The gloom in the stock market is palpable, Jim Cramer told his Mad Money viewers Monday. So palpable in fact, the pessimism can sometimes be overwhelming. That's why Cramer created a fictitious "Gloom Index" to let investors know which stocks will be heading lower any time there's talk of tariffs or trade.

Cramer gave his Gloom Index the aptly-named, if fake, ticker: GLUM. He said if it was real, when investors felt glum, they could simply sell some GLUM.

The index included Caterpillar (CAT) , Boeing (BA) and 3M (MMM) , three stocks investors see as at the epicenter of trade wars. It also included General Electric (GE) and Johnson & Johnson (JNJ) , two companies investors see as total messes.

Every good index needs some financials, so Cramer added Citigroup (C) and Goldman Sachs (GS) , two stocks which can't seem to do anything right.

Rounding out the index was Lennar (LEN) , which investors fear can't escape rising interest rates and lumber prices; Walmart (WMT) , which will supposedly be afflicted by a slowing global economy; and Ford (F) , the world's least interesting automaker.

But while the market is selling GLUM seemingly every day, Cramer said he'd be buying these stocks into any weakness, as the doom and gloom has simply gotten out of hand. He was also a fan of tech, with Advanced Micro Devices (AMD) and Dropbox (DBX) just two of the standout names in today's  otherwise glum session.

Executive Decision: MedMen Enterprises

In his "Executive Decision" segment, Cramer sat down with Adam Bierman, co-founder and CEO of MedMen Enterprises, a Canadian-based retailer of cannabis that is among the first to be listed on the Canadian stock exchange.

Bierman said the legalization of marijuana has been slow to evolve, but he thinks the momentum is building. MedMen is excited to be in the four largest marijuana markets, including California, New York, Nevada and Florida. In those markets, there are many barriers to enter, Bierman explained, including supply constraints and tough zoning requirements.

As marijuana becomes more mainstream, MedMen stores will be there to serve, Beirman added, with over 1,000 SKUs offering just about everything customers could ask for.

When ask why MedMen is not listed for trading here in the U.S., Beirman said as soon as U.S. laws allow, they plan on being listed.

Cramer says when you spend a whole day interviewing and listening to more than a dozen people, as he did recently at TheDeal's Corporate Governance conference, you can come back with a gazillion takeaways. Check out his Top Takeaways over on Real Money.

Enterprise Software 

The enterprise software sector has been hot this year, with many recent sought-after IPOs. Is it now time to ring the register and take profits, or does this group have more room to run?

Cramer looked into the giant moves at Carbon Black (CBLK) , Docusign (DOCU) , Pivotal Software (PVTL) , Zscaler (ZS) and Zuora (ZUO) , the latter of which was featured on Mad Money last week. All of these stocks soared at their IPOs and never looked back. The problem? None of these companies have yet to turn a profit and their valuations are now in the stratosphere.

Cramer said this group has several things pulling in their favor: They're in secular growth markets, there's a scarcity of stocks to choose from and the urge to merge makes them likely takeover targets. But at these valuations, Cramer said,  investors need to know what they own, take some profits and not be greedy. He's still a fan of Zoura, along with Coupa Software (COUP) and Okta (OKTA) , but he simply cannot like them as much as when their stocks were much, much lower.

Trading Tensions 

Love him or hate him, President Trump is not the cause of a global slowdown, Cramer told viewers. In fact, it's likely there isn't a slowdown at all.

Despite the numerous headlines you may be reading, Trump's tariffs on steel and aluminum have not sent the entire planet's economy into a tailspin. Cramer said while it's true that an escalating trade war could eventually spin out of control, that hasn't happened yet, nor is it likely to.

Cramer said he's been hard pressed to find any CEO come out and blame tariffs for a slowdown in their business. He posited that it's far more likely that any weakness we're seeing have been caused by the 50% rise in oil prices over the past 12 months, as oil is used as feed or fuel in countless industries, from chemicals to cruise lines.

Correlation is not causation, Cramer concluded, despite what you may read online.

Off the Tape

In his "Off The Tape" segment, Cramer once again sat down with Noah Glass, founder and CEO of the privately-held Olo, the digital ordering system provider for restaurants.

Glass noted when he last appeared on Mad Money in October, 2015, Olo was supporting 12,000 locations on its platform. Today, that number exceeds 48,000. That's because it's expected that $200 billion worth of orders will be shifting from in-store to online in the coming years.

As more and more customers get comfortable with online ordering, more and more people are giving it a try and loving it, Glass said, and that includes both ordering and delivery.

That's why Olo has created Dispatch, an application that coordinates order preparation with delivery, pairing the right driver with the right restaurant. On average, Glass said Dispatch can deliver an order in just 12 minutes, partially because it polls every delivery service that serves that restaurant and ensures that the driver and your food are ready at the same time.

When asked about becoming a public company, Glass said there are no plans for an IPO at the current time.

Lightning Round

In the Lightning Round, Cramer was bullish on Praxair (PX) , Intrexon (XON) , Verizon (VZ) , AT&T (T) , ICU Medical (ICUI) , Baidu.com (BIDU) , Baozun (BZUN) and JD.com (JD) .

Cramer was bearish on CenturyLink (CTL) and Momo (MOMO) .
