Dow futures move slightly higher as investors focus on US-China trade

U.S .. stock index futures were a little higher on Tuesday morning.

Around 06:20 ET, Dow futures indicated a positive opening of about 25 points. Futures at S&P and Nasdaq were both marginally higher.

Market players are still focused on China-U.S. trading news, amid some concerns about plans to sign a trade deal in the coming weeks. President Donald Trump said Friday that he had not agreed to scrap customs on Chinese goods. His comments followed news earlier last week, from the Chinese Ministry of Commerce where they said both sides had agreed to cancel existing tariffs in phases.

On Tuesday, President Trump will speak at the New York Economic Club where he could provide clues to the status of US-China trade talks.

Hong Kong instability is also on investors' radar. Hong Kong's main index, Hang Seng, rose fractionally on Tuesday. This, after dropping 2.5% on Monday amid further protests.

On the data front, the calendar is thin, with only the National Federation of Independent Business optimism survey at 6am ET.

CBS, Nissan, Datadog and DR Horton report on Tuesday.
