At first glance it is a story that people have loved for centuries.

David versus Goliath.

Small investors versus hedge funds.

It is the short version of a story that is currently of concern to the stock markets.

A story with crazy twists and turns, as happened in the past few days around the shares of the US computer game retailer GameStop.

Small investors have reportedly taken a concerted effort to topple large hedge funds out of anger at their behavior. As is so often the case, the truth is a little more complicated. And many investors shouldn't be happy about that.
