On January 14, 2026, the State Administration for Market Regulation opened an investigation into Trip.com Group Limited on suspicion of abusing its dominant market position to engage in monopolistic practices. Affected by this, Ctrip’s U.S. stock plummeted by over 17% in a single day, with its Hong Kong stock continuing the downward trend[1][2]. This incident triggered deep market concerns about internet platform regulation, as investors recalled the 2021 antitrust penalties imposed on Alibaba (a fine of RMB 18.228 billion) and Meituan (a fine of RMB 3.442 billion), putting overall pressure on the internet Chinese concept stock sector[3].

Even more alarming is that China has expanded its investigation into Pinduoduo (PDD, parent company of Temu). According to Bloomberg, regulators dispatched over 100 investigators to Pinduoduo’s Shanghai headquarters, following a negative incident involving physical conflict between employees and regulators[4]. This has caused Pinduoduo’s stock price to drop 11.44% in the past week and 16.17% in the past three months[5].

On January 15, 2026, the three major U.S. stock indices closed lower collectively, with the Nasdaq leading the decline (-0.69%), and tech stocks generally weakened[6]. Financial stocks such as JPMorgan Chase and Wells Fargo continued to decline after releasing their earnings reports, dragging down the broader market performance. The pressure on bank stocks stems from market concerns about the credit card interest rate cap plan proposed by Trump[7].

U.S. November PPI rose 3% year-on-year, higher than the market expectation of 2.7%; core PPI rose 3% year-on-year, also exceeding expectations[8]. This has strengthened market expectations that the Federal Reserve will maintain a tight monetary policy, putting pressure on high-valued growth stocks.

In November 2025, the State Administration for Market Regulation issued the Guidelines for Antitrust Compliance of Internet Platforms (Draft for Comments), clarifying 8 types of monopolistic risk scenarios, including algorithmic collusion between platforms, organizing or assisting operators on the platform to reach monopolistic agreements, unfair high pricing by platforms, and exclusive dealing practices[9]. Throughout 2025, China investigated and handled 35 monopoly agreement cases and 25 cases of abusing dominant market position, with total fines and confiscations reaching RMB 2.93 billion[10].

Industry analysts believe that the country’s approach to monopolistic practices in the platform economy has shifted from concentrated penalties to normalized regulation[11]. The 2026 National Market Regulation Work Conference further clarified that “strengthening normalized supervision of the platform economy” and “consolidating the ‘gatekeeper’ responsibilities of platform enterprises” are listed as key tasks[12].

U.S. President Trump announced a 10%-25% tariff increase on 8 countries including Denmark, Norway, Sweden, France, Germany, the UK, the Netherlands, and Finland, escalating geopolitical uncertainty[13]. Meanwhile, the U.S. imposed a 25% tariff on some imported semiconductors and semiconductor manufacturing equipment, affecting the valuations of Chinese concept tech stocks[14].

Starting from January 19, 2026, the minimum margin ratio for margin purchases by investors on the Shanghai, Shenzhen, and Beijing Stock Exchanges will be increased from 80% to 100%[15]. Although this “grandfathering” policy mainly affects the A-share market, it also has a knock-on effect on market sentiment in Hong Kong stocks and Chinese concept stocks.

Pinduoduo’s latest financial report shows revenue of USD 1.521 billion, lower than the market expectation of USD 1.753 billion, a decrease of 13.26%[16]. Although earnings per share of USD 2.96 exceeded expectations (+33.94%), the weakness on the revenue side has caused the market to worry about its growth prospects. The company’s net profit has declined for two consecutive quarters, putting pressure on its profitability.

Pinduoduo has continued to launch merchant-friendly policies such as the “100 Billion Support Plan”, squeezing its profit margins. Market competition has shifted from price wars to competition in services and ecosystems, and the industry structure is continuously evolving[17].
