Wall Street gained ground on Friday in a broad-based rally as investors were heartened by news that Washington would move to temporarily end the longest US government shutdown in history.

All three major US stock indexes advanced, with the Dow and the Nasdaq eking out their fifth straight weekly gains. But the S&P 500 posted its first weekly loss of the year, snapping a four-week run.

The indexes backed off their highs after President Donald Trump confirmed he and lawmakers agreed to advance a three-week stop-gap spending plan to reopen the government.

Investor sentiment had faltered in recent days in the face of revived jitters related to the shutdown and the prolonged US-China tariff spat.

‘As some of these uncertainties in the market start to diminish we’ll get a clearer picture as to where things are headed,’ said Charlie Ripley, senior market strategist for Allianz Investment Management in Minneapolis. ‘And today’s news of the ending of the government shutdown certainly alleviates some of that overhang.’

‘But most likely some uncertainty will linger as this is only a temporary measure to fund the government for now,’ Ripley added.

Among these uncertainties, the ongoing trade dispute between the United States and China continues to worry investors.

With the World Economic Forum in Davos, Switzerland, nearing its conclusion, business leaders have expressed worries over the tariff battles, saying they are ‘fed up’ with Trump’s policies.

An escalation of the US-China trade war would sharpen the global economic slowdown already under way, according to a Reuters poll of hundreds of economists worldwide.
