Amendments, corporate actions, and changes in reporting scope can also move these rows. Value change compares period-end reported values; for continuing rows it includes market price movement.
Newly reported by Fisher Asset Management, LLC — Ken Fisher, GAMCO INVESTORS, INC. ET AL, MAVERICK CAPITAL LTD.
