Cramer was really puzzled about the aerospace group this week. He decided to make it his mission to figure out if this group is peaking, because there is some serious money to be made or lost when it comes to the sector.
The aerospace stocks have been among the strongest out there. The space was suddenly called into question on Wednesday when Boeing reported a decent quarter, but then gave very weak guidance. Immediately, investors worried that the aerospace sector could be peaking, and Boeing's stock plunged almost 9 percent in a single session.
Even though Boeing got the most attention, there was also other bits of news that came out that had a much different takeaway. United Technologies issued a brighter outlook for its aerospace business. Additionally, Honeywell reported on Friday and reported similarly positive guidance, including in its aerospace division.
With these conflicting signals, Cramer boiled it down to two possible theories. Maybe the aerospace industry is peaking, and Boeing is just seeing it before the others.
"Or maybe, and this was my initial reaction to the weakness on Boeing, we are not seeing a peak in the industry at all," the "Mad Money" host said.

Even as Boeing struggles, Cramer reminded investors that some industries are likely to stay strong even if the market doesn't go back into bear territory.
One of those companies is Ethan Allen Interiors, as the home furnishings space has been pretty strong even after the Fed tightened. Ethan Allen is the chain of about 300 design centers that provide high-quality home décor, design and furnishings.
Although it has a somewhat inconsistent history, Ethan Allen reported a very strong quarter. Cramer spoke with the company's chairman and CEO, Farooq Kathwari, to hear more.
"When we take a look at the number of initiatives that we have had, first, of course, is our operating leverage. This vertical integration really makes a difference," Kathwari said.
In the Lightning Round, Cramer gave his take on caller favorite stocks:
Radian Group: "No. If I'm going to play housing, I'm going to play it now with Lennar. We had a fabulous move with Radian, but now we're back on Lennar."
Lannett: "I've got to tell you, I think you've got to be worried about that one. Buy it Friday if you really want to."
