US stocks roar back as trade war fears fade; Dow jumps 2.84%

Stocks rose almost everywhere on Monday, reflecting optimism that the United States and China are set to begin negotiations on trade.

MSCI's world equity index, which tracks shares in 47 countries, rose 1.53 percent after touching its level since Feb. 9, stirred by expectations that U.S. Treasury Secretary Steven Mnuchin would try to reach an agreement with China.

Hope of a rapprochement abbreviated the markets' hangover about a trade war pitting the world's two largest economies against one another.

The Dow Jones Industrial Average rose 669.4 points, or 2.84 percent, to 24,202.6, the S&P 500 <.SPX> gained 70.29 points, or 2.72 percent, to 2,658.55 and the Nasdaq Composite added 227.88 points, or 3.26 percent, to 7,220.54. Each index turned in its best day of performance since August 2015. 

Global stocks tank most since Nov; Facebook data breach drags tech stocks

US stocks joined a broad decline in global equity markets on Monday as traders turned cautious ahead of the Federal Reserve's policy meeting this week and amid continuing concerns about the threat of a global trade war.

The Dow Jones Industrial Average fell as much as 425 during the session and ended won 335.60 points, or 1.35 per cent, at 24,610.91. The S&P 500 index lost 39.09 points, or 1.42 per cent, to 2,712.92 and the tech-heavy Nasdaq Composite index dropped 155.07 points, or 1.8 per cent, to 7,334.24.
MSCI's main 47-country world stock index fell 1.1 per cent in afternoon trading after European stocks dipped and benchmark US indexes declined. Global equities are on their worst run since November.
Facebook shock to tech stocks

At the same time, shares of Facebook Inc shed nearly 7 per cent after reports that a political consultancy that worked on US President Donald Trump's 2016 campaign gained inappropriate access to data on 50 million of the social network's users. That decline dragged other technology stocks, which have led the market higher over the last two years.
