Companies are ranked in order of their stock market value as of June 30. The previous rankings were compiled at the end of March.

Shares in Google were at $291.25 on Nasdaq as of 5.15pm BST on Monday. When the company held its IPO last August, its shares were priced at $85 per share. During the first day of trading, it share price closed at just over $100 per share. In May, Google shattered Wall Street expectations with a near six-fold surge in quarterly profit. For the first quarter ending March 31, the company reported net income of $369.2m, up from $63.9m in the year-ago quarter. Sales almost doubled from $651m to $1.25bn.

General Electric retains first place in the FT survey, followed by oil giant ExxonMobil, software heavyweight Microsoft Corp, and the world’s biggest financial services firm, Citigroup. Oil group Royal Dutch/Shell leap-frogged BP into fifth.

Meanwhile, several well-known names have dropped out of the rankings. For some, such as Telecom Italia Mobile, this reflects mergers, but other companies, including advertising group WPP and Sun Microsystems Inc, have simply seen their shares fall out of favor.
