In afternoon trade, the S&P/ASX 200 Index (ASX: XJO) is trading notably lower. At the time of writing, the benchmark index is down 0.9% to 7,458.5 points.
Four ASX shares that are falling more than most today are listed below. Here's why they are tumbling:
BHP Group Ltd (ASX: BHP)
The BHP share price is down 7% to $41.94. This decline is almost entirely attributable to the mining giant's shares trading ex-dividend this morning. Last month BHP released its full year results and declared a record fully franked final dividend of 200 US cents or 273.6 Australian cents per share. Eligible shareholders can now look forward to receiving this dividend later this month on 21 September.
NIB Holdings Limited (ASX: NHF)
The NIB share price is down 3.5% to $6.55. This also appears to have been driven by its shares going ex-dividend this morning. The private health insurer declared a fully franked final dividend of 14 cents per share last month. NIB will be paying this dividend to eligible shareholders on 5 October.
Northern Star Resources Ltd (ASX: NST)
The Northern Star share price has fallen almost 3% to $9.63. Investors have been selling the gold miner's shares amid broad weakness in the gold sector today. For example, the S&P/ASX All Ordinaries Gold index is down a disappointing 2% this afternoon.
Redbubble Ltd (ASX: RBL)
The Redbubble share price is down 2% to $4.10. This morning the ecommerce company revealed that its Co-Founder, former CEO, and current Chairman, Martin Hosking sold 5 million Redbubble shares on-market on Wednesday. Mr Hosking received a total consideration of $21 million for the shares. However, it is worth noting that even after this sale he remains the largest shareholder with 39.5 million shares. This is the equivalent of a 14.4% stake.
