How to Invest in Australian Small Companies

By Roopon Team7 min read

What Are Australian Small Companies and Why Do They Matter?

The Australian share market is dominated by large-cap companies in banking, mining, and retail. But below the ASX 100, a much larger and more diverse universe of smaller businesses offers distinct investment characteristics.

  • Market cap definitions on the ASX: Large-cap (ASX 50 or 100) companies are the household names - CBA, BHP, CSL. Mid-cap covers ASX 100–300. Small-cap is typically ASX 300+ with market capitalisation under $2 billion. Micro-cap falls below $300 million
  • The small-cap premium: Academic finance research (Fama-French three-factor model) documents a historical 'size premium' - smaller companies have delivered higher long-term returns than large companies, partly as compensation for lower liquidity and higher business risk
  • Australian small-cap diversity: Where the ASX 200 is dominated by banks and miners, the ASX small-cap universe includes technology, healthcare, emerging resources, consumer discretionary, and industrials - offering genuine sector diversification not available in large-cap indices
  • Less analyst coverage: Small companies receive less coverage from institutional brokers - creating information inefficiency that skilled investors can exploit. Prices may diverge more from intrinsic value than in highly covered large-caps
  • Higher individual company risk: Small companies have less financial resilience - a single product failure, regulatory setback, or management change can devastate a small-cap share price. Diversification is more critical in small-cap portfolios than in large-cap
  • Liquidity constraints: Small-cap shares trade in lower volumes - buying or selling a large position can move the market against you. Institutional investors face this constraint; retail investors are less affected for typical portfolio sizes

Small-Cap ETFs and Index Funds

The simplest and most cost-effective way for most investors to access Australian small companies is through index ETFs - capturing the small-cap premium without requiring individual stock research.

  • VSO (Vanguard MSCI Australian Small Companies Index ETF): Tracks the MSCI Australia Small Cap Index - approximately 200 smaller Australian companies outside the ASX 300. MER 0.30%. Provides broad small-cap exposure without concentration risk
  • ISO (iShares S&P/ASX Small Ordinaries ETF): Tracks the S&P/ASX Small Ordinaries Index - ASX 300 to ASX 400 companies. MER 0.55%. More concentrated than VSO in the 100 smallest S&P/ASX 400 companies
  • MVS (VanEck Small Companies Masters ETF): Actively managed small-cap ETF - targets quality small-cap companies using quantitative screening. MER 1.00%. Higher cost than passive options but seeks to avoid the 'junk' end of small-cap indices
  • SMLL (BetaShares Australian Small Companies Select ETF): Screens small-cap universe for quality factors - profitability, stability, low leverage. MER 0.39%. Tilts toward higher-quality small companies
  • Small-cap index funds include many poor businesses: A criticism of passive small-cap ETFs is that they include all small companies - including many that are loss-making, cash-burning, or fundamentally impaired. Some investors prefer actively managed small-cap funds or factor-screened ETFs to avoid this exposure
  • Global small-cap exposure: VISM (Vanguard MSCI International Small Companies Index ETF, MER 0.32%) provides international small-cap exposure - accessing the global small-cap premium beyond the ASX. Complements Australian small-cap allocation

Listed Investment Companies (LICs) in Small Caps

Australian small-cap LICs have a long track record and provide active management by specialist teams. Understanding LIC mechanics - including the premium/discount to NAV - is essential before investing.

  • How LICs differ from ETFs: LICs are closed-end - they issue a fixed number of shares that trade on the ASX. The share price can trade at a premium or discount to the underlying net asset value (NAV). ETFs trade at or near NAV through the creation/redemption mechanism; LICs do not have this mechanism
  • Discount/premium dynamics: A LIC trading at a 10% discount to NAV means you are buying $1.10 of underlying assets for $1.00 - potentially attractive. A LIC at a premium means you are paying above asset value - typically only justified if the manager has demonstrated consistent after-fee outperformance
  • Established small-cap LICs: WAM Capital (WAM), Mirrabooka Investments (MIR), Acorn Capital Investment Fund (ACQ), Spheria Emerging Companies (SEC) - each with distinct investment philosophies and track records. Review 5–10 year after-fee performance relative to the S&P/ASX Small Ordinaries benchmark
  • Dividend smoothing: LICs can retain profits to smooth distributions in weak years - maintaining dividend payments through market downturns when underlying company dividends may fall. This makes some LICs attractive for income-focused investors
  • Fee drag: Active LIC management fees (0.5–1.5% p.a. plus performance fees) must be overcome by outperformance. Many LICs have delivered after-fee returns competitive with the index; some have not - research performance carefully before investing
  • Tax efficiency: LICs pay tax internally at the corporate rate before distributing - dividends carry franking credits. This differs from ETFs where tax is in the investor's hands. For investors in low tax brackets, this may be less efficient; for high-rate taxpayers, franking credits provide value

Direct Small-Cap Stock Selection: What to Look For

Investors who select individual small-cap stocks require a more rigorous analytical process than large-cap investing - the consequences of getting it wrong are more severe and the information available is often thinner.

  • Quality of management is paramount: For small companies, the CEO and board determine outcomes more than in large companies where institutional processes are more established. Research founder-led companies, insider ownership levels, track record across previous companies, and compensation alignment
  • Balance sheet strength: Small companies with net cash positions and no debt can survive adversity; those with heavy debt and negative operating cash flow cannot. Prioritise companies with at least 12 months of operating runway from cash on hand
  • Revenue growth and path to profitability: For pre-profit small companies, revenue growth rate, gross margin trajectory, and credible path to operating cash flow positivity are the key metrics. Avoid companies burning cash without clear near-term profitability milestones
  • Total addressable market (TAM) vs realistic market share: Small-cap promoters frequently cite enormous TAM figures to justify valuations. The relevant question is: what market share is realistically achievable in 5 years, and what is the company worth at that share?
  • Capital raises and dilution: Small companies frequently raise capital - issuing new shares that dilute existing shareholders. Frequent dilutive capital raises are a red flag; rare strategic raises at prices near or above the current price are more acceptable
  • Avoid speculative mining and biotech: Resource exploration and early-stage biotech companies can generate exceptional returns - but the base rate of failure is extremely high. These are lottery-ticket investments requiring deep specialist knowledge; most retail investors should access them through diversified funds rather than individual stocks

Portfolio Construction and Risk Management for Small Caps

Small-cap investing requires deliberate portfolio construction to prevent concentration risk from devastating overall returns. Here is how experienced small-cap investors manage the risk.

  • Limit total small-cap allocation: Most financial planning frameworks suggest small-cap shares represent 10–25% of the overall equity portfolio - enough to capture the size premium without over-exposing to small-company volatility
  • Diversify across at least 15–20 stocks if investing directly: A single small-cap stock losing 80% of its value (common for failed small-caps) destroys 4% of a 20-stock portfolio - uncomfortable but survivable. The same loss on a 5-stock concentrated portfolio is devastating
  • Use ETFs or LICs as the small-cap core: Even investors who enjoy direct stock picking should consider maintaining a passive small-cap ETF as the core holding and limiting direct stock picks to a small 'satellite' allocation
  • Longer investment horizon: Small-cap stocks can underperform for extended periods - sometimes 3–5 years of relative underperformance before the premium re-emerges. A short time horizon is incompatible with small-cap investing
  • Liquidity management: Hold small-cap positions in sizes that can be liquidated within a reasonable period (1–5 days at typical trading volumes) - avoid positions so large they cannot be exited without significantly moving the price
  • Patience with quality positions: The best small-cap outcomes come from identifying quality businesses early and holding through volatility as they grow into large-caps. The impulse to take profits early can be the biggest cost in small-cap investing
