Wall Street muted on doubts over progress in US-China trade deal

The S&P 500 and Dow indexes treaded water on Thursday as mixed headlines on US-China relations and a diplomatic row over the Hong Kong protests added to uncertainty over the timing of a "phase one" trade deal.

The US House of Representatives passed two bills to back protesters in Hong Kong and send a warning to China about human rights, a measure which angered Beijing.

But China has invited top US trade negotiators for a new round of face-to-face talks in Beijing, the Wall Street Journal reported on Thursday, citing unnamed sources, adding Beijing hopes the round of talks can take place before next Thursday's Thanksgiving holiday in the United States.

This was the day after stocks sold off on a report that a Phase 1 US-China trade deal was not likely to happen this year. As a result investors were sticking to the sidelines for fear of missing out if relations were to improve, but keeping in mind that Wall Street's indexes were still near record highs.

"They are basically saying we've pushed this as far as we can. Valuations appear stretched at 18.5 times forward earnings compared with the 20-year average forward P/E Of 16.5," he said.
