Today's big market rally may last a lot longer than the bears think, Jim Cramer told his Mad Money viewers Thursday. Forget about FANG, Cramer's acronym for Facebook (FB) - Get Facebook, Inc. Class A Report , Amazon (AMZN) - Get, Inc. Report , Netflix (NFLX) - Get Netflix, Inc. (NFLX) Report and Alphabet (GOOGL) - Get Alphabet Inc. Class A Report , formerly Google. Today, the market was in love with WANG.

Cramer said that Walmart (WMT) - Get Walmart Inc. Report  (at least for the moment) replaced Facebook as a must-own stock, after the company reported earnings so strong, investors felt compelled to buy, sending shares up 9.3%. Walmart's strength came largely from its commerce operations, which rocketed 40%, surpassing all of its brick and mortar rivals. Could the company one day give Amazon (AMZN) - Get, Inc. Report a run for it's money?

The market was also buoyed by the possibility of trade talks resuming with China. Cramer said even low level talks are better than no talks.

But beyond Walmart and trade, Cramer said he was impressed with the breadth of today's rally, which included tech, the financials and even some industrials, like Boeing (BA) - Get Boeing Company Report .

Executive Decision: American Electric Power

For his "Executive Decision" segment, Cramer spoke with Nick Akins, chairman, president and CEO of American Electric Power (AEP) - Get American Electric Power Company, Inc. Report , a company Cramer called his favorite utility.

Akins reaffirmed AEP's growth target of between 5% and 7%, saying that business remains strong throughout their service area.

When asked about AEP's decision to cancel their Wind Catcher project, which would have been our country's largest wind generation facility, Akins said that they were very disappointed that the project was not approved by Texas regulators. However, he said that AEP is built on a solid foundation, which means they can be selective about the projects they move forward with. Wind Catcher will just be replaced by smaller renewable energy projects.

Turning to the topic of electric vehicles, Akins explained that building infrastructure to support EV charging is a major effort and one that AEP is very involved with. His company will benefit from not only building these stations, but also supplying power to them.

Make Room for IAC/Interactive 

The stock of IAC/Interactive (IAC) - Get IAC/InterActiveCorp. Report as been roaring lately, but Cramer told viewers he thinks the stock has a lot more room to run.

In the weeks leading up to earnings, shares of IAC ran from $147 to $168. But after the company reported another strong quarter, shares continued higher, all the way to $182. All told, IAC shares are up over 76% during the past 12 months.

Cramer said the IAC story is all about valuation. The company owns a majority stake in Match Group (MTCH) - Get Match Group, Inc. Report , which is valued at $10.4 billion, and Angie's Holdings for another $8.1 billion. A little arithmetic and that totals $18.5 billion. Yet IAC overall has a market cap of just $15.4 billion.

What are investors getting for their negative three billion dollars? Plenty. The company has a thriving online publishing business, a mobile and desktop app development arm and Vimeo, a subscription-based video publishing platform for businesses.

Cramer said IAC remains a buy and he thinks shares can still go a lot higher.

Smith (AOS) - Get A. O. Smith Corporation Report and Intel (INTC) - Get Intel Corporation (INTC) Report .

No-Huddle Offense

In his "No-Huddle Offense" segment, Cramer opined on last night's interview with U.S. Senator Elizabeth Warren. He said while he agrees with Warren that median incomes have been flat for decades, he's skeptical that the ideas Warren proposed will work.

It's no secret that employees who are respected and paid well perform better than those that aren't. Cramer said he learned this lesson from Mark Benioff at (CRM) - Get, inc. Report , John Sinegal at Costco (COST) - Get Costco Wholesale Corporation Report and Patrick Doyle of Domino's Pizza (DPZ) - Get Domino's Pizza, Inc. Report . All three of these fantastic CEOs shared their wealth and success with employees and they didn't need federal regulations to do so.
