The S&P/ASX 200 Index (ASX: XJO) is down 0.7% in early afternoon trade on Thursday, but that's not keeping these four ASX 200 shares from leaping to new 52-week highs.

Two of the outperforming companies operate in the healthcare space, one is a national insurer, and the fourth operates Australia's biggest airline.

(You can probably guess that last one.)

Here's what's happening.

Four ASX 200 shares hitting new one-year highs

The first ASX 200 share notching new 52-week plus highs today despite the slumping market is QBE Insurance Group Ltd (ASX: QBE).

Shares in the insurance giant are up 1.0% at the time of writing, trading for $20.35 after touching a high of $20.40. That puts the QBE share price up 29.5% since this time last year, its highest level since May 2010.

Atop the strong run over the last year, QBE shares also trade on a partly franked 3.5% trailing dividend yield.

Also marching into new 52-week high territory today is ASX 200 share Pro Medicus Ltd (ASX: PME).

Shares in the health imaging company are currently flat at 268.08 after hitting a milestone high of $272.50 in early trade today. That's not only a new one-year high, but a new all-time high for the Pro Medicus share price and sees the Pro Medicus share price up 165% in 52 weeks.

Pro Medicus shares also trade on a slender, fully franked 0.2% trailing dividend yield.

Which brings us to the third ASX 200 share hitting new 52-week plus highs today amid the wider market retrace, Qantas Airways Ltd (ASX: QAN).

Shares in the Flying Kangaroo are up 1.3% in early afternoon trade today, at $9.50 after touching a high of $9.54 around midday. That puts the Qantas share price up 76.9% over the past full year. And in a sign that Qantas has truly flown past its pandemic stock meltdown and post-pandemic reopening hiccups, this also marks a new all-time high for the airline.

Qantas has yet to reinstate dividends, which were suspended in 2020. But 2025 could see Qantas dividends make a comeback. The airline has been benefiting from the ongoing rebound in domestic and international travel demand, along with lower-than-expected jet fuel costs in 2024.

Moving on to the fourth ASX 200 share hitting 52-week highs today, we have Telix Pharmaceuticals Ltd (ASX: TLX).

Shares in the diagnostic and therapeutic product developer are up 0.2% at the time of writing at $26.88 each. This puts the Telix share price up 141.1% in 12 months.

In earlier trading today, the Telix share price climbed to a fresh high of $27.29. And like Qantas and Pro Medicus, this means Telix shares have traded at an all-time high today.
