Leadership change at a yellow wine giant: How beginners can investigate

I spent two days trying out methods to check if the leader in yellow wine has changed. This news is worth reading: in the first half of 2026, Kuaiji Mountain had revenue of 853 million yuan, up 4.43% year-over-year; Guyue Longshan had revenue of 787 million yuan, down 11.89% year-over-year. Public reports state this is the first time since listing that Kuaiji Mountain's semi-annual revenue exceeded Guyue Longshan's.

Beginners shouldn't be scared off by the phrase "change of leadership." You only need to understand three terms. Operating revenue is the money the company collects from selling goods. Year-over-year growth compares to the same period last year. Semi-annual means the first half of the year, not the full year. I tried it myself, and judging this doesn't require complex models—two numbers are enough.

Option 1: Check announcements. Slower, but the data source is clean. Open the Announcements section in your market software—this is where companies publish raw reports—and search for "Kuaiji Mountain 2026 Semi-Annual Report." Open the PDF and press Command + F on Mac to search for "Operating Revenue." The report is long, so don't flip page by page. Note the amount and YoY change on the key accounting data page, then do the same for "Guyue Longshan 2026 Semi-Annual Report" and copy the numbers into a Feishu table. My results: Kuaiji Mountain 853 million yuan (+4.43%); Guyue Longshan 787 million yuan (-11.89%). The gap is less than 70 million yuan. Pros: Stable, as announcements are primary sources. Cons: Slow; finding the fields might take over ten minutes the first time.

Option 2: Market App + AI Search. Fast, but must verify. I installed a market app yesterday and used it for quick screening. Search for Kuaiji Mountain's code 601579, enter the stock page. Click "Financials" (or "More" if not visible), expecting to see Total Operating Revenue and YoY Growth. Switch the reporting period to the 2026 Semi-Annual Report; don't stay on the 2025 Annual Report. Then use AI search (asking questions in a chat box) with a query like "Kuaiji Mountain Guyue Longshan 2026 Semi-Annual Operating Revenue Announcement." Let the AI provide the numbers, then go back to the announcement to verify the same field. After using AI search for a while, my feeling is: it's good for locating announcements but not for drawing conclusions directly. In my tests, the summary caught the semi-annual revenue reversal but mixed in 2025 price hike news and sometimes conflated annual and semi-annual figures.

There are pitfalls when checking. Reports mention Guyue Longshan's market cap is 7.5 billion yuan; this is market valuation, not semi-annual sales revenue. Don't confuse market cap with operating revenue. Kuaiji Mountain's lead isn't just about 853m vs 787m; the YoY directions differ too (Kuaiji Mountain +4.43%, Guyue Longshan -11.89%). Trends matter more than single numbers. Price hikes don't equal good sales. Some Guyue Longshan products saw price increases up to 12%, and Kuaiji Mountain also raised prices, but one grew while the other shrank in semi-annual revenue. Pricing actions are just strategies; ultimately, you need to see if goods actually reached consumers.

My conclusion is: it depends. For beginners checking for the first time, I recommend Option 1: manually browse the announcement once to establish correct metrics. For daily monitoring, use Option 2: rough screening via market app, clues via AI search, but always verify against the announcement. Don't let headlines drive you. Next step after learning this: try breaking down mid-to-high-end product revenue for both companies to see if growth is driven by a few expensive wines.
