"Google rallied $89.87, or 20 percent, to $539.41, the most since its August 2004 initial public offering and the biggest gain in the S&P 500. The owner of the most popular Internet search engine said sales rose 46 percent as more users clicked on text advertisements. Overseas sales, accounting for 51 percent of revenue, increased 55 percent.
Based on the size of Google's price changes in the past, today's gain represents a 1-in-300,000 days' occurrence, Bloomberg data show. The stock previously never posted a gain that would qualify as a 1-in-100 days' or rarer occurrence.
Options on Google accounted for the four biggest gains among all U.S. stock options tracked by Bloomberg. Contracts that gave the right to buy Google shares for $520 through today's close surged 117-fold."-Bloomberg
