SAN FRANCISCO (MarketWatch) — Tech stocks ended up closing the week out with mixed results Friday, with mild gains from Amazon.com Inc. and Yahoo Inc. among the few sector bellwethers to rise and a huge first-day approval for newly public cloud-software company Castlight Health Inc.
Amazon /zigman2/quotes/210331248/composite AMZN +2.49% rose $2.23 to close at $376.22 a share a day after the online retailer said it would raise the annual price of its Prime delivery service to $99 from $79. Industry analysts said they didn’t expect Amazon to lose many customers as a result of the price increase.
