Women have different financial strategies and insight than men, argues Sallie Krawcheck, the co-founder and CEO of Ellevest, a digital investment platform for women. Female investors have a different sense of why they want to make money, pursue specific goals more readily, and show a unique sense of risk awareness. Krawcheck says it's important for women to play the market and plan financially because there is a real retirement savings crisis in this country which disproportionately affects them.
