Methodology: Bloomberg ranked CEOs of technology companies based on the improvement of each company's stock performance from the week before its CEO's appointment was announced until October 11, 2013. Companies were drawn from a list of the top 250 U.S. technology companies by market capitalization. The list included companies in the e-commerce, Internet media and Internet-based services industries, and excluded companies in the distribution, information services and payment and data processor industries. Excluded were CEOs who were founders of their companies or had tenure of less than one year or more than 10 years as of October 11, 2013.

To create this ranking, the total returns of the stocks were calculated from one week before the CEO's appointment was announced (because rumors may have been circulating) until October 11, 2013, and for the two years prior to that period. These returns were compared to the performance of the S&P 500 for the same periods and the difference in percentage points was calculated. All returns are cumulative. Only companies that underperformed the S&P 500 prior to the CEO announcement period and outperformed since that time appear on the list.
