MARCH 8th, International Women’s Day, always brings a flood of reports about gender inequalities in everything from health outcomes to pay and promotion. But one gap is gradually narrowing: that in wealth. As money managers seek to attract and serve rich women, and as those women express their values through their portfolios, the impact will be felt within the investment industry and beyond.According to the Boston Consulting Group, between 2010 and 2015 private wealth held by women grew from $34trn to $51trn. Women’s wealth also rose as a share of all private wealth, though less spectacularly, from 28% to 30%.
