NEW YORK (TheStreet) -- Convincing growth investors that valuation will always matter has become quite the challenge. This is particularly true when stocks such as Amazon (AMZN) and Salesforce.com (CRM), which enjoy enormous valuation multiples, continue to make fools out of people like me who insist on raising the subject.However, every now and then an event occurs that reminds investors that expecting certain companies to consistently break the rules of future growth is a risky proposition, if not absurdly dangerous. This seems to be the case for Chipotle Mexican Grill ( CMG), which has now disappointed the Street in two consecutive quarters. On the heels of another round of punishment, investors want to know if the stock is now a great buy or still a value trap. For the third quarter, Chipotle reported net income of $72.3 million, or $2.27 per share, on revenue of $700.5 million. The company missed EPS estimates of $2.33 per share while also falling short of revenue projections by $6.6 million. But this wasn't all bad. While the company did miss on its top and bottom line estimates, however, both earnings and revenue grew by 20 and 18%, respectively, from the same period of a year ago. What's more, this marked the third consecutive quarter in which Chipotle has enjoyed rising net income while keeping consistent with its average revenue growth of 22%, which now spans five quarters. P/>Likewise, during that same period, Chipotle's net income has produced averaged year-over-year growth of 30%.However, as great as these facts are, it seems analysts cared more to pay attention to the here and now. Investors were displeased the company's margins arrived lighter than expected and that same-store sales grew just under 5%, down from last year's quarter of 11% and also falling from the previous quarter's mark of 8%. Consequently, following the announcement, Chipotle lost over 15% of its value as the stock plummeted to $243 per share from a previous close of $285 in what I can on describe as a gross overreaction.
