Enjoy the stock market's strength while you can, Jim Cramer warned his Mad Money viewers Thursday. There's not enough of the market that can go higher, he cautioned, and that means selling into rallies and raising cash where you can.

Cramer explained that the markets are being ruled by the "twos and tens," more specifically the yields on the 2-year compared to the 10-year Treasuries. Why is this important? Cramer said it's because a tight-spread, like we're seeing now, is unusual and typically a harbinger of an upcoming recession. This is a strong signal that bond traders and money managers aren't likely to ignore, which is why we're seeing weakness in the financials and the homebuilders, which are the most interest-rate sensitive.

The markets are also paying close attention to another "T", and that's tariffs. Retaliation from China is likely as the next round of President Trump's tariffs take effect. As a result, means money managers will be selling the industrials, especially the auto makers. They're also weary of tech stocks and companies like Starbucks (SBUX) , where China could choose to interfere or boycott.

That doesn't leave many safe places to invest, Cramer admitted, which is why he's tempering his bullishness and sticking with small-cap stocks and domestic names that aren't affected by trade or interest rates.

FANG Stocks Still a Winning Hand 

Sometimes, it's better to be lucky than good, Cramer reminded viewers, which is why the FANG stocks (his acronym for Facebook (FB) , Amazon (AMZN) , Netflix (NFLX) and Alphabet (GOOGL) ) continue to shine.

In a market that's worried about tariffs, and China in particular, Cramer said, it's a happy coincidence that FANG has nothing to do with China. FANG also has secular growth that trumps the possible economic slowdown caused by tariffs or trade.

What else does FANG have going for it? These stocks are also immune to inflation, whether it be from commodities, freight, or oil.

None of the FANG stocks are sitting still, either. Cramer said Facebook's business is accelerating, especially at Instagram, while Amazon's acquisition of Pillpack was a brilliant move into the pharmacy space.

Netflix, meanwhile, continues to innovate -- leaving Alphabet as the laggard, up only 8% for the year. But Cramer noted that Alphabet has a ton of cash and a lot of opportunities in front of it, making it a worthy member of FANG.

So while nothing lasts forever, Cramer conceded, FANG has sustained the stock market since he first coined the term five years ago.

IPOs: Supply and Demand 

The market for IPOs remains hot, Cramer told viewers, but that doesn't mean investors should jump on every deal that comes along. As he warned three weeks ago, the enterprise software market had overheated, and since then stocks like Carbon Black (CBLK) have fallen 28%.

In the end, the IPO market is always about supply and demand, and with the highest supply since 2012, investors need to be vigilant, especially with private equity-backed and Chinese-based deals.

Cramer said he's still a fan of Dropbox (DBX) and Spotify (SPOT) , but questioned whether the Chinese IQIYI (IQ) or Bilibili (BILI) are worthy of a spot in your portfolio. Now that shares of Zuora (ZUO) have cooled, he suggested taking another look at this company as well.

Executive Decision: Paychex 

For his "Executive Decision" segment, Cramer checked in with Marty Mucci, president and CEO of Paychex (PAYX) , the payroll processor with its finger on the pulse of the economy.

Mucci said that despite in-line earnings this quarter, Paychex had a solid year and a strong quarter with 7% revenue growth and a 12% increase in its dividend. He said the extra profits from tax reforms earlier this year were spent on returning capital to shareholders and on creating new and better products for customers.

One of the bright spots for Paychex has been human resource outsourcing. Mucci explained that harassment has been top of mind for many small businesses and without a full human resource department, these customers are turning more and more to Paychex for help.

When asked about our economy, Mucci said the South continues to see the best growth, while the West has the highest wage growth at the moment. The top sector continues to be manufacturing, although growth has slowed slightly from previous levels.

Lightning Round

In the Lightning Round, Cramer was bullish on Shake Shack (SHAK) , Jack Henry & Associates (JKHY) , Kraft Heinz (KHC) , Magellan Midstream Partners (MMP) , Enbridge (ENB) , FedEx (FDX) , Adobe Systems (ADBE) , Blackberry (BB) and Marathon Petroleum (MPC) .

Cramer was bearish on Kinder Morgan (KMI) .

No-Huddle Offense

In his "No-Huddle Offense" segment, Cramer said that while negativity is defining the moment, it's simply not right.

Cramer said he heard it on conference call after conference call -- breathtaking pessimism from analyst after analyst. It didn't matter if it was spicemaker McCormick (MKC) , furniture maker Herman Miller (MLHR) or home-builder KB Home (KBH) , the negativity was everywhere.

But in the end, Cramer said, Herman Miller's CEO said it best, when he pointed out that while politics and the global environment makes him nervous, there are no signs that any of it is affecting their business.
