"One of the company’s longtime clients, David Kotok of Sarasota’s Cumberland Advisors, says the research his firm purchases from Davis helps his investment decision-making. “We manage hundreds of millions; Ned Davis is one of the research services we use. They’re high-class, first rate,” Kotok says. 'They offer guidance that enables investors to stay in trends longer than human nature would allow. It helps me extend positions to greater maturity, to cut losses and take smaller losses.'"
