Cramer Remix: Four stocks you must watch

When Jim Cramer created the acronym FANG — which stands for Facebook, Amazon, Netflix and Google — the stock he was most worried about was Facebook. But guess what? FANG is alive and well, especially Facebook.

"FANG is flying because these stocks represent the best we have in a market that has turned very mixed," the "Mad Money" host said.(Tweet This)

The reason Cramer was most concerned about Facebook was not because of its high price of 30 times 2017 earnings; it's because he wanted to be sure that its investment spending was paying off.

Cramer doubted Facebook CEO Mark Zuckerberg, who Cramer thought overpaid with the $19 billion price tag for WhatsApp. Now it has 900 million users. Whoops! Cramer also doubted the $2 billion purchase of Oculus, though it is now clear that Zuckerberg intends to dominate the gaming category with 250 million users and intense growth.

"Call me a moron, but I was simply taking my cue from the headline writers and the bears, never a wise sign," Cramer said.

Facebook is just one part of the unstoppable group of FANG, with Netflix, Amazon and Alphabet all crushing the competition. And what unites them all? They are all companies at the edge of everyone's fingertips. Everyone likes entertainment, and everyone likes a bargain. And that's what they bring.

After reporting an ugly third quarter on Wednesday, Cramer wasn't sure what to say about Whole Foods.

"In an industry that lives by same-store sales, one where you can actually measure how stores do year over year, Whole Foods has become King Midas in reverse," the "Mad Money" host said. (Tweet This)

Comparable stores dropped 0.2 percent in the third quarter, fell an additional 2.1 percent in the month of October. Additionally, gross margins declined 96 basis points because of the cost of goods sold. Sales declined and expenses went up.

Whole Foods dominates its industry in cash generation, with $970 of sales per square foot and $132 million in total for the last quarter. It responded to declining sales and increasing expenses by taking that cash and using it to buy back $1 billion in stock, and then borrowed up to $1 billion more to repurchase even more shares.

"To which I say, do you really think buying back tons of stock is a great use of capital when you have under-invested and need to get back to basics?" Cramer said.

One group of stocks that have been roaring recently are the industrials, including PPG Industries, the specialty chemical maker that produces proprietary paints and coatings.

After 34 years with the company, Michael McGarry just took over as CEO of PPG, after long-time CEO Chuck Bunch stepped down. And if any investors were worried that the company would miss a step during the transition, McGarry put those fears to rest when PPG reported a solid quarter on October 15.

Cramer had the opportunity to speak with McGarry, who commented on the bullish outlook for construction in the U.S.

"We see a solid continued construction recovery. I think this is very beneficial that it's gradual; it's not a huge spike up. Our glass business continues to improve quarter over quarter and I think this is good for the economy," McGarry said.

FireEye's stock was absolutely obliterated on Thursday, dropping more than 22 percent, after reporting a no-so-hot quarter. The stunning decline prompted Cramer to question the cybersecurity space, and where the future of FireEye could be headed.

FireEye has a high-quality, machine-based cybersecurity platform that provides clients with real-time protection from some of the most sophisticated forms of cyber attack. It is also widely regarded as the best forensics specialist in the business; the company many businesses call when they have been hacked and want to figure out what happened.

It reported on Thursday that it delivered a larger than expected earnings loss on weaker than anticipated sales, even while it managed to grow 45 percent. What really frightened investors was the fact management slashed full-year sales, earnings and billing guidance. It provided a fourth-quarter forecast that was significantly below what analysts were looking for.

To learn more, Cramer spoke with FireEye's Chairman and CEO David DeWalt.

"This company has grown from a sub-$50 million company to nearly a $1 billion company in less than 12 quarters. We were the beneficiary at times of a surge or spike that is happening in cybersecurity," DeWalt said.

In the Lightning Round, Cramer gave his take on a few caller favorite stocks:

Alcoa: "Remember they are splitting in two. The stock seems to have settled at $9. I like the action in the stock and I'm tired of hearing that aluminum is being dumped by China because it's not anymore, and there is a deficit coming in aluminum."

Iridium Communications: "Many years ago I recommended the stock, and it's disheartening to hit the stock up and see it's exactly where it is; which is pretty much the same place. I just think that this is a tired company. It needs to do something to boost its growth, and that is what we want. Growth."
