The 2026 A-share “Monster Stock” Craze: A Bubble Game Weaved by Capital, Stories, and Extremely Small Circulation Shares
I. Summary of Key Points
This article reveals an exceptionally strong trend of “monster stocks” in the A-share market from 2025 to early 2026, characterized by consecutive daily price limits and soaring stock prices despite weak fundamental support.
Key Phenomena:
Traditional industry companies, such as “Shangwei New Materials,” saw their stock prices soar several times or even more than ten times within a year due to acquisitions by tech unicorns (like Zhiyuan Robotics) or the introduction of new concepts. Stocks like Fenglong Shares, Baihua Medicine, and Longban Media also experienced consecutive daily price limits.
Key Logic:
1. Shift in Narrative: The market no longer focused on the company's current performance (many were actually losing money) but instead hyped up the potential for “future transformation” (e.g., from chemicals to robotics, from media to AI).
2. Capital Game: Speculative and quantitative funds took advantage of extremely small circulation shares (most shares were held by major shareholders, with only a few available for trading). They used a systematic approach of “igniting the fire, passing the baton, and selling off” to rapidly drive up stock prices.
3. Policy and Context: Regulatory attitudes toward mergers and acquisitions became more favorable, and popular sectors like AI and robotics provided the perfect backdrop for speculation.
Key Risks:
There was a severe disconnect between fundamentals and stock prices (for example, a company with a half-year loss of 167 million yuan had a market value of over 50 billion yuan). Valuations were extremely inflated. With regulatory intervention and the disappearance of favorable factors (such as Zhiyuan Robotics possibly going public on its own), the risk of the bubble bursting was high, and ordinary investors were at great risk of becoming the “suckers” in the scheme.

II. In-Depth Analysis: Understanding the Truth Behind This “Rich-Making Myth” from Five Dimensions
1. Stories Matter More Than Performance: The Valuation Magic from “Resin Selling” to “Robot Manufacturing”
For ordinary investors, the most perplexing aspect is how a chemical company that sells resin could be valued at 90 billion yuan.
Plain Language Explanation:
It’s like a small shop that sells cabbages suddenly being acquired by a top Michelin restaurant. Although the shop is still selling cabbages and may even lose money on renovating its kitchen, what people are buying is the “lottery ticket” that the shop will become a Michelin restaurant in the future.
- Case Study (Shangwei New Materials):
- Past: It was a traditional chemical company with annual profits of tens of millions, a stock price of 7 yuan, and a market value of over 2 billion yuan. This was reasonable given the competitive and slow-growing chemical industry.
- Turning Point: In July 2025, the team behind the robotics company Zhiyuan Robotics announced plans to take control of it.
- Hype Logic: The market immediately imagined a scenario where robots needed lightweight materials, and Shangwei New Materials produced these materials, potentially making it a “robotics concept stock.”
- Result: The valuation logic shifted instantly. Previously, its PE might have been around 10 times; now, as a “robotics tech stock,” it could be valued at 100 times or more. Its stock price soared from 7 yuan to 221 yuan, an increase of over 2800%.
Key Point: Investors were buying into the story of the company potentially making a lot of money in the future, not its current earnings.
2. Extremely Small Circulation Shares: A “Chips Game” Where a Little Can Move a Lot
Another reason these stocks could experience consecutive daily price limits was the small number of shares available for trading.
Plain Language Explanation:
Imagine a neighborhood with only 100 households, 90 of which are owned by the developer (major shareholders), and only 10 are for sale to the public.
- If these 10 houses suddenly become highly sought after, they can be priced very high with minimal investment.
- Due to the scarcity of for-sale houses and high demand, even a small amount of capital can cause significant price fluctuations.
Data Support:
- Shangwei New Materials: Zhiyuan Robotics and other major shareholders held approximately 84% of the shares, with only 16% available for free trading. This meant that a few hundred million yuan could drive the stock price up significantly.
- Comparison: Large-cap stocks like Moutai or banks have huge circulation shares, requiring billions of yuan to move their prices, making such “monster stock” behavior unlikely.
Risk: This structure is very fragile. If the market sentiment changes or major shareholders start selling, the stock price could plummet due to a lack of buyers.
3. Speculative Capital’s “Industrialized” Operations: No Longer Solo Efforts, but a Well-Organized Teamplay
Speculation used to rely on individual investors’ intuition. Now, it’s a well-coordinated effort by professional speculators and quantitative funds.
Plain Language Explanation:
It’s like an organized “pass-the-ball” game, but the participants are professional gamblers and quantitative funds.
- Role Division:
1. Igniters: For example, the Guotai Haitong Nanjing Taiping South Road branch invests tens of millions on the first day to push the stock price to the daily limit, attracting attention.
2. Relay Players: Other speculative firms (like Guosheng Securities Ningbo Sangtian Road) see the limit and buy in, driving the price higher.
3 Harvesters: When the price reaches a high, the initial initiators or those who bought at high prices sell to lock in profits.
- Quantitative Funds: In 2026, the scale of quantitative funds (automatically trading based on algorithms) surpassed that of traditional private equity. They act quickly and strictly, capturing even small price movements, intensifying the speculation.
- Case (Baihua Medicine):
- August 5: Stock A buys 50 million yuan, hitting the daily limit.
- August 6: Stock B buys 28 million yuan, maintaining the limit.
- August 10: Stock A sells 68 million yuan (high-price selling), and Stock C buys in.
- Result: In just a few days, 72% of the circulating shares changed hands. This is not investment but pure chip trading.
Warning: This behavior is highly detrimental to retail investors, who often get caught in the last wave of selling by speculative funds.
4. Policy Support and Industry Trends: Why Now?
Monster stocks don’t appear out of nowhere; they require a specific environment, which in 2025-2026 was created by policy direction and popular industries.
Plain Language Explanation:
- Policy Signals: Previously, regulators were wary of cross-industry mergers (e.g., real estate companies acquiring chip companies). But since 2024, policies have encouraged such acquisitions, giving the market the impression that such “shell swapping” is allowed or even supported.
- Industry Trends: AI and humanoid robots are hot topics. Any traditional company associated with these trends receives significant attention.
- Examples: Tianpu Shares benefited from AI chip-related expectations; Shangwei New Materials from robotics materials; Longban Media from AI video technology.
- Dual Logic: These companies have both a stable “traditional business” base and potential for “emerging concepts,” making them easy targets for speculation.
- Policy Impact: The more inclusive policies lowered the psychological barrier to speculation, and popular industries provided the rationale for it.
5. Precursors to a Bubble Burst: When Stories Can’t Hold Up
All myths must face reality. When performance fails to support stock prices or the underlying stories are disproven, a collapse occurs.
Plain Language Explanation:
Shangwei New Materials is a typical example:
- Reality 1: The company was losing money. The market expected it to become a high-tech company, but its half-year report showed a loss of 167 million yuan.
- Reason: Heavy R&D investment (180 million yuan) without revenue from robot sales.
- Inconsistency: A market value of over 50 billion yuan with a half-year loss of 167 million yuan is unreasonable.
- Reality 2: The initial hype was based on Zhiyuan Robotics acquiring the company for a public listing, but now Zhiyuan Robotics plans to go public on the Hong Kong stock market.
- Logic Crumbles: If Zhiyuan goes public on its own, it no longer needs Shangwei New Materials’ shell, and the “robotics concept” loses its value.
- Reality 3: Regulatory Actions:** The CSRC cracked down on market manipulation and related activities.
- Multiple monster stocks were suspended for investigation and then experienced sharp price drops.
- Stock Price Drop: From a high of 90 billion yuan, the price plummeted to 57.2 billion yuan.
Conclusion:
The essence of monster stocks is the game of “expectation mismatches.” When expectations are fulfilled (e.g., the acquisition fails) or disproven (e.g., the company goes public independently), the bubble bursts.
Advice for Ordinary Investors:
1. Focus on Logic, Not Chart Patterns: If a company’s stock price has increased tenfold but its performance hasn’t changed, ask yourself: Has the company really changed, or is it just the story getting better?
2. Be Cautious of Small-Circulation, Hot-Concept Stocks: These are targets for speculative capital and can be dangerous for retail investors.
3. Avoid Being the Last One in the “Pass-the-Ball” Game: When everyone around you is talking about a particular stock, it’s usually the most risky time.
In Summary:
The 2026 A-share monster stock craze was a capital game fueled by policy support, speculative capital, small circulation shares, and popular concepts. For ordinary investors, understanding the stories is easy, but understanding the capital dynamics is difficult, and knowing when to exit is the most challenging.
