Hong Kong Stocks Slide 679 Points at Midday as Alibaba Falls Below HK$100

Hong Kong Selloff Deepens Through the Morning

Hong Kong's Hang Seng Index fell 679 points, or 2.87%, to 22,971 at the midday break on October 22, 2026, slipping below 23,000 as Alibaba, Tencent and Lenovo led a broad retreat. The benchmark briefly touched 22,952.81, almost 700 points below its previous close, with morning turnover reaching HK$127.45 billion.

The Hang Seng Tech Index dropped 4.64% to 3,809, reaching its lowest level in more than two years. Alibaba fell about 6% into the HK$97 range, while Lenovo lost nearly 9% by midday. Battery maker Contemporary Amperex Technology, known as CATL, declined almost 6% in its seventh consecutive session of losses.

The selling extended well beyond technology. Property shares fell more than 2%, while financial and utility shares lost more than 1%. Only one Hang Seng constituent rose, compared with 94 that declined, showing how few large companies escaped the retreat.

Early afternoon trading brought little relief. The Hang Seng was down about 685 points at 22,966, while the technology index traded around 3,807, a decline of roughly 4.7%. The main index had now fallen for three sessions, losing about 1,215 points and passing below both the 24,000 and 23,000 levels during that stretch.

How the Decline Gathered Speed

The market opened lower despite gains on Wall Street the previous night. The Hang Seng began at 23,513, down 138 points or 0.58%, while the technology index opened 1.15% lower at 3,949. Selling then accelerated as the morning progressed.

The sequence shows how an initially modest decline became a much broader retreat:

• October 21: Tencent closed at HK$393.80, below the HK$400 level.
• October 22, market opening: The Hang Seng started at 23,513, with Alibaba down 2.03% and Lenovo down 4.08%.
• By the 10:05 a.m. update: The Hang Seng had touched 23,143, while the technology index was trading around 3,864.
• Later in the morning: The Hang Seng broke below 23,000 and eventually reached 22,952.81.
• Midday and early afternoon: The benchmark stood at 22,971 at the break and around 22,966 shortly after trading resumed.

The midday decline of 2.87% was almost five times the opening percentage loss of 0.58%. For investors, that meant prices were falling throughout the session rather than simply adjusting lower at the opening bell.

Alibaba Accounts for a Large Share of the Damage

Alibaba touched HK$97.45, down as much as 6.03%, taking its shares below HK$100. The intraday low was its weakest price since July 8, and the decline was its largest since August 24.

Alibaba alone pulled the Hang Seng down by more than 100 points. Against the benchmark's midday loss of 679 points, that amounts to more than one seventh of the fall. An index gives different companies different weights, so a sharp decline in a large constituent can move the benchmark much more than a similar drop in a smaller company.

China's State Administration for Market Regulation had convened a meeting urging online shopping platforms to strengthen product quality controls. Alibaba's Taotian business, PDD and JD.com attended. JD.com also weakened, trading at HK$97.90, down 4.67%, in the broader market update.

Alibaba was also facing sustained selling pressure, with trading data indicating five consecutive days of net outflows from major trading accounts. Those flows added to the picture of investors reducing exposure while the company faced closer attention to the quality of goods sold through its platforms.

Tencent's Price Retreat Contrasts With Its Earnings Growth

Tencent fell more than 3% during the morning, extending its decline after closing at HK$393.80 on October 21. Its shares had lost roughly a third of their value since the start of the year and returned to levels near those seen eight years earlier.

The company's business had grown substantially over that period. Revenue rose from 312.7 billion yuan in 2018 to 751.8 billion yuan in 2025. Profit attributable to shareholders increased from 78.7 billion yuan to 224.8 billion yuan.

Those figures put revenue at about 2.4 times its 2018 level and profit at about 2.86 times the earlier figure. The contrast helps explain the pressure on technology shares: a company can earn more money while its shares fall if investors become willing to pay less for each unit of earnings.

That price placed on earnings is often called a valuation multiple. When investors expect slower growth or demand a bigger cushion against uncertainty, the multiple can shrink. Tencent's retreat illustrates how changes in that price can outweigh years of business expansion for shareholders.

Lenovo, CATL and Chip Shares Extend the Technology Rout

Lenovo was the weakest Hang Seng constituent at midday, falling 8.77% to HK$23.72. Its decline later approached 10%, with an early afternoon low of HK$23.42. The company had already opened down 4.08%, making the subsequent selling especially sharp.

Lenovo was also seeking a US$2 billion loan with a term of five years to refinance existing debt, at an interest cost below that of the old borrowing. Its shares nevertheless fell alongside other companies linked to computing and artificial intelligence.

CATL declined nearly 6% after its third quarter results and extended its losing streak to seven sessions. Its opening loss of 3.29% deepened during the morning, placing the battery maker among the largest drags on the market.

Chip shares also weakened. Hua Hong Semiconductor lost more than 7%, while Semiconductor Manufacturing International Corporation touched a low for the past 52 weeks of HK$47.28. The technology index's 4.64% midday fall exceeded the Hang Seng's 2.87% loss by 1.77 percentage points, showing the heavier pressure on that part of the market.

Mainland Investors Continue to Withdraw Money

Mainland investors sold a net HK$3.114 billion of Hong Kong shares through southbound Stock Connect trading in the market update. It was the seventh consecutive session of net selling, bringing the cumulative withdrawal over those sessions to HK$18.512 billion.

Stock Connect allows eligible mainland investors to trade Hong Kong shares through exchanges in Shanghai and Shenzhen. A net outflow means the value of sales exceeded purchases. Seven successive sessions of outflows therefore represented a continuing reduction in exposure through that channel.

The latest net withdrawal was 29.79% smaller than in the previous session, although the direction remained outward. The seven session total was equivalent to an average net withdrawal of about HK$2.64 billion per session.

Southbound purchases and sales together amounted to HK$48.851 billion. The market statistics put their share of Hong Kong turnover at 19.16%, down from 20.01% in the previous session. For a market already under pressure, continued mainland selling removed a potential source of buying support.

The Weakness Reaches Beyond Hong Kong

Mainland China's CSI 300 Index fell more than 1.6% at one point, taking it more than 20% below its closing high on June 22. That crossed the threshold commonly described as a technical bear market.

A bear market describes a decline of at least 20% from a recent peak. In practical terms, an investment tracking such a move would have lost more than one fifth of its value from that peak, before fees or dividends. The CSI 300's retreat showed that the weakness extended across both mainland and Hong Kong shares.

South Korea's Kospi fell more than 2%, while the Kosdaq lost more than 1.5%. Samsung Electronics and SK Hynix weighed on Korean trading, adding to the regional pressure on technology companies.

Mixed earnings from large American companies also fed doubts about the staying power of the rebound in shares linked to artificial intelligence. US stock futures declined during Asian trading, even though the Dow Jones Industrial Average had gained 360 points and the Nasdaq had risen more than 1% in the preceding US session.

A Few Sharp Gainers Stand Out in a Falling Market

BrainAurora Medical Technology, trading under stock code 06681, surged as much as 55% amid interest in policies supporting brain computer interfaces. A later market snapshot put the shares at HK$1.12, up 48.34%.

Brain computer interfaces are technologies that connect signals from the brain with external devices. Interest in that field helped draw buyers even as most large technology companies fell. Digital simulation company 51WORLD, stock code 06651, also attracted attention after its inclusion in NVIDIA's ecosystem.

The wider market remained heavily tilted toward losses. About 55.08% of shares fell, compared with 9.26% that rose, leaving declining shares outnumbering gainers by nearly six to one. Most of the remainder were unchanged.

Midea Group was the sole rising Hang Seng constituent, edging up 0.11% to HK$93.20. Other company news brought steep individual losses: Bloks Group fell 20.95% after its controlling shareholder sold nearly 3.85 million shares for about HK$250 million, while Sands China declined 5.01% after reporting a 12% fall in third quarter adjusted property earnings before interest, taxes, depreciation and amortisation.

What the Broken Market Levels Mean

The Hang Seng's three session loss of about 1,215 points carried it through two round numbers, 24,000 and 23,000, that traders often watch as reference points. Its intraday low took it to its weakest level in roughly four months.

The technology index reached 3,805.54 during the session, its lowest level since September 2024. By midday, 29 of its 30 constituents were down. The breadth of those losses meant investors holding a basket of major Hong Kong technology shares had few rising stocks to offset the declines.

Technical indicators were also described as oversold after the rapid fall. Such indicators compare recent price movements with a chosen historical period. An oversold reading means the decline has been unusually fast or persistent under that calculation; a recovery still requires buyers to return.

The early afternoon prices left both major benchmarks close to their morning lows. The final closing levels for October 22 were not yet available in the trading updates. The immediate picture was of sustained selling across large technology companies, continued withdrawals by mainland investors and weakness spreading across Asian markets.
