Chinese PMI numbers released Wednesday were the best in seven months. The data, however, couldn't overcome the negative sentiment surrounding rising short-term rates.
The Chinese seven-day repo rate rose to around 5% on Thursday, its largest move since earlier this year. That rates have climbed so much signals to investors that the People's Bank of China fully intends on tightening monetary policy.
The PBOC's decision to tighten policy is in an effort to curb lending and cut off inflation. Inflation currently runs around 2.5%, but anything in the range of 3% is unwanted by the central bank.

Among world equity indices, China has been one of the weakest performers. Along with tighter policy measures, besides the strong PMI number Wednesday night, Chinese data has been a mixed bag.
Export growth was weak for September, and weak guidance from Caterpillar suggests industrial production won't be that great in the fourth quarter.
Equity investors have been looking for a correction lower in global markets all year, and China seems to be the first piece to crack.
Although other developed economies may not correct lower as drastically as China has, look for negative sentiment surrounding the region to weigh down a bullish thesis for the fourth quarter.
