Study of performance of women-led businesses
In 2015, Rubin published a study that shows that a hypothetical portfolio of investments in women-led companies would perform three times better than an investment in an index fund based on the S&P 500 over the same period. Her study was inspired by a Credit Suisse’s Gender 3000 report, specifically that "Companies with more than one woman on the board have returned a compound 3.7% a year over those that have none..." and yet paradoxically only "12.7% of boards had gender diversity."
