Google shares hit a three-year low on Monday after Barclays Capital analyst Douglas Anmuth lowered his earnings estimates for the company. Anmuth said that he saw indications that the search business is deteriorating. Google shares closed at $318.78, down 3.7% for the day and down more than 50% from a year ago. Google’s current market capitalization is $100.2 billion, the lowest in more than three years.

Things could be worse though for Google: Shares of General Motors (GM) were trading at 60-year lows on Monday, following a Deutsche Bank downgrade and a new stock target price of $0 (yes, that is “zero”). GM has a market capitalization of $1.9 billion, which is less than two days of revenue reported by Exxon Mobil for Q3 (the company reported an average daily revenue of $1.5 billion for all 92 days of the quarter).
