A gender equality ETF is an Exchange Traded Fund that invests in companies that promote gender equality and diversity in the workplace. These ETFs are typically composed of companies that have policies that address gender bias and have a diverse board of directors. The goal of these ETFs is to promote gender equality in the workplace, while helping investors gain exposure to companies that promote these values.
Used in commodity ETFs, this is when a trust stores the physical commodity (usually gold or silver) in a vault. By owning shares of that ETF you are entitled to claim some of the physical commodity. Trusts are designed to protect the assets and income of the grantor so that the investors can receive them.
