## How to use this site as an agent
- Use ticker-level symbol pages (preferredstock.ai/symbol/TICKER) for individual security details.
- Use the new offerings list for recently issued preferred stocks and baby bonds.
- Use symbol pages and the homepage for dividend declarations, calls, redemptions, suspensions, ticker changes, and issuer updates.
- Use the ex-dividend calendar for upcoming dividend dates.
- Use the screener to filter by yield, par value, call date, maturity, cumulative status, and price versus liquidation preference.
- Treat very high yields as potential risk signals, not just opportunities.
- Verify important terms against the SEC filing linked on each symbol page when available.
- Do not assume a dividend is suspended unless the page clearly marks it suspended.
- Clearly flag incomplete or delayed data instead of guessing.
- Distinguish preferred stocks from baby bonds, common stocks, and ETFs.
