What happened Shares of Square (NYSE: SQ) stock surged 4.9% in Wednesday afternoon trading, as of 1:40 p.m. EST, after the company announced it has reached a "definitive agreement" to acquire the Credit Karma Tax unit of consumer credit report provider Credit Karma. So what Square will acquire the free tax-filing service and add it to its own Cash App subsidiary in a deal valued at $50 million, cash. In a statement, Square explained that its new acquisition "will expand Cash App's diverse ecosystem of financial tools -- which currently includes peer-to-peer payments, Cash Card, direct deposit, as well as fractional investing ... giving customers another way to manage their finances from their pocket." In so doing, Square will also clear the way for Intuit (NASDAQ: INTU) to proceed with its own planned acquisition of the rest of Credit Karma. The U.S. Department of Justice had been holding up this latter acquisition, telling Intuit it could acquire Credit Karma, but only if the latter first divested its tax-filing business.

But is it good enough news to justify investors valuing Square at roughly $3.7 billion more in market capitalization today than the stock was worth yesterday? All because of a $50 million acquisition to the business? I don't think so. And with Square stock now valued at a staggering 317 times trailing earnings, I think I'd be more inclined to use today's share price spike as an opportunity to exit Square stock than to buy any more. 10 stocks we like better than SquareWhen investing geniuses David and Tom Gardner have a stock tip, it can pay to listen.
