CSL Ltd (ASX: CSL)
The CSL share price is $97.98, up 0.7% today.
Over the past month, this ASX 200 healthcare share has fallen another 30%.
Jarden downgraded CSL shares from a buy to hold rating on Tuesday.
The broker slashed its 12-month price target from $244 to $191.
This still suggests major potential upside of 95% over the next 12 months.
GrainCorp Ltd (ASX: GNC)
The Graincorp share price is $5.23, down 2.9% and down 20% over the past month.
Morgans downgraded this ASX 200 agribusiness share after the company released its 1H FY26 results.
The broker moved to a hold rating with a $5.62 target, implying 7.5% upside ahead.
In a note, the broker said:
GNC's 1H26 result was weak but broadly in line with consensus at the NPAT level. Business unit performance was stronger for Agribusiness but materially weaker for Nutrition & Energy given a one-off derivate timing issue.
GNC reported a significantly larger than expected cash outflow and its core cash position was also lower than expected.
The era of special dividends now appears to be over. GNC reiterated its FY26 earnings guidance.
Looking ahead to FY27, Morgans said dry El Nino conditions and cost pressures would likely lead to a "much smaller crop".
GNC's strategic assets are worth materially more than its current share price.
However, given earnings look set to decline again in FY27, the stock is lacking share price catalysts, and we move to a HOLD recommendation.
Healius Ltd (ASX: HLS)
The Healius share price is 37 cents, down 1.4% on Friday.
Over the past five trading days, this ASX healthcare stock has fallen 27%.
Healius shares were smashed after the company issued an FY26 earnings downgrade.
RBC Capital downgraded Healius shares to a sell rating this week.
The broker slashed its 12-month price target from 75 cents to 35 cents.
This indicates the stock is fully priced.
Amotiv Ltd (ASX: AOV)
The Amotiv share price is $6.25, up 0.2% today.
Over the past six months, this ASX consumer discretionary share has fallen 30%.
Citi downgraded Amotiv shares to a hold rating on Tuesday.
The broker slashed its price target from $9.30 to $6.70, indicating limited upside ahead.
Mach7 Technologies Ltd (ASX: M7T)
The Mach7 Technologies share price is 28 cents, up 1.8% today.
In the calendar year to date, this ASX healthcare share has tumbled 59%.
Canaccord Genuity downgraded Mach7 shares to a hold rating with a 27-cent target on Tuesday.
This suggests the stock is fully priced.
