Vestis Corporation's stock plummeted 5.25% during intraday trading on Wednesday, reversing earlier gains from the pre-market session.

The stock had initially gained 3.1% in pre-market trading following an upgrade from William Blair, which raised its rating on Vestis to Outperform from Market Perform. This positive analyst action had boosted investor sentiment early in the trading day.

However, the rally was short-lived as Stifel maintained its Hold rating on Vestis Corporation, with the announcement coming just minutes before the sharp decline. This maintained rating from Stifel, coupled with Baird's earlier decision to maintain a Neutral rating, tempered the initial optimism and triggered selling pressure that led to the significant intraday drop.
