Buying a stock requires multiple leaps of faith, Jim Cramer told his Mad Money viewers Wednesday. Investors are betting on the economy, the company and its management team, just to name a few. But Cramer said in his experience, what matters most is the brand and the company's CEO.

Nowhere was that more evident than with Walt Disney Co.  (DIS) - Get Report  on Wednesday, after the company announced it had already racked up over 10 million subscribers to its Disney+ streaming service, despite having a few launch-day hiccups. Cramer said Disney is a tremendous brand and its CEO, Bob Iger, is nothing if not magical himself.

Disney+ was never a gamble, Cramer said, as Iger knew it was more risky not to leverage the company's huge and growing content library. Iger saw the potential of streaming years ago when he purchased the streaming media arm of Major League Baseball, which is today at the heart of the Disney+ service. And Iger knew that Disney+ wasn't just for kids. Most of the service's rave reviews are coming from adults revisiting their childhood favorites.

That's why you never bet against a great brand and CEO, Cramer said. The same is true of Apple (AAPL) - Get Report under Tim Cook and of Abbott Labs (ABT) - Get Report under the outgoing Miles White. These are companies you can trust, Cramer concluded, and they should be bought on any weakness.

Executive Decision: Dexcom

For his "Executive Decision" segment, Cramer welcomed Kevin Sayer, CEO of Dexcom (DXCM) - Get Report , back to the show. The glucose monitoring company posted a monster 65-cents-a-share earnings beat that sent shares soaring 27% last week and they rang the opening bell Wednesday in honor of the company's 20th anniversary.

Sayer started off by saying that Dexcom solves a serious problem for patients with diabetes: monitoring their glucose levels with technology instead of finger pricks. This new technology is making diabetes management more accessible.

Sayer said there's a lot to be learned from the data that Dexcom's monitors collect. Patients can see their data to spot patterns, trends, and identify certain foods that cause them problems. But they can also share their data with their doctors and loved ones. Data sharing isn't just for parents and children, Sayer added, everyone can benefit.

When asked about their latest system, Sayer said their G6 monitors are more accurate and now don't even require a finger prick for calibration. The units are easily pair with a patient's phone and their software does the rest.

Turning to the topic of competition, Sayer said there's room for everyone in this growing market, but Dexcom has always had the superior technology. 

Executive Decision: Hersha Hospitality

In his second "Executive Decision" segment, Cramer sat down with Jay Shah, CEO of Hersha Hospitality Trust (HT) - Get Report , the hospitality REIT with 48 properties and an 8% yield.

Shah said that Hersha, which operates mainly in the New York, Washington, D.C., Philadelphia, Boston and Miami markets, will be seeing some tailwinds in 2020. He said their two properties in Miami that were closed from hurricane Irma have now reopened and Miami is forecast to be the top growth market in 2020. Additionally, Hersha has sold its slower-growing properties and is adding new, higher-growth properties in their place.

When asked about the competition from Airbnb, Shah explained that Airbnb did dilute many markets with excess inventory. However, as municipalities are cracking down on illegal rooms with additional regulations, some markets are seeing Airbnb rentals fall by up to 50%. Meanwhile in the New York market, demand overall is flattening, Shah said, making Hersha's properties more attractive.

Shares of Hersha are down 21% for the year.

No Pain, No Gains? 

Staying in shape isn't going out of style anytime soon for the selfie generation, Cramer told viewers. So, is it time to get back into fitness stocks like Planet Fitness (PLNT) - Get Report and newcomer Peloton (PTON) - Get Report after a rocky summer?

Shares of Planet Fitness dropped 31% from their highs earlier this year as it fell out of favor and investors took issue with the company's 8.8% same-store sales growth in August when analyst were expecting 9%. But Cramer said Planet Fitness remains a well-run company that was able to beat estimates when it last reported and is now seeing shares recover from their lows.

Peloton had a rocky IPO in September, debuting at the wrong time and immediately breaking its IPO price. While management said the company could cut spending and become profitable at any time, Cramer said the reality is Peloton is not a company that will have earnings anytime soon.

Because these companies are so different, Cramer said, he wouldn't be a buyer of Peloton until the lockup period expires in a few months. Planet Fitness, however, should never have fallen as far as it did and is now a buy.

5G Is More Than Cellphone Technology 

In his "No-Huddle Offense" segment, Cramer said the 5G wireless train is leaving the station and the time to get on board is now. 5G wireless networks aren't just the next evolution of wireless, Cramer said, they're a revolution that will fuel a lot more than just cell phones.

According to industry experts, the 5G cycle will be bigger than both 3G and 4G, with over five billion wireless subscribers needing to upgrade. But beyond smart phones, 5G will power all-new technologies like the connected car and a host of industrial applications. That means everyone from General Motors (GM) - Get Report to General Electric (GE) - Get Report , Honeywell (HON) - Get Report and Rockwell Automation (ROK) - Get Report will be lining up to buy these very important semiconductors.

Lightning Round

In the Lightning Round, Cramer was bullish on Coca-Cola (KO) - Get Report and Danaher (DHR) - Get Report .

Cramer was bearish on Mettler-Toledo International (MTD) - Get Report and Icahn Enterprises (IEP) - Get Report .
