A Wall Street rally sparked by the new US-China trade deal lifted US stocks to their third straight record closes on Monday.

Investors were also cheered by upbeat economic data out of China.

The benchmark Dow Jones Industrial Average closed up 0.4 percent at 28,235.89 while the broader S&P 500 added 0.7 percent to close at 3,191.45.

The tech-heavy Nasdaq rose the furthest, closing up 0.9 percent at 8,814.23.

All three indexes were at record levels, with the S&P and Nasdaq settling at all-time highs for the third day in a row.

US and Chinese officials on Friday announced a partial trade deal, with Washington canceling and reducing some tariffs in exchange for Chinese pledges to increase purchases of US exports and adopt trade reforms.

“I think the market is rallying simply because the worst case scenario of US-China trade plumetting is off the table.”

The timeline for getting the globally grounded planes back in the air following two deadly crashes is increasingly uncertain.
