Data issued Monday revealed that China decelerated to its slowest pace since the global financial crisis last quarter, raising questions whether the world’s second-largest economy can meet its annual gross domestic product target of about 7 percent.

China’s economy expanded by 6.9 percent in the July-September quarter, down from 7 percent in the prior quarter. But the figure still beat expectations slightly as economists had forecast GDP would grow 6.8 percent in July-September period from a year earlier, according to analysts polled by Thomson Reuters.

The continued steadiness of China’s official GDP figures will further raise concerns over the data’s credibility.

“These figures need to be taken with a grain of salt as official GDP growth appears to have become a poor gauge of the performance of China’s economy,” Julian Evans-Pritchard, China economist at Capital Economics, said in a research note Monday. “We do think the official figures are currently overstating growth by a wide margin; we nonetheless have reason to think that actual growth was indeed broadly stable last quarter.”

Shares of Morgan Stanley (NYSE:MS) sank 5 percent Monday after the sixth-biggest U.S. bank by assets posted third-quarter earnings and revenue that missed Wall Street forecasts, driven by a 17 percent decline in trading revenue. The decline in the bank’s trading unite contributed to a 42 percent drop in profit last quarter.

Notable companies reporting quarterly results after the closing bell include technology company International Business Machines Corp. (NYSE:IBM), which beat estimates in the prior quarter, while revenue fell short of expectations. The company continues to shed unprofitable businesses, such as its chip segment, to focus on cloud-computing initiatives.
