Warren Buffett's company, Berkshire Hathaway , is a "clear buy," Cramer said on Monday's Stop Trading!.
"This is one of the finest operating quarters I've seen from Berkshire," he noted. "The railroad is on fire."

Operating profit increased by 73%, but a 40% drop in second-quarter income drew more attention Friday.
"The headline was all wrong," Cramer said, adding that Berkshire has the "single-best chart in the whole book."
Elsewhere in the market, shares of McDonald's hit an all-time high Monday after the fast food giant reported better-than-expected July sales data.
Cramer called the restaurant chain operator a "really well-run company" and praised CEO James A. Skinner. He said McDonald's has found success by adding to its menu and noted it is accelerating earnings. If the euro goes to 1.40, he thinks there will be easier compares in the fourth-quarter.
The Mad Money host also continued his push for a public IPO for General Motors, so that US taxpayers who funded the bailout of the once-bankrupt automaker will have the chance to invest in the company.
