Building a strong ASX share portfolio is one of the best ways to grow long-term wealth.

But what does a perfect portfolio look like?

While there's no one-size-fits-all approach, the key is to focus on diversification, quality, and a long-term mindset.

If you're looking to construct a rock-solid portfolio, here's how I would do it.

The foundation

The backbone of any great portfolio is high-quality ASX blue chip stocks—companies with strong earnings, reliable dividends, and a proven track record. These stocks help provide stability, especially during market downturns.

Some of the best ASX blue chips right now might include:

  • Macquarie Group Ltd (ASX: MQG) – A dominant player in investment banking with strong dividend payments.
  • CSL Ltd (ASX: CSL) – A global biotech leader with a history of innovation and strong earnings growth.
  • Goodman Group (ASX: GMG) – An integrated industrial property giant with a world class portfolio and sizeable development pipeline.
  • Wesfarmers Ltd (ASX: WES) – Owner of high-quality businesses like Bunnings, Kmart, and Officeworks.

These stocks act as anchors, helping to reduce volatility while still delivering steady returns.

Don't forget ASX growth stocks

While blue chips offer stability, ASX growth stocks can supercharge returns over the long run. The key is finding businesses with strong earnings potential, innovative products, and a competitive advantage.

Some exciting ASX growth stocks to consider:

  • Pro Medicus Ltd (ASX: PME) – A fast-growing health imaging technology company dominating its market.
  • Xero Ltd (ASX: XRO) – A cloud accounting platform provider with an estimated total addressable market of 100 million small to medium sized businesses.
  • WiseTech Global Ltd (ASX: WTC) – A global leader in logistics software, expanding rapidly worldwide.

These companies may experience volatility, but over time, they have the potential to significantly increase in value.

ASX ETFs for diversification

To reduce risk and gain exposure to a broad range of industries, adding exchange-traded funds (ETFs) to your portfolio could be a smart move.

ASX ETFs allow you to own a large basket of shares with a single investment.

Here are a couple of strong ASX ETFs to consider:

  • Betashares Nasdaq 100 ETF (ASX: NDQ) – Provides exposure to the 100 largest non-financial companies on the Nasdaq exchange. This includes many of the largest tech companies in the world.
  • iShares S&P 500 ETF (ASX: IVV) – It invests in the 500 largest companies in the United States.

Using ASX ETFs alongside individual stocks could create a balanced portfolio with both stability and growth potential.

Stick to a long-term strategy

No matter how well you build your portfolio, staying invested is the most important part of the process.

By holding great businesses for years, you can take advantage of compound growth, which is one of the most powerful forces in investing.

Foolish takeaway

The perfect ASX share portfolio is arguably one that balances stability, growth, diversification, and income. By combining blue chip stocks, high-growth opportunities, and ETFs, you can build a resilient and profitable portfolio that stands the test of time.

Most importantly, stay patient and stick to your strategy through thick and thin.
