What is the ticker symbol for Samsung?

Samsung Electronic's ticker is listed on the KOSPI as 005930. That's the Korea Stock Exchange (Koscom).
Not what you were thinking? Samsung is not traded in the U.S. on the NYSE or AMEX. That's why you don't see a "familiar" ticker in the answer. You want a piece of that company, you'll have to get a broker to buy in for you on the Korea Stock Exchange.
