According to S&P Global Market Intelligence president Martina Cheung, about 50 percent of S&P 500 companies do not disclose diversity metrics to investors. She said gender reporting is falling behind and sometimes the diversity reports are inconsistent.

This is a problem for investors focusing on women. Cheung added that some investors are forced to use machine learning, text analysis and big data to mine information about gender diversity in companies.

Gender lens investing has doubled to more than $4 billion in 2018 and women globally are projected to control $72 trillion in wealth by 2020.
