Wall Street runs on two languages. One is formal: financial statements, analyst reports, SEC filings. The other is the fast shorthand traders use when they talk about what is actually happening in the market. A headline might say a company “delivered a strong print but the stock faded as investors digested cautious guidance.” That sounds complicated. It means the reported numbers were good, the stock went up at first, and then investors focused on weaker forward expectations and the price came back down.

A working reference for the vocabulary of financial markets — organized by domain, not alphabetically. Definitions are written for investors, analysts, financial journalists, and informed participants who need precision without the padding of a textbook. Market Structure Equity Ownership interest in a company, represented by shares of stock. Equity holders are residual claimants — they receive what remains after all creditors and obligations are satisfied. Common equity carries voting rights; preferred equity has priority in distributions but typically limited voting power.
