Before buying a stock, investors need to ask themselves one more important question, Jim Cramer told his Mad Money viewers Monday. They need to ask whether the company could come under fire from Amazon (AMZN - Get Report) . Cramer said Amazon's ability to disrupt commerce is unlike that of any other company, and Amazon it takes aim at a sector, those stocks will never trade the same again.

Today's rumors that Amazon may consider offering its own streaming music service sent shares of Spotify (SPOT - Get Report) down 4.4%, despite the fact Spotify has been a market leader with a beloved product that was thought to protect it from newcomers. But with hundreds of millions of devices, Amazon is a serious threat, Cramer said, and Spotify may never fully emerge from under the shadow of Amazon.

Spotify is not alone. Drugstores like Walgreens Boots Alliance (WBA - Get Report) have seen their gross margins crimped by Amazon, as have book sellers, music retailers and countless others in their path.

That's not to say Amazon cannot be beaten, however. Cramer said Best Buy (BBY - Get Report) has doubled down on services and has survived, as have the auto parts stores, the dollar stores and Home Depot (HD - Get Report) and Lowes (LOW - Get Report) .

But beyond these select groups, Amazon is seemingly everywhere, from retail to cloud computing to advertising -- which is why its presence needs to be a factor in all your investing decisions.

Executive Decision: ConAgra

For his "Executive Decision" segment, Cramer spoke with Sean Connolly, president and CEO of ConAgra Brands (CAG - Get Report) , a stock that's up 41% for the year and over 50% from its December lows.

Connolly said no brand is exempt from challenges, and that includes the brands ConAgra acquired when it purchased Pinnacle Foods. He said brands such as Bird's Eye, for example, have huge potential, but they need meaningful innovation in order to stay relevant to today's younger consumers. While may pan frozen vegetables as the opposite of healthy and organic, they are actually the perfect food for millennials on the go and those with limited cooking skills.

ConAgra embraces life-long learning, Connolly added. If they make investments that don't resonate with consumers, they're quick to try something new. That's why two-thirds of their marketing budget is now spent on digital advertising and personalization to reach today's consumers.

Cramer remained bullish on ConAgra.

Taking a Swing at Golf Stocks 

Now that Tiger Woods has made a big comeback by winning his 15th career major at the Masters over the weekend, is it time to take a second look at the golf stocks? Cramer revisited two favorites, Callaway Golf (ELY - Get Report) and Acushnet Holdings (GOLF - Get Report) , to find out.

Cramer said with Woods back in the game, media viewership for golf has been on the rise, as is interest in off-course golf activities such as the privately held Top Golf, which turns the driving range into a modern, high-tech experience. But there remains only two publicly traded options: Callaway and Acushnet.

When it comes to Callaway, makers of Titleist golf balls as well as footwear and apparel, Cramer said this stock continues to be a bargain, trading at just 15 times earnings. Acushnet is also attractive, as this company continues to have higher gross margins as it takes market share and capitalizes on cutting-edge trends like personalization. Acushnet also trades at less than 15 times earnings.

Of the two, Cramer gave the edge to Acushnet, but said Callaway is a beaten-down stock that could also be ready to roar higher. It just remains more risky than Acushnet. 

Executive Decision: Chevron

In his second "Executive Decision" segment, Cramer also sat down with Mike Wirth, chairman and CEO of Chevron (CVX - Get Report) , to discuss his company's recently announced merger with Anadarko Petroleum (APC - Get Report) .

Wirth called the deal with Anadarko a "grand slam," as both their combined assets are a strategic fit in the Permian Basin, deep water and also in Africa. He said Anadarko had a good portfolio, good assets, good people and good management.

When asked about those assets in the Permian Basin, Wirth said every year, the drilling technology gets better and better, which leaves decades of oil production still to go in the Permian. He was also excited for Anadarko's African projects, which will continue move forward.

Finally, when asked about refining here in America, Wirth said we'll continue to see more and more U.S. light sweet oil get exported to the rest of the world, as much of our domestic refining capacity is still not able to process lighter grades of oil. 

Why the Fed Shouldn't Hike 

In his "No-Huddle Offense" segment, Cramer explained that our economy is not an either-or situation. It's not either too hot or too cold. There is a middle ground where things can be going well and the Federal Reserve doesn't need to raise interest rates.

Cramer told viewers not to fret over the inverted yield curve, as that was caused by the Fed raising rates in December when it didn't need to. In reality, much of the economy's gains are being offset by technology and digitization making companies more efficient and therefore in need of fewer workers. Everything from retail to the home builders is affected by technology, Cramer said, and that's why the economy is in the perfect spot for continued growth.

Lightning Round

In the Lightning Round, Cramer was bullish on 3Pea International (TPNL) , Oracle (ORCL - Get Report) , Walmart (WMT - Get Report) , Toll Brothers (TOL - Get Report) , DR Horton (DHI - Get Report) , Lennar (LEN - Get Report) , Norwegian Cruise Line Holdings  (NCLH - Get Report) , Bluebird Bio (BLUE - Get Report) , Broadcom (AVGO - Get Report) and Cadence Systems (CDNS - Get Report) .

Cramer was bearish on Nektar Therapeutics (NKTR - Get Report) .
