When Cramer took a look at the charts for many industrial and oil companies, he noticed something that they all had in common. All of these stocks were in an intense bear market until the last week of August and have all rallied furiously since then.
What the heck happened the last week of August?
"Simple. The Chinese stock market, which had been in free-fall since June — dropping from the 5,100 level to just below 3,000 — finally stopped going down," the "Mad Money" host said.
Since the bottom in the Shanghai stock exchange on Aug. 26, the Chinese market has rallied hard. It is up more than 15 percent and has taken U.S. industrial and oil stocks with it.
"The systematic risk from either China or Glencore has diminished. It's pretty amazing that this one index could have that kind of power, but to deny its reach seems dead wrong," Cramer said. (Tweet This)

Another group that has made quite a comeback are the cruise line stocks. After a rough start to the year Royal Caribbean, the No. 2 largest player in the space, has led the way up 45 percent from its lows in the spring.
Cramer thinks that some of the strength is correlated to the low cost of fuel, which could mean these companies are saving a boat load on the bottom line.
Royal Caribbean reported an incredible quarter a week-and-a-half ago and proved that cheap fuel wasn't the only thing bolstering the stock. Its net yield — an important key metric in the industry that measures how much money the company makes from its passengers — increased by 5.1 percent on a constant currency basis.
Additionally, the company raised its full year earnings guidance and announced a $500 million buyback, prompting the stock to shoot up 3 percent on the news. To find out more about what the future could hold for Royal Caribbean, Cramer spoke with Chairman and CEO Richard Fain.
"I think that the change is two things. First of all, we have offered so much more…The other thing that has happened is that people have begun to realize all that we offer. You can go new places and you don't have to pack and unpack. So, we have had an explosion in the attractiveness," Fain said.
In the Lightning Round, Cramer gave his take on a few caller-favorite stocks:
Rite Aid: "I want to own Rite Aid. I'm not going to tell you to buy it right here because I've been telling people to buy it for a very long time. But I do think that some deal gets done. If not by Walgreen than by somebody else."
AbbVie Inc: "There was some Gilead news today that's not as good for its Hep C drug, which means that AbbVie is going to go up. AbbVie reported a great quarter."
