Starbucks Stock Is Down 15% This Month. Time to Buy?
Brian Niccol turned around Taco Bell and Chipotle. Can he work the same magic at Starbucks?

Coffee giant Starbucks (NASDAQ: SBUX) could use some Wall Street caffeine these days.
As of this writing on March 18, the stock is down 15% since the end of February. The broader market is also swooning with a 5.6% S&P 500 (SNPINDEX: ^GSPC) decline in the same period, but Starbucks is taking a deeper dive.
Is the company in deep trouble, or is it high time to buy Starbucks stock?
