I have bought into this at 105 the other day, only 2.5% portfolio weight, trading small given volatility, should possibly be in for more.
CMC Markets is a Spreadbetting / CFD firm, basically a brokerage. In the UK this has some advantages, no stamp duty (0.5% acquisition price) and no Capital Gains Tax (CGT). The inland revenue allows spreadbetting to be tax-free as it is classed as gambling and most lose. I think its good value at the current price as the balance sheet is very strong, relative to the market cap and the regulatory risk which has caused the fall in the share price is mostly priced in.
You can buy this for zero comission via the broker on this link.
