Aim is more miss than hit for investors as it marks 20th anniversary [2015]

This FT article dates from June 19, 2015. AIM launched on June 19, 1995 - hence this was a 20-year anniversary piece.

It's paywalled, but AIM is the London Stock Exchange's less regulated sibling, the Alternative Investements Market, and the main claim from the article is:

> "close to 3,000 companies have listed on Aim, but 72 per cent of them have never produced a return for investors, according to professors Elroy Dimson and Paul Marsh of the London Business School. Worse still, nearly one in three Aim companies have resulted in shareholders losing 95 per cent or more of their initial investment."
