In late trading on September 29, the beverage and dairy sector strengthened, with Juneyao Health hitting the daily limit, while Royal Group, Yangyuan Beverage, and Zhuangyuan Pasture also rose. Juneyao Health, whose main business is probiotic health foods and beverages, began to rally around 2:25 p.m., surging straight to the daily limit on several large orders. At 2:24 p.m., the company's official WeChat account published an article about a human clinical study of the J26 Lactobacillus plantarum strain, saying the research had been published in a Nature-affiliated journal and had become the world's first self-developed single strain to complete a randomized controlled trial on weight loss and muscle gain in people with metabolic syndrome. After the intervention, the J26 group showed a significant decrease in fat mass and a significant increase in muscle mass. After the market close, Dazhong Securities News sought confirmation from Juneyao Health's securities department on whether the share price movement was related to the WeChat article. A company staff member said the article was posted by the marketing department and that the timing was indeed coincidental, but that this could not be equated with a definite link between the two. In its 2026 interim report, Juneyao Health described the J26 probiotic as a star strain, but did not disclose sales of related products. The company posted losses for two consecutive years in 2024 and 2025, with cumulative losses of 219 million yuan. In the first half of this year, net profit attributable to the parent company fell 39.74 percent year on year to 4.4991 million yuan. A research note from Guotai Haitong pointed out that the probiotic raw material segment has high added value, with strains being the key to pricing, and that domestic companies' research efforts are expected to promote local substitution.
