It's hard to be a bricks-and-mortar retailer when most of the things you sell can be bought easier and quicker through Amazon (AMZN - Get Report) . That was the takeaway from the 11% plunge in Dick's Sporting Goods (DKS - Get Report) , Jim Cramer told his Mad Money viewers Tuesday, and it might be just the beginning.

He said all investors need to dig in, and do their homework to fully understand what's happening with stocks like Dick's, and Boeing (BA - Get Report) , shares of which hit a five-week low Tuesday as the plane maker stood by its 737 MAX 8 jet in the face of groundings of the flagship aircraft.

On the surface, Cramer said Dick's, what he called a "best in the business" sporting goods retailer, delivered an OK quarter, but with murky guidance. But the kiss of death, as far as Wall Street is concerned, was when Dick's admitted it will be investing in its online operations to keep up with Amazon. Not only does the company need to invest in itself, it's also increasing its spending with Facebook (FB - Get Report) and Alphabet (GOOGL - Get Report) to drive more traffic to its website.

Any time a company needs to invest, it hurts gross margins, Cramer reminded viewers. Add to that rising freight costs and Cramer concluded he would steer clear of Dick's Sporting Goods for the foreseeable future.

On a positive note however, Cramer added that Nike (NKE - Get Report) remains a buy, as does Facebook and Google, both of which are growing in importance in the race against Amazon.

Executive Decision: VMWare

For his "Executive Decision" segment, Cramer spoke with Sanjay Poonen, COO of VMWare (VMW - Get Report) , the cloud software provider that just posted a solid quarter that included 16% revenue growth.

Poonen explained that VMWare is helping to usher in the next generation of data centers, ones that are both automated and intelligent. His company works closely with Amazon, the leader in the cloud space, and that partnership continues to go well.

VMWare is also actively involved in the upcoming 5G wireless build out, providing telcos with cloud software to help their networks and customers transition to this next generation of wireless technology. This transition will take several years, Poonen said, and will be a huge opportunity for VMware.

Finally, Poonen talked about VMWare's efforts in the area of diversity and inclusion. He said VMWare is actively creating positive role models and is making strides to defy industry averages to include more women throughout their organization.

Off the Charts

In the "Off The Charts" segment, Cramer checked in with colleague Carley Garner over the chart direction of the U.S. dollar, which could impact the earnings of everything from Procter & Gamble (PG - Get Report) to Apple (AAPL - Get Report) .

Garner looked at a monthly chart of the U.S. dollar versus the S&P 500, noting that currently, the dollar index is at unsustainable levels and is due for a pullback. She also compared the seasonal patterns for the dollar, which typically peaks in March and pulls back through mid-April. Garner's case was further bolstered by the Williams Oscillator, which showed the dollar in overbought territory.

Cramer said when it comes to currency, the dollar is not alone. That's why it's also significant that the euro saw a key reversal on Friday, one which could weaken the dollar.

Add it all up and there's a strong case for a weakening dollar, which would be great news for so many stocks.

Executive Decision: Coupa Software

In his second "Executive Decision" segment, Cramer also sat down with Rob Bernshteyn, CEO of Coupa Software (COUP - Get Report) , another cloud software provider. Coupa just reported a quarter with 45% subscriber growth, yet its shares plunged 3.2%.

Bernshteyn said the growth drivers at Coupa haven't changed in the past decade. They help customers not only save money by optimizing their spending, but also aid in providing visibility, compliance and a host of other benefits. They have year to crack even 10% of the Fortune 1000, but are still landing big deals every quarter.

When asked about who their customers are, Bernshteyn listed data center companies who are saving on air filters, manufacturers who save on freights costs, and others that have saved over $10 million on refrigerators, all with Coupa's platform.

Bernshteyn added that Coupa takes a measured approach to growth and ensures that every customer gets up and running and is successfully. That means every customer is poised to grow in the future, adding to their growth. 

Outlook for Semiconductors

In his "No-Huddle Offense" segment, Cramer reminded viewers that some sectors punch above their weight in the stock market, and the semiconductors are one of those sectors. That's because chips go into just about everything we buy, making them a great gauge for the global economy.

Cramer said it's been a tough time for the semiconductors as end markets began to decline late last year. It was led by Skyworks Solutions (SWKS - Get Report) , which saw weakness in cell phones. Broadcom (AVGO - Get Report) soon followed after its merger was denied. Semi equipment maker Lam Research (LRCX - Get Report) confirmed the slowdown weeks later, as Micron Technologies (MU - Get Report) , Advanced Micro Devices (AMD - Get Report) and market darling Nvidia (NVDA - Get Report) followed.

All of these names have been weak for months, Cramer said, until they weren't. Almost overnight it seems there's once again hope in this group, hope that Apple may start buying more chips and that auto sales might be rising, along with gaming, the cloud and other sectors. Cramer said he thinks all of these stocks could be bought into weakness.
