Longban Media: A Case Study of “Carnival Ride” Stock Price Volatility – 80 Yuan in Revenue Supports a 93% Gain, a Typical “Concept Bubble” Bursting
Hello everyone, I’m your financial observer. Today we’re talking about a company called Longban Media, whose stock price trajectory was nothing short of a wild “carnival ride”.
In simple terms, it’s the story of a **small business being hyped up into a big story, the stock price soaring to the heavens, only to crash spectacularly in the end.
📌 Key Points Summary
On September 14th, Longban Media’s stock price hit the daily limit down as soon as trading resumed (with very few buyers and a huge number of sellers), closing at 16.8 yuan.
Why such a sharp drop? The reason is that the market had labeled it as an “AI video technology company”, and in just 7 days, its stock price had risen by 6 consecutive daily limits, representing a cumulative increase of over 93%. However, the company itself provided a reality check: its so-called AI video business generated only 80 yuan in revenue in June and 75,000 yuan in July, which accounted for less than 0.01% of the company’s total revenue.
It’s like a supermarket that sells cabbages suddenly claiming to have developed a rocket. Before the rocket was even built, the stock price had already doubled. When people realized the “rocket” was just a model that hadn’t even started construction, the bubble naturally burst.

🔍 In-Depth Analysis: Understanding This “Hype Farce” from Five Perspectives
1. The Absurd “AI Video” Story: 80 Yuan in Revenue vs 93% Gain
This is the most ironic aspect of the entire incident:
- What the market thought: Investors, seeing the buzzword “AI video,” assumed it was the next big trend and bought into it without much scrutiny.
- Company’s actual situation: Longban Media’s main business is publishing, printing, and distribution, which is traditional print media. It did have some involvement with AI video, but on a negligible scale.
- June revenue: 80 yuan (yes, you read that right; probably not even enough for a meal).
- July revenue: 75,000 yuan.
- Percentage of total revenue: less than 0.01%.
- Simple explanation: It’s like a noodle shop owner claiming to be researching quantum computers, but the stock price doubled even though they only bought a calculator. When people realized the “computer” wasn’t even turned on, the bubble burst.
2. Fundamental Weaknesses: Profit Decline of 34%, Yet Exorbitant Valuation
Stock price increases can’t be based solely on hype; we also need to look at whether the company is actually profitable. Longban Media’s fundamentals were quite poor:
- Performance:
- Revenue for the first half of 2026: 659 million yuan, a year-on-year increase of 5.62% (slow growth).
- Net profit attributable to the parent company: 78.678 million yuan, a year-on-year decrease of 34.46% (significant profit shrinkage).
- Both gross and net margins were declining, indicating weakening profitability.
- Valuation comparison:
- Longban Media’s price-earnings ratio (PE): 45.41 times.
- Industry average PE: 17.92 times.
- Gap: Longban Media’s valuation is more than 2.5 times the industry average.
- Simple explanation: The PE ratio indicates how long it would take to recoup the investment. An industry average of 17.92 times means it would take about 18 years to break even. With a valuation of 45 times, the market expects the company to grow significantly in the future. However, given its declining profits, this high valuation is unfounded and represents a “bubble”.
3. The “Small Circulating Stock Pool” Trap: Why Could the Stock Price Rise So Easily?
Many retail investors might ask, “How could a company with declining performance have 6 consecutive daily limits?”
The answer lies in its shareholding structure:
- Key figures:
- Total shares outstanding: approximately 444 million.
- Controlling shareholder and second-largest shareholder hold 79.44% of the shares.
- Remaining external circulating shares: very small.
- Simple explanation: Imagine a pond with 90% of the water blocked by a dam, leaving only 10% available for trading. If a few stones (a small amount of capital) are thrown into that 10%, the water level (stock price) will fluctuate dramatically. Since there are few shares available for trading, a small amount of money can drive the price up. Conversely, if someone wants to sell, the lack of buyers will cause the price to plummet quickly. This is the risk of irrational speculation.
4. Regulatory Intervention and Suspension for Verification: The Market’s “Brake”
When stock prices deviate too far from the company’s fundamentals, regulatory authorities and the company itself will intervene:
- Timeline:
- August 31st–September 7th: 6 consecutive daily limits.
- September 8th: Another 9.12% increase, bringing the total gain to 93.47%.
- September 9th: The company applied for a suspension for verification.
- September 14th: Trading resumed, with the stock price hitting the daily limit down.
- Why the suspension? The stock price increase was severely disconnected from the company’s fundamentals, indicating excessive market enthusiasm and irrational speculation. The suspension was to calm the market and allow investors to see the company’s true value.
- Simple explanation: It’s like a car speeding on the highway; both the traffic police (regulators) and the driver (the company) realized a crash was imminent, so they applied the brakes (the suspension). After the suspension, the stock price had to “correct” its trajectory, which resulted in a drop.
5. Lessons for Ordinary Investors: How to Avoid Becoming a “Sucker”
Longban Media’s case is a typical example of “concept speculation” in the A-share market. Here are some important lessons for investors:
- Be wary of riding on hot trends: If a company’s main business has little to do with a popular concept (such as AI, metaverse, blockchain, etc.), but its stock price soars, be cautious. Ask yourself: Can this concept truly generate real revenue? If not, it’s likely just speculation.
- Focus on fundamentals, not hype: No matter how appealing the story, if it doesn’t translate into profits and cash flow, it’s just an illusion. Pay attention to key indicators like revenue, profit, and margins, not market rumors.
- Be aware of valuations: If a company’s PE ratio is much higher than the industry average without corresponding growth prospects, its stock price may be overvalued.
- High-risk small-cap stocks: Stocks with a small circulating pool are vulnerable to market manipulation and can experience extreme volatility. Investors with limited risk tolerance should be cautious.
- Avoid chasing highs: When a stock hits multiple daily limits in a short period, especially if it’s detached from its fundamentals, the risk of buying at high prices is significant. Once market sentiment turns, the stock price can plummet, potentially leading to a situation where you can’t sell.
📝 Conclusion
Longban Media’s journey from a 93% gain in 7 days to a 99% drop represents the end of an emotionally driven speculation. This case reminds us that in the investment market, rationality is more important than passion, and fundamentals are more reliable than concepts.
For ordinary investors, it’s better to focus on companies with solid performance and reasonable valuations. After all, the stock market is not a casino but a process of discovering value.
