    3 real insider sales in 12 months. $270K in total, not counting planned sales.

−100 means everyone selling, +100 everyone buying. This is data, not advice.

How the Pulse works

Pulse runs from −100 (everyone selling) to +100 (everyone buying). Half comes from insiders: real buyers vs. real sellers in the last 90 days (Form 4). Half comes from funds: funds that bought vs. funds that sold last quarter (13F). 13F is a snapshot of long positions on the last day of the quarter, filed up to 45 days later. It does not show short positions or trades since then.

"Owns" is shares reported divided by shares outstanding.

Where this data comes from. Insider trades, fund holdings, activist stakes and company results come from public SEC EDGAR filings (Forms 4, 13F, 13D/13G, 10-Q and 8-K). Congress trades come from the STOCK Act reports members file with the House Clerk and the Senate. Daily closing prices come from post-no-preference/stocks on DoltHub, a community-run database shared under CC BY-SA 4.0; the prices we show stay under that license. They are each day's close, not live or official exchange prices.
