American Marconi Wireless News - Tech optimism lifts stocks ahead of Fed update on rates

Investors also awaited the US Federal Reserve's decision on interest rates, scrutinising the accompanying statements for indications of a potential increase next month to cool inflation in the world's biggest economy.

Oil prices meanwhile rose around one percent, with the main international contract, Brent North Sea crude, remaining above $111 a barrel amid worries of renewed fighting between the United States and Iran.

European stock markets dipped, with London down 0.3 percent in midday trading ahead of the first budget from the Labour government under Prime Minister Andy Burnham.

"For now, the rally in tech stocks is impervious to the rising oil price and the risks posed by political elections across the world, budgets and the Federal Reserve meeting this evening," said Kathleen Brooks, research director at the trading group XTB.

Investors were also awaiting the final outcome of Israel's general election, a couple of days after Brazil's currency and stock market plunged following the surprise re-election of leftist President Luiz Inacio Lula da Silva.

But most of the focus was on the Fed, which "is set to hold rates steady but could signal the path to more hikes" that could weigh on corporate profits and growth, said Neil Wilson, an investor strategist at Saxo UK.

Also coming up on Thursday are earnings results from Amazon, Apple and Intel, which could shape investor optimism on artificial intelligence amid the huge spending in the sector.

After a slight wobble this month caused by fresh worries about the massive investments, potential profitability and debt levels, AI-linked firms were back in demand.

SK hynix, which has been at the forefront of the chip boom, revealed Wednesday that its third-quarter operating profit soared 632 percent to $62.8 billion thanks to explosive demand for its advanced semiconductors.

The report added to optimism surrounding the sector after Anthropic, the creator of Claude AI, said Monday that first-half revenue surged about 1,300 percent and flagged heavy capital spending ahead, fuelling enthusiasm ahead of an expected IPO next month.

That was followed Tuesday by Broadcom's deal with Citi, Blackstone and Morgan Stanley to form a $63 billion financing structure to build new computing capacity for Anthropic.

Shares in SK hynix soared almost 11 percent Wednesday and South Korean rival Samsung, which reports its earnings Thursday, added nine percent.

That pushed Seoul's Kospi index up more than six percent.

In Japan, the chipmaker Kioxia saw its shares jump nearly 14 percent, helping the Nikkei 225 to advance more than one percent.
