About Preferred Stock AI
Preferred Stock AI (preferredstock.ai) is a research tool for preferred stocks, preferred shares, and baby bonds, built for income investors. We pull together the numbers that actually matter for these securities — current yield, dividend, liquidation preference (par), discount or premium to par, call date, maturity, ex-dividend dates, and cumulative/convertible status — and cross-check the structural terms against the original SEC filings.
What makes it different
- Built specifically for preferreds and baby bonds — not an afterthought bolted onto a common-stock site.
- SEC-verified terms. Par, coupon, call, and maturity dates are checked against the prospectus on SEC EDGAR, with a link on every security page.
- Plain-English mode. Every figure can be explained in plain language for newer investors, or shown data-only for pros.
- Free to use. No account or password required to research; advertising and affiliate partnerships keep it free.
Where the data comes from
Market and dividend data are powered by Tiingo. Company reference data, prospectuses, and filings are sourced from SEC EDGAR. Quote data is delayed at least 20 minutes.
Who runs it
The Site is operated by Madison Labs.
