   -- Crude oil rises after OPEC deal 
 
   -- Dow rises after eight straight losses 
 
   -- Biggest weekly outflows from EM equities since 2016 

The Dow Jones Industrial Average rose Friday but posted its biggest one-week slide since March as escalating tariff tensions drove investors out of companies they fear could suffer under tighter trade conditions.

Stocks wobbled throughout the week, with shares of industrial firms, agricultural companies and auto makers sliding as investors feared global trading relations were becoming increasingly fractured.

President Donald Trump asked his administration Monday to identify an additional $200 billion of Chinese goods that would be penalized with tariffs. He then threatened Friday to impose a 20% tariff on European cars after the European Union began imposing duties on U.S. products ranging from bourbon whiskey to Harley-Davidson motorcycles.

The moves contributed to unease among investors, who worry that such fractious approaches could hinder global growth at a time when many already believe that economic momentum is fading.

The Dow industrials fell eight straight sessions through Thursday -- notching its longest streak of declines in more than a year. As investors broadly shed risk, investors withdrew the biggest weekly amount from emerging-market equities, financials and investment-grade bond funds since 2016, according to Bank of America Merrill Lynch.

"We're starting to see some corporate impact to some of the rhetoric coming out of Washington," said Barbara Reinhard, head of asset allocation at Voya Investment Management. "Potentially targeting the auto sector has a far greater economic impact than anything that has been done so far."

The Dow industrials rose 119.19 points, or 0.5%, to 24580.89 Friday but slid 509.59 points, or 2%, for the week.

The S&P 500 added 5.12 points, or 0.2% to 2754.88 and fell 24.78 points, or 0.9% for the week, while the Nasdaq Composite edged down 20.13 points, or 0.3%, to 7692.82 and lost 53.56 points, or 0.7%, for the week.

Stocks got a boost Friday from energy shares, although they weren't enough to offset broad declines throughout the week from other sectors.

Dow component Chevron rose $2.51, or 2%, to $125.10 and Exxon Mobil added $1.69, or 2.1%, to $81.38 after members of the Organization of the Petroleum Exporting Countries agreed to a deal to join other big producers in boosting oil production by about 600,000 barrels a day.

The move came as a relief to investors who had been expecting the cartel to decide to boost output even further, sending U.S. crude for August delivery up 4.6% to $68.58 a barrel -- its biggest one-day percentage gain since 2016.

Industrial shares in the S&P 500 rose Friday but posted weekly declines, with Caterpillar down $10.08, or 6.7%, to $139.94 for the week and Boeing losing $18.97, or 5.3%, to $338.91 over five sessions.

Elsewhere, the Stoxx Europe 600 rose 1.1% but fell 1.1% for the week, weighed down by shares of European auto makers.

Japan's Nikkei Stock Average fell 0.8% Friday and 1.5% for the week, while the Shanghai Composite Index dropped 4.4%, its worst week since February.
