Also getting back to SDI as an investment case - to buy or sell, if we take the commentary at face value and the political uncertainty in South America was to blame for the accelerated decline in amalgam (and therefore the Aus direct exports also), and the equipment growth was to start gaining traction, as they suggest with the release of the new machine last quarter, then this drop may in fact only be a blip, and this drop could be the buying opportunity one would look for.
Unless you think the business case for SDI is broken, that it will no longer be a profitable business or profits will be low for perpetuity? SDI has been a small debt laden company (in 2011 it had 11mil debt and a pre tax profit of 1.3mil) which has battled the same Goliaths for the last however many years (admittedly the dynamic was different as an amalgam supplier), while progressively increasing the dividend 10 fold since 2011, and currently by my reckoning has the best balance sheet its ever had. Not a bad record by any measure. What part screams 'sell' to you?
