Big losses end stocks’ rocky week

NEW YORK — Wall Street capped a turbulent week of trading Friday with the biggest weekly loss since March as traders fret over rising trade tensions between Washington and Beijing and signals of slower economic growth.

The latest wave of selling erased more than 550 points from the Dow Jones Industrial Average, bringing its three-day loss to more than 1,400. For the week, major indexes are down more than 4 percent.

Worries that the testy U.S.China trade dispute and higher interest rates will slow the economy has made investors uneasy, leading to volatile swings in the market from one day to the next.

On Monday, news that the U.S. and China had agreed to a 90-day truce in their escalating trade conflict drove stocks sharply higher, adding to strong gains the week before. The next day, as doubts mounted over the likelihood of a swift resolution to the trade dispute, stocks sank. On Friday, another early rally faded into another sharp drop.

“We’re in a market where investors just want to sell any upside that they see,” said Lindsey Bell, investment strategist at CFRA. “The volatility we’ve seen the last couple of weeks has been pretty extreme in both directions.”

The S&P 500 index fell 62.87 points, or 2.3 percent, to 2,633.08. The index has ended lower three out of the last four weeks. The Dow dropped 558.72 points, or 2.2 percent, to 24,388.95.

The Nasdaq composite slid 219.01 points, or 3 percent, to 6,969.25. The Russell 2000 index of small-company stocks gave up 29.32 points, or 2 percent, to 1,448.09.

The S&P 500 and Dow are now in the red for the year again. The Nasdaq was holding on to a modest gain.

Volatility has gripped the market since early October, reflecting investors’ worries that the Federal Reserve might overshoot with its campaign of rate increases and hurt U.S. economic growth.

Traders also fear that a prolonged trade dispute between the U.S. and China could crimp corporate profits and that tariffs will raises costs for businesses and consumers. Uncertainty over those issues helped drive the market’s sell-off this week.

“The Fed has taken the punch bowl away in getting back to rates where they are today,” said Doug Cote, chief market strategist for Voya Investment Management. “We’re also going to get back to more normal volatility.”
