Five Things Everyone Will Be Talking About Today

China data disappoints while European manufacturing impresses, and expectations for a December rate hike are a coin flip. Here are some of the things people in markets are talking about this morning.

China's official purchasing managers index was unchanged at 49.8 in October according to the National Bureau of Statistics on Sunday. The Shanghai Composite Index closed 1.7 percent lower following the release. Stocks were also put under pressure after authorities detained a top-performing hedge-fund manager in widening probes into market manipulation and insider trading. More China data is expected later this week, including foreign reserves and trade data. The International Monetary Fund may also announce a decision on whether to include the Chinese yuan in its basket of reserve currencies.
