In this exclusive interview, Greg discusses the challenges facing active equity managers amid narrow market leadership and index concentration, including how idiosyncratic volatility and dispersion across sectors, countries and at the single stock level are shaping the way he manages equities portfolios. Greg shares his perspectives on the impact growing allocations to quant strategies, the rise of multi-manager hedge fund platforms and the increasing participation of more active retail investors are having on how discretionary managers invest in equities and what he sees as the best pathway for alpha generation in the current market environment.
Watch the full interview where we ask Greg:
What challenges do active fund managers face given the narrowness of equity market leadership and index concentration?
How does idiosyncratic volatility and significant dispersion across sectors, countries and especially at the single stock level influence how you manage your equity portfolios?
How are increasing allocations to quant strategies, the growth of multi-manager hedge fund platforms and the rise of more active retail investors impacting how discretionary managers invest?
Taking into account the evolving market landscape, do you believe in a dedicated style approach to investing in equities and what do you see as the best pathway for alpha generation?
