After the closing bell, Intel managed to top Wall Street estimates. Prior to the report, however, some analysts were skeptical. ABN Amro analyst Paul Leming cut his rating on the stock from "hold" to "reduce," saying he suspected Intel would "noticeably" miss forecasts. Intel shares were up 77 cents to $29.90.
Intel's results follow word from semiconductor equipment maker Novellus Systems that "business conditions remain exceptionally weak." ABM Amro analyst Nikolay Tishchenko lowered his predictions for the capital-equipment market for 2002, saying that in the absence of any seasonal uptick in PC and cellular-phone sales, growth could be limited to the single digits. He cut his ratings on Applied Materials, Cymer, KLA-Tencor, Lam Research and Novellus from "buy" to "add."
Nevertheless, investors speculated that the worst was over. Applied Materials was up $2.62 to $44.57, Cymer gained 70 cents to $23.11, KLA-Tencor was up $2.54 to $49.20 and Lam Research was up 95 cents to $25.72. Novellus was up $2.48 to $48.85.
