SGX Top Gainers Today: Biggest Singapore Stock Market Movers on Dec 12, 2025

SINGAPORE (Dec 12, 2025) — Singapore stocks saw a split personality on Friday: sharp percentage jumps in several thinly traded penny counters, alongside steady gains in heavyweight names such as banks and Hongkong Land, as Asian markets took cues from Wall Street’s post-rate-cut momentum and a softer US dollar. ^[1]

Below is a detailed look at the biggest stock gainers today on the Singapore Exchange (SGX), plus the key corporate headlines, broker calls, and catalysts shaping attention on Dec 12, 2025. All price and ranking data is intraday and based on delayed quotes.

Singapore market snapshot: banks dominate turnover while select names pop on headlines

By mid-session, the most traded counters by value were Singapore’s three local banks — DBS, UOB and OCBC — all higher on the day, alongside active trading in Singtel, Hongkong Land, and Seatrium, based on SGX market data compiled by SGinvestors.io. ^[2]

Regionally, Reuters noted Asian equities were cautiously higher, supported by Wall Street gains after the Fed’s latest cut, even as tech sentiment was dented by a sharp move in Oracle overnight and investors recalibrated expectations for further cuts next year. ^[3]

Biggest SGX gainers by percentage today (intraday, as at ~1:39pm SGT)

The top percentage gainers were led by several low-priced Catalist and small-cap counters, where even a one-tick move can translate into double-digit percentage gains. The following names topped the leaderboard in afternoon trade: ^[4]

Clearbridge Health (SGX: 1H3) — S$0.002, +100% (volume ~257k) ^[5]
CapAllianz (SGX: 594) — S$0.002, +100% (volume ~4.0m) ^[6]
Hoe Leong Corp (SGX: H20) — S$0.002, +100% (volume ~364k) ^[7]
Quantum Healthcare (SGX: V8Y) — S$0.002, +100% (very thin volume ~1k) ^[8]
H2G Green (SGX: 5AI) — S$0.010, +25% (volume ~315k) ^[9]
Meta Health (SGX: 5DX) — S$0.005, +25% (volume ~2.68m) ^[10]
Global Invacom (SGX: QS9) — S$0.054, +14.89% (volume ~20.7m) ^[11]
Lippo Malls Indonesia Retail Trust (SGX: D5IU) — S$0.016, +14.29% (volume ~15.8m) ^[12]
Zico Holdings (SGX: 40W) — S$0.053, +10.42% (volume ~579k) ^[13]
Beverly Wilshire (SGX: 9QX) — S$0.011, +10% (volume ~3.0m) ^[14]
AJJ Medtech (SGX: 584) — S$0.011, +10% (volume ~2.31m) ^[15]

Why this matters for readers: the list above is a pure percentage ranking. It often includes counters where absolute price moves are tiny, and liquidity can be limited, which can amplify both gains and drawdowns.

Most actively traded gainers: where volume was concentrated

If you’re looking for “where the action was” rather than “largest percentage move,” SGX’s top volume and top value lists point to a different set of names.

High-volume gainers (shares traded heavily)

Among the busiest counters by volume were:

Marco Polo Marine — +2.60% on ~70.5m shares ^[16]
Addvalue Technologies — +5.08% on ~56.9 million shares ^[17]
Hiap Seng Industries — +4.76% on ~51.6m shares ^[18]
Global Invacom — +14.89% on ~20.7m shares ^[19]
Lippo Malls Indonesia Retail Trust (LMIRT) — +14.29% on ~15.8m shares ^[20]
Seatrium — +2.88% on ~13.5m shares ^[21]

High-value trading: the institutions’ playing field

By trading value, turnover was led by:

DBS (~S$111.9m, +1.08% )
UOB (~S$97.5m, +1.78%)
OCBC (~S$52.3m, +1.11%) ^[22]

These kinds of flows typically matter more for the Straits Times Index (STI) tone because of the banks’ weight and liquidity.

Biggest blue-chip gainers: who led by absolute price move

Another lens is “top $ gainers” (absolute move), which highlights bigger names where the move is meaningful in dollars/cents, not just percentages.

Key standouts included:

Jardine Matheson — US$69.74, +US$3.09 (+4.64%) ^[23]
Hongkong Land — US$7.14, +US$0.21 (+3.03%) ^[24]
UOB — S$34.89, +S$0.61 (+1.78%) ^[25]
DBS — S$54.98, +S$0.59 (+1.08%) ^[26]
Singtel — S$4.63, +S$0.07 (+1.54%) ^[27]
Sembcorp Industries — S$5.94, +S$0.12 (+2.06%) ^[28]

What’s driving SGX’s top gainers today: the key headlines (Dec 12, 2025)

Not every gainer has an obvious news hook — especially among penny stocks — but several high-profile corporate developments and broker calls stood out on Dec 12.

1) Sembcorp: Alinta deal sparks debate — bullish on earnings, questions on emissions

Sembcorp’s announcement that it will acquire Australia’s utilities provider Alinta Energy (enterprise value A$6.5 billion) put the stock firmly on watchlists. ^[29]

Broker commentary was mixed but active:

Citi Research described the deal as “half-full” (earnings accretion) and “half-empty” (decarbonisation setback), while maintaining a Buy rating and S$7.84 target price. ^[30]
CGS International reiterated an Add call, trimming its target price to S$7.77, noting the market may need time to accept the coal exposure even if the transaction is earnings accretive. ^[31]

This is one of the clearer examples today where a major corporate action plus fresh broker analysis coincided with elevated attention.

2) Seatrium: fresh contract momentum supports sentiment

Seatrium was in focus after it said a Seatrium–GE Vernova consortium won a contract from European transmission operator TenneT to connect North Sea wind power into Germany’s grid, taking its FY2025 new contracts tally to over S$4 billion to date, according to The Business Times. ^[32]

3) Hongkong Land: fund launch progress follows MBFC Tower 3 stake deal headlines

Hongkong Land disclosed “significant advancements” toward launching its first private real estate fund, which it expects to start with more than S$8 billion in AUM. The update came a day after headlines around Keppel REIT’s planned acquisition of Hongkong Land’s stake in Marina Bay Financial Centre (MBFC) Tower 3. ^[33]

In price terms, the counter was also among the top blue-chip movers intraday. ^[34]

4) Singtel: regulatory fine lands as investors weigh longer-term story

Singtel was active after Singapore’s IMDA imposed a S$1 million fine tied to a 2024 voice disruption incident, as reported by The Business Times. ^[35]

Penny-stock spikes: what recent disclosures show (and what they don’t)

For many of today’s largest percentage gainers, the big question is simple: “Is there a news catalyst?” In several cases, the latest SGX disclosures were days or weeks earlier, suggesting price action may be driven more by liquidity dynamics than fresh announcements.

A few examples from company announcement records:

Clearbridge Health: recent disclosures include items such as use of proceeds from a placement (Nov 13) and other corporate updates earlier in November; no Dec 12 announcement appears in the most recent list shown. ^[36]
CapAllianz: recent items include a Dec 10 disclosure of changes in interest of a substantial shareholder, and Dec 8 annual/sustainability report-related releases. ^[37]
Hoe Leong: recent disclosures include additional investment in an indirect wholly-owned subsidiary (Dec 8) and other corporate updates. ^[38]
H2G Green: disclosures on Dec 11 included allotment and issue of new shares pursuant to warrant exercises and changes in substantial shareholders, alongside other updates earlier in December. ^[39]
LMIRT: recent announcements show a rights issue launch (Dec 9) and subsequent related updates (including Dec 10 notes in its announcement list). ^[40]
AJJ Medtech: recent updates include a strategic OEM partnership announcement (Dec 3), plus placement-related disclosures in November. ^[41]

Takeaway: today’s leaderboard mixes (1) headline-driven movers and (2) microcaps where small trades can swing prices. For readers, it’s worth checking volume, spread, and whether a price-sensitive announcement exists before drawing conclusions.

Outlook and what to watch next: rates, research calls, and follow-through

Macro watch: rate-cut expectations remain a key narrative into year-end

Reuters reported the US dollar weakened and markets were pricing at least two rate cuts next year following the Fed’s dovish lean, supporting risk appetite even as tech volatility lingered. ^[42]

For Singapore investors, that macro backdrop can shape positioning in banks (net interest margins vs. loan growth), property developers, and REITs — although day-to-day price leadership will still hinge on stock-specific catalysts.

Broker watch: Singapore property counters upgraded with sizable implied upside

A notable Singapore-specific research catalyst on Dec 12 came from DBS Research, which The Business Times said adopted a bullish stance on Singapore property counters and lifted target prices for developers including CDL, UOL and GuocoLand, implying potential upside of about 28% to 64% from recent traded prices cited in the report. ^[43]

Corporate watch: secondary offerings, rights issues, and share issuance can move prices

As seen in names like H2G Green (warrant-related share issuance) and LMIRT (rights issue process), capital structure events can become short-term catalysts — sometimes bullish, sometimes dilutive, often volatile. ^[44]

Bottom line: today’s “biggest gainers” list is a mix of catalysts and liquidity effects

On Dec 12, 2025, the SGX’s biggest gainers list was topped by multiple 100% movers at ultra-low share prices — but the more broadly followed “market tone” was also supported by strength in major banks and headline-driven names like Hongkong Land, Seatrium and Sembcorp. ^[45]
