Subject: Re: Berkshire sells more BYD
The only price sold that gets disclosed is for the trading day that results in a change in the whole number percentage ownership of this specific share class - that is what triggers a required filing. So the price shown at the link I posted is for the final 1m shares. You can assume an average price over the period since the last filing. BYD has been pretty stable since October.
