SAN FRANCISCO (MarketWatch)--Gains from Applied Materials Inc., Rackspace Hosting Inc. and Autodesk Inc.stood out among tech stocks Friday and helped the sector shake off early losses and close the week out on an upbeat note.

Applied Materials (AMAT) shares rose 8% to close at $20.21 after the semiconductor equipment maker reported a fiscal second-quarter profit led by sales from its silicon systems business.

Rackspace (RAX) surged by almost 18% to end the day at $36.12 a share after the cloud-services company said in a regulatory filing that it has hired Morgan Stanley to explore strategic options. The company said it has been "approached by multiple parties" in recent months about exploring everything "from partnership to acquisition."

Design-automation software company Autodesk (ADSK) saw its shares rise 8% to $51.67 after it reported a fiscal first-quarter profit of 32 cents a share on $593 million in sales. Wall Street analysts had forecast Autodesk to earn 21 cents a share on revenue of $568 million.
