Google Finance raises some questions about the market capitalization of Google between its Class A (GOOGL) and Class C (GOOG) shares.
https://www.google.com/finance?q=NASDAQ:GOOGL
Price: 546.69
Shares: 673.29M
Market Cap: 368.08B
https://www.google.com/finance?q=NASDAQ:GOOG
Price: 540.95
Shares: 697.33M
Market Cap: 377.22B
Market capitalization equals shares outstanding multiplied by price. This might suggest that Google's market capitalization is 745.3B, but it didn't double from the split because the share prices were halved. My guess is that the calculation for shares outstanding has not been updated.
Also interesting is the difference between the number of shares. Did Google distribute an additional 24 million shares of GOOG after the split? I suppose that was the point of the split in the first place, to put non-voting stock into circulation. That's 1.3B. That could certainly contribute to the falling stock price.
