It's been a huge week on the S&P/ASX 200 Index (ASX: XJO) with a raft of top ASX 200 stocks reporting full-year and half-year earnings results.
As investors sent some stocks shooting higher and others plunging on the heels of those results, the benchmark Aussie index is up a modest 0.2% for the week, with just a few hours of trade left before Friday's closing bell.
Below we look at three ASX 200 stocks that have surged 16% to almost 24% this week as their results surprised to the upside.
ASX 200 stocks leaping on results
First up, we have lithium miner Pilbara Minerals Ltd (ASX: PLS).
Pilbara Minerals shares closed last Friday at $2.11. At the time of writing, they are changing hands for $2.44 apiece, which puts this ASX 200 stock up 15.6% over the week.
The miner kicked off the week with a bang, releasing its FY 2025 results on Monday.
Among the highlights, Pilbara achieved record lithium (spodumene concentrate) production of 754,600 tonnes over the 12 months, up 4% from FY 2024. Lithium sales of 760,100 tonnes were up 7%.
With shares still down sharply from one year ago, investors looked past Pilbara Minerals' statutory loss after tax of $196 million and eyed a potential recovery in the year ahead.
"The long-term fundamentals for lithium remain intact. Current prices are not sufficient to incentivise new supply, which points to potential tightness ahead," Pilbara Minerals CEO Dale Henderson said.
Moving on to the second ASX 200 stock smashing the benchmark returns this week following earnings results, we have jewellery retailer Lovisa Holdings Ltd (ASX: LOV).
Lovisa shares closed last Friday trading for $35.23. Shares are currently trading for $43.23, up 22.7% for the week.
Lovisa shares closed up 13.2% on Wednesday when the company released its FY 2025 report.
Investors piled into the stock after Lovisa reported a 14.2% year-over-year increase in sales to $798.1 million. And with the gross margin up 1%, the jewellery company achieved a 4.8% lift in net profit after tax (NPAT) to $86.3 million.
Over the 12 months, Lovisa also opened 131 net new stores.
Which brings us to…
Leading the pack
The best performing ASX 200 stock for the week on my list is automotive retail group Eagers Automotive Ltd (ASX: APE).
Eagers shares closed last Friday at $21.99. In late afternoon trade today, shares are swapping hands for $27.22. That sees the Eagers share price up an impressive 23.8% for the week.
The Eagers share price gained 12.0% on Thursday after the company reported its half-year results (H1 2025).
Investor enthusiasm was on display after the company reported an 18.9% year-over-year increase in revenue to $6.5 billion. And on the bottom line, Eagers' net profit was up 8.8% from H1 2024 to $134 million.
