For context, the typical company on the same exchange (median of 736 companies) published 5 filings over the same period, against 18 filings here. Over the whole record (from 2017), the tally stands at 39 purchases and 15 sales.

The shorter that gap, the sooner other investors can see what insiders have done. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives.
