Subject: Re: High Volume
According to both Charles Schwab and Yahoo Finance, the volume of Berkshire's B shares bought and sold yesterday exceeded 11 million, almost four times its average. Does anyone know, or have any ideas, as to why?

looking at the historical data there was a spike on June 16 and March 17. Not as pronounced as yesterdays, but still double/triple. Options??? or some othere regular 3 month occurrence.
