The S&P/ASX 200 Index (ASX: XJO) is having a strong session. In afternoon trade, the benchmark index is up 0.9% to 7,009 points.
Four ASX shares that are rising more than most today are listed below. Here's why they are climbing:
ALS Ltd (ASX: ALQ)
The ALS share price is up 8.5% to $11.59. This follows the release of the testing solutions company's half-year results. ALS reported an underlying net profit after tax of $158 million, which was a touch above the top end of its guidance range.
Catapult Group International Ltd (ASX: CAT)
The Catapult share price is up 10% to $1.02. This morning, this sports technology solutions company released its half-year results and reported a 21% increase in constant currency revenue to US$49.8 million and a 21% lift in constant currency annualised contract value to US$79.7 million. This helped underpin positive free cash flow of US$1.4 million for the half.
Rio Tinto Ltd (ASX: RIO)
The Rio Tinto share price is up 2% to $122.42. Investors have been buying this mining giant's shares after a positive night for commodity prices. This was particularly the case for copper, which jumped after short sellers closed positions. The S&P/ASX 200 Resources index is up 1.9% in afternoon trade.
Woodside Energy Group Ltd (ASX: WDS)
The Woodside share price is up 3% to $32.77. This appears to have been driven by a solid rise in oil prices overnight. According to CNBC, this was caused by the release of OPEC's monthly report, which blamed speculators for a recent drop in prices. The oil cartel also boosted its 2023 forecast for growth in global oil demand and stuck to its relatively high 2024 prediction.
