What Happened?
Shares of safety and security company Federal Signal (NYSE: FSS) fell 4.7% in the afternoon session after Keybanc analyst downgraded the stock. The investment firm lowered its rating on the specialty vehicle manufacturer to "Sector Weight" from a previous "Overweight" rating. The primary reason cited for the downgrade was the stock's valuation, following a significant 58% surge in its share price since early April. Analysts at KeyBanc noted that this impressive run has made Federal Signal one of the more expensive stocks in the construction machinery sector based on 2026 estimates.
While the firm maintains a positive long-term view of the company's strategy, it believes these strengths are now fully reflected in the current stock price, suggesting limited near-term upside. The downgrade also pointed to challenging order comparisons ahead for the company.
