Commonwealth Bank of Australia (ASX: CBA)
The CBA share price is down 1.5% to $161.30. This may have been driven by a broker note out of Morgan Stanley this morning. According to the note, the broker has retained its underweight rating on CBA's shares with a reduced price target of $125.00. The broker has named Australia's largest bank as its least favoured major bank. Morgan Stanley's price target implies potential downside of 22% from current levels.
PLS Group Ltd (ASX: PLS)
The PLS share price is down over 3% to $5.93. Investors have been selling the lithium miner's shares despite there being no news out of it today. However, it is worth noting that most lithium stocks are falling on Friday. In addition, PLS recently reported some heavy insider selling, as we covered here.
Resolute Mining Ltd (ASX: RSG)
The Resolute Mining share price is down 6% to $1.12. Investors have been selling the gold miner's shares today after it released a disappointing update on its Syama operation. That update revealed that production during the second quarter of FY 2026 has been impacted by logistical and supply chain disruptions. As a result, Resolute Mining now expects Syama's second-quarter gold production to be around 30,000 ounces. This is well short of its original expectation of 40,000 ounces to 45,000 ounces. The company's CEO, Chris Eger, said: "Recent performance at Syama has been below expectations despite the significant changes implemented in Mali. These issues are well understood, and our focus is on stabilising operations and restoring consistent performance. Importantly, the broader business continues to perform well. The Company remains cash generative, supporting ongoing investment in growth, including the Doropo development, which continues to progress to plan."
Silver Mines Ltd (ASX: SVL)
The Silver Mines share price is down 3.5% to 13.5 cents. This morning, this silver developer announced that it has entered into an option underwriting agreement with Petra Capital to fully underwrite the exercise of unlisted options. It said: "The Company has decided to enter into the Underwriting Agreement for the purpose of providing certainty that it will raise additional funds of $7,556,782."
