Toledo - Cashflow from the world's 3rd largest Nickel Resource

PV: thanks, I wasn't aware of 'mini-CFDs'.
The margin requirement and spread would both be pretty savage - the latter much worse than the typical SP spread.
In which case today's fall would just about have covered the spread...

fizz: they'd be talking about 'traded options' which are restricted to about 70 of the largest caps.

There is (or was until recently) such a thing as a 'traditional option', which lasts 3 months and can't be traded - you can call, put or double.
The only way to do this with TMC would be for a broker to find someone to 'write' it for you.
The cost would probably be about 40p/sh for the right to sell at (say) 130p.
Then the brokerage is for the full number of shares.
This can make a lot of money - for the writer.
