Serve Robotics Inc (SERV) experienced a sharp decline in the pre-market session, with its stock plummeting 5.11% following a downgrade from Seaport Research Partners. The robotics company's shares faced significant selling pressure after the research firm lowered its rating from Buy to Neutral.

The downgrade came in the wake of Serve Robotics' recent second-quarter report, suggesting that the company's performance or outlook may have fallen short of analysts' expectations. Seaport Research analyst Aaron Kessler issued the downgrade without specifying a price target, indicating a cautious stance on the company's near-term prospects.

This rating change represents a significant shift in sentiment for Serve Robotics, which had previously enjoyed a more optimistic outlook from Seaport Research. The market's strong negative reaction underscores the weight that analyst opinions carry, particularly for companies in the innovative but volatile robotics sector. Investors will likely be closely watching for any further developments or clarifications from the company regarding its recent quarterly performance and future outlook.
