Building a portfolio from scratch can feel like a big task.
But it does not have to be complicated. In fact, a well-constructed portfolio of just 10 ASX shares can provide diversification, income, and long-term growth potential.
The key is balance. You want exposure to different sectors, business models, and growth drivers so you are not relying on just one theme to succeed.
Here is one way investors could build a winning 10-ASX share portfolio in 2026.

Start with high-quality core holdings
The first ASX share that could anchor a portfolio is CSL Ltd (ASX: CSL).
CSL is a global healthcare leader with defensive earnings and long-term growth drivers. Demand for its therapies is supported by ageing populations and rising healthcare needs, making it a strong foundation.
Another ASX share that could play a similar role is Wesfarmers Ltd (ASX: WES).
Wesfarmers offers diversification through retail, chemicals, and industrial operations. Its ability to allocate capital effectively has been a key driver of long-term returns.
A third ASX share to consider is Commonwealth Bank of Australia (ASX: CBA).
While not the cheapest bank, CBA provides reliable earnings and fully franked dividends, making it a cornerstone for many Australian portfolios.
Add growth engines to drive returns
A fourth ASX share that could boost long-term returns is Xero Ltd (ASX: XRO).
Xero continues to expand globally, with its cloud accounting platform gaining traction in multiple markets. It represents a scalable growth opportunity.
Another ASX share that could fit here is WiseTech Global Ltd (ASX: WTC).
WiseTech's CargoWise platform is deeply embedded in global logistics, giving it strong competitive advantages and a long runway for growth.
A sixth ASX share to consider is Pro Medicus Ltd (ASX: PME).
Pro Medicus is a high-margin healthcare technology company that continues to win major contracts globally. Its growth profile remains very strong.
Include income and stability
A seventh ASX share that could add income is Telstra Group Ltd (ASX: TLS).
Telstra offers attractive dividend yields and is now focused on growth through its Connected Future 30 strategy, combining income with improving fundamentals.
Another ASX share in this category is Transurban Group (ASX: TCL).
Transurban provides steady, inflation-linked cash flows from its toll road assets, making it a reliable income generator.
Add structural and thematic exposure
A ninth ASX share that could round out the portfolio is Goodman Group (ASX: GMG).
Goodman provides exposure to logistics and data infrastructure, both of which are benefiting from e-commerce and digitalisation trends.
Finally, a tenth ASX share to consider is Life360 Inc (ASX: 360).
Life360 offers exposure to a growing global user platform that is increasingly monetising its base. It adds a higher-risk, higher-reward element to the portfolio.
The bottom line
A 10-share portfolio like this gives investors exposure to defensive healthcare, financials, technology, infrastructure, and emerging growth opportunities.
By combining quality, growth, and income, investors can build a portfolio that is well positioned to navigate different market conditions and deliver strong long-term returns.
