Chipotle Mexican Grill’s stock plummeted 19% after cutting its full-year same-store sales forecast for the third straight quarter. The stock has fallen 45% this year, with a market value now around $43 billion. Analysts are concerned about the chain’s shrinking traffic and gloomy outlook, with some revising price targets.

In the third quarter, Chipotle’s same-store sales rose 0.3%, but its traffic fell. Analysts are unsure if the chain’s value perception is contributing to its issues. CEO Scott Boatwright said sales have worsened in October, projecting a mid-single digit percentage decline for the full year. Most analysts attribute the slowdown to industry-wide challenges.

Chipotle’s weak performance is a bad sign for fast-casual peers like Sweetgreen and Cava. Morgan Stanley analyst Brian Harbour called fast-casual restaurants “This Season’s Halloween Scare” after Chipotle’s earnings report. Shares of Sweetgreen fell 6% and Cava stock was down 8% in morning trading. Both are set to report third-quarter results next week.
