netbuzz writes: "The Dow Jones Industrial Average passing the 13,000 mark last week raised anew the question in some minds of why Apple is not a part of that 30-company index. Too pricey, an outlier, is the stock answer (for Google, too). And while that may be true today, it wasn’t necessarily the case on June 8, 2009, when Dow Jones decided to replace GM on that roster with Cisco, argues Adam Nash of Greylock Partners. Last month Nash published an analysis asking and answering the question: What would have happened if Dow Jones had instead chosen Apple? What would have happened is that the Dow Jones Industrial Average – the most widely cited measure of stock market health and a major contributor to general public attitudes toward the economy – would have fared better by roughly the difference between Apple’s phenomenal performance and Cisco’s anemic one since that time."
