Hong Kong Stock Plummets 80% After Inclusion in Southbound Trading, Erasing $2.1 Billion in Market Cap; AI Narrative Fails to Sustain Valuation Bubble

On the morning of May 21, 2026, a dramatic scene unfolded in the Hong Kong stock market. WELLCELL H-NEW (HK:02477), whose share price had surged over 700% year-to-date with a peak static P/E ratio exceeding 1,600 times, experienced a sharp plunge. This occurred less than 20 days after its inclusion in the Stock Connect program, with the intraday decline exceeding 84%. By the market close, the stock was trading at HK$0.83, down 83.16% for the day, with a trading volume reaching HK$4.625 billion. Its total market capitalization plummeted from approximately HK$20 billion before the crash to HK$3.32 billion, evaporating nearly HK$16.7 billion in a single day.

Over the following three trading sessions, WELLCELL H-NEW's share price continued to decline, closing at HK$0.61 today, bringing its total market cap down to HK$2.4 billion.

What is the background of this company?

WELLCELL H-NEW listed on the main board of the Hong Kong Stock Exchange in January 2024. Its core business is telecommunications network services, covering four main segments: wireless network optimization, infrastructure maintenance and engineering, ICT integration services, and related software development. The company's board chairman is the well-known Zhejiang entrepreneur, Qian Fenglei.

In 2025, the company reported operating revenue of RMB 219 million, a year-on-year decrease of 21.46%. Net profit attributable to shareholders was a mere RMB 15.336 million, down 23.85% year-on-year. Net cash flow from operating activities was negative for the second consecutive year, deteriorating further to -RMB 19.788 million in 2025. As of the end of 2025, cash and cash equivalents stood at only about RMB 54.9 million, with basic earnings per share of just RMB 0.015.

This is a traditional telecom service provider facing pressure across revenue, profit, and cash flow, experiencing operational cash outflows for two consecutive years.

A Capital Frenzy Ignited by Inclusion Expectations

The stock's meteoric rise began with the anticipation of Stock Connect eligibility. On March 9, 2026, WELLCELL H-NEW was officially included in the Hang Seng Composite Index due to its involvement in the blockchain payments sector, making it a potential Stock Connect constituent. Subsequently, the Shanghai and Shenzhen Stock Exchanges announced that WELLCELL H-NEW would be formally added to the Stock Connect list of securities on May 6, as the company began trading its subdivided shares.

Catalyzed by this expectation, the company's share price experienced a frenzied rally over two months. Starting from March 10, the price climbed to a high of approximately HK$7.085 on April 20, representing a cumulative increase of 167% during that period. With an extremely scarce free float, a small amount of capital was able to drive significant price increases, completely detaching the stock price from its fundamentals. During this time, the company took advantage of the momentum to implement a 1-for-4 stock split, increasing the total number of issued shares from 1 billion to 4 billion. Following the split, the share price trend reversed sharply, halving in a single day on April 24.

Why Couldn't the AI Narrative Support the Skyrocketing Valuation?

Just one week before the crash, WELLCELL H-NEW had announced a foray into AI computing power, attempting to sustain its high valuation. The company stated it would leverage its existing ICT communication service capabilities to extend its business into three new directions: computing power leasing platforms, computing power scheduling and optimization platforms, and Token aggregation APIs, establishing a dedicated AI strategy task force.

However, computing power leasing is a capital-intensive industry with high demands on cash flow. The feasibility of a company with negative operating cash flow in 2025 and only about RMB 54.9 million in cash on its books trying to compete in this sector was inherently questionable to the market. More critically, by the day before the crash, the company's trailing twelve-month P/E ratio had soared to 1,274.5 times, with a price-to-book ratio of approximately 90.99 times, while its full-year net profit was only RMB 15.336 million. The valuation bubble had long detached from any reasonable range.

In its announcement, the company also admitted that its AI strategic transformation was still in its early stages, with progress subject to multiple uncertainties including technology, market, policy, and operational risks.

Why Does the "Inclusion Leads to Collapse" Pattern Persist?

The crash of WELLCELL H-NEW is not an isolated incident but another classic case of the "inclusion leads to collapse" phenomenon in the Hong Kong stock market. BAOJI PHARMA-B retraced about 87% from its peak within months of being included in Stock Connect. Other newly added Stock Connect constituents like HEALTH 160 and YaoJieAnKang-B also experienced severe price volatility around their inclusion dates.

The underlying logic of this phenomenon is highly consistent: some stocks have an extremely small free float before inclusion, allowing a small amount of capital to generate multi-fold rallies. Upon official inclusion, southbound capital flows in passively, while short-term speculative capital takes profits at elevated levels. The extremely thin liquidity cannot absorb the selling pressure, triggering a cliff-like crash.

Looking at fund flows, despite the stock price crash, southbound capital purchased HK$1.24 billion worth of shares on the day of the plunge. Such high-volume turnover further validates the market behavior pattern of "old capital fleeing, new capital stepping in."

A noteworthy detail is that on May 11—just 10 days before the crash—the company adjusted the use of its raised capital. It reallocated RMB 11 million originally planned for expanding the project management team to RMB 8 million for ICT integration project working capital and RMB 3 million for repaying bank loans. Against the backdrop of continuous cash outflow, this "robbing Peter to pay Paul" maneuver with raised funds objectively heightened market concerns about liquidity pressure.

An Inevitable Valuation Correction

There's an old saying in capital markets: "Speculation can ignore fundamentals, but it cannot ultimately escape them." A traditional telecom network service company with declining revenue and net profit in 2025 and consistently negative cash flow saw its share price skyrocket over 700% in a few months, driven solely by the combination of blockchain and AI narratives and Stock Connect inclusion expectations. Such a rally was, in itself, a classic valuation bubble.

Neither the hasty pivot to AI computing power nor technical maneuvers like stock splits could provide solid support for such a distortedly high valuation. Before the crash, the static P/E ratio had exceeded 1,600 times. After the crash, nearly 84% of the market cap evaporated. Yet, based on this, the valuation of a company with an annual net profit of only RMB 15.336 million still lacks earnings support.

The cliff-like plunge on May 21, while seemingly sudden, was an inevitable valuation reckoning waiting to happen. For both the Stock Connect constituent selection mechanism and investor risk education, the case of WELLCELL H-NEW serves as another reminder to the market: flashy concepts and access qualifications can never replace a company's genuine profitability. When the hype cools and expectations are exhausted, the cost of valuation correction is always borne by those left holding the shares.
