Chipmaker TriQuint ( TQNT) raised first-quarter guidance for investors after the close Monday, saying revenue will be stronger than forecast. In the March quarter, the company said revenue will range from $85 million to $87 million, compared with its earlier forecast of $81 million to $83 million. Still, the forecast for the company's expected loss in the quarter remains 1 cent to 2 cents per share. Analysts polled by Thomson First Call were expecting a 2-cent loss on sales of $82.63 million. In a statement, the company said it raised its revenue forecast because "shipments and bookings have been very strong so far in this quarter and end-market demand remains robust in most of our markets". Triquint closed Monday's regular session down 27 cents, or 3%, to $8.12 a share; after hours, the stock was recently up 7 cents, or 0.9%, to $8.19. The firm will give more detailed guidance in a forthcoming conference call.
