I can't remember all the reasons the Amex discusssion dropped down in priority but certainly 2007-2008 had some thing to do with it. It's costly and time consuming to be a reporting issuer in 2 jurisdictions and I doubt it will become a high prioority anytime soon for ECU. It will not solve the naked shorting problem or computer players and may even help them. Of the other side it does make it easier for US citizens to buy stock but to date this has been largely a non-factor in the bullmarket in PM's but maybe it's changing. I hope so because that would signal the next phase has started for this precious metals bullmarket. To me though most retail investors in the US have barely dipped their toe into the equity markets in general in the US since 2008 and small to medium sized institutions can get good fills through brokers on Canadian exchanges now.
