This was CNBC's live blog covering European markets.
European markets closed lower on Wednesday, losing momentum from earlier in the week.
The pan-European benchmark Stoxx 600 index closed 0.43% lower, losing the morning's gains. Tech stocks held on to an increase of 1.3%, while financial services dropped 1.9%.
The U.K.'s FTSE 100 snapped a five-day winning streak, falling into the red at the very end of the session to close 0.06% lower.
It was a similar picture stateside, with the S&P 500 and Dow Jones Industrial Average both lower while the tech-heavy Nasdaq Composite climbed on earnings from companies including Tesla.
Europe's markets had until now been buoyed by gains on Wall Street, where investors have been keeping a close eye on tech earnings along with mounting expectation that central banks in Europe will start cutting interest rates ahead of the U.S. Federal Reserve.
That has particularly benefited U.K. stocks, despite Bank of England Chief Economist Huw Pill pouring some cold water on the prospect of imminent cuts in a Tuesday speech.

UBS shareholders approve AT1 bond change, shares fall to two-month low
UBS shareholders on Wednesday afternoon approved changes to the bank's Additional Tier 1 (AT1) bond system, protecting them from the kind of wipeout suffered by Credit Suisse AT1 bondholders last year as the bank collapsed.
The change moves the AT1 bonds, a form of debt that can be converted when a bank's capital ratio falls below a certain level, to an equity conversion structure.
UBS had sought to make the debt instruments, also known as contingent convertibles or "CoCos," more appealing in the wake of the Credit Suisse bondholder losses. The writedown was criticised by some.
The Swiss bank faces greater capital requirements due to its increased size following its acquisition of former rival Credit Suisse, and as domestic regulators push to make those requirements even more stringent.
UBS raised $3.5 billion in November from its first AT1 bond sale since the takeover.
Shares of UBS were 2.8% lower at 4 p.m. in London at their lowest level since Feb. 29.
In a separate development, U.S. hedge fund Appaloosa filed a lawsuit in a New Jersey court accusing the former Credit Suisse — now absorbed into UBS — of misleading investors before $17 billion of its bonds were written down, Reuters reported.
The news was reported by Bloomberg overnight Tuesday.

Stocks on the move: ASM International up 12%, Evotec down 34%
Dutch semiconductor supplier ASM International topped the Stoxx 600 index in afternoon trade, up 11.8% at 3:40 p.m. in London.
In results published after the Tuesday close, the company reported higher revenue and net earnings, and raised its revenue forecast for the second quarter and the second half of 2024 as it said it expected a less extreme slowdown in China sales.
At the other end of the Stoxx, German drug company Evotec plunged 34% following the publication of its full-year 2023 results which showed an operating loss of 47.5 million euros, compared to 20.9 million euros operating profit the year before.
Evotec also announced the appointment of Christian Wojczewski as new chief executive officer from July, following the exit of longtime CEO Werner Lanthaler amid accusations of non-compliance with share trading disclosure rules.
Interim CEO Mario Polywka said the company's 2024 aim was to "refocus... on profitable growth."

UBS chair insists bank is not 'too big to fail'
UBS Group Chairman Colm Kelleher used the Swiss banking giant's Annual General Meeting on Wednesday to insist that the institution is "not too big to fail."
Kelleher added that the bank was "seriously concerned" about Swiss government proposals for additional capital requirements on several systemically important banks, including UBS. He argued such proposals would curb Switzerland's competitiveness as a financial center and increase European regulatory fragmentation.
"Trust cannot be regulated," he said in a speech.
In a separate interview with CNBC, Johan Torgeby, chief executive of Swedish bank SEB, said he agreed with Kelleher's argument on regulation.
"It is very clear that there is a worry overall about higher capital requirements," Torgeby told CNBC's "Street Signs Europe."
"You can't regulate trust, and trust is a personal point, comes from asking shareholders to depart from their hard-earned money, putting [it] into a bank like SEB, and then we lever that up. Often this is not well-understood, that the real capital provider of anything a bank does is its shareholders, and we need to remain and regain any potential trust that has been destroyed there," he said.

ECB policymaker says June rate cut might not be followed by more
A June interest rate cut from the European Central Bank might not be followed by others, depending on how inflation develops, a policymaker said Wednesday.
Joachim Nagel, president of Germany's Bundesbank, said that he would support a rate cut in June, if upcoming economic data increases the ECB's confidence that inflation would soon return back to the 2% target.
"However, such a step would not necessarily be followed by a series of rate cuts," he said in a speech at the DZ Bank Capital Markets Conference 2024. "Given the current uncertainty, we cannot pre-commit to a particular rate path."
Nagel also expressed caution about the outlook for inflation, saying that it looks persistent in the services sector, as it is driven by "continued strong wage growth." He also noted that core inflation remained high.
"I am not fully convinced yet that inflation will actually return to target in a timely and sustained manner," he said.
