Small price, big promise — ASX stocks under $1 attract traders chasing asymmetric returns. Many deliver electrifying gains; many also vaporise capital. This guide explains what penny stocks on the ASX are, why they appeal in 2025, where the risks lie, and how to trade or invest in them sensibly. I’ve embedded a curated snapshot watchlist of top-performing ASX penny stocks under $1 in 2025, with short conclusions for each — use the table as a starting point for your own due diligence.
Key Takeaways
- ASX penny stocks (ASX stocks under $1) can produce outsized returns but carry elevated liquidity, corporate and regulatory risks.
- Prioritise fundamentals (FY2025 results, revenue growth, cash runway), liquidity metrics (ADVT, low float) and corporate disclosures (ASX announcements).
- Use strict risk controls: stop-loss placement, position sizing, and an exit plan.
- Keep a rolling watchlist with clear catalysts and update it frequently to capture shifting momentum.
- Treat speculative ASX stocks as a small, deliberate allocation in a diversified portfolio.
What Are ASX Penny Stocks?
Definition of Penny Stocks on the ASX
For practical purposes, penny stocks on the ASX are equities trading below A$1 per share. They often sit in the microcap or low small-cap market-cap bands and typically have:
- Low market capitalization (often < A$200m),
- Low daily trading volume (low float), and
- High sensitivity to discrete news events (exploration results, clinical data, contracts).
There’s no single legal threshold that defines a penny stock on the ASX — the term is descriptive — so when writing or screening, use precise filters: price < A$1, market cap band, ADVT thresholds, and ASX ticker formatting (e.g., ASX:XYZ).
Why These Stocks Trade Under $1
Several common causes:
- Early-stage operations (pre-revenue biotech or exploration juniors),
- Prior dilution or heavy share issuance that compresses per-share value,
- Company distress (weak balance sheet, failed projects), and
- Low liquidity that prevents efficient price discovery.
Understanding the reason under $1 helps you separate speculative gambles from cheap-but-sturdy microcaps.
Why Traders and Investors Are Drawn to ASX Penny Stocks
High Volatility and Growth Potential
Penny stocks can swing 20–100% on single announcements; that volatility generates the “quick gains” traders seek. Catalysts like assay results, licensing deals, or successful trials can re-rate a microcap rapidly.
Speculative Nature of Low-Cap Companies
Microcaps offer concentrated upside: a single successful contract or discovery can radically change outlook. That binary payout profile attracts risk-seeking investors, but it also means many names fail.
Market Trends Driving Penny Stock Popularity in 2025
Drivers in 2025 included renewed interest in battery materials and renewables, biotech microcaps advancing trials, and retail platform growth that makes small-cap trading affordable. Social media and low-commission brokers further increased attention to speculative ASX stocks under $1.
Risks of Trading and Investing in ASX Penny Stocks
Liquidity Concerns
Low float and ADVT (average daily value traded) can create wide bid–ask spreads and slippage. Exiting a position in a low-volume ASX:XYZ stock may move the market against you. Practical rule: define an ADVT threshold (for example, A$50k–A$200k) and size positions accordingly.
Company Fundamentals and Volatility
Many penny stocks lack predictable revenues or cash flows. Dilution via capital raisings is common and can erode shareholder value. Always check FY2025 results and the company’s cash runway.
Regulatory and Market Manipulation Risks
Smaller caps are more vulnerable to pump-and-dump activity and weak corporate governance. Watch for suspiciously timed press releases, concentration of holdings among a few insiders, and sudden social media hype without substance.

Short Conclusions and How to Treat Each Stock
- Kaili Resources (ASX:KLR) — A classic exploration momentum play. The +10,000% figure is dramatic but reflects speculative rerating off early success. Treat as a short-term momentum trade; avoid buy-and-hold unless you can verify a robust resource upgrade and long-term funding plan.
- Chariot Corporation (ASX:CC9) — Extremely small market cap and thin liquidity. Suitable only for nimble traders who can accept large spreads and fast exits. Prioritise stop-loss discipline.
- Argent Biopharma (ASX:RGT) — Typical biotech binary setup: large upside on positive trial/partnership news, large downside on setbacks. Probe the company’s balance sheet and clinical timelines before committing.
- Balkan Mining & Minerals (ASX:BMM) — Commodity-driven performer; if you believe in the underlying commodity cycle, this is a leveraged play. Watch commodity-price correlation and exploration news cadence.
- LTR Pharma (ASX:LTP) — Licensing or clinical progress could re-rate the share price. Funding risk is material; check cash runway and placement terms in ASX announcements.
- Invion (ASX:IVX) — Short-term strength exists, but check for meaningful partnership news or clear catalysts before moving from a trading stake to a longer hold.
- Raptis Group (ASX:RPG) — Turnaround case with strong recent performance. Corporate governance and consistency of the catalysts determine whether momentum is sustainable.
- 3D Energi (ASX:TDO) — Project-development plays need careful timeline management. Position sizes should reflect the risk of project delays.
- Finder Energy (ASX:FDR) — Junior energy plays can outperform in good news cycles; however, low float and thin markets can amplify downside.
- Harmoney (ASX:HMY) — Of the list, more operational resemblance to a small-cap growth business with revenue drivers; still, execution in fintech is key.
- Alfabs Australia (ASX:AAL) — Shows signs of more “fundamental” small-cap strength with FY2025 revenue growth and a first dividend — potentially less speculative than many penny names, but sector cyclicality matters.
- GTN Limited (ASX:GTN) — A relatively defensive microcap in advertising/media with recurring revenue; better for investors who prefer lower event-risk in the penny-stock universe.
Key Sectors for Penny Stock Growth on the ASX
Mining and Resources
Exploration juniors dominate many penny-stock lists. Catalysts include assay results, resource upgrades and commodity cycles.
Biotech and Pharmaceuticals
Biotech microcaps can offer asymmetric returns tied to trial outcomes — high reward, high binary risk.
Technology and Renewable Energy
Small-cap tech and renewable names can scale rapidly with contract wins or funding; in 2025 battery-material and green-energy juniors drew attention.
Strategies for Trading and Investing in Penny Stocks
Momentum Trading Strategies
- Enter on breakout with volume (ADVT > 2× normal), use tight trailing stop-losses, and take partial profits to de-risk.
- Prefer limit orders to control execution in thin markets.
Fundamental Analysis for Penny Stocks
- Prioritise FY2025 results, cash runway (months of funding), insider holdings, and ASX announcements.
- Watch for dilution risk and read placement terms carefully.
Technical Indicators for Small-Cap Shares
- Use VWAP intraday, moving averages (20/50), RSI for momentum, and ATR for stop sizing. Price action must confirm indicator signals.
Portfolio Allocation and Risk Management

- Use fixed-percent risk per trade (0.5–1% of account) and scale positions to ADVT and slippage expectations.
How Penny Stocks Compare to Blue-Chip Stocks
Risk-Reward Ratios
Penny stocks offer higher upside potential but a much higher failure rate. Blue chips provide steadier returns and lower execution risk.

Conclusion: Are ASX Penny Stocks Under $1 Worth the Risk?

Use the watchlist above as a dynamic starting point, but always verify live market data, read ASX announcements, and treat every penny-stock position as an active trade rather than a passive holding.
FAQs About ASX Penny Stocks
Are ASX penny stocks safe for beginners?
No — they’re higher risk and require research, small sizing and emotional control. Start small, demo-trade, and learn position sizing.
What is the difference between a microcap and a penny stock?
A penny stock refers to price (< A$1). A microcap refers to the market-cap band (very small market value). They often overlap but are not identical.
How do I find high-growth ASX stocks under $1?
Use a screener with filters: price < A$1, market cap band, ADVT threshold, FY2025 revenue growth, and upcoming catalysts. Then perform manual due diligence on filings and ASX announcements.
Can penny stocks deliver long-term growth?
Yes — some microcaps become multi-baggers — but the odds are low. Success requires diversification within speculative holdings and careful selection of companies with improving fundamentals.
