This was CNBC's live blog covering European markets.

European markets closed lower on Wednesday as investors assessed a fresh batch of corporate earnings, regional growth data and the U.K. budget.

The pan-European Stoxx 600 provisionally closed 1.2% lower, with sectors and major bourses in negative territory. Technology stocks led the losses, down 2.4%.

Flash data published Wednesday showed that the euro zone economy grew 0.4% in the third quarter of 2024, above the 0.2% rise expected by economists polled by Reuters.

In the U.K., Finance Minister Rachel Reeves said the budget would raise taxes by £40 billion ($51.86 billion) in a bid to plug what the Labour government has described as a "black hole" in the country's public finances. Follow our budget live blog here.

Meanwhile, it's another busy day of earnings and business updates, with a host of companies scheduled to post their latest results.

Reporting in the early hours, Swiss bank UBS posted a large profit beat, after completing its first wave of client migrations following its integration of collapsed domestic rival Credit Suisse.

Asia-Pacific markets closed mostly lower on Wednesday despite key Wall Street benchmarks rising in the previous session, with the Nasdaq Composite closing at a record high as tech stocks gained.

U.S. stocks were little changed Wednesday as traders digested a flurry of earnings and looked toward further reports from major technology companies.

UK banks rally after Labour government delivers October budget

Shares of Britain's banks rose on Wednesday afternoon after it appeared the Labour government's first budget in nearly 15 years would stop short of imposing a levy on the sector's profits.

Among a litany of tax rises announced to allow for more borrowing to boost investment, U.K. Rachel Reeves did not mention whether the government had plans to raise taxes on the country's banks.

Shares of Barclays rose 3% on the news, with NatWest up more than 2% and Lloyds trading 0.3% higher.

Britain confirms major change to fiscal rules

U.K. Finance Minister Rachel Reeves confirmed a move to target public sector net financial liabilities (PSNFL) as a measure of the country's debt in a move designed to free up billions of pounds for long-term investments.

Reeves said the move to target PSNFL, rather than public sector net debt, means she will be left with £15.7 billion ($20.4 billion) of headroom at the end of the Office for Budget Responsibility's forecast period.

That's "much lower than expected," said Paul Johnson, director of the Institute for Fiscal Studies, an influential think tank.

The PSNFL measure takes in a wider account of the government's balance sheet, including financial assets and liabilities, than public sector net debt.

Reeves said last week that she intended to change the country's fiscal rules but had stopped short of specifying exactly what the new so-called investment rule would change.

German gross domestic product unexpectedly rises 0.2% in the third quarter

The German economy grew by 0.2% in the third quarter of 2024 when compared to the previous three months, the country's statistics office Destatis said Wednesday in a preliminary gross domestic product data release.

Analysts polled by Reuters had expected a 0.1% decline.

Destatis also revised the GDP figures for the second quarter lower to a 0.3% contraction, down from a 0.1% dip that was previously reported.

The growth in the third quarter means Germany has skirted a technical recession — which is marked by two consecutive quarters of contraction — for now. Germany's GDP had increased 0.2% in the first quarter of the year.

UK clothing retailer Next says annual profit on track to exceed £1 billion

U.K. clothing retailer Next on Wednesday forecast annual profit in excess of £1 billion ($1.3 billion) as it raised its full-year guidance on the back of improved third-quarter sales.

Next said full-price sales in the August to October period rose 7.6% from last year, comfortably topping the firm's guidance of a 5% jump in quarterly sales.

The firm attributed the robust performance to the early arrival of colder weather this year, in contrast to an unusually warm September and early October in 2023.

Next upgraded its profit guidance for the full-year to £1.005 billion, up from its previous forecast of £995 million.

Luxury carmaker Aston Martin posts smaller-than-expected quarterly loss

Britain's Aston Martin posted a smaller-than-expected third-quarter loss, with the luxury carmaker saying it remains on track to deliver on its revised full-year guidance as supply chain disruptions are "proactively managed."

"Improved financial and operational performance in Q3 2024, demonstrates our strategy's effectiveness," Aston Martin CEO Adrian Hallmark said in a statement.

CNBC Pro: 'Absurdly cheap': Bottom-up investor names Japan sectors — and stocks — to invest in right now

Japanese markets have made steady gains this week - and one bottom-up investor sees potential for it to advance even further.

"When we look at Japan — it's very difficult not to be bullish on stocks. Because even companies that are struggling in terms of earnings have depressed valuations and may not see a drastic fall in their stock price even if earnings are weak," Mio Kato, founder of capital markets firm LightStream Research, said.

"When we look at the valuations of a lot of companies, they look absurdly cheap," he added.

Kato also revealed sectors - and stocks - he is betting on right now.

The dollar's value could wane under a Trump presidency, investor warns

Some investors believe that under a Trump presidency, higher interest rates and inflation could lead to a more expensive dollar. But Erik Knutzen, co-chief investment officer of Neuberger Berman's Multi-Asset Strategies, says that the dollar could actually decline under a Trump administration.

"The dollar did rally through the end of the year after the surprise win of Trump in 2016, but the dollar declined in value for 2017 when Trump was enacting the policies that were supposedly going to be more inflationary and cause higher interest rates," he said on CNBC's "The Exchange" on Tuesday afternoon. "Trump and his cohort actually would like to see a weaker dollar to support the American economy. Yes, the dollar may have some short-term impetus, but frankly you could probably fade that trade if Trump is not elected."

Knutzen added that the dollar will probably weaken in the near term in the scenario that Trump loses the November election.
