Singapore Investors Can Now Access More of the AI Boom. But Is SGX the Real Winner?
Singapore investors have another way to participate in the global artificial intelligence boom.
On 16 October 2026, the Singapore Exchange introduced five new Singapore Depository Receipts, or SDRs, tracking TSMC, SK Hynix, Montage Technology, Zhongji Innolight and Z.AI. The additions expand SGX’s SDR offering to 43 counters, giving investors access to a broader selection of overseas-listed companies through Singapore’s market.
The five companies occupy different positions in the AI value chain. TSMC manufactures advanced semiconductors. SK Hynix supplies high-bandwidth memory, an important component in AI computing systems. Montage Technology develops memory-interface chips for AI servers, while Zhongji Innolight operates in high-speed optical interconnects. Z.AI provides exposure to the AI model business.
For investors who want exposure to AI beyond the familiar names listed in the United States, the expanded offering opens another route into the sector.
But there is a more consequential question behind the launch.
Can SGX turn demand for global technology stocks into a lasting competitive advantage for Singapore’s stock market—or will it simply become a convenient venue for trading companies whose economic fortunes are determined elsewhere?
The distinction matters. One outcome would strengthen Singapore’s position as an investment hub. The other could make trading more convenient for retail investors without materially addressing the deeper challenges facing the local equity market.
1. The Real Story Is the Growing Appetite for Overseas Technology Stocks
The launch comes against a backdrop of increasing retail interest in overseas-listed companies.
According to figures cited by SGX, retail investors were net buyers of SDRs totalling S$100 million during the first nine months of 2026. China technology companies accounted for more than 90% of SDR daily turnover and more than 65% of net retail inflows in the third quarter, with Alibaba, Tencent and SMIC among the actively traded names.
These figures suggest that at least part of the opportunity for SGX lies in meeting an existing demand: Singapore-based investors want access to companies and investment themes that are not well represented in the domestic market.
That demand is understandable.
Singapore’s listed market offers exposure to banks, telecommunications, industrials, property and REITs. These businesses can provide income, stability and economic exposure, but they do not collectively offer the same breadth of direct exposure to the global semiconductor and AI supply chain as markets such as Taiwan, South Korea, Hong Kong and the United States.
Investors seeking AI exposure may therefore look overseas.
The question for SGX is whether it can capture more of that activity by making overseas investment simpler.
SDRs offer a potential answer. They allow investors to trade instruments representing interests in foreign-listed securities through Singapore’s market, using Singapore-dollar quotations and the local trading infrastructure.
For investors, this can reduce some of the practical friction associated with accessing overseas markets directly.
For SGX, it creates an opportunity to build a broader product offering around the investment interests of Singapore-based retail investors.
However, attracting trading activity is only the beginning. The more important test is whether investors continue using these products after the initial excitement surrounding their launch fades.
2. The Five New SDRs Offer Exposure to Different Parts of the AI Value Chain
The five additions are interesting because they do not all represent the same AI investment thesis.
They offer exposure to different businesses that may benefit from the expansion of AI infrastructure and applications.
TSMC: The manufacturing foundation
Taiwan Semiconductor Manufacturing Company, or TSMC, is a major manufacturer of advanced semiconductors.
As AI computing requirements expand, demand for advanced chips and sophisticated manufacturing capabilities can create opportunities for companies positioned at the centre of semiconductor production.
But the investment case is not simply that AI demand will increase.
Investors also need to consider the cost of building manufacturing capacity, the capital intensity of the business, customer concentration, technology competition and geopolitical risks surrounding Taiwan.
Even a company with a strong competitive position can disappoint shareholders if its valuation already assumes years of exceptional growth.
SK Hynix: The importance of memory
AI infrastructure requires more than processors.
High-bandwidth memory, or HBM, helps move data between memory and processors at high speeds. It has become an important component in advanced AI computing systems.
SK Hynix offers exposure to this part of the supply chain.
The opportunity is linked to the increasing memory requirements of AI workloads. However, investors should distinguish between structural demand growth and the profitability of supplying that demand.
Semiconductor memory is a cyclical industry. Capacity expansion, changing customer demand and competition can influence pricing and margins.
A company can benefit from a powerful long-term trend while still experiencing periods of earnings volatility.
Montage Technology: The less visible infrastructure layer
Montage Technology develops memory-interface chips used in server platforms, including AI servers.
This illustrates an important feature of the AI investment opportunity: the beneficiaries are not limited to companies that manufacture the main processors or develop AI applications.
As computing systems become more complex, the supporting infrastructure can also become strategically important.
For investors, these less familiar companies may offer a different exposure to AI infrastructure. But understanding the business requires attention to its competitive position, customer relationships, product cycles and valuation rather than simply attaching an AI label to the stock.
Zhongji Innolight: The connectivity challenge
Zhongji Innolight operates in high-speed optical interconnects.
As AI computing infrastructure scales, moving data efficiently between computing components becomes increasingly important. Optical communication products are one part of the broader infrastructure supporting that expansion.
The potential investment opportunity is therefore connected to the physical requirements of increasingly demanding computing systems.
The risk is that investors may extrapolate infrastructure spending too far into the future. Demand expectations, competition, technological change and the pace of customer investment can all influence results.
Z.AI: Exposure to the AI model business
Z.AI offers a different kind of exposure from the semiconductor and infrastructure companies.
Rather than supplying the physical components of AI computing, it represents exposure to the development and commercialisation of AI models.
This distinction matters because the economics of an AI model business can differ significantly from those of a semiconductor manufacturer.
The key questions include whether the company can attract and retain users, develop commercially valuable applications, manage computing costs and turn technological capability into sustainable revenue.
Strong AI capabilities do not automatically translate into attractive shareholder returns.
The broader investment lesson
Together, the five companies illustrate how the AI investment opportunity extends from advanced manufacturing and memory to data transmission and AI models.
But they should not be treated as interchangeable AI bets.
Each has different revenue drivers, competitive pressures, capital requirements, earnings risks and valuation considerations.
The more useful question is not which company has the strongest AI story, but which business can convert AI-related demand into durable earnings and attractive returns on invested capital.
The introduction of an SDR makes a company easier to access. It does not make its underlying business more profitable or its shares more attractively valued.
3. Smaller Trading Sizes Improve Access. They Do Not Make Expensive Stocks Cheap.
One of the practical attractions of the new SDRs is their minimum trading size of less than S$300.
That lowers the amount an investor may need to begin building exposure to some of these overseas companies through SGX.
Smaller denominations can be useful for investors who want to start with a modest position, learn about an unfamiliar company or diversify an existing portfolio without committing a large amount to a single overseas-market transaction.
They can also make it easier to spread a limited investment budget across several companies.
But accessibility and affordability are different concepts.
A stock that can be purchased in a small amount is not necessarily inexpensive relative to its earnings, cash flow or growth prospects.
For example, an investor might find it easier to buy a small position in a high-growth semiconductor company through an SDR. That does not change the price paid for the underlying economic exposure or the risks associated with the business.
There is also a behavioural consideration.
Lower entry costs can encourage investors to explore new markets, but they can also make it easier to accumulate numerous small positions without a coherent portfolio strategy.
An investor who owns several AI-related companies may appear diversified while remaining heavily exposed to the same underlying risk: a slowdown in AI infrastructure spending.
The practical benefit of SDRs is therefore the ability to access a wider range of securities more conveniently. The investment discipline required to select and size those positions remains unchanged.
4. The Hidden Risk: Five AI Stocks Do Not Necessarily Mean Five Independent Bets
The new SDRs cover different parts of the AI value chain. That creates opportunities for investors to diversify across business models.
However, the companies are also linked by a common economic theme: the expansion of AI computing and applications.
That relationship can become a source of risk.
Consider a scenario in which major technology companies continue investing heavily in AI infrastructure. Demand for advanced chips, memory and optical connectivity could remain strong, supporting the revenues of companies supplying those components.
Now consider the opposite scenario.
If technology companies reduce capital expenditure, AI monetisation disappoints, or investors begin questioning the returns on AI infrastructure investment, the impact could extend across several layers of the supply chain.
Chip manufacturers might face weaker orders. Memory suppliers could encounter pricing pressure. Component and connectivity providers might experience slower demand. AI model companies could face greater scrutiny over their costs and ability to generate revenue.
The timing and magnitude of the effects would differ, but the stocks could still decline together.
This is why investors should distinguish between diversifying across companies and diversifying across risks.
Owning companies from several countries does not necessarily provide meaningful protection if their earnings depend on the same investment cycle.
The same principle applies to a portfolio that combines US AI stocks with Asian semiconductor stocks. Geographic diversification may help, but it does not eliminate common exposure to AI spending expectations, technology valuations or shifts in investor sentiment.
For Singapore investors, the new SDRs could expand the available investment universe. Whether they improve portfolio diversification depends on what investors already own and how the new positions fit into their overall exposure.
5. SDRs Could Help SGX Become a Better Investment Gateway. But Trading Volume Is Not the Whole Story.
The strategic case for SGX is straightforward.
Investors increasingly want access to global companies and investment themes. If the exchange can offer a convenient way to trade selected overseas securities, it has a potential route to broaden its appeal beyond traditional Singapore-listed shares.
A larger and more varied product range could encourage investors to return to the platform more frequently. It could also help SGX remain relevant to younger investors and those who are more interested in technology growth than in conventional income-generating securities.
This is particularly relevant when the companies attracting attention are not listed in Singapore.
Yet there is a distinction between creating a useful trading venue and strengthening the wider local equity market.
An investor buying an SDR linked to a foreign company is obtaining exposure to that overseas business. The transaction does not, by itself, mean that the foreign company has raised new equity capital in Singapore or that a Singapore-listed operating company has received additional investment.
The benefit to Singapore’s financial ecosystem depends on the extent to which the product generates sustainable trading activity, supports the market infrastructure and attracts or retains investors.
It is also important to recognise what SDR growth cannot do on its own.
It does not automatically increase the attractiveness of Singapore-listed companies, improve their valuations, create more domestic IPOs or solve the reasons some investors prefer larger overseas markets.
Those are separate challenges.
A successful SDR business could complement efforts to strengthen Singapore’s equity market. But it should not be mistaken for a substitute for a deeper and more competitive domestic market.
The key question is whether SDRs become one component of a broader strategy that makes Singapore more useful to investors—or remain a collection of convenient products with limited influence on the wider market.
6. What Investors Should Understand Before Buying an SDR
Although SDRs provide a way to access foreign-listed securities through Singapore, they are not identical in every respect to holding the underlying shares directly.
Investors should review the disclosure documents for each SDR and understand the structure, costs and conditions that apply.
Several considerations deserve attention.
Underlying share performance
The value of an SDR is linked to the underlying security. If that security falls, the SDR can also decline. Access through Singapore does not remove the investment risks of the overseas company.
Currency exposure
The SDR is traded in Singapore dollars, but the underlying security may be priced in another currency. Exchange-rate movements can affect the value of the investment in Singapore-dollar terms.
Trading liquidity and spreads
The liquidity of an SDR may differ from that of the underlying share. Investors should examine the quoted bid and ask prices, trading activity and the cost of entering or exiting a position. A convenient trading venue is not necessarily the cheapest venue for every transaction.
Trading hours and price movements
The underlying market and SGX operate on different schedules. The underlying share may move while the SDR market is closed, meaning the SDR price may need to adjust when trading resumes.
Fees and conversion arrangements
Investors should check brokerage charges and any fees that may apply to issuance, cancellation or conversion between an SDR and the underlying security. The precise terms depend on the programme.
Rights and corporate actions
The rights associated with an SDR may differ in practice from those associated with holding shares directly. Investors should understand how dividends, corporate actions and any applicable conversion procedures are handled.
These considerations do not negate the convenience of SDRs. They simply mean that investors should compare the full cost and structure of an investment rather than judging it only by its minimum trading size.
For a long-term investor, the relevant question is whether the SDR offers a practical and cost-effective route to the desired exposure.
7. What Should Investors Watch Over the Next 12–24 Months?
The launch itself is a product announcement. Its investment significance will become clearer as investors begin using the new instruments.
Several indicators can help distinguish a lasting development from a short-lived burst of interest.
First, do the new SDRs attract sustained trading?
Initial activity may be driven by curiosity and the attention surrounding AI stocks.
The more important test is whether turnover remains meaningful after the launch period. Persistent activity would suggest that the products are meeting an ongoing investor need.
Second, do bid-ask spreads remain competitive?
Trading volume alone is not enough.
Investors also need to be able to enter and exit positions without excessive transaction costs. Consistent liquidity and competitive spreads would make the products more useful for both smaller and larger investors.
Third, does the investor base broaden?
The existing demand for China technology SDRs provides a starting point.
The next question is whether the new products attract investors who previously did not use SDRs, encourage existing users to become more active, or mainly shift activity between already popular products.
Broader and sustained participation would be a stronger signal than a temporary increase in transactions.
Fourth, does the range expand beyond the most fashionable themes?
AI is an important investment theme, but an investment platform that relies too heavily on a single sector may be vulnerable to changes in market sentiment.
A broader selection of overseas securities could help SGX serve investors with different objectives and risk tolerances. The quality and usefulness of the offering will matter more than the number of products alone.
Fifth, does SDR growth translate into wider benefits for SGX?
Investors assessing SGX itself should look beyond headlines about new products.
Relevant indicators include overall trading activity, the sustainability of product-related revenue, participation across the wider market and progress in making Singapore an attractive venue for companies to raise capital.
These are not interchangeable measures. Strong SDR trading could benefit parts of SGX’s business without necessarily resolving the challenges facing Singapore-listed equities.
That distinction should remain central to any assessment of the exchange’s longer-term prospects.
The Investment Verdict: A Useful New Route Into AI, but Not Yet Proof of a Stronger Singapore Market
The addition of five AI-linked SDRs is a practical development for Singapore investors.
It broadens access to companies operating across advanced semiconductor manufacturing, memory, AI-server components, optical connectivity and AI models. The relatively small minimum trading sizes may also make these exposures more accessible to retail investors.
For investors who want to participate in the AI value chain without opening accounts across several overseas markets, SDRs offer another option worth examining.
But the investment case must still be built company by company.
TSMC’s manufacturing position, SK Hynix’s exposure to memory demand, Montage Technology’s role in server infrastructure, Zhongji Innolight’s connectivity business and Z.AI’s AI-model economics involve different opportunities and risks. None should be bought solely because it belongs to the AI theme.
There is also a bigger question for Singapore.
If SDRs generate sustained trading, attract a broader investor base and contribute to a more useful investment marketplace, they could become a meaningful part of SGX’s evolution.
If activity remains concentrated in a few popular foreign technology names, their contribution to the wider local equity ecosystem may be more limited.
The most important development to watch is therefore not simply how many SDRs SGX lists next.
It is whether investors keep using them—and whether that activity helps make Singapore a more competitive place to invest.
For retail investors, the immediate opportunity is greater choice. For SGX, the longer-term challenge is turning that choice into lasting market relevance.
