You know they are the same company? Or meant they're not? The same symbols can be used in different stock markets.
For a specific stock mark, tickers are unique and identify specific stocks or shares of a company. The same ticker code may, however, represent different companies on different exchanges. An example of this is the “DRI” ticker. On different exchanges it represents either the company “Drillisch AG” (Frankfurt Stock Exchange) or “Darden Restaurants Inc” (New York Stock Exchange). Sometimes additional codes are also added to a ticker that represent an exchange.
Nasdaq tickers have 4 letters (VIBE) so the E would be the 4th letter, not a 5th letter extension. Stocks traded on the New York Stock Exchange have symbols with up to three letters - like T (AT&T), DO (Diamond Offshore Drilling) and LUV (Southwest Airlines). Stocks traded on the NASDAQ usually have four-letter symbols - like MSFT (Microsoft).
