ASX Midday Market Wrap: BHP Gains, CSL Extends Losses

On July 31, 2026, the Australian share market traded higher in midday trading as gains in mining stocks balanced weakness in the healthcare sector. The ASX 200 moved into positive territory, with BHP providing much of the support while CSL extended its recent decline. Investors were also assessing corporate earnings, commodity prices, and overseas market performance for clues on where the market could head before the closing bell.

ASX 200 Midday Performance: Markets Stay Positive Despite Mixed Sector Moves

Latest Market Snapshot

The Australian share market posted modest gains during the midday session on July 31, 2026. By early afternoon, the S&P/ASX 200 had climbed about 0.2% to around 8,985 points, helped by stronger global market sentiment. Even so, losses among several heavyweight stocks kept the index from moving much higher.

Mining companies led the advance, with BHP attracting solid buying interest. Healthcare was the weakest-performing sector as CSL remained under pressure. Financial stocks traded without a clear direction, while technology shares slipped after broker downgrades weighed on some of the sector’s largest names.

Markets also took encouragement from Wall Street, where stronger-than-expected corporate earnings lifted investor confidence overnight. Most major Asian markets traded higher as well, giving Australian equities additional support. Even so, stock-specific news and earnings updates continued to shape trading across the market.

Why BHP Shares are Rising While CSL Continues to Slide?

Why Is BHP Supporting the ASX 200?

BHP was one of the biggest contributors to the market’s gains as investors returned to mining stocks. Confidence in long-term demand for iron ore and copper encouraged buying, while steady commodity prices added to positive sentiment across the materials sector. That strength helped offset losses in other parts of the market.

According to Meyka, BHP continues to have a positive outlook, supported by demand for industrial metals linked to infrastructure spending and the global energy transition.

BHP Stock Snapshot

• Short forecast: Positive while commodity demand remains firm.
• Technical analysis summary: The stock is holding above major support levels, with momentum improving despite the possibility of short-term volatility.
• What Meyka says: The AI stock analysis tool points to positive sentiment, backed by BHP’s strong exposure to copper and iron ore.

Morgan Stanley has also maintained a positive view on BHP. The firm expects demand for metals used in artificial intelligence infrastructure, electric vehicles, and renewable energy projects to continue supporting the company’s long-term earnings.

Why are CSL Shares Still Falling?

CSL remained under pressure during Friday’s session after analysts lowered their expectations for the healthcare company. Recent broker commentary continued to weigh on sentiment, making CSL one of the largest drags on the ASX 200 even as the broader market traded higher.

Healthcare stocks have generally underperformed in recent weeks as investors shifted toward sectors tied more closely to economic growth, including mining and resources. Although CSL’s long-term business fundamentals remain solid, many investors appear to be waiting for the company’s next earnings update and any changes to its outlook before increasing their positions.

Biggest Decliners

Several large-cap companies weighed on the market despite the overall gains.

The main decliners included:

• CSL, following weaker analyst expectations.
• WiseTech Global, after Macquarie raised concerns about its valuation.
• Fortescue, which fell after announcing a sizeable writedown related to the Iron Bridge project.

The mixed performance across sectors suggests investors are staying selective as Australia’s earnings season gathers pace.

What Investors are Watching This Afternoon?

Attention is now turning to whether the ASX can hold its gains through the remainder of the trading session. Commodity prices, particularly iron ore and copper, are likely to remain a major influence on mining stocks.

Investors are also keeping an eye on:

• Upcoming Australian corporate earnings announcements.
• Global economic data and expectations for future interest rates.
• Overnight movements in US markets ahead of next week’s trading.

Any fresh company announcements, earnings surprises, or broker rating changes could quickly shift sentiment before the market closes.

Conclusion

The ASX stayed in positive territory at midday as strength in BHP and other mining stocks outweighed continued weakness in the healthcare sector. CSL remained one of the biggest drags on the benchmark index, while investors continued to react to earnings reports, commodity prices, and global market signals. The remainder of the session is likely to depend on company-specific developments and whether buying in the resources sector continues through the close.
