Trip.com Group Limited (TCOM) experienced a significant intraday plummet of 5.80% on Thursday, reflecting heightened investor concerns over recent regulatory developments.

The sell-off appears driven by escalating regulatory scrutiny. Beijing market regulators recently held a meeting with Trip.com and other major online train ticket sales platforms to address consumer complaints about misleading promotional practices. Additionally, last month, China's State Administration for Market Regulation launched an antitrust investigation into Trip.com for suspected abuse of market dominance, a probe the company has stated it will fully cooperate with.
