Delisted or non-tradable security. No daily market prices available for ADP. The chart below uses the IMPLIED price from each 13F filing (value ÷ shares), which gives one datapoint per quarter rather than a continuous price line. Buy/sell markers and the position-history table still reflect Berkshire's actual transactions.
