Early indications suggest that Wall Street stocks may open Monday’s session notably lower, as global equities plunged following China’s opening horror show. After a private survey showed manufacturing activity in China contracted at a faster pace, Chinese stocks sold off close to 7 percent, triggering circuit breaker trading halt. The rest of Asia also wilted, and despite the release of fairly strong domestic manufacturing activity data, European stocks are deep in the red. Added to China fears, geopolitical tensions surrounding the standoff between Iran and Saudi Arabia exacerbated as the latter severed diplomatic ties with the former, sending oil higher. Two separate U.S. manufacturing readings and M&A news, if any, may also impact sentiment.
