In its recent article "The power of money" on gender and investing, following International Women's Day on the 8th of March, the Economist observed that women's share of private wealth has been rising and will reach 32%, or USD 72T, by 2020 (BCG). Women tend to be more risk-aware, are more likely to buy and hold, and are more critical of their asset managers than men. 84% of women are interested in sustainable investing, compared to 67% of men, though the latter is changing with millenials (Morgan Stanley). USD 1.3B was raised by mid-2017 for gender lens investing across asset classes (Project Sage), and there is a correlation between women representation in senior management and a company's better performance (RobecoSAM).
