Superinvestors (SEC 13F-HR, Q2 2026) (DIOD)

1 of 80 tracked investors hold DIOD. Each row is the investor's latest 13F; change is vs their prior-quarter share count.

Insider sales (SEC Form 4, open-market, last ~7 months) (DIOD)

0 of 13 under a Rule 10b5-1 trading plan (scheduled in advance). Unplanned sales were timed by the insider.

% 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.
