Only 2 discretionary filings — too few to score

Discretionary filings only. 10b5-1 plan trades, tax withholding and option exercises are excluded, and each column is one row per filing rather than per execution lot.

Sell Track Record

Filings1

No scored decision-sell filings

Decision sells only — a first sale after buying the stock, or a sale by a fund or 10% owner. Ordinary sales by officers and directors show no relationship to what the stock does next, so they are counted but not scored.
