The S&P/ASX 200 fell 1.7% this week as heavyweight sell-offs dragged the market lower into the thick of August earnings season. The move came despite the RBA holding the cash rate at 4.35% on Tuesday, with governor Michele Bullock warning another hike remains "quite possible" if inflation doesn't keep cooling. It also came against a positive lead from Wall Street, where the S&P 500 hit a fresh record high on a benign US inflation report, a reminder that local earnings, not offshore sentiment, are driving the market right now.
This week’s best performers
Cleanaway Waste Management (ASX:CWY) +13.87%
Austal (ASX:ASB) +13.54%
Helia (ASX:HLI) +11.79%
Cleanaway Waste Management (ASX:CWY) +13.87%
Australia's largest waste manager jumped after disclosing a conditional takeover proposal from EQT Infrastructure at $3.13 a share, valuing its equity at about $9.4 billion, well above an earlier unsolicited $3.00 approach from an unnamed rival. It's the standard playbook for a takeover target, with bidders offering a premium to win shareholder support, so the stock jumps toward the offer price the moment a deal is disclosed. Both proposals remain non-binding and conditional on due diligence and shareholder approval, so nothing is locked in yet.
Austal (ASX:ASB) +13.54%
The Australian shipbuilder rocketed 17% in a single session after revealing a non-binding offer from Hanwha Defence USA to acquire Austal USA for US$1.05 to 1.2 billion, leaving its core Australian operations untouched. The company also flagged an expected FY26 group EBIT loss of around $113 million on non-cash provisions at the US business. Austal's board will now weigh up any firm offer that emerges, with the strategic logic clear given Austal USA's foothold in the US naval industrial base.
Helia (ASX:HLI) +11.79%
The lenders mortgage insurance specialist rallied after surprising the market with a combined ordinary and special dividend alongside an ongoing share buyback program, a signal it's sitting on more capital than it currently needs. The catch is the payout lands against softer underlying earnings and structural pressure on new mortgage insurance demand, as government deposit schemes and lenders' own self-insurance options chip away at Helia's addressable market. It's a good payday now, but the real question is whether Helia can keep selling enough new policies to fund the next one.
This week’s worst performers
Arena REIT (ASX:ARF) -29.88%
4DMedical (ASX:4DX) -13.74%
HomeCo Daily Needs REIT (ASX:HDN) -10.47%
Arena REIT (ASX:ARF) -29.88%
The childcare and healthcare property trust (REIT) tumbled after major tenant Edge Early Learning missed its August rent payment and requested deferrals as part of a corporate restructure, with Edge accounting for 14% of Arena's rental income. Arena has delayed its FY26 results while it works through the fallout. Surprisingly, Jarden still rates the stock a buy, arguing even a worst case where Edge pays nothing in FY27 would still value Arena at $2.60 a share, well above where it's currently trading at $2.30 a share.
4DMedical (ASX:4DX) -13.74%
The medical imaging company slipped further after a fresh batch of shares from exercised options hit the market, adding to the total share count and reviving dilution worries. The stock is now down almost 50% since its April high, extending a pullback despite a year that had earlier seen it surge 670% on growing US commercial momentum. FY26 results land August 27, the next real test of whether that commercial story is translating into numbers that justify a re-rate.
HomeCo Daily Needs REIT (ASX:HDN) -10.47%
The convenience retail trust fell despite posting yearly funds from operations, the cash a REIT actually generates from its properties, of $187.1 million and keeping payouts to unitholders steady at $0.086 a unit. The catch is the unit price is trading well below $1.56, the estimated value of the trust's underlying properties per unit, meaning the market is pricing it below what its assets are technically worth.
