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.
