Expert's verdict on 3 ASX 200 shares (2 have doubled in value and the other has lost 29%)

Two of these stocks were the best performers of their sectors in FY25. Should you buy, hold, or sell?

One of these S&P/ASX 200 Index (ASX: XJO) shares soared 135% in FY25 and was the fastest riser of the healthcare sector.

Another share rose by 121% and was also the best performer of its market sector for FY25 — this time, it was technology.

The third ASX 200 share crumbled 29% in FY25. Is it time to buy the dip, or is this coal stock a dud?

Paterno's verdict on 3 ASX 200 shares

Sigma Healthcare Ltd (ASX: SIG)

The Sigma Healthcare share price leapt 135% on the back of the blockbuster Chemist Warehouse merger to finish FY25 at $2.99.

This made it the No. 1 stock among the 5 best-performing healthcare shares of FY25.

The merger became official in February.

Paterno says Chemist Warehouse's 1H FY25 trading update highlighted continuing robust operating momentum.

He noted like-for-like sales were up 10.3% and the company opened 19 new stores

Chemist Warehouse reported strong earnings and robust sales growth amid new supply agreements and the implementation of operational cost efficiencies.

But he's cautious on Sigma Healthcare shares from here and rates the stock a hold.

Paterno said:

We retain a positive stance on the quality of the Chemist Warehouse business, but downgrade Sigma to a hold on valuation grounds.

Technology One (ASX: TNE)

TechnologyOne was the stand-out among the 5 best-performing ASX 200 tech shares of FY25, ripping 121% to $41.01 by 30 June.

During the year, stock in this enterprise software company reached a record high $42.88 on 6 June.

Can it keep going?

Paterno is cautious and rates this ASX 200 tech share a hold.

He said:

The company's transition to a software-as-a-service operating model in October 2022 continues to deliver results from new contract wins, including the Islington London Borough Council.

Annual recurring revenue) in the United Kingdom was up 50 per cent in the first half of fiscal year 2025 when compared to the prior corresponding period.

Total annual recurring revenue was up 21 per cent. Profit after tax was up 31 per cent.

The company has upgraded full year profit growth to between 13 per cent and 17 per cent.

Whitehaven Coal (ASX: WHC)

The Whitehaven share price fell 29% over FY25 to close at $5.43 per share on 30 June.

Is it a bad stock to buy, or a beautiful 'buy the dip' opportunity?

The ASX 200 coal share is a buy, says Paterno.

He explains:

We recently visited WHC's metallurgical coal mines in Queensland.

Management has made good progress in improving productivity, which gives us confidence the company will meet our growth forecasts amid decreasing unit costs.

We expect this to drive strong underlying free cash flow in fiscal year 2026, despite recent softness in coal markets.

The recent discount to our fair value estimate provides an attractive entry point for investors with a positive view on the medium term outlook for metallurgical coal.
