There is no salary here to measure against. Optex Systems Holdings Inc's chief executive is paid a token, so dividing a holding by it says nothing.
Which is why this company is in neither direction of the chief executive filter on the transactions page. A stake that cannot be expressed as a multiple is not the same thing as a small one.
No percentages here. These insiders hold more than one class of share between them, and the share count on file covers one of them rather than all. Dividing the two would compare different things.
