Entering into Tuesday morning the S&P 500 opened lower at 4,493.
S&P 500 has drifted 0.35% lower early Wednesday, while the NASDAQ Composite is fairing worse.
The weakness comes following a string of poor reports from China, the UK and Germany that has led to a risk-off posture to start the week.
Each country's Purchasing Managers Index (PMI) for the Services sector showed a slowing rate from July. Germany's PMI for August dropped five points from July to 47.3. China's Caixin Services PMI fell from 54.1 to 51.8. The UK's Services PMI for August fell two points to 49.5.
The drop also comes on the back of announcements that Saudi Arabia and Russia are both extending their voluntary oil production cuts for another 3 months.
