What does “/” and “^” mean in ticker symbols? How to translate these symbols into yahoo?
There isn't a single universal way to reference a stock, there are 4 major identifiers with many different flavours of exchange ticker (see xkcd:Standards) I believe CUSIPs and ISINs represent a specific security rather than a specific listed instrument. This means you can have two listed instruments with one ISIN but different SEDOLs because they are listed in different places. The difference is subtle but causes problems with settlement Specifically on your question (sorry I got sidetracked) take a look at  CQS Symbol convention to see what everything means
