With 2025 drawing to a close, the Australian share market finds itself at an interesting crossroads.
The market is sitting close to a record high with investor sentiment remaining strong, but at the same time there are geopolitical risks building.
For investors, that combination brings both opportunity and risk. The big question is how to position a portfolio for what's coming next.
Should you lean into growth? Stay defensive? Or take a more balanced approach that can weather both optimism and volatility?
The answer depends on time horizon and temperament. But with 2026 shaping up as a potentially pivotal year for markets, there are three key steps investors can take right now to strengthen their portfolios.

Focus on quality
When markets are strong, it is easy to spread investments too thinly across what is working. But history shows that sustainable returns come from owning a few great companies, not dozens of average ones.
This is a good time to double down on quality. This means businesses with strong balance sheets, reliable cash flows, and competitive advantages that protect profits through the cycle.
Think of ASX names like ResMed Inc. (ASX: RMD), Goodman Group (ASX: GMG), or Wesfarmers Ltd (ASX: WES). These are companies that continue to deliver through both booms and slowdowns. They might not shoot the lights out every quarter, but they tend to keep compounding value for patient investors.
Quality isn't exciting day to day, but it is what keeps portfolios intact when sentiment shifts.
Blend growth and income
With further interest rate cuts likely, cash returns may fall again in 2026. That means investors relying heavily on term deposits or savings accounts could see their income shrink.
The solution isn't abandoning safety, it is about rebalancing.
Income investors might consider adding exposure to dividend ETFs such as the Vanguard Australian Shares High Yield ETF (ASX: VHY).
Meanwhile, those still in the accumulation phase can look at growth-focused ASX ETFs like the Betashares Global Quality Leaders ETF (ASX: QLTY) or the iShares S&P 500 ETF (ASX: IVV) to keep compounding wealth over the long term.
Having both growth and income streams working together provides flexibility, and reduces the temptation to time the market.
Keep some cash
Even in strong markets, it is smart to keep some dry powder. Cash gives you flexibility to buy when volatility returns. And it always does eventually.
But holding too much can quietly cost you returns. With inflation still sitting around 3%, uninvested cash is losing value in real terms every year.
A balanced approach is to hold enough liquidity for emergencies or short-term opportunities, but make sure the rest is allocated to assets that can actually grow. Regular contributions, even small ones, can have an outsized impact thanks to compounding.
A year to stay proactive
If 2025 was about hitting the accelerator and riding the AI boom, 2026 may be about shifting gears. Lower rates, slower growth, and shifting market leadership could mean a very different investing landscape from the past few years.
The investors who do best won't be the ones making big bets, they will be the ones positioned early, owning quality, staying diversified, and thinking long term.
So, before the calendar turns, it could pay to take a moment to look and see if your portfolio is ready for 2026.
