Singapore celebrates its 60th birthday this year. In six decades, our nation has transformed from a small trading port into a global financial and industrial hub.Our stock market has grown alongside the economy, rewarding patient investors with both capital gains and consistent dividends.With the Straits Times Index (SGX: ^STI) near record levels, it is worth taking a closer look at which Singapore stocks have stood out over the past decade and what they can teach us about long-term investing.

The STI Over the Past Decade

Over the past decade, the Straits Times Index, measured by the STI ETF (SGX: ES3) on a total return basis, climbed more than 84% from July 2015 to July 2025. That works out to about 6.3% a year with dividends reinvested.But the real standouts were the top 10 STI constituents. These delivered annualised returns ranging from 9.1% to an impressive 20%, with many leaving the index far behind.

Rank	Company	Ticker	10-Year CAGR (Total Return)
1	Yangzijiang Shipbuilding (Holdings) Ltd	SGX:BS6	20.0%
2	Sembcorp Industries Ltd	SGX:U96	18.3%
3	DBS Group Holdings Ltd	SGX:D05	16.1%
4	Singapore Technologies Engineering Ltd	SGX:S63	15.2%
5	Singapore Exchange Ltd	SGX:S68	11.8%
6	Keppel Ltd	SGX:BN4	10.4%
7	Oversea Chinese Banking Corporation Ltd	SGX:O39	10.2%
8	United Overseas Bank Ltd	SGX:U11	10.2%
9	Venture Corporation Ltd	SGX:V03	9.8%
10	Mapletree Industrial Trust	SGX:ME8U	9.1%

What These Winners Have in Common

1. Durable businessesSingapore Technologies Engineering thrives on long-term defence and engineering contracts with both government and commercial clients.  The three major banks, DBS, OCBC, and UOB, dominate local banking and continue tapping into ASEAN growth. Mapletree Industrial Trust combines the stability of Singapore’s industrial real estate with growth from overseas data centres.2. Dividends as a core value componentFor many of these stocks, dividends made up a significant portion of total returns. Singapore Exchange is a prime example as its steady dividend payouts have been a key driver of investor gains.3. Geographic diversificationSeveral of these companies earn substantial revenue outside Singapore. Yangzijiang Shipbuilding serves global clients in a cyclical industry, meaning earnings and dividends can swing with global trade cycles. Venture Corporation and the banks also generate meaningful income from regional operations.

Why These Returns Matter

Even steady sounding returns can turn into meaningful wealth over a decade.

• S$10,000 invested in ST Engineering in 2015 would be worth about S$41,300 today, based on its total return CAGR of 15.2% with dividends.
  
• S$10,000 in DBS over the same period would have grown to roughly S$44,500, reflecting its total return CAGR of 16.1%.

This is the power of compounding. Holding quality companies for the long term allows both price appreciation and dividends to work together.

Which Ones Still Look Wise Today?

Not all of yesterday’s winners will deliver the same results in the decade ahead. For some, future returns will depend on their ability to grow earnings from here. Others operate in industries where earnings can be more cyclical, making results less predictable.On the other hand, companies such as ST Engineering, DBS, OCBC, UOB, and Mapletree Industrial Trust continue to stand out for their steady dividends, resilient business models, and clear role in Singapore’s economic landscape. These qualities can help them remain attractive holdings for long-term, income-focused investors.

Lessons for Investors

1. Long-term ownership works
The best performers here were not speculative darlings. They delivered solid results year after year, letting compounding do the heavy lifting.2. Dividends cushion market volatility
Even in difficult years, dividends provided tangible returns that kept investors invested.3. Quality over quantity
You do not need to own every STI stock. A focused portfolio of enduring businesses can deliver strong, sustainable performance.
