Global stock markets edged higher Thursday, buoyed by firmer prices on Wall Street, but investors remained cautious overall amid lingering uncertainty over President Donald Trump's policy agenda and the outlook for Britain's Brexit negotiations with the European Union, traders said.
"Stocks are still in a bit of a holding pattern with traders lacking a bit of conviction," said Jasper Lawler at London Capital Group.
"A positive open in the US, helped by further recovery in crude oil prices improved sentiment in European markets."
London's FTSE-100 ended the session little changed, while Frankfurt's DAX 30 and the CAC 40 in Paris both added around 0.4 percent.
The day before, markets had barely flinched when Britain formally notified the EU of its intention to quit the 28-nation bloc, as investors had largely priced in "Brexit" since last year's referendum, dealers said.
But there would be downside risks if the negotiations -- expected to last at least two years -- turned nasty, analysts said.
Nevertheless, for the time being, the situation was "very calm on the stock markets at the end of the quarter," said analysts at French brokerage Aurel BGC.
"Indices remain at very high levels, but activity is very low."
Earlier in Asia, stock prices had fallen as Chinese authorities tightened liquidity in the financial system of the world's second-largest economy.
US growth in the fourth quarter was nudged up to 2.1 percent from the prior 1.9 percent estimate, according to official government data.
Back in Europe, with Brexit negotiations likely to drag on for at least two years, investors may now focus on upcoming elections in a number of countries, such as the presidential elections in France, dealers said.
"In the event that support for Marine Le Pen -? the leader of the far right-wing National Front party -? increases, so too will anxiety among market participants, and serious question marks will be raised about the future of the whole EU project."
Given this uncertainty, the euro could come under pressure in the coming weeks and months, the analyst suggested.
