US stocks struggle for direction, Nasdaq sets fresh record highs

Major US equity indices witnessed a subdued opening on Tuesday, with tech stocks outperforming the broader markets.

Tech-heavy Nasdaq Composite Index notched a second straight record high and was led by strong gains in the shared of Twitter, which jumped nearly 5.5% following an announcement that it would be included in the S&P 500 index.

Meanwhile, investors now seemed to have put returning trade tensions on the back burner, at least of the time being, with momentum buying, further supported by the positive macro news, sufficient enough to keep the ongoing bullish run intact. 

Adding to the recent slew of upbeat US economic data, the ISM non-manufacturing PMI for May jumped to 58.6 as compared to previous month's reading of 56.8 and provided a minor boost in the past hour or so. 

At the time of writing this report, the Dow Jones Industrial Average was flat-lined near 24,815, while the broader S&P 500 Index added around 3-points to 2,750. Meanwhile, Nasdaq climbed nearly 30-points and was seen building on its momentum beyond the 7,600 round figure mark.
