The difference between MMN and silver shares the way I see it; Futures don't trade on the extra variables like shares do, such as; shares on issue, investors depend on specific management performance and information that will influence the market, hits the market at a fairer rate as opposed to a speccy miner that may announce a share issue for 'work capital' out of the blue, also, it's a total different asset class and overall trading 'the real thing is easier, imo... Just the way I see it. In shares you have to pick the best out of a bad bunch (stockpickers market) with futures, no need to 'stockpick' ,the extra variables are non-present. my 2c.
