On this episode of Stock Movers, we take a look at some of the week's biggest movers:

• Fiserv (FI) ended the week down nearly 47% after the fintech firm slashed its full-year earnings guidance. Chief Executive Officer Mike Lyons, who took the reins in February, said he discovered that Fiserv wasn’t going to be able to deliver on its previous promises to investors after he undertook a broad-based review of the business in recent months. 
• Alexandria Real Estate (ARE) ended the week lower after the health-care REIT cut its adjusted FFO guidance for 2025 and posted 3Q results that fell short of expectations. Cantor Fitzgerald called the report “as tough as it gets.”
• Chipotle (CMG) ended the week down 23% after cutting guidance for the third time this year. The company saw a broad pullback in visit frequency across all income cohorts, though lower-income consumers were particularly strained. “The consumer slowdown is really affecting our business in a meaningful way,” Chief Executive Officer Scott Boatwright said in a call with analysts on Wednesday
