S&P 500 Caps Worst Week Since ’12

New York — The Standard & Poor’s 500 index fell Friday, giving it the biggest weekly drop in two years as concern over Argentina and Portugal overshadowed data that signaled the Federal Reserve may have leeway to keep rates low.

JPMorgan Chase & Co. and Morgan Stanley slumped more than 2.1 percent as a committee ruled that Argentina’s default will trigger $1 billion of credit-default swaps. LinkedIn jumped 12 percent after projecting revenue that beat forecasts. Procter & Gamble increased 3 percent as profit topped estimates amid cost reductions.

The S&P 500 fell 0.3 percent to 1,925.15, bringing its weekly loss to 2.7 percent, the worst since June 2012. The Dow Jones industrial average declined 69.93 points, or 0.4 percent, to 16,493.37, after erasing its gains for the year on Thursday. About 7.3 billion shares changed hands on U.S. exchanges Friday, 27 percent above the three-month average.

U.S. stocks joined a global selloff Thursday, sending the S&P 500 to its first monthly decline since January, after companies such as ExxonMobil and Samsung Electronics reported results that disappointed investors, Argentina defaulted and Banco Espirito Santo was ordered to raise capital.

Banco Espirito Santo shares were suspended Friday by Portugal’s securities regulator after they dropped as much as 50 percent in Lisbon. Global financial markets were roiled last month after another holding company in the group missed payments on commercial paper.

Argentina’s failure to pay interest on its bonds is a credit event that will trigger settlement of $1 billion of default insurance, according to the International Swaps & Derivatives Association. Argentina is the first nation to trigger default swaps since Greece restructured its debt in 2012.

The S&P 500, which is still up 4.2 percent this year, has gone without a 10 percent correction since 2011. The benchmark index is down 3.2 percent from a record of 1,987.98 reached on July 24. It trades at 17.5 times the reported earnings of its companies, near the highest level since 2010.

Market volatility is rising after the S&P 500 ended its longest stretch of calm since 1995. The index has posted gains or losses of more than 1 percent three times in the past two weeks, compared with none during the 62 days through July 16, data compiled by Bloomberg show.

The Chicago Board Options Exchange volatility index, known as the VIX, rose 0.5 percent Friday to 17.03. The gauge surged 27 percent Thursday to the highest level since April 11. The volatility measure fell to the lowest since 2007 on July 3.

Stocks fluctuated earlier in the day as data showed employers in the United States added more than 200,000 jobs for a sixth straight month in July, the longest such period since 1997. The 209,000 advance fell short of the 230,000 increase forecast by economists.

The jobless rate climbed to 6.2 percent from 6.1 percent in June as more people entered the labor force. Wages and hours were unchanged from June.

Concern has grown that the improving economy may force the Fed to raise interest rates sooner than expected. Data earlier in the week showed U.S. gross domestic product expanded at a 4 percent annual pace in the second quarter, confirming the Fed’s view that a first-quarter contraction was transitory.

Manufacturing expanded in July at the fastest pace in more than three years, data Friday showed, signaling U.S. factories will help power the economy after a second-quarter rebound. The Thomson Reuters/University of Michigan’s final sentiment index for July fell to 81.8 from 82.5 in June.

The Fed last week cut its monthly bond buying to $25 billion in its sixth consecutive $10 billion reduction. The Fed’s Open Market Committee reiterated that it’s likely to reduce bond buying in “further measured steps” and to keep interest rates low for a “considerable time” after ending purchases. The central bank said slack in the labor market persists even though the economy is picking up.

Fed Bank of Dallas President Richard Fisher said he believes the timing has moved up for the first main interest rate increase from close to zero because of a strengthening economy and higher inflation.

“It would seem to me — and I have been arguing this — that the date of so-called liftoff has been moved forward,” Fisher said Friday in a CNBC interview. “I believe personally we have moved that forward significantly,” possibly as soon as “sometime early next year,” he said.

Chevron and Procter & Gamble are among six S&P 500 members that reported earnings Friday. Some 76 percent of the 379 companies that have released results this season have beaten analysts’ estimates for profit, while 65 percent have exceeded sales projections.

Seven out of the S&P 500’s 10 main industries dropped as phone and financial shares slumped the most, losing more than 0.8 percent. Consumer-staples companies rallied 0.8 percent.

P&G jumped 3 percent for the biggest advance in the Dow. Fourth-quarter profit beat analysts’ estimates, helped by cost reductions and an increase in razor prices. A.G. Lafley, who returned as P&G’s chief executive officer last year, has focused on cutting costs and regaining customers in areas such as detergents and beauty.

LinkedIn rallied 12 percent. The company gave a third-quarter sales forecast that topped estimates as the largest professional-networking website rolled out new products to reignite growth.

Expedia advanced 6.4 percent for the largest increase in the S&P 500. The provider of online travel services reported second-quarter profit of $1.03 per share, more than the average estimate of 76 cents in a Bloomberg survey. Revenue of $1.49 billion also beat projections.

GoPro slumped 15 percent. The camera maker, which sold about $1 billion last year in equipment to surfers, skiers and skydivers, reported a net loss of $19.8 million for the second quarter, almost four times bigger than its $5.1 million loss in the year-earlier period.
