6 min read | July 20, 2026 09:33 AM AEST | By Sam

Highlights

  • Woodside Energy (ASX:WDS) and Wesfarmers (ASX:WES) remain among the shares displaying stronger upward price structures.
  • 4DMedical (ASX:4DX), DroneShield (ASX:DRO) and Electro Optic Systems (ASX:EOS) are showing weaker technical patterns after sharp market reversals.
  • Paladin Energy (ASX:PDN) and Hot Chili (ASX:HCH) highlight continued pressure across uranium and critical-minerals shares.

Australian equities are presenting a sharply divided technical picture, with energy, diversified industrial and selected financial shares displaying firmer chart structures while healthcare, defence technology and mining names face considerable downward momentum. The latest market scans place Woodside Energy (ASX:WDS) and Wesfarmers (ASX:WES) among the more resilient upward trends, while 4DMedical (ASX:4DX), DroneShield (ASX:DRO), Electro Optic Systems (ASX:EOS), Hot Chili (ASX:HCH) and Paladin Energy (ASX:PDN) remain under technical pressure. The divergence shows that performance across the ASX 200 is increasingly being driven by sector rotation and company-specific momentum rather than a uniform market trend.

What do the latest ASX chart scans show?

Technical scans commonly assess factors such as price direction, momentum, support and resistance levels, moving averages and the balance between market demand and supply.

An upward trend generally develops when a share records a sequence of rising peaks and higher troughs. A downward trend tends to feature falling peaks, weaker rebounds and repeated tests of lower support levels.

These chart structures do not determine what will happen next. They instead provide a visual representation of how market sentiment and price behaviour have developed over a particular period.

The current scans suggest that energy and selected defensive businesses retain relatively constructive momentum, while numerous mining, healthcare and defence-related companies are experiencing weaker price structures.

Woodside Energy retains upward momentum

Woodside Energy remains one of the more prominent names on the upward-trend list following renewed strength across the Australian energy sector.

Oil and gas companies have benefited from heightened attention on global supply conditions, Middle East tensions and changing expectations for energy prices. These factors have helped energy shares outperform several other areas of the Australian market.

From a technical perspective, Woodside's recent advance suggests that demand has remained comparatively firm. The companys shares have strengthened over both shorter and longer observation periods, supporting its placement among the more established positive trends.

Future direction may remain sensitive to crude oil prices, production developments and broader geopolitical conditions.

Wesfarmers shows defensive strength

Wesfarmers also appears among the stronger chart patterns as investors continue to favour established businesses with diversified operations.

The group has exposure to hardware, chemicals, industrial products and consumer retail through businesses including Bunnings and Kmart. Its broad operating structure can provide some resilience when market sentiment becomes uneven.

Wesfarmers' recent price performance indicates that market demand has remained relatively consistent despite weakness across technology and materials companies.

Investors examining the chart may focus on whether the shares can maintain their sequence of stronger levels or whether momentum begins to flatten around previous resistance areas.

AMP and Computershare join the stronger trends

AMP (ASX:AMP) has also featured prominently after recording a sharp positive response to its latest earnings update.

The financial services company has attracted attention following improved operating commentary and stronger expectations surrounding its business performance.

Computershare (ASX:CPU), a global provider of registry and corporate administration services, also appears within the upward-trend scan. Its price structure reflects relatively steady market demand compared with companies experiencing abrupt reversals.

Other names displaying constructive technical behaviour include oOh!media (ASX:OML) and Washington H. Soul Pattinson (ASX:SOL).

Why is 4DMedical under technical pressure?

4DMedical has moved onto the downward-trend list following a steep decline from previously elevated levels.

The respiratory imaging technology company experienced substantial earlier momentum, meaning the recent reversal is occurring after an extended period of strong market interest.

When a share has advanced rapidly, even a relatively brief change in sentiment can lead to sharp price adjustments as investors reassess valuation, commercial milestones and operational developments.

The current chart pattern suggests that upward momentum has weakened considerably. Market participants may monitor whether the shares establish a stable support area or continue recording lower price levels.

DroneShield and EOS lose momentum

Defence technology companies DroneShield and Electro Optic Systems are also showing weaker chart structures.

DroneShield develops counter-drone detection and electronic protection systems, while Electro Optic Systems operates across defence and space technology. Both companies previously attracted considerable interest as governments increased spending on security and defence systems.

However, strong earlier advances can leave shares vulnerable to rapid corrections when market expectations become difficult to maintain.

The latest scans indicate excess supply across both names, with repeated downward movements suggesting that sentiment has shifted from earlier enthusiasm towards greater caution.

Future technical improvement would generally require a period of stabilisation followed by evidence of stronger demand and higher price structures.

Hot Chili reflects pressure across copper developers

Hot Chili remains among the notable downward trends as several copper and critical-minerals companies experience market weakness.

The company is developing copper assets in Chile, giving it exposure to the long-term electrification and infrastructure theme. However, project-stage miners can be particularly sensitive to commodity prices, funding conditions and development timelines.

Its current chart pattern reflects weaker momentum despite longer-term interest in global copper demand.

Other resources names displaying similar pressure include Chalice Mining, Iluka Resources, Arafura Rare Earths and IperionX, showing that the decline extends across several mineral categories.

Paladin Energy joins weaker uranium charts

Paladin Energy has also appeared among the stronger downward trends despite continued long-term attention on nuclear power and uranium supply.

The companys Langer Heinrich operation in Namibia remains central to its operational performance, while its Canadian portfolio provides additional development exposure.

Nevertheless, uranium shares have recently faced technical weakness as the sector adjusts following earlier market strength. Deep Yellow and Bannerman Energy have also recorded weaker chart momentum, indicating a broader uranium-sector pullback rather than an isolated company movement.

Investors are likely to watch uranium prices, production updates and contracting activity when assessing whether sector momentum begins to stabilise.

How should technical signals be interpreted?

Technical analysis focuses on price behaviour rather than attempting to calculate the underlying value of a business.

An upward trend does not guarantee continued strength, while a downward trend does not mean a companys underlying operations have permanently deteriorated.

Unexpected announcements, commodity movements, capital raisings, regulatory changes and broader market events can quickly alter a chart structure.

Technical indicators are therefore commonly considered alongside financial statements, operational updates, valuation measures and industry conditions.

The latest ASX scans reveal a market divided between stronger energy and diversified business trends and weaker patterns across healthcare technology, defence and resources companies. Woodside Energy and Wesfarmers continue displaying relatively constructive momentum, while 4DMedical, DroneShield, Electro Optic Systems, Hot Chili and Paladin Energy remain under technical pressure. The contrast highlights the importance of monitoring both company-specific developments and broader sector rotation when interpreting Australian share-price trends.
