China Stock of the Day | Kabutaro & Friends

Jilin University Zhengyuan Information Technologies <003029>, an information security company built around cryptography, was the Chinese stock most talked about online on October 19, 2026.
Background: On October 19, the stock hit its daily limit right after the open, following limit-ups on October 15 and 16 for a third consecutive limit-up, the longest streak in the market that day. The market had focused on it as a play on AI security, post-quantum cryptography, and the low-altitude economy. In a stock price abnormal fluctuation announcement on the night of October 18, the company explained that although it has technology for AI security and post-quantum products, the related business accounts for a small share of revenue and has not produced revenue at scale, and that its low-altitude economy business also has little impact on results. The turnover rate on October 16 was 21.01%, its trailing P/E ratio was minus 33.83 times (industry average 62.03 times), and it warned of possible irrational speculation. In the first half of 2026, revenue fell 19.41% year on year, with a net loss of 35.1 million yuan. Its third-quarter report is scheduled for October 29.
