Investors are well aware of the advice to “invest for the long term”.
However, the “long-term” can be very far off, and it’s tough to imagine the benefits you will receive for your patience.
Hence, the best way to illustrate the power of long-term investing is to zero in on several stocks that have delivered solid returns to their investors over time.
This rare bunch of stocks has multiplied their investors’ wealth many times over and continues to possess solid catalysts for the future.
Here are four Singapore stocks that delivered impressive returns over the last five years.
Oiltek International (SGX: HQU)
The first stock on this list is Oiltek International, a company that provides a comprehensive and diversified range of refinery processes and engineering solutions across different sectors of the vegetable oils industry value chain.
With more than 44 years of operating history under its belt, Oiltek has successfully designed, built, and commercialised plants in more than 35 countries across five continents.
Over the past five years, Oiltek’s share price has soared 837% to close at its all-time high of S$0.76 recently.
The group reported record highs for both its revenue and net profit for 2024.
Revenue rose 14.5% year on year to RM 230.3 million while net profit surged 55% year on year to RM 29.6 million.
The business declared a final dividend of S$0.018, taking its total 2024 dividend to S$0.027.
For the first quarter of 2025 (1Q 2025), Oiltek reported a mixed result.
Revenue dipped 5.1% year on year to RM 46.7 million, but net profit climbed 22.1% year on year to RM 5.4 million.
Management remains confident about the long-term outlook for the edible and non-edible oil refinery segment.
Imarc Group, a market research and consulting firm, projects that the global fats and oils market is expected to reach US$336.3 billion by 2033, growing at 3.4% per annum from 2025 to 2033.
Azeus Systems (SGX: BBW)

Azeus declared a final dividend of HK$3.90, taking the total FY2025 dividend to HK$5.50 per share.
Revenue was driven higher by the continued growth of Azeus’ Products business line, and also from contributions from the Central Electronic Record-Keeping System (CERKS) contract in Hong Kong.
The remaining revenue from CERKS will be recognised over FY2026 and FY2027, and the group also plans to broaden its geographic reach and continue investing in the development of its ESG reporting platform.
