All major US stock indexes posted all-time highs on Friday. The S&P 500 notched its sixth straight weekly gain, the index's longest streak in two years.

Here's a look at the major indexes as of the 4 p.m. close on Friday:

• The S&P 500 gained 0.77%, to 3,120.46.
• The Dow Jones Industrial Average climbed 0.8%, to 28,004.89.
• The Nasdaq Composite rose 0.73%, to 8,540.83.

The record highs came as White House Economic Adviser Larry Kudlow said late Thursday that the US and China are drawing closer to striking a trade deal, pumping investors with some optimism that a resolution could soon be reached.

Commerce Secretary Wilbur Ross said in an interview on the Fox Business Network on Friday that while progress has been made, some issues still remain.

"The president hasn't agreed to remove the tariffs," Ross said. "We'll see the details as they come through and they're gonna be good details or else the president won't go along with it."

• Applied Materials: 9%
