As we move through April, I think investors are in an attractive position.
Markets have pulled back, potentially creating opportunities to pick up shares in quality companies at a discount to what people were willing to pay only recently.
Here are three popular ASX shares that I'd buy this month.

BHP Group Ltd (ASX: BHP)
When I look at BHP, I see a company that is closely tied to some of the biggest long-term trends in the global economy.
Copper demand is one of the clearest examples. Electrification, renewable energy, and infrastructure all require large amounts of copper, and I think that demand could remain strong for many years.
BHP also offers exposure to iron ore, which continues to underpin its earnings today, as well as longer-term projects like potash that could diversify future growth.
What makes BHP appealing to me right now is the balance. It is not just a growth story. It is also an income-generating business that can return capital to shareholders through the cycle.
In a market where uncertainty is rising again, I think that combination of income and long-term exposure to global demand is hard to ignore.
Commonwealth Bank of Australia (ASX: CBA)
Commonwealth Bank is often described as expensive. And I think that is fair.
But I also think there is a reason it continues to trade at a premium. CBA has consistently delivered strong returns, supported by its scale, brand strength, and leading position in the Australian banking system.
Even in a higher interest rate environment, it has shown an ability to maintain margins and generate reliable earnings.
For me, this is less about finding a bargain and more about owning quality. If I were building or adding to a long-term portfolio in April, I would still consider CBA shares because of its consistency and resilience.
It may not be the fastest grower, but it is one of the most dependable.
DroneShield Ltd (ASX: DRO)
DroneShield sits at the opposite end of the spectrum. This is not a mature, steady business. It is a company operating in a rapidly evolving industry with significant potential.
What stands out to me is how quickly the business has scaled. In FY25, the company delivered around $260 million in revenue, roughly four times higher than the previous year, while also achieving profitability.
At the same time, its sales pipeline has grown to around $2.3 billion across nearly 300 deals, which suggests a large opportunity set ahead.
I also find the broader industry backdrop compelling. Counter-drone technology is still in its early stages, with adoption across both military and civilian markets expected to expand over time. The company itself points to a very large addressable market and increasing global demand for these solutions.
Of course, this kind of growth story comes with more risk.
But I think that is part of the appeal. In a diversified portfolio, DroneShield shares could provide exposure to a theme that is very different from traditional sectors.
Foolish takeaway
I think combining these types of ASX shares in a portfolio can make a lot of sense for long-term investors.
BHP offers exposure to global growth and commodities, CBA provides stability and income, and DroneShield brings higher-risk, higher-potential growth tied to a rapidly evolving industry.
