U.S. stocks halted a two-day advance as a rally in crude faltered and Treasuries erased losses, providing a fresh signal that China-fueled turmoil on financial markets has yet to fully subside. The Standard & Poor’s 500 Index extended declines after European markets closed modestly higher. The yield on the 10-year Treasury note fell to 2.09 percent, while gold erased losses to trade above $1,090 an ounce. Oil was little changed at $30.50 a barrel. Emerging-market rose after closing at the lowest level in six years, while Asian stocks rebounded from a three-year low on Chinese trade data. The S&P 500 fell 0.5 percent at 12:04 p.m. in New York, with losses extending after Europe’s markets closed at 11:30 a.m. The gauge opened higher by as much as 0.6 percent. It’s now down more than 5.5 percent this year after slipping 0.7 percent in 2015. Source: Bloomberg
