The Financial Times of 15 July 2013 reports 'smart beta' strategies could reach one-third of all equity allocations by 2017.
Smart beta strategies aim to provide better performance (lower risk or higher returns) than cap-weighted indexes by weighting market according to other factors, such as economic fundamentals. They are niche plays at the moment, but Morningstar and Lombard Odier both predict a rise towards one-third, which would be a massive equity allocation change.
