changed its stance on US inflation. The meeting is expected to close on Wednesday.

Cramer’s comments came after growth gains and technology names drove the Nasdaq Composite to a new record close. The S&P 500 staged a late day rally and also closed at an all-time high. The Dow Jones Industrial Average lagged and closed a little lower.

Monday’s moves in growth stocks – like social media giant Facebook, cloud messaging platform Twilio, cybersecurity provider CrowdStrike, and e-commerce site Etsy – portrayed belief that the economy could cool, or the Fed Could raise interest rates to keep the economy from overheating, Cramer said.

CrowdStrike shares were up about 1% while Facebook was up 1.7%. Etsy was up 2.7% and Twilio was up 3%.

“Until we see … the whites of the [Fed’s] Eyes on Wednesday, you can expect the action to look like it did today when we had a lot of traffic in the junior and senior growth aisles and buyers fled the messy industrial aisles and bank warehouse aisles, ”he said.
