Dealmaking in the chip sector lifted the Nasdaq to a new intraday high on Monday but losses in the telecom sector after the collapse of merger talks between Sprint and T-Mobile weighed on the S&P and the Dow. Shares of Qualcomm rose as much as 5.7 percent before paring some gains and were the second biggest boost to the tech-heavy index after Broadcom offered to buy the smartphone chip supplier in what could be the biggest merger in the tech sector. Broadcom was off 0.6 percent.
"The fact that the deal is on the table is huge," said Paul Nolte, portfolio manager at Kingsview Asset Management in Chicago. "We have not seen much in the way of dealmaking this year. So this might jumpstart some of the dealmaking ahead of the tax policy changes."
