"First, President Trump went hardline against Iran and their oil exports have plummeted while Venezuelan exports continue to dwindle, and demand is increasing well north of what it's been for ages and ages," the "Mad Money" host said.
Those supply and demand issues suggest that on a fundamental basis, oil prices are ripe for a rebound and "the oil rally is for real," Cramer told investors.
"To me, that means the oil stocks are worth owning here," he said. "I think BP, the old British Petroleum, makes the most sense because you get that terrific 5 percent yield. If you're going to be wrong, you get protected. If you want to be more aggressive, go with an independent producer like Diamondback Energy."
Most of all, "don't let an overdeveloped sense of caution trick you into missing these straightforward moves," the "Mad Money" host said. It could cost you.

The business of business is improving the state of the world," Benioff said, speaking from Salesforce's Dreamforce conference in San Francisco.

"I think a big misunderstanding is that people thought that people are buying storage when, really, ... 80 percent of our subscribers, more than that, are using Dropbox at work," the CEO said. "And they're really buying sharing and collaboration and the ability to work better with other people."
