Hewlett-Packard ( HPQ ) is being removed from the Dow Jones Industrial Average, a sign of waning confidence in the company's turnaround efforts amid an historic slump in the personal-computer industry. The exit, announced Tuesday as part of the biggest reshuffling of the index since April 2004, delivers another blow to Chief Executive Officer Meg Whitman's quest to revive growth at the storied PC maker. Bank of America and Alcoa were also dropped. Replacing them will be Visa, Nike and Goldman Sachs Group. Hewlett-Packard's shares have declined for three straight years as consumers have abandoned PCs in favor of smartphones and tablets. Whitman last month scrapped her forecast for a return to revenue growth in 2014 as lackluster demand for hardware and services and aggressive price cuts amplify the impact of the downturn for computers.
