looking for us emerald energy and their validity?

Answer 1

Emerald Energy is based in the UK. They trade on the London Stock Exchange under the symbol EEN, and a London share price can be obtained on Yahoo Finance by entering the symbol EEN.L.

Shares of Emerald trade in the US under the ticker EMEYF. This is a Pink Sheets listing, which means it is not registered on a major exchange. You can buy shares, but be careful to set tight limit orders or you might end up paying way too much for the stock. Yahoo Finance also tracks the Pink Sheets shares, with very limited information, under the symbol EMEYF.PK.

Best of success.
