Google Inc (GOOGL.O) announced a surprise overhaul of its operating structure on Monday, creating a holding company called Alphabet to pool its many subsidiaries and separate the core web advertising business from newer ventures like driverless cars. “It suggests that in all likelihood, Google is not going to slow the pace of their experimental processes like self-driving cars,” said Michael Yoshikami, head of Destination Wealth Management, which has $1.5 billion under management. The surprise news sent shares of Google up as much as 7 percent to $708 in after hours trading.
