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.
