“ First of all, how can you tell what date Berkshire stopped selling? “ Form 4s disclose the info.

Berkshire never owned 10% of Apple so they don't have to report like that. All we know is the average price BRK sold Apple stock for in the first quarter (approx. $173 / share) and in the second quarter (approx. $188.4 / share) - which indicates that they were selling when AAPL was stuck going sideways while big cap tech was rallying.

After that, AAPL shares caught up to the QQQ. Maybe that's a coincidence and the market was just super jazzed about some AI announcement.

AAPL was stuck going sideways while the QQQ rallied - there was a major daily seller at X% of the average daily volume throughout that period.
