On Wednesday's episode of "Mad Money," Jim Cramer told his viewers that he's tired of hearing about drinking the so-called Kool-Aid. Yes, the market continues to ramp higher, hitting new highs. But as he explained Tuesday, the economy is justifying the move.

Need more proof? Just look at the Dow Transports. 

The segment continues to roar, as airline, railroad, and trucking stocks move higher. Would commerce and traveling be driving up commerce if the economy were weakening? Or would Warren Buffett -- arguably the world's most noteworthy investor -- have upped his airline holdings?

Cramer also pointed out that another important investor, activist Nelson Peltz, made a huge investment in Procter & Gamble (PG) . 

Sure, some of the rally is being driven by animal spirits and the anticipation of tax reform from President Trump. But a large part of this rally is being driven by earnings, Cramer stressed. 

He argued that instead of the indices being led higher by a handful of REITs, utility and biotech stocks, and FANG, we've got a broad base of rallying. Investors can see it in industrial, health care, technology and financial stocks.

Financials, and in particular, banks, can increase their profitability when interest rates go higher.

And when rates go higher because of a stronger economy, that's a good thing. The banks are inspired to increase commercial lending and fuel even more economic expansion, Cramer reasoned.

Best of all? Bank stocks still trade with a below-market valuation, he said. 

Here's the bottom line: While some people may think the market is spiraling out of control to the upside, they need to realize there are several classic signs presenting themselves that the market may in fact know what it's doing and that this rally isn't out of control. 

Meanwhile, on Real Money, Cramer explains some tried-and-true indicators that show what's really going on with the market. Check out Cramer's strategies with a free trial subscription to Real Money.

Off the Charts

In the show's "Off the Charts" segment, Cramer took a closer look at copper. The metal is known as "Dr. Copper" on Wall Street because of its correlation with the global economy. So Cramer wanted to size up this helpful economic barometer. 

When copper is in high demand, it generally means the economy is doing well because so many products require the commodity, likes cars, houses and factories. If copper's being bought, there's usually a reason for it. 

According to the work from Real Money contributor Ed Ponsi, copper's breakout last week appears to be the real deal. Known as an ascending triangle, the commodity completed the bullish setup after it broke out to the upside and looks like it could rally from $2.80 per pound to $3. 

It helped that the strong rally was done on heavy volume as well. And it was more than a coincidence that China recently reported a slew of strong economic results. The country buys more than 50% of the world's copper each year, and so when its economy heats up, copper will feel the spark. 

Copper also tends to have a high correlation with the stock market. Cramer pointed out that the metal's rally proceeded the stock rally in November 2017, as well as two months before the 2009 low. 

However, Cramer also pointed out that a shortening in supply could be driving prices up too, which would throw some cold water on the bullish case. So while investors shouldn't go all-in just because Dr. Copper is rallying, they should also pay attention to the metal's recent move.

Procter & Gamble

What makes Procter & Gamble such a great consumer products company? Cramer pointed out the company's superior products, near-impervious business model regardless of economic times, and its capital return plans through its buyback and dividend. 

So why does this stock trade with an above-market multiple, while a company like Apple (AAPL) sells at just 15 times earnings?

Cramer pointed out that Apple has a fabulous buyback and rapidly rising dividend, also creates market-leading products and has a business that can weather strong economic storms as well. Not to mention, its services revenue business has been on fire and provides the company with a stable, rising stream of income. 

Perhaps if different analysts took a look at this stock -- perhaps the people that cover Newell Brands (NWL) and Clorox (CLX)  -- rather than those who cover social, cloud and mobile companies, they would appreciate the company more. 

Or what about Facebook (FB) and Alphabet (GOOGL)  ? Many label them as just online advertising companies. 

But Facebook could seemingly become the world's largest entertainment company, while Alphabet is a data center and cloud behemoth, with a self-driving car unit in Waymo to boot.

Long-term investors would be foolish to discount these future earnings generators and should consider just how valuable these companies can be down the road. 

Executive Decision: Adobe

Adobe Systems (ADBE)  is a stock Cramer knows well, thanks to it being a holding in his Action Alerts PLUS portfolio. That's why he was excited to sit down with CEO Shantanu Narayen and discuss the business. 

The company has two massive tailwinds, according to Narayen: Design and digital transformation. 

Everyone has a story to tell and Adobe's helping them tell it, whether it's individual artists and designers or large Fortune 500 companies. As that creativity continues to grow and become more personalized, Adobe continues to finds itself in the sweet spot. 

Mobile is becoming such a powerful source as well. Companies' ability to reach their customers on this platform is becoming more and more important, Narayen said. They need to deliver the right ad and the right content at the right time. When it becomes personalized and tailored to specific customers, that's the holy grail. 

While Adobe has some of those tailwinds working its favor, Narayen says the overall business climate feels good and seems to be doing better. 

The company's incredible free-cash-flow growth is stunning, Cramer said. Even with the stock near 52-week highs, it seems likely that it can continue higher. 

The Lightning Round

In the Lightning Round, Cramer was bullish on Nvidia (NVDA) , Hershey (HSY) , Accenture (ACN) , Cheniere Energy (CQP) , Inovio Pharma (INO) and Schlumberger (SLB) . 

He was bearish on Emerge Energy Services (EMES) and Seaspan (SSW) .

Executive Decision: General Electric

When we think of groundbreaking technology, our minds usually drift to the hot, snazzy companies out West working in automation, artificial intelligence and cloud computing. But don't forget about the old and established players, like General Electric (GE) . 

Jim Cramer sat down with GE CEO Jeff Immelt to discuss some of the company's more technological developments that don't seem to get the credit they deserve. 

GE is aiming to be a top 10 software company by 2020 and based on its customer orders, it's about halfway there. Those orders are growing at about 25% per year, Immelt added. 

The company's success or failure over the next decade will largely be determined by GE's digital transformation. Industrial companies need to stake their digital claim, both for offensive and defensive reasons, Immelt said. 

Immelt explained that GE will be lowering costs and improving productivity for industrial, energy, health care and other companies. And while this will be a big market in the future, with plenty of competitors, GE already has a big advantage by having such an established customer base. 

The country has been in an investment recession for about 10 or 15 years, he added. But now companies are investing in technology and productivity gains. 

Contrary to what many believe, that doesn't directly translate to increased automation and fewer jobs. Immelt said it will instead mean more valuable employees becoming more productive.
