3 ASX 200 stocks smashing the benchmark this week

Investors sent these three ASX 200 stocks racing ahead of the benchmark this week. But why?

With just a few hours of trade left before Friday's closing bell, the S&P/ASX 200 Index (ASX: XJO) is up 2.5% for the week, with plenty of lifting help from these three surging ASX 200 stocks.

One this week's outperforming companies is a national energy provider, one develops and manages data centres, and the third produces building materials.

Which fast-rising stocks am I talking about?

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%.
