Investors are breathlessly anticipating that Google will make an initial public stock offering (IPO).

Wall Street rumours suggest the company will announce such an offering today, placing its stock on sale later in the year.

AP says: "Notoriously optimistic entrepreneurs in the epicenter of the world's tech industry say Google's IPO could become a potent psychological symbol of a broad rebound."

Investors anticipate the offering could yield Google as much as $2 billion.
