Lol, it's clear you don't know what you linked to. This is not the Rothschild family's investments. This is an investment adviser named Rothschild Investment Corp. It's an SEC-registered investment adviser that caters to retail investors as well as high net worth investors, charities, pension funds and corporations. The 13F holdings you linked to are holdings the investment adviser has bought on behalf of their more than 1000 clients while rendering investment advice. Again, not the Rothschild's personal money.
