I subscribed to the (free) daily trading email from Investors Chronicle, which is worth 10 minutes every day and in today's edition there's an interesting little bit on Plus500:
For the fifth time since February, the CFD provider has flagged record levels of platform trading activity, though customers' recent net gains, and uncertainty over Australian regulatory changes and continued market volatility, means internal earnings forecasts are in-line with market consensus. Such concerns keep us doubtful, too.
This seems to imply that they would make more money if their customers lost more often... just a misunderstanding on IC's part?
