Nasdaq turns flat as tech stocks give up early advance

The Dow Jones Industrial Average was up 36 points, or 0.2%, to 21,817 and was on track for a 0.6% weekly gain, after two weeks of declines.

The S&P 500 advanced by 4 points, or 0.2%, to 2,442, with 10 of the 11 main sectors trading higher. The benchmark index looked set to finish the week 0.7% higher.

The Nasdaq Composite Index reversed gains to trade 7 points, or 0.1%, lower at 6,265 but was on track to finish the week 0.8% higher. This would be the first weekly gain in five weeks.

"The initial jump to Yellen's speech was because traders were anticipating something dovish from Yellen, but she did not talk about policy," said Michael Antonelli, equity sales trader at Robert W. Baird & Co.

Antonelli warned not to read too much into any market moves amid low August volumes.

"Most people are away, so moves tend to be amplified for no good reason. Technical analysts may point to the 50-day moving average of the S&P 500, which the index keeps failing to break through," Antonelli said.

Selling on the S&P 500 appears to have began shortly after the index rose above 2,450, which is the 50-day moving average.

Jackson Hole: European Central Bank President Mario Draghi will also be closely followed for hints as to when and how the bank will begin to unwind its monetary easing.

"The ECB President has made a habit of going off script at Jackson Hole in the past, and whilst a report from Reuters last week stated insiders believed no major policy announcements were to be made, many are hoping he may let slip an implicit hint at the start date of the ECB's long-awaited [quantitative easing] taper," said Croft.

Draghi is scheduled to speak at 3 p.m. Eastern.
