Quant investing, in all its various forms, has been one of the growth areas in fund management over the last two decades. In this podcast Dr Sean Phayre, Global Head of Quantitative Investments at ASI, reflects on this growth and the reasons for it. Speaking with Richard Dunbar he also reflects on the recent underperformance of “value” as a style, the changing nature of the companies in which we invest and on how and whether ESG and “stewardship” fit in to these styles of investment.
