A trio of activist investors is targeting big U.S. financial institutions in 2017, demanding they disclose compensation data for men and women, and publish statistics about the race and gender of their employees. Goldman Sachs Group Inc., Citigroup Inc., Bank of America Corp. and Wells Fargo & Co. are among the companies in the sights of Arjuna Capital, Trillium Asset Management and Pax World Management, which say a diverse workforce produces better results. Though the investors are relatively small, each managing a few billion dollars, they have succeeded in pushing technology goliaths such as Apple Inc. and Intel Corp. to divulge information about pay gaps.
