Stocks tumbled Thursday, with the Dow shedding 1.5% to 16945.80. The S&P 500 dropped 1.6% to 1965.99. Losses came amid ongoing concerns about global growth, the pace of Federal Reserve tightening and rising tensions between Western countries and Russia.
Recent action leaves the major indexes poised for weekly losses. The S&P 500 is off 2% this week. Investors remained concerned about economic growth overseas, especially in China and the eurozone.
Others remain optimistic about the outlook for stocks, arguing that steady economic growth in the U.S. means that the market can handle tighter Fed policy. Investors widely expect the central bank to raise rates sometime next year after winding down its bond-buying program in October.

Some investors say that Thursday's selloff and the resulting spike in market volatility simply mark a return to normal trading patterns after a sleepy summer for stocks.
"You should expect more volatility than we've had in the past couple years, and this week is a bit of a taste of that," said Russ Koesterich, chief investment strategist at BlackRock.
For Friday "it looks like the market has quieted down," Mr. Koesterich said. "A couple things are helping--the GDP print was in line, and also we didn't see a lot of follow-through selling overseas."
The dollar continued to strengthen against major rivals. The euro fell to $1.27 from $1.2751 late Thursday.
The yield on the benchmark 10-year Treasury note rose to 2.522%, according to FactSet. Yields move inversely with prices.
