To The Moon

🌟🌟🌟Uncle Sam meets Singapore's Merlion!  The unstoppable march of the SGX Singapore Depository Receipts (SDR) framework has just crossed its most exciting frontier yet.   In July 2026, SGX launched an initial batch of 3 US linked SDRs (Grab, Sea Ltd and SpaceX).  On 16 October, SGX recently added 5 new international/US listed ADR tracking counters.  These include TSMC and SK Hynix.

Imagine tracking some of the most high growth companies in the world during your morning coffee at a local kopitiam, trading them entirely in Singapore Dollars with zero foreign exchange transaction worry.  Your Tiger Brokers Account has just gotten an elite American passport.

But here is the real kicker: the barrier to entry has been absolutely obliterated.  While the standard board lot size for Asian SDRs sits at 100 units, SGX intentionally launched this premium US listed line up with a minimum board lot size of just 10 units.

Welcome to Koolgal's Investing 101 : SDRs series with today's spotlight on 5 US SDRs.  Are they actually good buys?

1.  $Grab US SDR 2to1(UGBD.SI)$ - The Regional Utility King 

Grab is no longer a simple,  cash burning ride hailing app.  It is the indispensable operating system for Southeast Asian daily life.  Crucially Grab has turned its massive ecosystem into a financial juggernaut through the GXS Bank (the Grab money app).  By offering high yield, friction free daily interest savings pocket right inside the app, Grab has captured millions in sticky local deposits.

Now that Grab has successfully shifted to net profitability and huge free cash flow generation, Grab is a defensive compounder.  With a tiny 2:1 ratio and a 10 unit lot minimum, this Grab SDR lets you own a massive regional monopoly with almost zero capital barrier to entry.

2.  $Sea US SDR 50to1(UGGD.SI)$ - The Digital Conglomerate Rocket

SEA Ltd is the reigning monarch of regional e-Commerce via Shopee and digital entertainment through Garena.  But SEA's real secret weapon is MariBank (the SEA money app).  MariBank has taken Singapore by storm by seamlessly integrating digital banking into the Shopee ecosystem, allowing users to save, invest and pay with incredible ease.

Shopee has effectively crushed the competition and achieved sustained operating profitability together with this booming FinTech arm.

With the 50:1 conversion ratio, you get fractionalised access to a tech giant, letting you accumulate it steadily in affordable tranches.

3. $SpaceX US SDR 100to1(UXSD.SI)$ - The Frontier Monopoly 

SpaceX is the undisputed crown jewel of the latest SDR lineup.  It has just posted an astronomical USD 4.4 billion profit on a 161% revenue spike.  Between SpaceX's Starlink global internet empire and its newly launched Superintelligence AI compute division, SpaceX is combining the physical and digital infrastructure of the next century.

This 100:1 ratio SDR is one of the very few public vehicles on Earth allowing Singapore retail investors to capture space exploration upside potential right in their local account.

4.  $TSMC US SDR 300to1(UTSD.SI)$ - The Global Gatekeeper 

Taiwan Semiconductor Manufacturing Co. (TSMC) is the literal oxygen of the modern technology world.  TSMC manufactures nearly 90% of the world's most advanced processors.  This means NVIDIA, Apple and AMD cannot exist without them.

As the AI revolution accelerates, TSMC holds unmatched pricing power.  The 300:1 ratio turns a high priced global tech bottleneck into a highly accessible local buy.

5.  $SK Hynix US SDR 100to1(UNXD.SI)$ - The High Bandwidth Memory (HBM) Monopoly 

If TSMC is the engine of AI, SK Hynix is the specialised fuel tank.  SK Hynix is the market leader in HBM, the critical chips required to power NVIDIA's AI data centers.

Demand for HBM is vastly outpacing supply, guaranteeing SK Hynix staggering profit margins for years to come.

This SDR  100:1 ratio gives you direct, localised exposure to the infrastructure backbone of the global AI boom.

The Catch: Mind the Local Volume Gaps 

While the fundamental metrics of these 5 US SDRs are solid, it is important to know that local trading volumes are still developing as they are new to SGX.

The order book is less liquid than the massive round-the- clock volume found on the Nasdaq or NYSE.  This means bid to ask spreads can widen.  If you are a fast moving day trader looking for split second razor thin execution, you might find the local market a little sticky.

However if you are a long term accumulator, this low volume period is actually your best friend.  It allows you to quietly build positions without chasing artificial high frequency price spikes.
