Friday's Tech Winners & Losers

Shares of California Micro Devices(CAMD Quote) were among technology's losers Friday, dropping 26% after the maker of analog semiconductor products cut its first-quarter earnings and revenue guidance.

For the period ending June 30, the company now sees a loss of 12 cents to 13 cents a share. Including its Arques Technology product line, but excluding acquisition costs and stock-based compensation costs, the company expects earnings of 2 cents to 3 cents a share. California Micro projects revenue of $15 million to $16 million, down $2 million from its earlier forecast. Analysts polled by Thomson First Call had forecast earnings of 4 cents a share and revenue of $17.7 million.

"With the exception of our packaged EMI filter ASIPs and low capacitance ESD devices, we have seen a broad based decline in demand for our products in the last month," the company said. "We believe this is due in part to softer market demand and in part to the competitive inroads by ceramic filters and packaged ASIPs at certain mobile handset customers." Shares were trading down $1.53 to $4.33.

Oracle(ORCL Quote) rose 3% after the business-software company previewed better-than-expected fourth-quarter earnings. When the company reports earnings next week, it expects to post a profit of 24 cents a share, ahead of its previous guidance of 21 cents to 23 cents a share. Excluding certain items, Oracle sees earnings of 29 cents a share, up from its previous forecast of 26 cents to 28 cents a share, and above analysts' estimates of 27 cents a share. Pro forma revenue, meanwhile, increased 22% to $4.94 billion, better than the 10% to 14% increase that Oracle had forecast. Analysts project revenue of $4.55 billion. Oracle plans to release its full results on June 22. Shares were trading up 46 cents to $14.16.
