Stocks plummet to finish their worst week in two years

U.S. stocks slumped Friday, and the market suffered its worst week in two years, as fears of inflation and disappointing quarterly results from technology and energy giants — including Apple, Alphabet and Chevron — spooked investors. The Dow Jones industrial average dropped by more than 650 points.

Bond yields rose and contributed to the stock market swoon after the government reported that wages grew last month at the fastest pace in eight years. The Dow had its worst decline since June 2016, while the broader Standard & Poor’s 500 index had its biggest one-day percentage drop since September 2016.

“We’ve enjoyed low interest rates for so long, we’re having to deal with a little bit higher rates now, so the market is trying to figure out what that could mean for inflation,” said Darrell Cronk, head of the Wells Fargo Investment Institute.

The increase in bond yields hurts stocks in two ways: It makes it more expensive for companies to borrow money, and it also makes bonds more appealing to investors than riskier assets such as stocks.

Several major companies, including Exxon Mobil, Chevron and Google’s parent company, Alphabet, sank after reporting weak earnings. Apple fell on concerns about iPhone sales.

The sharp decline in stocks this week short-circuited a robust start to the year that was spurred by strong global economic growth, solid company earnings and lingering enthusiasm for the GOP tax overhaul. Even with the pullback, the major indexes are still up more than 3 percent this year.

The downturn also follows a long period of unprecedented calm in the market. Stocks haven’t had a pullback of 10 percent or more in two years, and hit their latest record highs just one week ago.

The S&P 500 fell 2.1 percent to 2,762.13. The index has lost 3.9

percent since hitting a record high a week ago.

The Dow lost 2.5 percent to 25,520.96. The Nasdaq slid 2 percent to 7,240.95. The Russell 2000 index of smaller-company stocks gave up 2.1 percent to 1,547.27.

While interest rates are low by historical standards, they’ve been rising more swiftly, and that’s what has markets on edge.

The increase has been driven by the prospect of stronger economic growth, and higher inflation, in the U.S. and abroad.

Bond prices declined again Friday, pushing yields higher. The yield on the 10-year Treasury note, a benchmark for interest rates on many kinds of loans, including mortgages, climbed to 2.84 percent, the highest level in roughly four years. The rate was at 2.41 percent four weeks ago and 2.66 percent on Monday.

“Once we started going north of 2.5 percent, and you put that together with an overbought market, it had the ingredients of a sell-off, especially since January was so strong,” said Jeff Zipper, regional investment strategist at U.S. Bank Private Wealth Management.

The S&P 500, which many index funds track, soared 5.6 percent in January, its biggest monthly gain since March 2016.

One concern for investors is that the Federal Reserve will respond to higher inflation by raising its key interest rate more quickly than expected. The government’s latest job and wage data stoked those concerns Friday.

U.S. employers added a robust 200,000 jobs in January, slightly above market expectations for an 185,000 increase. Meanwhile wages rose sharply, suggesting employers are competing more fiercely for workers. The figures point to an economy on strong footing even in its ninth year of expansion, fueled by global economic growth and healthy consumer spending at home.

That’s good news for Main Street, but not for Wall Street. Some economists were predicting Friday that the central bank will raise its benchmark rate four times this year, rather than the three times that most previously expected.

The market slide may have been overdue, particularly after the strong start for stocks this year where the S&P 500 had its best January in two decades. Some investors saw a potential buying opportunity.

Alphabet slumped 5.3 percent after the Mountain View company reported results that missed analysts’ forecasts.

Exxon Mobil dropped 5.1 percent and Chevron lost 5.6 percent after the oil companies’ quarterly results fell short of forecasts.

Apple declined 4.3 percent after the Cupertino company said it sold 77.3 million iPhones in the last quarter, below the 80 million analysts expected.

Meanwhile, Amazon rose 2.9 percent after its fourth-quarter profit increased by more than $1 billion.

Major stock indexes in Europe also declined Friday. Germany’s DAX slid 1.7 percent, France’s CAC 40 lost 1.6 percent and the FTSE 100 index of British shares gave up 0.6 percent.

In Asia, Japan’s Nikkei 225 fell 0.9 percent and South Korea’s Kospi slid 1.7 percent.
