About us: who we are and where our data comes from

Obligacyjny Inwestor is a Polish website about bonds, run by Wojciech Pabjaniak, who has worked in IT for more than ten years and has been investing in the capital markets for five. The site brings together data on corporate bonds listed on Catalyst, the Warsaw Stock Exchange’s bond market. Otherwise, this data is scattered across company announcements, periodic reports, issue documents and exchange pages.

Where the figures come from

We use primary sources: companies’ current reports (filed through the ESPI and EBI systems), periodic financial reports, issue documents (terms and conditions, final terms) and data from GPW Catalyst. Yields to maturity come from DM BDM, a Polish brokerage house. Not every source carries the same weight: an audited annual report ranks above a current report, a current report above a press article, and a press article above promotional material from the issuer. When two sources disagree, the higher-ranking one takes precedence and we note the discrepancy.

How every figure is checked

• Each figure has a named source and a date.
• When a value cannot be confirmed, the page shows “no data” instead of an estimate.
• When sources disagree, the page says so.
• Our own tools, including AI models, collect and organise the data; figures are checked against the source before publication, and a daily automated check compares the figures published on the site with our records.

What this site does not do

The site describes bonds and issuers; it does not rate them or give investment advice, and its author is not a licensed investment adviser. Investing in bonds carries the risk of losing some or all of the capital invested, for example if the issuer defaults.
