What big investors reported

What changed since the prior report

Green means the manager reported a new or larger share amount. Red means a smaller amount or the stock was no longer listed. This compares two delayed reports; it does not show the exact trade.

PUT and CALL are contract labels, not common-share holdings. A 13F reports these option rows but does not establish whether the strategy is bullish, bearish, hedged, or part of a spread. It also does not reveal strike, expiry, premium, or the rest of the manager's book.
