- Pre-planned sales of $23.7M (weaker signal)
50 is neutral. Buying by more insiders, top executives and bigger stakes raises it. Selling lowers it; pre-planned sales count less.

"Owns after" is the insider's holding right after the trade. Pre-planned (10b5-1) sales are set up months ahead, a weaker signal.
