Underperform in 2026: How Investors Should Respond

Ready to take control of your investment performance? Review your portfolio, check your benchmarks, and consider a strategy refresh for 2026.

Seeing your investment portfolio ‘underperform’ can be a tough pill to swallow, especially in a year as dynamic as 2026. But what does underperformance really mean, and how should Australian investors respond?

What Does ‘Underperform’ Mean in 2026?

In the world of finance, ‘underperform’ is more than just a disappointing quarterly report—it’s a technical term. An investment is said to underperform when its returns lag behind a specified benchmark or the market as a whole. For example, if the S&P/ASX 200 returns 8% in a year, but your managed fund delivers only 5%, your fund has underperformed its benchmark by 3%.

Underperformance can be measured over different time frames (monthly, yearly, or over several years) and across asset classes—shares, ETFs, superannuation, or managed funds. In 2026, with the ASX experiencing increased volatility and a growing preference for passive investing, understanding underperformance is more important than ever for everyday Australians.

How Should Australian Investors Respond to Underperformance?

It’s tempting to react emotionally to short-term underperformance, but wise investors take a measured approach. Here’s how to navigate it in 2026:

For example, in 2026, some actively managed Australian equity funds have underperformed the ASX 200 for the third year running, even as low-cost ETFs have tracked the index more closely. Investors are increasingly voting with their feet, shifting billions into passive products.
