Shares in James Hardie Industries PLC (ASX: JHX) looked unstoppable to start April.
The ASX heavyweight surged 11% in the first two weeks of the month, riding a wave of optimism. But that rally hit a wall on Thursday, when the stock dropped 4.2% to $28, making it one of the day's biggest laggards.
So, is this just a minor hiccup for James Hardie shares, or a sign that the momentum has already fizzled out?

Risks investors shouldn't ignore
The reality is that James Hardie is not without its challenges.
The biggest concern remains its heavy exposure to the US housing market. If housing starts slow — or simply stays weak — demand for building materials could soften. That's been a key factor weighing on the share price recently, and it's not going away anytime soon.
There are also execution risks tied to its acquisition of AZEK. Integrating a large business is never simple. Management needs to merge operations smoothly, extract promised synergies, and keep costs under control. Any stumble here could quickly show up in earnings.
And then there's the broader backdrop. Investor sentiment toward cyclical and industrial stocks has been shaky. Even strong companies can get dragged lower when the market mood turns cautious, adding another layer of volatility for shareholders.
Strong foundations still in place
Despite those risks, it would be a mistake to write off James Hardie shares too quickly.
The roughly $15 billion company remains the global leader in fibre cement siding and trim, with a dominant position in the US — its most important market. That scale delivers real advantages, including pricing power and a competitive moat that few rivals can match.
Operationally, the business is still performing well. In its latest quarterly update, net sales jumped 30% to $1.24 billion for the three months to 31 December 2025. Adjusted EBITDA rose 26% to $329.9 million. Those are not the numbers of a company in trouble.
There's also a compelling long-term growth story unfolding.
The AZEK acquisition has significantly expanded James Hardie's addressable market. It's no longer just a siding business. It's building a broader outdoor living platform across decking, railing, and exterior solutions. If management executes well, this could unlock a new phase of growth.
What do experts think?
Most brokers are upbeat on James Hardie shares and rate them a buy. They have set an average 12-month price target of $39.53, which points to a potential gain of 41% at current levels.
According to broker Morgans, the outlook remains attractive. The firm has a buy rating on James Hardie with a price target of $45.75. Based on the current share price of $28, that implies potential upside of roughly 63%. That's a sizeable vote of confidence.
Foolish Takeaway
Short-term momentum may have stalled, and risks are clearly in play. But the underlying business still looks robust, with strong market positioning and meaningful growth drivers.
For investors, the key question isn't whether the share price dipped this week, it's whether the long-term story remains intact. Right now, the answer appears to be yes.
