In afternoon trade, the S&P/ASX 200 Index (ASX: XJO) is on course to end the week with a small decline. At the time of writing, the benchmark index is down 0.2% to 8,735.1 points.

Four ASX shares that are falling more than most today are listed below. Here’s why they are ending the week in the red:

4DMedical Ltd (ASX: 4DX)

The 4DMedical share price is down almost 11% to $4.08. This is despite the respiratory imaging technology company announcing that its non-contrast ventilation-perfusion imaging solution, CT:VQ, has been approved by the Therapeutic Goods Administration (TGA). The TGA has also included the product in the Australian Register of Therapeutic Goods (ARTG), which enables commercial deployment across Australia. Broad weakness in the tech sector on Friday could be overshadowing this news.

Centuria Capital Group (ASX: CNI)

The Centuria Capital share price is down 2.5% to $1.98. This has been driven by the property company’s shares going ex-dividend this morning for its latest payout. Eligible shareholders can now look forward to receiving Centuria Capital’s 5.2 cents per share final dividend in a couple of months. The company is expecting to make the payment on 27 August.

Judo Capital Holdings Ltd (ASX: JDO)

The Judo Capital share price is down a further 1.5% to 90 cents. This small business lender’s shares have been sold off this week after it increased its cost of risk and downgraded its earnings guidance. Judo Capital revealed that it now expects its FY 2026 cost of risk to be in the range of $116 million to $122 million. This has been caused by three exposures across different sectors that have recently emerged. As for its earnings, Judo Capital now expects its profit before tax in FY 2026 to be between $163 million and $169 million. This is down from its previous guidance of between $180 million and $190 million. The company’s CEO, Chris Bayliss, said: “While today’s update is partly a result of the macro environment, it is nevertheless disappointing.”

Worley Ltd (ASX: WOR)

The Worley share price is down 4% to $10.64. This may have been driven by the release of a broker note out of Ord Minnett. According to the note, the broker has downgraded the professional services company’s shares to a hold rating (from accumulate) with a trimmed price target of $12.70 (from $13.10). This was driven by a profit guidance downgrade this week due to the negative impacts of the Middle East conflict.

With just a few hours of trade left before Friday’s closing bell, the S&P/ASX 200 Index (ASX: XJO) is down 0.7% for the week, with DroneShield Ltd (ASX: DRO), WiseTech Global Ltd (ASX: WTC) and Judo Capital Holdings Ltd (ASX: JDO) shares all falling far harder.

Here’s why investors have been bidding down the ASX 200 heavyweights this week.

Judo shares plunge on profit downgrade

Judo shares are down 2.2% in intraday trade today, changing hands for 90 cents apiece. That sees shares in the ASX 200 challenger bank down a sharp 39.9% since last Friday’s close.

All of those losses can be pinned to Thursday’s decidedly underwhelming market update.

Judo shares closed down a precipitous 40.4% yesterday after the bank increased it forecast full year FY 2026 cost of risk to between $116 million and $122 million.

And investors were overheating their sell buttons after Judo downgraded is FY 2026 profit before tax guidance to be between $163 million and $169 million. While that still represents year on year profit growth of around 30%, the revised guidance was down from prior FY 2026 profit expectations of between $180 million and $190 million.

Commenting on the downgrade, Judo Bank CEO Chris Bayliss said:

We continue to see strong underlying momentum in the business. Recent credit outcomes have been driven by a small number of customers, who we are actively working with.

DroneShield shares losing altitude

DroneShield shares also had a week to forget, though not nearly so bad a Judo shares.

Shares in the ASX 200 drone defence company are down 4.8% at time of writing, trading for $2.30 each. That sees the DroneShield share price down 16.4% since last Friday’s close.

There was no market sensitive news out this week to explain the sharp decline. Though the company did announce the appointment of retired Rear Admiral Lee Goddard as an independent non-executive director.

But investors may have been favouring their sell buttons amid expectations that the peace deal in the Middle East could impact future demand for drone defence systems.

Which brings us to…

WiseTech shares sink on new White allegations

Joining DroneShield and Judo shares on the decline this week is WiseTech.

Shares in the ASX 200 logistics software solutions company are down 1.7% at time of writing, trading for $30.85 apiece. That sees the WiseTech share price down 16.4% for the week.

WiseTech shares plunged 18.4% on Monday following concerning new media reports involving founder and executive chairman Richard White.

Investors were heading for exit following news that the Australian Federal Police are investigating White over allegedly exploiting a female employee’s immigration status and financial position and providing false information on a visa application.

Westpac Banking Corp (ASX: WBC) is paying shareholders a fully franked interim dividend of 77 cents per share today.

For many investors, this is exactly why bank shares are so popular. The major banks regularly return billions of dollars to shareholders through dividends, and these payments can form an important part of a passive income strategy.

Some Westpac shareholders will have elected to use the dividend reinvestment plan, allowing their dividend to buy more shares in the bank.

Others will receive the dividend as cash. That money could be spent, saved, or reinvested elsewhere on the ASX.

For investors wanting to use their Westpac dividends to diversify into other high-quality blue chips, the three shares below could be worth considering.

Goodman Group (ASX: GMG)

The first ASX blue chip to consider is Goodman.

Goodman gives investors exposure to logistics, industrial property, and data centres across key global markets.

These assets sit behind some of the biggest changes in the economy. Ecommerce needs warehouses close to customers, global supply chains need efficient distribution networks, and cloud computing and artificial intelligence are increasing demand for data centre infrastructure.

That gives Goodman a powerful long-term growth profile.

The company has also built a strong reputation as a developer and manager of complex property assets. This means it is not simply collecting rent from warehouses. It is helping major customers solve infrastructure problems in markets where well-located land can be scarce.

ResMed Inc (ASX: RMD)

Another option for Westpac dividend cash is ResMed.

ResMed is a medical device company focused on sleep apnoea treatment and connected respiratory care.

This gives it exposure to a large medical need. Many people with sleep apnoea remain undiagnosed, while greater awareness of sleep health could support demand for treatment over the long term.

The company’s business model also has an attractive recurring element. Patients using its devices often need masks, accessories, software support, and ongoing care. That can create repeat revenue over time and help smooth the business beyond one-off device sales.

Healthcare shares can still be volatile, but ResMed’s global market position and long-term demand drivers make it a high-quality blue chip to consider.

Wesfarmers Ltd (ASX: WES)

A third ASX blue chip to look at is Wesfarmers. It owns a collection of strong retail and industrial businesses, including Bunnings, Kmart, Officeworks, and its chemicals, energy and fertilisers operations.

This gives investors exposure to a diversified group with multiple ways to grow.

Bunnings remains one of the strongest retail franchises in Australia, while Kmart has built a powerful position in value-focused retail. These businesses benefit from scale, trusted brands, and a long history of disciplined execution.

Wesfarmers has also shown a willingness to invest in new opportunities and reshape its portfolio over time. That capital allocation track record is one reason investors often view it as one of the ASX’s highest-quality companies.
