Penny Stocks Singapore
Why Low-Priced SGX Shares Promise Big Returns and Carry Equally Big Risks
A penny stock is a share trading at a very low price — commonly below S$0.20 on SGX — usually issued by a small-capitalisation company with low trading liquidity, limited analyst coverage, and a higher risk profile than established blue-chip stocks.

Key Takeaways
- There’s no official regulatory definition, but on SGX, ‘penny stocks’ generally refers to shares trading below roughly S$0.20, often issued by small-cap companies.
- Penny stocks typically have low market capitalisation, thin trading volume, and wide bid-ask spreads, making them harder and more costly to buy and sell in size.
- A low share price alone does not indicate a cheap valuation — penny stocks can still be expensive relative to earnings or assets, and vice versa for high-priced stocks.
- SGX has specific rules, including the Watch-List mechanism, aimed at companies with persistently low share prices or financial performance, which disproportionately affects penny stock counters.
- Penny stocks are generally considered higher risk and higher volatility than blue chips, and are more susceptible to speculative trading, pump-and-dump schemes, and sudden delisting risk.
What Are Penny Stocks?
A penny stock is typically defined by its low absolute share price rather than any precise, universally agreed threshold. On the Singapore Exchange, shares trading below roughly S$0.20 are commonly described as penny stocks, though this is informal market convention rather than an official SGX classification.
Penny stocks are frequently, though not always, issued by smaller companies — often with limited operating history, thinner profit margins, or businesses still working toward sustainable profitability. Because these companies tend to be smaller, their shares often trade with lower daily volume, meaning fewer buyers and sellers are active at any given time compared to heavily-traded blue chips like the local banks.
It’s important to understand that share price alone says nothing about whether a stock is cheap or expensive in valuation terms. A S$0.10 stock with very few shares outstanding and strong earnings could be undervalued, while a S$0.10 stock with billions of shares outstanding and no profits could be wildly overvalued relative to its underlying business. Valuation requires looking at metrics like market capitalisation, P/E ratio, and balance sheet strength — not just the raw share price.
How Does It Work in Singapore?
SGX has mechanisms specifically aimed at monitoring and flagging companies with financial difficulties, which disproportionately affects penny stock counters. The SGX Watch-List, for instance, captures Mainboard-listed companies that fail certain financial criteria, such as sustained pre-tax losses over several consecutive years combined with a low average daily market capitalisation — companies placed on this list face a timeline to meet exit criteria or risk delisting.
Singapore investors trading penny stocks should also be aware of SGX’s minimum trading price (MTP) framework, introduced in past years specifically to discourage excessively low-priced, thinly-traded Mainboard counters, requiring certain companies to maintain a share price above a defined threshold or face consequences including potential transfer to the Catalist board or delisting.
| Feature | Penny Stocks | Blue Chip Stocks |

| Liquidity | Often thin, wide bid-ask spreads | Generally deep and tight spreads |
| Analyst coverage | Often limited or none | Usually extensive |
| Volatility | Generally higher | Generally lower |

Worked Example
A Singapore investor is drawn to a small-cap SGX stock trading at S$0.08 per share, reasoning that it ‘can’t fall much further’ and has significant upside if it merely doubles to S$0.16. She buys a board lot of 1,000 shares for S$80.
However, she discovers the stock trades only a few hundred thousand shares a day with a wide bid-ask spread — the best bid is S$0.075 and the best offer is S$0.085, meaning she effectively loses a meaningful percentage instantly on the spread alone if she needed to sell immediately. The company also has thin analyst coverage, making it harder to independently verify whether S$0.08 reflects genuine undervaluation or a justified discount for weak fundamentals — a risk that’s harder to assess than with a well-covered blue chip.
Advantages
Lower absolute capital required. A board lot of penny stocks can cost a fraction of a board lot of blue chips, letting investors with smaller capital participate in more companies or diversify more granularly.
Potential for large percentage gains. Smaller companies have more theoretical room to grow multiples of their current size compared to already-large blue chips, which can translate into outsized percentage returns if the business succeeds.
Access to emerging or niche businesses. Penny stocks sometimes represent early-stage or niche companies not yet covered by mainstream analysts, offering exposure to ideas before they become widely known.
Risks and Limitations
Wide bid-ask spreads erode returns. Thin trading liquidity means the gap between buying and selling price can be a significant percentage of the stock’s value, making round-trip trading costly.
Higher fraud and manipulation risk. Low-priced, thinly-traded stocks are more susceptible to pump-and-dump schemes, where a stock is artificially hyped to attract buyers before early holders sell into the rally.
Limited financial transparency. Smaller companies often have less analyst coverage and sometimes less robust financial reporting scrutiny, making it harder to independently verify a company’s true financial health.
Delisting and Watch-List risk. Persistently underperforming penny stock companies risk being placed on SGX’s Watch-List or facing delisting, which can result in a sudden, severe loss of liquidity or value for shareholders.
Comparison Table
| Factor | Penny Stocks | Blue Chip Stocks |
|---|---|---|
| Capital required per board lot | Often under S$500 | Often S$1,000+ |
| Liquidity risk | High | Low |
| Volatility | High | Lower, relatively stable |
| Information availability | Often limited | Extensive |
| Suitable for | Experienced, risk-tolerant investors | Most investors, including beginners |
The Bottom Line
For Singapore investors, penny stocks can offer an accessible entry point and theoretical upside, but the combination of thin liquidity, limited information, and elevated fraud risk means they demand significantly more due diligence and risk tolerance than blue-chip investing. They’re best treated as a small, speculative allocation rather than a core portfolio holding.
