Piper Sandler upgraded Chipotle Mexican Grill Inc. to Overweight on Tuesday, saying the burrito chain’s recent share-price pullback offers an attractive entry point for investors. The brokerage firm said it sees scope for a recovery and forecast the stock could gain more than 20% as margin pressures ease and new store openings resume their pre-pandemic trajectory. Piper Sandler added that its revised risk-reward calculations favor buying the shares at current levels.
