The stock market's leaders have no followers, Jim Cramer told his Mad Money viewers Tuesday, and without more followers, it will be very hard for stocks to continue to rally.

Among the biggest winners today were the tech stocks, Cramer said, with names like Amazon (AMZN) and Netflix (NFLX) extending their gains. Coupa Software (COUP) also surprised the markets with strong earnings, news that sent shares soaring 8.7% by the close.

Retail was also on fire in today's session, with Macy's (M) up 7.9%, Kohl's Stores (KSS) gaining 4.7% and Burlington Stores (BURL) tacking on another 2.5% to extend its gains from $90 to $155 a share.

But beyond these two groups, Cramer said, there wasn't much else that was working and that's a troublesome sign.

The financials should be big winners with strong employment, but investors appear to be waiting for even higher interest rates. Cramer said it's ridiculous that JPMorgan Chase (JPM) trades for just 11 times earnings and Goldman Sachs (GS) for just 9.5 times. The drug stocks, health insurers, the transports and even the consumer staple stocks are also sitting on the sidelines.

Without more names participating in this rally, it won't be a rally for long, Cramer concluded.

Executive Decision: Palo Alto Networks

In his first "Executive Decision" segment, Cramer spoke with Mark McLaughlin, the outgoing chairman and CEO of Palo Alto Networks (PANW) , as well as with Nikesh Arora, the company's incoming CEO.

McLaughlin said that Palo Alto continues to do well, with 30% revenue growth, but as they look to what's next, they will need experience in the cloud, analytics, machine learning and predictive security -- all things that are strengths for Arora.

Arora, formerly of Alphabet (GOOGL) , said that we're still early in the cloud revolution and the need to secure our digital future was too exciting an opportunity for him to pass up. Palo Alto is a leader in the space, he said, and that will only continue in the future.

McLaughlin noted that Palo Alto takes customers from the competition every quarter and the win rates are always high. He will be staying on with the company as a vice-chairman. 

From Seeds to Birds 

In his "No-Huddle Offense" segment, Cramer opined on the upcoming change to the S&P 500 and its generational significance. Seed-maker Monsanto (MON) will soon be leaving the S&P, replaced by social media giant Twitter (TWTR) .

Cramer said for the older generation, Monsanto was a symbol of better living through technology. But today, the genetically altered foods run smack in the face of the natural and organic trend.

Twitter on the other hand, is viewed as Monsanto used to be: a tool for the future. The stock has had an amazing run, up 118% over the past year, and with presidential tweets happening daily, it's hard to imagine a time when we lived without it.

Executive Decision: Wyndham Destinations 

In his second "Executive Decision" segment, Cramer sat down with Michael Brown, CEO of Wyndham Destinations (WYND) , the time-share arm of Wyndham Worldwide, which recently spun off Wyndham Hotels (WH) , a segment that was featured on Monday's Mad Money.

Brown said that Wyndham is now a pure-play on vacation time-share destinations, an industry that's as strong as ever. Today's vacationers want space, amenities and consistency, he said, and Wyndham caters to the everyday traveler, which is the market's biggest segment.

In addition to allowing customers to lock in future vacations at today's rates, Wyhdham also sees big opportunities in the secondary markets when timeshare owners decide to make their exits.

When asked about their balance sheet, Brown said his company will be making modest debt repayments, but also returning cash to shareholders via a $1.64 a share dividend and through stock buyback programs.

Cramer said investors looking for a company that's unlocking value should consider Wyndham Destinations.

Executive Decision: Medtronic

In his final "Executive Decision" segment, Cramer sat down with Omar Ishrak, chairman and CEO of Medtronic (MDT) , the medical device maker with a history of innovation and disruption.

Ishrak said that Medtronic was founded in 1950 with the original pacemaker, a Walkman-sized device that was worn on your belt. Today, the company is debuting the Micra pacemaker, a device the size of a bullet, which can be inserted directly in the heart via catheter. The battery on the device lasts 10 years, he said, and the patient can leave the hospital immediately after the procedure.

Medtronic is using similar technology to stimulate the spine and manage chronic pain. Ishrak said this technology is in the early stages of deployment and has a bright future.

Finally, Ishrak spoke about their diabetes management systems, which include implanted insulin pumps and monitors that can act was an artificial pancreas to automate management of the disease. Medtronic currently has 70,000 patients, Ishrak noted, and this is among their fastest growing products.

Cramer was bearish on The Carlyle Group (CG) , Corning (GLW) , Banco Santander (SAN) , US Bancorp (USB) and J. Jill (JILL) .
