While most sectors trade in lockstep, there are still some areas where individual stock picking matters. Some succeed, and others fail on their own merit.
One of those groups is the airlines, and with a hideous decline in United Continental on Thursday, Cramer still considers Southwest Airlines to be among the best in the group.
Southwest reported a strong quarter on Wednesday, including $1.2 billion in free cash flow. While some of the strength stemmed from lower jet fuel prices, some comes from new capacity, which could be worrisome as, historically, capacity can set off a price war between airlines.
Cramer spoke with Southwest's CEO Gary Kelly, a 29-year veteran of the company. Since its inception, Southwest has never laid off a single employee.
"I give all the credit to our people. I think they are the best in the business. We have very low cost, we offer great service, it's just a powerhouse combination," Kelly said.
Cramer is always on the lookout for private companies with game-changing technology. Highfive is a business that has simplified the conference room by dominating the video conference space. Its technology provides easy screen sharing and all-in-one video and audio that can be controlled on devices, laptops, tablets and phones.
Highfive has significantly expanded its customer-base growth since the company was founded some 18 months ago. Cramer spoke with Highfive's founder and CEO, who explained the reason behind the growing popularity of video conferencing.
"We are seeing some really big secular trends happening that are causing people to be more comfortable with video. The new workforce is all at an age now that they grew up with video," Sinha said.
In the Lightning Round, Cramer gave his take on a few caller-favorite stocks:
B&G Foods: "No, I used to be higher on it but not anymore. Not when you've got stuff that I see flying, like a Kellogg, like a Smucker. No, we are not going to go there. B&G was OK, I got better places now."
Cameco Corporation: "Periodically people tell me I've got to take another look at it. I have looked at it and looked at it, but my conclusion is don't buy."
