Jim Cramer says Wall Street's latest trading trend is creating buying opportunities

CNBC's Jim Cramer said stocks are increasingly moving as part of thematic trading baskets rather than on company-specific fundamentals. He said the disconnect often creates buying opportunities for investors willing to focus on business performance.

CNBC's Jim Cramer on Monday said Wall Street's "basket trades" during the Iran war are distorting stock prices, urging investors to use the dislocations to their advantage.

"The best thing? They create real opportunities, as the stocks divorce themselves from the fundamentals until the companies report," the " Mad Money " host said.

Cramer said traders have increasingly grouped stocks into baskets that rise or fall together based on broad themes rather than company-specific fundamentals. While those trades often dominate day-to-day price action, particularly as the Middle East conflict stretches on, he argued they frequently have little to do with a company's long-term prospects.

He pointed to Boeing as one example. The planemaker's shares have increasingly traded with geopolitical headlines, rallying on signs of diplomacy and selling off when the conflict escalates. Despite this linkage, Cramer said the daily headlines do not change the company's long-term outlook.

"Boeing, the company, not Boeing the trading plaything, gets valued on cash flow and production," he said, noting the company's backlog of roughly 6,200 aircraft should matter far more than short-term developments in the Middle East.

Retailers have become another basket trade, according to Cramer. When geopolitical tensions and higher oil prices raised concerns about inflation, Cramer noted investors rotated into retailers such as Costco and Walmart — two perceived winners when shoppers are feeling squeezed at the gas pump — and out of more discretionary names such as Ralph Lauren , Target and Williams-Sonoma .

"Costco and Walmart are both excellent evergreen retailers," he said.

Cramer said technology became one of Wall Street's biggest basket trades. For the first half of the year, investors broadly favored artificial intelligence infrastructure stocks, while selling enterprise software, regardless of how their businesses were faring. He said the market assumed hardware companies would be the biggest beneficiaries of the AI boom and software providers would struggle as AI disrupted their business models.

As that trade began to reverse, he said companies with stronger fundamentals, including ServiceNow and Salesforce , started to break away from the software pack.

He acknowledged basket trading can overwhelm fundamentals in the short term, but said earnings season eventually forces investors to refocus on individual companies.

"It's good to see that the fundamentals still matter, even if it only happens during earnings season, four times a year," he said.
