Do quarter-over-quarter 13F allocation changes constitute explicit trading signals?

No. Quarter-over-quarter changes reflect a combination of active trading and market price movement. A weight increase can result from price appreciation alone, without the manager adding shares. Share-count delta is the cleaner indicator of explicit trading activity.
