The newest entry dates from 25 November 2011: a transaction, in Southwall Technologies Inc /DE/. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. The legal deadline for a Form 4 is two business days after the transaction. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
