ASX 200 stocks leaping higher this week
The first outperforming ASX 200 stock on my list for the week is NextDC Ltd (ASX: NXT).
Shares in the data centre operator and developer closed last Friday trading for $12.71. At time of writing, shares are changing hands for $14.28 each. This sees the NextDC share price up 12.4% for the week.
There was no fresh news out from the company this week. But NextDC shares look to have benefited from a broader rebound in US and Aussie tech stocks, following the sharp sell-off last week.
Moving on to the second fast-rising ASX 200 stock this week we have AGL Energy Ltd (ASX: AGL).
Shares in the Aussie energy provider closed last week trading for $8.95. Shares are currently trading for $10.16 each. This puts the AGL share price up 13.6% for the week.
Most of those gains were delivered on Wednesday. AGL shares closed up 11.8% on the day following the release of the company's half year results (H1 FY 2026).
AGL reported underlying earnings before interest, taxes, depreciation and amortisation (EBITDA) of $1.09 billion for the six months, in line with H1 FY 2025.
While underlying net profit after tax (NPAT) was down 6% year on year to $353 million, management fine-tuned their FY 2026 underlying EBITDA guidance to the range of $2.02 billion to $2.18 billion. Full year NPAT guidance was narrowed to $580 million to $680 million.
Management also declared a fully franked interim dividend of 24 cents per share, up 4.3% from last year's interim payout. AGL shares trade on a fully franked 4.8% dividend yield.
Which brings us to…
Also racing higher
James Hardie Industries PLC (ASX: JHX) shares also raced ahead of the benchmark this week.
Shares in the building materials company closed last week trading for $32.46 and are currently swapping hands for $36.68. That sees this ASX 200 stock up 13.1% for the week.
James Hardie shares closed up 11.8% on Wednesday following the release of the company's third quarter results.
Highlights included a 30% increase in net sales for the three months to US$1.24 billion.
Adjusted EBITDA of US$330 million was up 26%.
