The S&P/ASX 200 Index (ASX: XJO) is on course to record a small gain. At the time of writing, the benchmark index is up 0.2% to 8,165 points.
Four ASX shares that are rising more than most today are listed below. Here's why they are climbing:
Firefly Metals Ltd (ASX: FFM)
The Firefly Metals share price is up almost 9% to 87 cents. Investors have been buying this mineral exploration company's shares following the release of a drilling update for the Green Bay Copper-Gold Project in Canada. Firefly Metals revealed that its latest drilling has intersected high-grade copper and gold mineralisation more than 200m beyond the current mineral resource. Managing Director, Steve Parsons, said: "We are about to add a seventh rig because we have so many opportunities to pursue. There are very few projects which could justify such an aggressive drilling campaign but we have more than enough avenues of growth to warrant this."
Kelsian Group Ltd (ASX: KLS)
The Kelsian share price is up 14% to $3.18. This has been driven by the release of a trading update from the travel and transport company. Kelsian revealed that it is tracking towards lower end of its previous earnings guidance range of underlying EBITDA between $283 million and $295 million. There has been no change to FY 2025 capex estimates.
National Australia Bank Ltd (ASX: NAB)
The NAB share price is up 3% to $36.35. Investors have been buying the banking giant's shares following the release of its half year results. NAB reported cash earnings of $3.58 billion for the six months. This is up 0.8% on the second half of FY 2024 and 1% on the prior corresponding period. It was also ahead of the $3.49 billion that analysts at Macquarie Group Ltd (ASX: MQG) were expecting. NAB's CEO, Andrew Irvine, said: "We are managing our business well in continued challenging operating conditions. Cash earnings were 0.8% higher than 2H24, with underlying profit growth and lower credit impairment charges partially offset by a higher effective tax rate."
Zip Co Ltd (ASX: ZIP)
The Zip share price is up 11% to $1.79. The catalyst for this has been the release of a trading update from the buy now pay later provider this morning. Zip advised that momentum in total transaction value (TTV) growth has continued across both Australia and the United States. So much so, in the United States, year on year TTV growth for the month of April was above 40%. This is broadly in line with the 47.1% TTV growth it reported for the business during the third quarter of FY 2025. Management has also reaffirmed its FY 2025 guidance for cash EBTDA of at least $153 million.
