This is CNBC's live blog covering European markets.

European markets closed higher Thursday as the European Central Bank's updated inflation forecast put the 2024 rally back on track.

The pan-European Stoxx 600 provisionally closed 1.05% higher at 503.45 points after surpassing the key 500 level for the first time during the session.

The European Central Bank held interest rates steady at a record 4%, as it revised its forecast for inflation in 2024 to 2.3% from 2.7%.

It also said euro zone growth would be weaker than previously expected this year, at 0.6%.

Markets, which had already zeroed in on rate cuts beginning in June, took the updated macro forecasts as a further sign for that month.

ECB President Christine Lagarde meanwhile said market pricing "seems to be converging better" with the ECB's own view. 

Thursday's news "all but seals the deal that the bank will start easing policy at its June meeting, provided we don't see a blow up in both inflation and wages in the interim," Matthew Ryan, head of market strategy at Ebury, said. "This is now almost fully priced in by swap markets following today's announcement."

Elsewhere, Asia stocks rose after comments from U.S. Federal Reserve Chair Jerome Powell on Wednesday. He reiterated his stance that while the central bank could start cutting rates, it was "not immediately ready."

U.S. stocks were also higher in morning trade as investors digested the monetary policy outlook.

Europe stocks close higher

Europe's Stoxx 600 gained 1.05% Thursday, closing above the psychological level of 500 for the first time ever, as the European Central Bank's latest monetary policy meeting fueled bets on a June rate cut.

Technology stocks rallied 2.26% as health care gained 2.3%.

Germany's DAX and France's CAC 40 were both around 0.7% higher, while the U.K.'s FTSE 100 ended the session up 0.17%.

'Exogenous shocks’ could threaten IPO market, Raymond James says

External shocks, such as as geopolitical events or still restrictive monetary policy, could undermine growing confidence in the IPO market, investment firm Raymond James said Thursday.

"Exogenous shocks remain a real threat," Sunaina Sinha Haldea, global head of private capital advisory, told CNBC. She added that technical flows — or sudden outflows of investment from one market to another — also risk causing disruption even as money begins to return to the market.

UK house prices rise as cautious confidence returns

U.K. house prices increased for the fifth consecutive month in February, in a sign that momentum is returning to the lacklustre real estate market, new data showed Thursday.

The average U.K. house price rose by 0.4% in February, marking an increase of 1.7% year-on-year, according to Halifax House Price Index.

Halifax Mortgages director Kim Kinnaird said that the data suggests cautious confidence is returning to the market in anticipation of a reduction in interest rates later this year.

"These figures continue to suggest a relatively stable start to 2024 and align with other promising signs of increased housing activity, such as mortgage approvals," she said.

CNBC Pro: How can foreign investors cash in on India’s growth? Here are the ETFs and stocks to buy

India's economic prospects are shining bright, attracting global investors eager to capitalize on the country's immense growth potential.

The International Monetary Fund expects India's real gross domestic product (GDP) to expand by 6.5% in 2024. 

However, tapping into these opportunities as a foreign investor is not as straightforward as buying shares listed on the Indian stock exchanges. Limits on foreign ownership, complex tax implications, and corporate governance concerns create barriers.

CNBC Pro: Analysts love these value stocks, giving 4 more than 30% upside

Many growth stocks are becoming expensive, prompting some investors to turn to value stocks.

"The S&P 500 at 5,075 with expected earnings growth of 10% for 2024 gives us $243 a share and puts us at 21X earnings - its pricey, plain, and simple," said Brian Szytel, senior managing director of The Bahnsen Group, in late February. The S&P 500 closed around 5,078 on Tuesday.

He said he wouldn't own the index at that level. "I would however, own parts of the market shift to more value-oriented names and believe that rotation that started in 2022 from growth to value will resume. This is a time to earn 'carry', income, and dividends," he said.

Those interested in value stocks can consider the following from CNBC Pro's screen of the Vanguard Value ETF. All have 20% or more upside and a buy rating of at least 50%, with the screen showing their current and 5-year average dividend yields.
