Just noticed this.... I have my primary Schwab account and another "separate" account for our son. Noticed this bug/feature... The "total shares held" as reported are including the separate account, but not displaying the transaction history from that separate account.
ie - 200 shares as shown from my account - and NONE shown from the other account,
yet those extra 25 shares are reported in the total shares held ....
SO - "separate" accounts are a coin toss in reporting info -
