Shrewd investing involves a lot of work. Not only must you determine what to bet on, you must also determine what never to bet against.
And Cramer says never bet against hot trends.
Right now, the Mad Money host thinks 'the cloud' is about the hottest trend going. "Especially when it's integrated with social offerings," Cramer said.
And Cramer thinks few companies are better positioned to leverage the trend than Marketo, a company that just came public earlier in 2013.
"Marketo's cloud-based software helps its clients streamline their marketing decisions and build long-term relationships with their customers, including through social media," explained Cramer.
Although shares are up more than 40% since the IPO, which was less than 3 months ago, Cramer would not advocate shorting the stock.
