HanWool Materials Science, Inc.: what insiders have been doing
HanWool Materials Science, Inc., classified in the Chemicals sector, is a listed company. Its insiders report their share dealings to DART (FSS). The last twelve months, up to 2 November 2026, brought 16 filings signed by 4 insiders.
Only sales appear on the open market, 11 sales in all, filed by 2 insiders. The totals do not cover 11 filings with an undisclosed amount.
Compared with its exchange (2,655 companies, median 7 filings), a count of 16 filings is above the norm. The full history, which starts in 2021, counts 13 purchases against 25 sales.
The median gap between a trade and its publication by DART (FSS) is 19 days. That lag is the time during which only the insider knows about the trade. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify.
