U.S. stocks fell, with equities posting their longest losing streak since January, after the biggest slump in eight years for Chinese shares amid concern over the nation’s economic growth.

The Standard & Poor’s 500 Index slid 0.6 percent to 2,067.85 at 4 p.m. in New York, after touching its average price during the past 200 days.

The S&P 500 has declined for four weeks out of five, and closed Monday 3 percent away from its May record. The benchmark measure is up 0.2 percent for the month. The bull market that already rivals anything since World War II in duration is showing signs of fatigue, as U.S. equities are being pushed along by the fewest stocks in more than 15 years.

More than 100 percent of this year’s increase in the S&P 500 is attributable to two sectors, health-care and retail. That’s the tightest clustering for an advancing year since at least 2000, data compiled by Bloomberg show.
