Trip.com Group Ltd (NASDAQ:TCOM) is a leading travel service provider, offering a comprehensive range of travel services including hotel reservations, transportation ticketing, and packaged tours. The company operates primarily in China but has a global presence. It competes with other travel giants like Expedia and Booking Holdings. Recently, Citigroup maintained a "Buy" rating for TCOM, despite a "hold" action, with the stock priced at $62.99.

On January 14, 2026, Citigroup's confidence in Trip.com remains firm, even as the company faces an antitrust probe by China's business regulator. This investigation is focused on a suspected monopoly, as highlighted by Schaeffer's Research. Despite this, Citi believes the probe is unlikely to impact Trip.com's industry position significantly.

The announcement of the probe has led to a sharp decline in TCOM's stock, which fell 16% to $63.59, marking its largest single-day percentage loss since November 8, 2018. The stock is now trading at its lowest levels since August and has dropped below its 120-day moving average, which had previously provided support in December.

The stock's current price is $62.10, reflecting a decrease of 17.94% with a change of $13.58. It has fluctuated between a low of $61.40 and a high of $64.84 today. Over the past year, TCOM has reached a high of $78.99 and a low of $51.35. The company's market capitalization is approximately $40.85 billion.

Options traders are showing increased bearish sentiment, with a 50-day put/call volume ratio of 1.05, higher than 97% of similar readings in recent history. This indicates a growing concern among investors about the potential impact of the antitrust probe on Trip.com's future performance.
