Analyst Update: Chipotle, CalAmp, and Delphi Auto

Analysts are weighing in today on fast-casual joint Chipotle Mexican Grill, Inc. (NYSE:CMG), wireless communications expert CalAmp Corp. (NASDAQ:CAMP), and autoparts maker Delphi Automotive PLC (NYSE:DLPH). Here's a quick roundup of today's brokerage notes on CMG, CAMP, and DLPH.

• CMG is up 0.6% this afternoon at $497.34, but earlier hit an annual low of $482.23 after getting hit with a price-target cut to $550 from $575 at RBC. Currently, the stock is trying to fight back from E. coli-related losses, which have impacted consumer eating habits. Today, in fact, Chipotle Mexican Grill, Inc. announced it will change the way food is prepared at its restaurants to address mounting safety concerns. On the sentiment front, the brokerage crowd is tilted in a skeptical direction. Of the 25 analysts tracking CMG, 56% have handed out a "hold" or worse recommendation.

• Following last night's record-setting earnings report, CAMP received a $1 price-target bump to $27 at Canaccord Genuity. As such, the shares have soared 7.4% to trade at $20.89, bringing their 2015 lead beyond 14%. This is music to the ears of option bulls, who have been buying to open CalAmp Corp. calls over puts at a breakneck pace in recent months. Specifically, the stock's 50-day call/put volume ratio of 8.35 across the International Securities Exchange (ISE), Chicago Board Options Exchange (CBOE), and NASDAQ OMX PHLX (PHLX) rests just 1 percentage point from an annual high. 

• DLPH has popped 2.5% to $86.65, on the heels of an upgrade to "buy" from "neutral" at Sterne Agee CRT. This is more of the same for a stock that's advanced nearly 20% on the year, and is hovering just a stone's throw from its annual high of $90.57, set in late June. Wall Street is divided on the technical outperformer. On the one hand, 80% of covering analysts rate Delphi Automotive PLC a "buy" or better, with not a single "sell" opinion on the books. On the other, the stock's 10-day ISE/CBOE/PHLX put/call volume ratio checks in at a top-heavy 4.32 -- outstripping 84% of comparable readings from the prior year.
