% of holdings sold = shares sold ÷ (shares sold + all holdings the insider reported on that Form 4, direct and through trusts).

Insider type follows Cohen, Malloy & Pomorski (Journal of Finance, 2012). An insider who traded the stock in the same calendar month in each of the past three years is a routine trader; one who traded in each of those years without such a pattern is an opportunistic trader. In their study, trades by opportunistic insiders predicted future returns and trades by routine insiders did not. Counts open-market purchases and sales only (SEC Form 4 codes P and S) by that insider in that company. Not investment advice.
