There is no salary here to measure against. IMPACT BIOMEDICAL 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. This company's share count has moved by a factor of 9.4 over the window, from 11,503,955 to 107,821,231 shares. A split, a merger or a large issue changes what the company is, and a holding measured at one point in that run is not a fraction of it at another.
