Record HK Stock Buyback Wave: Companies 'Buy the Dip' in Unison, Signaling Confidence – Is the Golden Window for Trading HK Stocks Here?

On July 29, 2026, HKEX data showed that July buybacks by HK-listed firms had surpassed HK$30 billion, the highest monthly total this year. Tencent, AIA, HSBC and other blue chips made massive repurchases, creating a rare "collective buying" scene. Market analysts believe this not only reflects strong displeasure among HK companies with their undervalued shares, but also sends a clear confidence signal to the market—the bottom for HK stocks may be near. For investors, the current situation offers the best answer to "Why invest in HK stocks?": low valuations, heavy buybacks, and capital inflows converge, presenting an opportunity.

1. Buyback Data: Blue Chips Lead, Record Amount

As of July 29, July 2026 HK stock buybacks hit HK$31.5 billion, surpassing the previous high of HK$28.7 billion in December 2025. Tencent led with HK$8 billion in a single month, followed by AIA with HK$5.8 billion. HSBC, China Mobile, and Alibaba each exceeded HK$2 billion. By sector, tech, finance, and consumer companies were most active. Notably, Tencent has conducted buybacks for 18 consecutive trading days, cumulatively over HK$12 billion, a record for the company.

2. Behind the Buybacks: Why Are Companies 'Buying Themselves' Now?

Large-scale buybacks by HK-listed companies are typically driven by several factors:

• Severely Undervalued Stocks: The Hang Seng Index's latest P/E is only 9.8x, near a decade low and far below the S&P 500's 22x and Shanghai Composite's 14x. Many quality companies trade below book value, prompting management to see buybacks as the best way to reward shareholders.
• Ample Cash Flow: Internet giants like Tencent and Alibaba have slowed capital spending, generating ample free cash flow. Buybacks are more flexible than dividends and directly boost earnings per share.
• Hedging Performance Pressure: Some companies facing growth slowdowns use buybacks to stabilize stock prices and boost investor confidence.

3. Implications for Investors: What Does This Buyback Wave Mean?

Historical data shows that HK stock buyback waves often appear near market bottoms. After buyback peaks in early 2016, March 2020, and October 2022, the Hang Seng Index saw significant rebounds. Current buyback totals account for over 3% of total HK stock turnover, approaching a "precise bottom-fishing" signal. In addition, southbound capital is also increasing positions: net purchases via Stock Connect exceeded HK$40 billion in July, in line with buyback direction.

How Can Investors Seize the Opportunity?

For cross-border investors, especially those in Thailand, participation is possible through Stock Connect or HK stock ETFs. Data from the Siam ETF Platform shows significant inflows into Tracker Fund of Hong Kong (2800.HK) and Hang Seng Tech ETF (3032.HK) in July. Compared to A-shares, HK stocks offer more flexible trading rules (no price limits, T+0), a wider variety of products (derivatives, REITs, etc.), and a clear valuation discount, making them an ideal choice to diversify A-share risk.

4. Risk Note: Buyback Wave ≠ Immediate Upside

While buybacks send positive signals, investors must remain cautious about external uncertainties such as the final stages of Fed rate hikes and geopolitical risks. Completion of buybacks does not guarantee immediate price appreciation; there have been historical cases where prices continued to fall after buybacks. We recommend phased or dollar-cost averaging strategies, focusing on leading companies with sustained buyback efforts and solid fundamentals.

5. Conclusion: Reasons to Trade HK Stocks Are Growing

From valuation and corporate behavior perspectives, HK stocks are in a rare "discount season" seen once in many years. Collective buybacks by listed companies represent the most direct value statement, while sustained southbound capital inflows confirm consensus among domestic and foreign investors. For investors seeking long-term returns, consider gradually building positions in the HK stock "value trap" via ETFs or quality stocks. Siam ETF will continue to track HK stock dynamics, providing diversified cross-border investment tools.
