Intel Corp., the world's biggest chip maker, is among companies projecting sales will keep climbing as businesses invest in new equipment and the global recovery gathers momentum.
Warmer weather last month caused utility use to drop by the most in four years, limiting the overall gain in national industrial production to 0.1 percent, less than anticipated, the Fed's report showed.
