Financial analyst responds to lowered guidance News & Analysis 8/11/2004 Post a comment Doug Freedman of American Technology Research says it's dangerous to assume the supply chain is inefficient. Some distributors are still overstocking on components, anticipating a demand they may not have. Better to turn the manufacturing spigot on-and-off against real demand, he feels. Suppliers like National Semiconductor could get whacked in the coming quarter by backups in the distribution chain. You have to maintain close relationships with your customers, Freedman insists, stop relying on
