The All Ordinaries Index (ASX: XAO) is down 1.6% today amid ongoing global tariff uncertainties, but three ASX shares are shrugging off the market worries to notch new 52-week plus highs. 

Here's what happening.

ASX shares posting new 52-week highs

Up first we have Farm Pride Foods Ltd (ASX: FRM).

Shares in the Aussie egg company are up 4.8% to 22 cents in very thin trade today.

This puts the ASX share up 83.3% in a year and trading at its highest levels since February 2022.

At the company's half-year results (H1 FY 2025), reported on 26 February, Farm Pride reported an after tax profit of $1.6 million, up from a loss of $920,000 in H1 FY 2024. Management noted this marked the first half-yearly profit the company had achieved since the financial year ending 30 June 2018.

The second ASX share hitting new 52-week plus highs despite today's sinking market is Australian Agricultural Co Ltd (ASX: AAC).

Shares in the Australian beef producer are up 0.3% today, changing hand for $1.535 apiece.

While that's a slender intraday gain, it sees the Australian Agricultural share price up 9.6% in a year and trading at the highest level since June 2023.

The last price-sensitive news from the ASX share was the release of its half-year results (H1 FY 2025).

Australian Agriculture reported a 17.0% year on year increase in revenue to $195.5 million and a statutory net profit after tax of $23.6 million, up from a loss of $105.5 million in H1 FY 2024. However, with operating profit margins sliding from 18.1% to 10.3%, operating profits fell 32.9% year on year to $20.2 million.

Rounding off the list of ASX shares shrugging off today's market sell-down to hit new 52-week highs is New Murchison Gold Ltd (ASX: NMG), formerly known as Ora Gold.

The New Murchinson Gold share price is up 7.7% to 1.4 cents a share, giving it a market cap of just over $108 million. This puts the share price up 40% in a year.

The ASX share closed up 33.3% on Monday following a promising exploration update from the Garden Gully Gold Project in Western Australia.

Commenting on the exploration results earlier this week, New Murchison Gold CEO Alex Passmore said:

While we caution that assays are awaited …we are pleased to report the strong visual indications of mineralisation in a key extensional area for the Crown Prince resource.
