Do you know what stock dropped almost 100 points on Friday? This is not counting Berkshire Hathaway (BRK-A) (BRK-B) which was down 1265 points. The stock that was down big time to the tune of 21.5% was Chipotle Mexican Grill, Inc. (CMG), the operator of numerous Mexican restaurants throughout the US. This has been a hot stock of late, closing at 403.86 last Thursday, but dropping as low as 307.20, down about 96 points, then closing at 316.98. The company reported sales below what Wall street analysts were expecting, which in turn, triggered several downgrades for the stock. The stock trades around 29 times forward earnings and does not pay a dividend.
