In recent years, as southbound capital flows have continued to expand, the "inclusion effect" has become a core logic for market speculation. During past review cycles, stocks often experienced price increases on their first day of inclusion in the Hong Kong Stock Connect, particularly newly listed IPOs. It became common practice for southbound capital to follow the trend and engage in short-term arbitrage. This phenomenon is closely related to the design of the Stock Connect rules: constituents must meet specific market capitalization and liquidity thresholds for inclusion, and the review schedule is fixed, creating opportunities for capital to position ahead of time and trade based on "inclusion expectations." Historical market performance shows that some stocks, propelled by short-term capital inflows to meet the inclusion criteria, often see a rapid exodus of that capital after inclusion, ultimately leaving southbound retail investors holding the bag. Such price volatility characteristics are relatively common in the Hong Kong Stock Connect market.
On March 9, 2026, the latest quarterly review of the Hong Kong Stock Connect took effect, adding 39 companies (excluding A+H shares) and removing 25. As investor understanding of the speculative logic behind Stock Connect inclusions has deepened, coupled with risk warnings from past speculative episodes, the market overall has become more cautious. The previously common pattern of "soaring on the first inclusion day" has significantly weakened. Some market views suggest that Stock Connect trading has begun to exhibit "left-side" characteristics, where capital speculation is no longer concentrated on the effective inclusion date but shifts earlier to the period between the review cutoff date and the announcement of the constituent list.
ONEROBOTICS is a typical example of this left-side trading. Its case clearly demonstrates how capital can utilize the rules, market themes, and timing differences to complete a full cycle of "pumping and dumping," while southbound retail investors passively become the final buyers.
Timeline Review: A Precise Left-Side Speculation Cycle
Phase 1: A Day-and-a-Half Listing Assessment Period ONEROBOTICS listed on December 30, 2025, with an issue price of HKD 73.8 per share, giving it an initial market capitalization of approximately HKD 17.9 billion. The market quickly recognized that this capitalization level likely met the Stock Connect threshold. According to the rules, newly listed stocks face no minimum listing period requirement; they only need to satisfy liquidity and market cap standards to potentially achieve inclusion in the subsequent quarter. Consequently, ONEROBOTICS required just a day and a half of post-listing trading data to pass the liquidity assessment, clearing the technical hurdle for future inclusion.
Phase 2: Theme Fermentation and Left-Side Rally (January 2026 - February 12, 2026) Market anticipation grew that the stock would be included in the March 2026 Hong Kong Stock Connect review, providing a clear expectation basis for speculation. Simultaneously, the company aligned itself with the high-market-interest robotics sector, branding itself with an "AI Embodied Home Robot" label, which successfully attracted market attention. Although its core revenue remained heavily reliant on smart home products like smart locks and curtain companions—far removed from the core attributes of advanced robotics—the packaging of the "robotics" theme proved highly effective.
Driven by strong inclusion expectations and thematic popularity, capital continuously pushed the stock price higher before the official list announcement—the "left-side" period. By February 12, 2026 (the trading day before Hang Seng Indexes Company announced the quarterly review results), the stock price had surged 167% above its issue price, with its market cap briefly exceeding HKD 44 billion. To maintain momentum, the company announced on February 11 that its products would support OpenClaw Agent, attempting to link into the upcoming positive catalyst.
Phase 3: Realization of Positive Catalyst and Capital Flight (February 13, 2026 - March 8, 2026) On February 13, 2026, Hang Seng Indexes Company announced the quarterly review results, and ONEROBOTICS was included in the Hang Seng Composite SmallCap Index as expected, thereby qualifying for Stock Connect inclusion. With the long-anticipated inclusion catalyst officially realized, the left-side capital that had built positions earlier began concentrated selling. The stock price plummeted 14% on the announcement day, marking the start of a deep correction. The price continued to decline thereafter. By March 8 (the day before formal inclusion), the stock had accumulated a 43% drop from its peak on February 12, with the speculative bubble largely deflated.
Phase 4: Formal Inclusion and Retail Investor Bag-Holding (March 9, 2026 onwards) On March 9, 2026, ONEROBOTICS was formally included in the Hong Kong Stock Connect, allowing southbound retail investors to purchase the shares. However, by this time, the stock price was already fluctuating in a lower range. Lacking fundamental support, the price showed no rebound momentum after inclusion, falling only an additional approximate 5%. The outcome of this speculation was that neither Hong Kong local retail investors who chased the rally during the left-side peak nor mainland southbound investors who attempted to "buy the dip" after formal inclusion could easily profit. The former were deeply trapped before the catalyst materialized, while the latter only gained entry after the price bubble had burst, facing a "no-profit" scenario. Both groups ultimately became the "bag-holders" in this speculation cycle orchestrated by left-side capital.
Following the realization of the inclusion catalyst, weaknesses in the company's fundamentals and the disparity with its thematic packaging became apparent. The full-year 2025 results disclosed on March 24 showed revenue of RMB 901 million, a 47.7% year-on-year increase, but the net loss widened to RMB 24.68 million, surging 702%. Although the company showcased motion and companion robot-related products at the International Consumer Electronics Show in January 2026, actual revenue remained heavily dependent on smart home products packaged as home robots. Planned advanced products like humanoid robots had not yet materialized and could not support the previous valuation premium based on the robotics theme.
More concerning is its inflated valuation. Even after significant price correction, the company's current market capitalization corresponds to a 2025 price-to-sales ratio of 23.4x, far exceeding the 2-4x P/S ratios of comparable A-share smart home companies like Ecovacs and Roborock.
ONEROBOTICS serves as a classic case of left-side trading within the Hong Kong Stock Connect framework. Capital leveraged the short assessment rules of the Connect program, combined with hype around a popular theme, to complete a cycle of pumping and dumping. Meanwhile, small and medium investors, disadvantaged by information asymmetry and passive trading timing, often miss early gains and instead bear the risk of the subsequent price correction.
This phenomenon also indicates that even as the market grows wary of the traditional "inclusion equals rise" playbook, capital can still profit by positioning early on the left side and utilizing thematic packaging. For southbound investors, the core strategy for dealing with such stocks involves caution towards newly listed stocks with short trading histories that qualify based merely on short-term liquidity metrics, avoiding blind following of trendy theme speculation, thoroughly analyzing the company's core business and actual product attributes, rationally assessing valuation reasonableness, and refraining from entering at high levels during the left-side capital speculation phase.
