TY - JOUR AB - Purpose The Alternative Investment Market (AIM) is an important UK growth-focused stock market. The purpose of this paper is to assess the significance, risk-adjusted performance and portfolio diversification benefits of property companies on the AIM stock market over 2005-2015. The post-Global Financial Crisis (GFC) recovery of property companies on AIM is highlighted, as well as their performance compared with property companies on the London Stock Exchange (LSE) main board.Design/methodology/approach Using monthly total returns, the risk-adjusted performance and portfolio diversification benefits of property companies on the AIM stock market over 2005-2015 are assessed and compared with a range of other asset classes. Sub-period analysis is used to assess the post-GFC recovery of the property companies on AIM.Findings Property companies on AIM delivered poor risk-adjusted returns over 2005-2015, with limited portfolio diversification benefits with the overall AIM stock market. However, since the GFC, property companies on AIM have delivered strong risk-adjusted returns, with improved portfolio diversification benefits with the overall AIM stock market. This post-GFC performance is shown to be more than a small cap effect, reflecting the property portfolios in these AIM property companies. Despite this strong post-GFC performance, the AIM property companies under-performed property companies on the LSE main board on a risk-adjusted basis.Practical implications AIM provides an important platform for property companies seeking start-up and growth opportunities in a less-regulated funding environment. This has been reinforced by strong risk-adjusted performance in a post-GFC context. However, the stronger risk-adjusted performance of LSE listed property companies and their superior scale, resources and higher quality property portfolios present challenges for increased investor support for the AIM property companies going forward.Originality/value This paper is the first published empirical research analysis of the risk-adjusted performance and diversification benefits of property companies on the AIM stock market. This research enables empirically validated, more informed and practical property investment decision-making regarding the strategic role of property companies on the AIM stock market in a portfolio.
