It seems a mechanism designed to abuse.
Buy lots of share X, price of share X goes up, short lots of share X then straight away sell your large amount of share X, price goes down, so you make money on the rise and the fall.
The money comes from somewhere, and usually it means some real person just lost their savings.

They regularly ask us about our attitude to our pension investments, asking us if we're interested in a high-risk, or low-risk model, and such in-between.
It's definitely a conversation worth having with your pension provider.
