Tech stocks in the S&P 500 rose more than 1% to outperform the wider S&P index and the Dow Jones Industrial Average, both of which fell slightly.
Shares of Xoom, a provider of digital money transferring services soared more than 21% after an announcement that PayPal would acquire the San Francisco-based company in a deal worth about $890 million.
PayPal will pay about $25 a share for Xoom, which provides technology and services for transferring money and paying bills online via smart phones, tablets and computers. Xoom has about 1.3 million customers in 37 countries.
Post-deal, Xoom will operate as a separate entity from PayPal.
PayPal, which provides services for processing invoices and related functions, is a unit of the San Jose, Calif.-based e-commerce web site eBay (EBAY - Get Report) although it will be spun off later this month. Paypal said that the acquisition will close in the fourth quarter.
TheStreet has a hold rating on Xoom. It cited strong gains in revenue but had reservations about bottom line results and the company's overall performance compared to other software and service providers and the wider S&P 500.
"We rate XOOM a HOLD," TheStreet analysis said. "The primary factors that have impacted our rating are mixed - some indicating strength, some showing weaknesses, with little evidence to justify the expectation of either a positive or negative performance for this stock relative to most other stocks."
