Cramer brings together 5 industrial titles that he currently enjoys, including Boeing

Boeing, the aerospace giant, is in second place with its shares up 24% despite last week's sale and lingering concerns over how trade disputes could affect the company's business in China. .

But Boeing's business cycle "transcends the fluctuations of the economy in general," because its main factor is "the long-term rise of the global middle class," Cramer said.

As consumers in developing countries get rich, they spend more on luxury, including air travel, he said. This trend is directly related to the activities of Boeing and its only major commercial competitor, Airbus.

"That's why the demand for these aircraft far exceeds the supply." Two manufacturers! Boeing has given us a series of fantastic quarters – I think we'll have another one soon – but, more importantly, the company has nearly 5,900 aircraft in order book. […] It represents years and years of production, "he said. In short, the aerospace is so hot that I think Boeing is worth investing in weakness. "
