Stocks slide as China growth worries fester

NEW YORK - Global equity markets traded slightly lower on Tuesday after their worst first-day performance in years as concerns about the global economy weighed on sentiment and pushed traders to seek the relative safety of the low-risk yen.
Crude prices also fell on concerns about the pace of growth in China, the world's second-largest oil consumer. News that Chinese rail freight volumes logged their biggest-ever annual decline in 2015 added to economic growth worries.
