rose 3% after the semiconductor-equipment company lifted its fourth-quarter revenue guidance. For the period ending Sept. 30, the company now sees revenue of $151.9 million to $158.1 million. Previously, the company said it would post revenue of $135 million to $145 million. Analysts project revenue of $140.9 million.

Shares of

Palm

(PALM)

slumped 10% after the maker of smart phones cut its first-quarter revenue forecast. The company now sees revenue of $354 million to $356 million, down from an earlier forecast of $380 million to $385 million. The company continues to see adjusted earnings of 18 cents to 19 cents a share. Analysts project earnings of 19 cents a share on revenue of $382.9 million.

Palm blamed the revenue shortfall on lower-than-expected Treo smartphone volumes in carrier retail channels.

Shares were trading down $1.58 to $13.95.

platforms.

"While we anticipated a decline in future Intel-based chipset business following the announcement of the acquisition with AMD, the decrease occurred much sooner than we expected," ATI said. ATI was also hurt by lower-than-expected handheld revenue, which was caused by a supply chain adjustment by one of its major customers. Shares of ATI were recently trading down 9 cents to $21.31.
