🏷️ CUSIP Security Types

The 8th character in a CUSIP indicates security type: '1' for stocks, '2' for bonds, '3' for warrants, and '4' for rights. For example, Apple's common stock CUSIP 037833100 ends with '0' (stocks can also end in 0), while Apple bonds might end with '2'. Understanding these codes helps quickly identify security types when analyzing portfolios or conducting research.
