Key points
  • A lithium developer's shares fall 8% despite no new announcements; last week's significant rise possibly leads to profit-taking.
  • Advanced metal powder company's shares decline following an annual report showing a financial loss post-reverse acquisition.
  • A major miner's shares dip over 2% due to a pullback in iron ore prices ahead of a major holiday in China.

The S&P/ASX 200 Index (ASX: XJO) has followed Wall Street's lead and is pushing higher on Monday. At the time of writing, the benchmark index is up 0.7% to 8,848.4 points.

Ioneer Ltd (ASX: INR)

The Ioneer share price is down 8% to 16.5 cents. This is despite there being no news out of the US-based lithium developer. However, it is worth noting that the company's shares rocketed higher last week. So, today's decline could have been driven by profit-taking from some investors. Ioneer's shares remain up 18% since this time last week despite today's pullback. The catalyst for this gain appears to have been news that the US government was buying a stake in a fellow US-based lithium company. Investors may believe that Ioneer has potential to get an investment in the future as well.

Metal Powder Works Ltd (ASX: MPW)

The Metal Powder Works share price is down almost 5% to $4.06. This follows the release of the advanced metal powder production technology developer's annual report this morning. That report included consolidated financial statements following the reverse acquisition of Metal Powder Works Inc, which ultimately led to its listing earlier this year. It posted a loss of US$6.2 million.

Rio Tinto Ltd (ASX: RIO)

The Rio Tinto share price is down over 2% to $120.44. This may have been driven by a pullback in the iron ore price. According to Bloomberg, iron ore prices pulled back ahead of a major holiday in China that will see mainland markets close for a week from Wednesday.

Strike Energy Ltd (ASX: STX)

The Strike Energy share price is down 3% to 10.7 cents. This has been driven by the release of the energy company's full year results. Strike Energy posted a 59% increase in revenue to $72.7 million and an 87% jump in underlying EBITDA to $41.6 million. However, due to impairments, it recorded a massive net loss of $157.3 million for FY 2025. This relates to the downward revision in reserves at Walyering. Strike Energy's managing director and CEO, Peter Stokes, was pleased with the year. He said: "FY25 was a pivotal year for Strike. The completion of our Strategic Review has provided a clear roadmap to unlock value across our unique Perth Basin asset base. With production at Walyering delivering cashflows, construction underway at South Erregulla, West Erregulla progressing towards development and significant prospectivity providing a strong potential growth pipeline, Strike is firmly positioned to play a critical role in Western Australia's energy transition."
