Some of the biggest names on the ASX have come under heavy selling pressure following their recent earnings results. These are businesses many Australians know well, yet their share prices show even the strongest companies can face setbacks.
At the time of writing, the share price of James Hardie Industries (ASX: JHX) is down more than 27% in 2025, CSL Ltd (ASX: CSL) has fallen over 18%, and Commonwealth Bank of Australia (ASX: CBA) has slipped as much as 7.8% from its highs before recovering slightly.
James Hardie: Growth outlook questioned
James Hardie shares slumped after the company's latest update revealed lower-than-expected guidance for FY26. The building products company is navigating softer demand in key North American housing markets and rising costs that are squeezing margins. While the company remains a global leader in fibre cement products, investors were quick to punish the downgrade, with some analysts questioning whether the growth profile that once drove the stock's premium valuation has weakened.
CSL: Leadership in healthcare still under scrutiny
CSL, often seen as one of the ASX's most dependable healthcare names, also disappointed the market. While the company delivered revenue growth and progress across its core plasma and vaccines divisions, the demerger of Seqirus has raised questions about future earnings visibility. Add to that higher operating costs and ongoing foreign exchange headwinds, and the result was a sell-off of more than 18%. For long-term followers, the key remains CSL's ability to sustain investment in R&D and maintain its leadership in critical therapies.
CBA: Banking giant meets reality check
Australia's largest bank is another heavyweight to feel the heat. Commonwealth Bank reported a near flat profit result as higher funding costs and slower lending growth pressured margins. While the bank maintained its dividend, investors were rattled by management's cautious outlook in the face of a softening housing market and rising competition. At one stage, the stock was down almost 8%, showing how sensitive valuations are after years of strong performance.
Risk or opportunity?
Sharp price moves can be unnerving. Yet history shows that even blue-chip companies aren't immune to disappointment. The key lesson for investors is that markets often react strongly in the short term. Sometimes those reactions prove justified, while other times they can overshoot.
Rather than focusing solely on the share price swings, it can be useful to step back and reassess the underlying businesses. James Hardie, CSL, and Commonwealth Bank all remain leaders in their respective fields, with strong competitive positions. Whether today's prices represent opportunity or a sign of deeper challenges is something only time will tell — but volatility ensures the market never stays still for long.
