Investing $50,000 in the share market is a meaningful step. It is large enough to build a proper portfolio, but still small enough that every decision matters.
If I had that amount to invest in ASX shares today, I would focus on building a balanced portfolio rather than trying to find a single winner. The goal would be to combine growth, income, and diversification so the portfolio can perform across different market conditions.
Here is how I would approach it.

Start with a strong foundation
The first thing I would do is anchor the portfolio with broad market exposure.
An exchange-traded fund (ETF) like the Vanguard Australian Shares Index ETF (ASX: VAS) would likely take a meaningful allocation. It provides exposure to hundreds of Australian shares across multiple sectors, including banks, resources, healthcare, and consumer businesses.
This helps reduce the risk of relying too heavily on a handful of individual shares. It also ensures the portfolio participates in the overall growth of the Australian market.
Add high-quality blue chips
Next, I would include a few established blue-chip companies with long operating histories and durable earnings.
For example, Wesfarmers Ltd (ASX: WES) offers exposure to some of Australia's most recognisable retail businesses, including Bunnings and Kmart. Its disciplined management and diversified operations have supported steady long-term growth.
Similarly, Commonwealth Bank of Australia (ASX: CBA) could add stability and dividend income. While bank shares can fluctuate with economic conditions, CBA has consistently delivered strong profitability and fully franked dividends.
These kinds of companies help provide balance and reliability within the portfolio.
Include a few growth names
With the core of the portfolio established, I would allocate a portion to higher-growth businesses.
One example could be Pro Medicus Ltd (ASX: PME). The company's medical imaging software platform has been gaining traction globally and operates with a highly scalable, capital-light business model.
Growth stocks tend to be more volatile, but they can also deliver strong long-term returns if the underlying business continues to expand.
Holding a small number of high-quality growth names can help boost overall portfolio performance over time.
Think about income as well
Even if income is not the primary goal today, including a reliable dividend payer can still be beneficial.
Companies like Telstra Group Ltd (ASX: TLS) generate steady cash flows from essential services such as mobile connectivity and broadband. That stability can provide a regular stream of dividends and help smooth returns during more volatile periods.
Why diversification matters
With $50,000, diversification becomes possible without spreading the portfolio too thin.
A mix of ETFs, blue chips, growth companies, and dividend payers helps balance risk. If one sector struggles, the others may still perform well.
The aim is not to predict exactly which stock will outperform. It is to build a portfolio that can grow steadily over many years.
Foolish takeaway
If I had $50,000 to invest in ASX shares, I would build a diversified portfolio combining broad market exposure, high-quality blue chips, and a few carefully selected growth companies.
That balanced approach may not always produce the biggest short-term gains, but it gives investors a solid foundation for long-term wealth creation.
