[Screen Shot 2016 05 03 at 7.23.46 AM copy]Investing.com Major global markets and US stock futures were weaker on Tuesday after some ugly news out of China. Near 7:10 a.m. ET, Dow futures were down 122 points, S&P 50 futures were down 14 points, and Nasdaq futures were down 33 points — all by less than 1%. On Monday, stocks rose steadily into the close with the Dow finishing up 117 points. To catch you up on the big markets news so far: * Chinese manufacturing data showed the sector slowed in April. UK manufacturing also contracted, as the PMI fell below 50 for the first time in three years. * The Reserve Bank of Australia cut its cash rate by 25 basis points to a record low of 1.75%.

And so, "China concerns" is an explanation we're starting to see again for the sell-off on Tuesday. The Dax was also down 1.7%, while the Nikkei fell 3.1%. The US economic-data calendar is light.
