1. Dow to advance at the open in a continuation of Monday's rally

Traders and financial professionals work on the floor of the New York Stock Exchange (NYSE) at the opening bell on August 19, 2019 in New York City.

U.S. stock futures were indicating at higher Tuesday open on Wall Street, a day after the Dow Jones Industrial Average made back nearly half of Friday's more than 600-point plunge. Stocks started the week higher as President Donald Trump said at the G-7 summit that China called and said it was ready for serious talks. China disputed whether a call took place. The Dow, S&P 500 and Nasdaq remained solidly in the red for August, tracking for their second monthly loss in an otherwise strong year of gains.

2. China weakens its currency again as US trade war continues

China's yuan weakened for the ninth straight session Tuesday, plumbing new 11½-year lows for the currency, as twists in the trade war between Beijing and Washington left investors skeptical of the chances of a near-term deal. The yuan has lost nearly 3% against the dollar since Aug. 1, when Trump threatened tariffs on more Chinese goods, starting next month. The Trump administration has accused China of currency manipulation, weakening the yuan in order to gain a trade advantage.
