Cochlear Ltd (ASX: COH)
Cochlear shares were smashed this week after the hearing implant device maker downgraded its earnings guidance.
The company now expects an FY26 underlying net profit of $290 million to $300 million, down from $435 million to $460 million.
Cochlear cited capacity constraints at hospitals, falling consumer confidence globally, and cancelled procedures in the Middle East.
The company said:
Consumer sentiment has declined in key markets, reaching historic lows in the US.
The decline appears to be affecting discretionary healthcare decisions in the adults and seniors segment, adding to demand uncertainty in the near term.
On top of that, industrial action in Italy and Spain has delayed procedures, and China has lowered its reimbursements to patients.
Morgan Stanley upgraded Cochlear shares to a hold rating following a 39% fall in the share price on the day of the news.
The broker slashed its 12-month price target from $194 to $119.
The Cochlear share price hit a new 52-week low of $95.81 yesterday.
Over the past 12 months, the ASX 200 healthcare share has dropped 64%.
Treasury Wine Estates Ltd (ASX: TWE)
Treasury Wine Estates shares rose sharply this week after the company announced a new regional operating model to raise efficiency.
This ASX 200 wine share has been on the nose with investors and fell to a multi-year low of $3.34 last month.
The company's new model is part of a global transformation program called TWE Ascent.
Treasury Wine will operate four new regional divisions: The Americas, Australia and New Zealand (ANZ) and Europe, Greater China, and Emerging Markets (Rest of Asia, Middle East and Africa).
Treasury Wine Estates CEO Sam Fischer said:
We are reshaping TWE to drive clearer accountability for performance and to enable faster, more market-connected decision-making as a foundation for consistent depletions growth.
Fischer added:
Combining the deep local insight of our in-market teams with the scale and expertise of our global functions will step change in-market execution, whilst retaining our enhanced focus on Penfolds and other priority luxury brands.
Citi likes the look of the plan, and upgraded Treasury Wine Estates shares to a hold rating as a result.
The ASX 200 wine share rose 17% to $4.73 on the day of the announcement. Citi's 12-month price target is $4.25.
Over the past 12 months, the ASX 200 wine share has tumbled 48%.
