Stock Ticker

Stock ticker symbol — the short exchange identifier for a listed security (AAPL, MSFT, BRK-B). 1-7 uppercase letters, optionally with a class-share suffix (BRK-B, BF.B). No check digit, and the shape confirms every short uppercase token (a US state code, a currency, an arbitrary code all clear it), so the published listed-symbol set is the substance (Precision Principle). US-listed for now (SEC company_tickers.json); other venues compose additively behind this same type.
