ASX small-caps could be where the next wave of returns comes from

If you’re trying to beat the S&P/ASX 200 Index (ASX: XJO), it helps to be honest about the playing field.

Australia’s largest companies like Commonwealth Bank of Australia (ASX: CBA) and BHP (ASX: BHP) are heavily researched, widely owned, and constantly scrutinised by analysts and institutions. By the time an opportunity becomes obvious in the top 200, it is often already reflected in the share price.

That doesn’t mean outperformance is impossible. It just means investors looking for stronger returns may need to broaden their search. For many, that search leads to ASX small-caps.

Why small caps can offer more opportunity

The ASX small-cap universe is far larger and more diverse than the headline indices suggest. It includes emerging leaders, niche operators, turnaround stories, and businesses still flying under the radar.

This part of the market is also less efficiently priced. Many small companies are followed by few analysts, and institutional ownership is often limited. As a result, share prices can lag behind fundamentals — creating potential opportunities for patient investors.

Small-caps also tend to respond more dramatically to changes in earnings expectations, sentiment, or economic conditions. While that volatility can be unsettling, it is also what creates the possibility of outsized gains.

Rotation can leave quality businesses behind

Markets move in cycles. Capital rotates between sectors, styles, and company sizes as conditions evolve.

When investors crowd into popular themes, other areas of the market can be left behind. ASX small-caps often feel this effect more acutely, with entire segments sold down regardless of individual company performance.

At times, this can result in high-quality businesses trading at prices that reflect pessimism rather than reality. For investors willing to look past short-term noise, rotation can open the door to opportunities that are harder to find in larger, more stable stocks.

Depressed valuations can support future returns

After several years of lagging large caps, parts of the small-cap market have been trading on noticeably lower valuations.

That does not guarantee a rebound. Markets can stay out of favour longer than expected. Still, when expectations are already low, companies often need less “good news” to surprise on the upside.

If earnings stabilise or improve, valuations can recover alongside profits. Over time, that combination has the potential to support stronger returns than those available in more fully priced parts of the market.

Small companies can change faster

Large companies can grow, but their size often limits how quickly they can transform.

Small-caps, by contrast, can materially change their trajectory in a short period. That might involve reaching profitability, expanding into new markets, securing a major contract, or strengthening the balance sheet.

These inflection points tend to have a greater impact on smaller businesses, which is why returns across the small cap universe are far more dispersed. Some companies struggle. Others go on to deliver substantial gains as their prospects improve.

M&A activity can act as a tailwind

Another factor supporting interest in ASX small caps is mergers and acquisitions.

When organic growth is hard to find, larger companies often look to acquisitions to expand earnings. Smaller, well-run businesses can become attractive targets — particularly when valuations are reasonable and growth elsewhere is scarce. Just look at some of 2025’s small cap takeover winners like RPM Global (ASX: RUL).

Foolish takeaway

ASX small-caps are not without risk.

They can be more volatile, less liquid, and more sensitive to economic shocks than large caps. That is the price investors pay for the potential upside.

For many, the question isn’t whether small-caps are better than large-caps. It’s whether small-caps can play a role in a diversified portfolio — particularly for investors seeking opportunities beyond the most crowded parts of the market.

For investors willing to think long term and accept volatility, ASX small-caps could be where the next wave of returns comes from.
