A bull market is a sustained period in which stock prices rise over an extended time, usually supported by economic growth, improving corporate earnings and positive investor sentiment.
The Straits Times Index (STI) reached an intraday record high of 5,561.42 points on 15 July 2026 (CNBC), a level that signals strong confidence but also raises the risk of investors overpaying near a peak.
This bull market in Singapore has lifted blue chips including DBS Group, Singapore Technologies Engineering and Sheng Siong to record highs in recent months. Rising markets create opportunities to grow wealth, but they reward discipline.
For those who invest in Singapore, this guide sets out how long-term investors approach the stock market in Singapore while managing risk, and how to keep their investments in Singapore aligned with long-term goals.
Key takeaways
- Focus on business fundamentals rather than short-term noise, because bull markets encourage costly emotional decisions.
- Stay committed to long-term goals; a consistent strategy outperforms attempts to time the market.
- Keep a liquid emergency fund and avoid investing money you will need within a few years.
- Diversify across industries, asset classes and markets to reduce concentration risk.
- Review your asset allocation periodically to maintain your portfolio’s intended level of risk.
What is the difference between bull market vs bear market?
A bull market and a bear market describe opposite phases of the same market cycle. A bull market is a sustained period in which stock prices rise, usually supported by economic growth, improving corporate earnings and positive investor sentiment. A bear market is the reverse, a prolonged decline in which prices fall, commonly defined as a drop of 20% or more from recent highs, driven by weakening economies, falling profits or negative sentiment.
The stock market in Singapore moves through both phases, and the Straits Times Index (STI) is the benchmark investors watch to gauge which phase the market is in.
Long-term investors in Singapore treat both phases as normal stages of the cycle rather than signals to abandon a strategy. Recognising which phase the market occupies helps investors manage risk, but neither phase justifies emotional decisions that work against long-term goals.
Why can the bull market in Singapore be dangerous?
A bull market rewards investors, but the same rising prices that build wealth also encourage poor decisions. Four behaviours drive the risk:
- Overconfidence, as investors read strong performance as certainty.
- Chasing high-performing stocks without understanding the underlying business.
- Ignoring warning signs because recent results look attractive.
- Buying “winning” stocks late, once optimism is already priced in.
Markets move in cycles, and periods of growth are often followed by corrections. Long-term investors in Singapore therefore avoid decisions driven by excitement or fear of missing out (FOMO), and stay anchored to their financial goals.
1. Focus on business fundamentals, not headlines
Headlines amplify record highs and trending stocks, creating the impression that a rising share price will keep climbing. This drives FOMO. Investors counter it by evaluating four financial fundamentals:
- Revenue growth: Signals market demand and the ability to capture share. Consistent growth indicates the business sells products the market needs.
- Profit margins: High or expanding margins reflect pricing power, operational efficiency and cost discipline.
- Debt levels: Excessive debt raises interest expense, constrains expansion and increases bankruptcy risk during downturns.
- Free cash flow: Shows the flexibility to repay debt, fund growth or return capital to shareholders.
Buying purely because a stock has recently performed well exposes investors to unnecessary risk if sentiment shifts. Prioritising fundamentals over sentiment identifies companies that keep creating value after the current bull market ends.
2. Stay focused on your long-term goals
Bull markets pull attention towards short-term gains. Checking prices constantly or reacting to daily movements produces impulsive decisions that work against your objectives.
Define why you invest, retirement in 20 years, or a home purchase in five to ten years, and let that horizon govern your actions. Successful investing rarely depends on one perfect trade; it depends on consistently following a strategy that serves long-term goals. Review your financial plan periodically, but avoid frequent changes based on short-term sentiment, which undermine returns and interrupt compounding.
3. Invest regularly
Many investors hesitate to buy at record highs, fearing a correction. However, all-time highs do not signal an imminent decline. Historically, many bull markets have continued setting new highs as economies expanded, profits grew and innovation strengthened. Waiting for the “perfect” entry point costs opportunity.
Amazon illustrates the point. On a split-adjusted basis, an Amazon share climbed through levels that each looked expensive at the time. The four charts below mark successive entry points an investor might have hesitated at, each drawn from the same 11-year price history.

Source: fiscal.ai, as of 27 July 2026. Amazon (AMZN) traded at about US$228 at the turn of 2025.
Each of these levels looked high at the time, yet the stock kept climbing. An Amazon share traded at about US$65 in early 2018, roughly US$95 at the start of 2020, about US$152 at the start of 2024 and around US$228 at the start of 2025.
As of 27 July 2026, Amazon trades at approximately US$235, a total gain of 773.6% (a compound annual growth rate of 21.8%) over the 11 years to 26 July 2026. An investor who hesitated in early 2018 because the stock “looked high” at around US$65 would still have more than tripled their money by staying invested.
Dollar-cost averaging (DCA) enforces this discipline. You invest a fixed amount at regular intervals regardless of market conditions, spreading purchases across different price levels. Investing consistently through both rising and falling markets grows wealth over time.

4. Diversify carefully
A bull market does not lift every investment equally. Some sectors or markets outperform while others lag, so a portfolio weighted only towards sg stocks carries avoidable risk. Diversifying beyond Singapore stocks across industries, asset classes and global markets reduces concentration risk and prevents overdependence on a few high performers, whether those are stocks in Singapore or overseas. Strong markets also create a chance to review underperformers, but a stock that has lagged is not necessarily a poor long-term holding. Rather than selling on weakness alone, assess whether the business outlook remains intact and whether the investment still serves your goals.

5. Review your assets periodically
A bull market gradually unbalances a portfolio. As certain sectors outperform, they occupy a larger share than intended, which lifts returns during the rally but raises risk if conditions change. An overweight position in one sector or asset class can produce larger-than-expected losses. Reviewing your asset allocation periodically maintains your intended risk level. Rebalancing means trimming holdings that have grown beyond target and adding to those that have become underweight. Reducing winners feels counterintuitive, but it protects portfolio integrity and keeps investments aligned with long-term goals.

6. Maintain a safety net
Even in a strong bull market, an adequate emergency fund matters. Job loss or medical costs arrive without warning, and cash set aside reduces the need to sell investments during unfavourable periods. Treat investing as a long-term commitment, not a source of ready cash. Money needed within the next few years belongs in lower-risk savings rather than the stock market. Separating emergency savings from your investment portfolio gives investments time to grow and removes pressure to make emotional decisions when markets turn volatile.
Tread carefully, even during bull markets
Bull markets test discipline. Rising prices create confidence that encourages chasing trendy stocks, taking excessive risk or abandoning a sound strategy. These behaviours can look profitable briefly, then expose investors to risk when conditions change. Consistent investors, those who hold their approach through every stage of the cycle, build the foundation for financial success that outlasts any single bull market.

Frequently asked questions
What is a bull market in Singapore?
A bull market in Singapore is a sustained period in which local stock prices rise over an extended time, typically supported by economic growth, improving corporate earnings and positive investor sentiment. It is often measured by the Straits Times Index (STI), the benchmark of the 30 largest Singapore-listed companies. The STI reached an intraday record high of 5,561.42 points on 15 July 2026, reflecting the current bull market.
Should I continue investing when the stock market in Singapore is at an all-time high?
Yes. Market highs do not necessarily mean a correction is near. Historically, markets have continued reaching new highs over long periods, so staying invested for the long run remains the sound approach.
Should I rebalance my portfolio during a bull market?
Yes. A strong rally can make certain stocks a much larger portion of your portfolio, raising overall risk. Rebalancing restores your target asset allocation and keeps your strategy aligned with long-term goals.
How do I know if a stock is overvalued during a bull market?
Assess whether the company’s earnings growth supports its valuation rather than focusing on recent price gains. Comparing valuation metrics against historical levels, industry peers and future growth prospects indicates whether the price is reasonable.
Why does diversification still matter in a bull market?
Different sectors and markets perform differently across the economic cycle. Diversification reduces concentration risk and prevents overdependence on a small number of investments.
Should I invest all my spare cash during a bull market?
No. Maintain an emergency fund first, and invest only money you will not need in the short term, so you are never forced to sell during a downturn.
