Two ASX 200 tech shares dropping to fresh one-year-plus lows
The first company making this rather ignominious list today is WiseTech Global Ltd (ASX: WTC).
Shares in the logistics software solutions company are down 5.1% in late morning trade today, changing hands for $36.42 each. That sees the WiseTech share price down 55.2% over 12 months and trading at its lowest level since June 2022.
WiseTech shares have come under pressure over the past months amid increasing concerns that artificial intelligence (AI) could soon be able to deliver much of the same services the company offers at materially cheaper costs.
Which brings us to the second ASX 200 share trading at 52-week-plus lows today, Xero Ltd (ASX: XRO).
Shares in the business and accounting software provider are down 4.9% at the time of writing, trading for $69.25 apiece. This puts the Xero share price down 55.3% over 12 months and trading at its lowest level since November 2022.
Like WiseTech, Xero shares are facing negative investor sentiment amid the rapid rise of AI technologies.
Two ASX 200 healthcare shares sinking to new 52-week lows
Moving on to the healthcare space, we have Sigma Healthcare Ltd (ASX: SIG).
Shares in the retail pharmacy giant, which merged with Chemist Warehouse in 2025, are down 0.6% today, trading for $2.605 each. That sees the Sigma Healthcare share price down 9.6% in a year and at its lowest level since December 2024, prior to the merger.
ResMed Inc (ASX: RMD) shares are also doing it tough.
Shares in the sleep disorder treatment company are down 1.3% today, changing hands for $31.925 each. That puts this ASX 200 share down 8.7% over 12 months and trading at its lowest level since August 2024.
As for the property development giant…
Interest rates may be biting
Stockland Corp Ltd (ASX: SGP) shares join our list of stocks slumping to new one-year-plus lows today.
Shares in the diversified property development company are down 1.4% on Monday, trading for $4.20 each. That puts this ASX 200 share down 14.3% over 12 months and trading at its lowest level since January 2025.
Like many real estate companies, Stockland shares have faced headwinds amid resurgent global inflation and expectations of higher interest rates to come. Real estate stocks tend to perform better in low and falling interest rate environments.
