Shares of

Ixys

(SYXI)

were among technology's losers Tuesday, falling 22% after the company cut its first-quarter sales outlook.

The chipmaker now expects sales of roughly $63 million, down 9% from the $69 million the company reported during the fourth quarter. Previously, the company said that it would post flat sequential sales. "Our streak of 13 consecutive quarters of increasing revenues has ended," the company said. "Given our exceptional growth in revenues over the past three years, it is not all that surprising that a correction occurred." The company blamed the sequential shortfall on sales that weakened in Europe and weakness in plasma display panel sales. Shares were recently trading down $3.25 to $11.75.

(MOTV)

fell 27% after the software maker cut its second-quarter guidance. The company now expects pro forma earnings of breakeven to 2 cents a share on core sales -- which excludes acquisitions -- of $21 million to $22 million. Total sales are expected to be between $22 million and $23 million. Previously, the company expected earnings of 6 cents to 7 cents a share on core sales of $25.3 million to $25.8 million. The company previously forecast total sales of $26.3 million to $26.8 million. Analysts polled by Thomson First Call had been expecting earnings of 7 cents a share on sales of $26.6 million. "We had a significant transaction push out past the end of the quarter and our consulting services revenue fell short of our estimates," the company said. Shares were trading down $2.89 to $7.97.
