RE:RE:RE:RE:RE:RE:Someone aware of somethingYou are right that shares are fungible between exchanges, Twiggy. But when you buy/sell shares of a company, you do so under a particular ticker on a particular exchange. And if you want your broker to fill the order via another exchange, they are going to hit you with currency conversion and international trading fees. In other words, for most holders, you are stuck trading in the exchange you bought in, unless you want to pay a bunch more to your broker or an intermediary steps in and scalps a few bucks to do the transaction across mutiple exchanges for you. And from what I can see, almost no one currently owns the ticker GSP.L. Maybe Calvin Redlick and a few other European holders switched their shares to GSP.L when it went live. But I would expect those folks are sitting pat currently. And so it has only traded about 300 shares a day on average.
