NEW YORK ( TheStreet) -- A friend of mine once told me, "Never underestimate the power of great burrito." He said this jokingly because I loathed the idea of overspending for a meal I believed was worth half the price.
I won't disagree that Chipotle makes a "powerful" burrito. But I continue to worry investors are too willing to give Chipotle the benefit of the doubt as the company's operational performance has not been up to par when compared to Yum! Brands (YUM) and McDonald's (MCD).
Remarkably, as Chipotle's margins are compressing and same-store sales are weakening, the stock is up an impressive 30% year-to-date. With second-quarter earnings due out Thursday, I can't stomach holding this stock, especially since the April quarter raised several red flags.For instance, even though first-quarter revenue were up 13% year over year, it was also clear the rising costs of protein had taken a toll on the company's margins. That food costs were 33% of Chipotle's revenue is cause for indigestion. The way I see it, as long as food costs remain at such a high percentage of revenue, this will continue to add pressure on management to raise prices - there's no way around it. And investors will demand it.
