When big-cap stocks act like start-ups, then maybe they're cheaper than we think, Jim Cramer told his Mad Money viewers Tuesday.

Stocks are, after all, valued on their future earnings potential, and if this quarter is any guide, the future is looking very good.

Case in point: Johnson & Johnson (JNJ) , a company with a stellar balance sheet and sales that are up 15%. Shares trade for just 18 times earnings, Cramer said, well below its peers like Colgate-Palmolive (CL)  , at 26 times and Clorox (CLX)  , at 24 times earnings.

Another cheap stock is UnitedHealth Group (UNH) , which posted 21% revenue growth but trades at 19 times earnings. Earnings at Morgan Stanley (MS) keep getting better, but that company trades at a paltry 14 times earnings, as does JPMorgan Chase (JPM) .

Cramer called these valuations ridiculous. He said the airlines are also undervalued, as is General Motors (GM) , which he discussed on last night's show, at a scant seven times earnings.

Then there are the stocks that defy the four walls of the spreadsheet, Amazon (AMZN) , Netflix (NFLX) and Tesla (TSLA) , which seem to know no bounds at all.

Back in 1987, right before the crash (the anniversary of which is this week), the average stock traded at 29 times earnings. Interest rates were at 7%. Cramer said this market is nothing like 1987.

Off the Charts: Consumer Staples 

In the "Off The Charts" segment, Cramer checked in with colleague Ed Ponsi over the charts of the consumer staple stocks to understand what's happening with the losers and laggards in this otherwise red-hot market.

Ponsi first looked at a daily chart of the Consumer Staples Select Sector SPDR ETF (XLP) , which follows names like Procter & Gamble (PG) , Pepsico (PEP) , Walgreens Boots (WBA) and Costco (COST) .

The Staples ETF has been essentially flat since February, Ponsi said, recently making a bearish head-and-shoulders pattern. The ETF is already below its 50-day and 200-day moving average, and the averages just made a death cross, where the 50-day falls below the 200-day.

Among the worst performers in the group was Kraft Heinz (KHC) , which also recently saw a death cross in August and has been plummeting ever since. The chart of General Mills (GIS) and J.M. Smucker (SJM) weren't faring any better, making series of lower highs and lower lows and having some of the worst charts possible.

Cramer said these stocks are clearly not done going lower and he'd continue to steer clear of all of them.

Netflix Finds it's Hard to Impress 

Netflix just posted a fabulous quarter, but after an initial spike, shares closed down 1.5% by the end of the day Tuesday. What happened? Cramer said there was a lot of hype and a wave of bullish analyst reports going into the quarter, and when everybody is expecting the moon, it's hard to impress.

Cramer reminded viewers that Netflix doesn't trade on earnings, it trades on subscriber growth, where the company posted 5.3 million new subscribers when analysts were only looking for 4.5 million. Even with Netflix mastering the art of under-promising and over-delivering, the markets were still not impressed.

There are some things to be concerned about, Cramer admitted, including the company's cash burn and its piling debt. Then again, the company continues to deliver fabulous content that viewers are willing to pay up for, so over the long haul, this probably won't be a problem. That's why Cramer said he's still a believer in Netflix and would use this weakness as a buying opportunity.

Off the Tape: ThoughtSpot

In his "Off The Tape" segment, Cramer sat down with Ajeet Singh, founder and CEO of the privately-held ThoughtSpot, a search-driven data analysis engine powered by artificial intelligence.

Singh explained that for every data analyst a company has, there are typically 600 users with questions that need to be answered. ThoughtSpot aims to liberate both the users and the analysts by using artificial intelligence.

Using his company's software, users can ask questions using natural language and get back answers, reports, charts or dashboards to their queries. Using AI, ThoughtSpot can even deduce which questions should be asked and provide answers for those questions as well.

Most of ThoughtSpot's clients are large enterprises, Singh said, and his company's software can be layered on top of any system of record.

Cramer and the AAP team are optimistic that the Broadcom (AVGO) - Brocade (BRCD) deal will eventually go through, helping Broadcom break out from this mixed trading pattern.

Lightning Round

In the Lightning Round, Cramer was bullish on Delta Air Lines (DAL) , BioTelemetry (BEAT) , Littelfuse (LFUS) , Emerson Electric (EMR) , TransUnion (TRU) , Amgen (AMGN) and Dave and Busters (PLAY) .

Cramer was bearish on Sangamo BioSciences (SGMO) , Esperion Therapeutics (ESPR) and Kinder Morgan (KMI) .

No-Huddle Offense: The Fun Bunch 

In his "No-Huddle Offense" segment, Cramer proposed that someone create a "fun" ETF, one that includes only companies with CEOs that are really enjoying themselves.

That ETF would surely include Netflix, which boasts a non-traditional conference call that sometimes includes execs wearing ugly sweaters. It would also include T-Mobile (TMUS) , with it's colorful CEO John Legere. Constellation Brands (STZ) is always upbeat on their conference call, as is Tesla (TSLA) CEO Elon Musk. And there are always good times to be had on the Restoration Hardware (RH) call as well.

What do all of these companies have in common? They project confidence, which in turn instills confidence in us, the shareholders.
