Cramer Remix: Warning about Friday’s rally

Cramer's warning about Friday's rally   

Be careful, Cramerica.

Jim Cramer warned that even though the Dow, NASDAQ and S&P climbed higher on Friday, we are not in the clear.

"You need to remember, their weakness is not our weakness, and their strength is not our strength," the "Mad Money" host said.

Yes, it is wonderful that the Chinese lowered interest rates and there were promises coming from the European Central Bank President Mario Draghi.

"But until we actually see the gigantic infrastructure of jobs in the decrepit sewers and polluted wastelands that engulf China, until we see that the Germans spend $500 billion to stimulate their economy—something that Angela Merkel's government appears unwilling to do—you need to be careful," Cramer warned.

Cramer also took a moment to pay tribute to the passing of his father, Ken Cramer, a.k.a. Pop, in a heartfelt tribute to his passing. Jim said that Pop loved seven things: his business, the stock market, his independence, his workouts, his country, the Eagles and his family.

Most of all, Pop loved Jim and his sister, Nan, and his grandkids. The family surrounded Pop as he passed away, in the early hours of Nov. 20. Pop was 92.

Cramer shared that as he and his sister sat next to Pop in the hospital, his father spoke of the Packers' recent beat-down of the Eagles and Jeb Bush's potential in politics. He even gave Cramer a few business ideas.

"He said he was glad he had his pals around him, and he loved us. We said the same. It was the last thing we said to one another, then, 'See you in the mernin,' which was how he always pronounced it. We didn't. We went to sleep and when we awoke he was no longer alive. Our last day together was our best one. That's how it should be. Strong to the end. So long, Pop. We love you."

Heading into the holidays, Cramer likes to stop and take the temperature of the American consumer. What better way to do that than to think about yachts, snowmobiles and motorcycles?

So what the heck do these three things have in common? They're all expensive, and they're probably the things you least need on this planet.

"These are essentially playthings for the rich, as well as extreme enthusiasts who are happy to shell out all their savings if it means they can have an amazing bike or terrific boat," Cramer said.

Three discretionary stocks that are on fire right now will tell us exactly how to gauge the holidays: Harley-Davidson, maker of motorcycles; Brunswick Corp., top manufacturer of yachts; and Polaris Industries, which is all about snowmobiles and all-terrain vehicles.

These stocks also tell a powerful story: This holiday season is going to be fabulous for gift giving.

One stock that has also been climbing the charts recently, is Zoetis. It is the No. 1 animal health business on Earth that was spun-off by Pfizer last year. After trading sideways for a long time, the stock has finally caught fire, rallying 36 percent since June.

The company is also showing some love to shareholders, announcing a $500 million buyback plan. Cramer sat down with the CEO of Zoetis, Juan Alaix, to find out if this stock will keep on roaring.

Activist Bill Ackman recently took an 8.5 percent stake in the company. What could be up Ackman's sleeve?

"I think he understood that the animal health industry is a very attractive investment opportunity," Alaix said. "Also that Zoetis is a leader in this industry and we have the characteristics and business model, we have the culture, we have the financial strength to capture the opportunities that animal health will bring in the future."

Likewise, one company that has the edge above the earnings, and is willing to go where no one else will, is Exact Sciences. They are actually taking excrement and turning it into earnings.

Many may think it is waste, but not Exact Sciences. They have created a way to use your own excrement as a way to stop colon cancer. This development is a game-changer and can detect colon cancer with over 90 percent sensitivity.

Since this development, this stock has taken off, doubling since the beginning of the year and is up 108 percent since January. Cramer spoke with the CEO of Exact Sciences, Kevin Conroy, to find out if the word on this new development could spread further and give the stock more room to run.

"People are starting to get to know about this, in part because the disease is such a big problem … That really speaks to what we have been working on for so long, is to have an impact on people. We have 120 professionals out there right now talking to physicians and spreading the word, and it's starting to have an impact," Conroy said.

In the Lightning Round, Cramer continued his cautious warnings on caller favorite stocks.

Ford Motors: "These are plays on international growth, and we don't have any worldwide growth. That's the problem. I think Ford is cheap, I think GM is cheap and my Charitable Trust owns GM. We are suffering, but every dog has its day and I think it's GM's day."

Pembina Pipeline: "No, I know them. This Kinder Morgan deal is about to close. KMI, that's where you want to be."
