"Jim Fish, CEO of Waste Management who comes on all the time on the show, often commented that his best source of revenue is construction," the "Mad Money" host said. "Waste Management just announced the acquisition of a competitor. Business is good, getting better. That's the one to buy."
The company announced on Monday it purchased Advanced Disposal for about $3 billion. The stock is up more than 18% in 2019.
CSX Transportation's Tuesday earnings call gave some insight into what stocks could be worth playing, Cramer said.
"If you want to get an honest read on the economy, forget the government data from the Commerce Department," he said. "You got an incredible snapshot of the economy from CSX, the best railroad around with a stock that caught fire today."
The stock rose 4% during the trading day. The major U.S. indexes all dipped.
CSX was the first of the railroad stocks to report its most recent quarterly results, and its revenue break down gave a good look at the domestic economy, Cramer said.
"I was amazed at how strong their business is ... Sure, CSX is an east-southeast railroad for the most part and its business doesn't of course stretch overseas," he said. "But that's why it's such a terrific tell for what's happening in the U.S. economy, and it's also fabulous source of inspiration if you're on the hunt for new stock picks."

Campbell Soup appears to have emerged out of the wilderness after a series of acquisitions of brands that nobody truly wanted, Cramer said. The stock is down about 8% from a year ago, but it's rallied more than 18% in 2019.
"With the stock now trading at 15.7-times next year's earnings estimates, I'm not sure how much upside it has left if [activist investors] can't find some way to engineer a sale," Cramer said. "The deck seems a little stacked against that outcome to begin with. However, if things go south, I think that could make a sale a genuine possibility."
Coming off the bank's latest earnings report, Cramer asked First Horizon National Corp. CEO Bryan Jordan his thoughts on the state of interest rates.
"If I had to guess, I'd say it's flat for a while and then down," he told the "Mad Money" host.

Cramer said investors could expect to see more mergers and acquisitions in the energy and oil space in 2019.
"Anadarko was the first big oil deal this year, but I bet it won't be the last," he said. "That's why I like Apache, I like Concho, Parsley, and especially Pioneer Nat, because this industry still needs much more consolidation."
Chevron made a move on Friday to purchase the oil and gas driller in a cash-and-stock deal worth $33 billion. Cramer had anticipated a merger in the energy and oil sector because the market is crowded. There could be more to come, especially since Occidental had made a competing bid for Anadarko, he said.
"Three weeks ago, I did make a called shot. I came out here and explained that this market was in dire need of mergers and acquisitions," he said. "We've simply got too many publicly traded companies, something that's only going to get worse as more and more privately held unicorns, like Pinterest tonight, keep coming public."
