Hi i have a question i need answering and im wondering if someone can help me..........Why does a company trade on 2 stock markets, like the irish and the london stock exchange? I bought shares from an irish company and they trade on the LSE and the ISE, there value on the irish is 0.04cent and on the london SE is £3.95. Why is there such a huge difference in value. Just learning about stocks and shares and trying something new. Your help would be appreciated....
