1. China in the spotlight

Official data released Wednesday shows China's economy grew 6.7% in the third quarter.

That's exactly the same pace of growth as the previous two quarters and right in line with economists' forecasts.

But many experts have questioned the accuracy of China's headline growth figures.

"As always, the GDP figures will be met with some skepticism. For our part, we do think that China's economy is expanding slower than the official figures suggest," said Julian Evans-Pritchard of Capital Economics.

2. Earnings and economics

It's a big day for earnings and economic reports.

Morgan Stanley (MS), U.S. Bancorp (USB), Abbott Labs (ABT) and Halliburton (HAL) are posting quarterly updates ahead of the opening bell.

Shares in Intel (INTC, Tech30) are dropping by about 5% premarket as investors react to its latest earnings, which came out Tuesday afternoon.

On the economic front, the U.S. Census Bureau is releasing new September housing data at 12:30GMT.

The U.S. Energy Information Administration is reporting weekly crude oil inventory data at 14:30GMT

Shares in Mitsubishi Motors gained about 8% in Tokyo on Wednesday based on a report that the head of Nissan and Renault - Carlos Ghosn - will serve as chairman of the scandal-plagued firm.

If true, this wouldn't be a massive surprise given that Nissan (NSANF) announced in May it would spend $2.2 billion to take a 34% stake in Mitsubishi (MSBHY).

However, Mitsubishi refused to comment on the "speculative report".

Mitsubishi shocked its customers in April when it announced it had manipulated fuel economy tests affecting hundreds of thousands of vehicles.
