Is this Thomas M Siebel’s net worth? No. A Form 4 reports the shares an insider owns in one company after each transaction, directly or through trusts and entities. It says nothing about cash, other investments, property or debt, options not yet exercised are not counted here, and a holding reported some time ago may have changed without a new filing. The value is shares times the last stored close, not a price anyone received. Sources: the filings listed below, each linked to EDGAR. Compare with the biggest insider stakes.

What OQRO is
OQRO reads the public record for US-listed companies — insider trades filed with the SEC, stock trades disclosed by members of Congress, fund holdings from 13F filings, and federal contract awards — and puts each one in plain words next to the filing it came from. It describes what was disclosed. It does not give investment advice or tell you what to buy.
