Godfrey Daniel!, as W.C. Fields used to say, there are over 60,000, yep, sixty thousand, indices for just the US and Canadian exchanges. https://finance.yahoo.com/lookup/indices?s=^&t=I&m=US&r=1 And ETFs? Holy guacamole! 15851 world wide. https://finance.yahoo.com/lookup/etfs?s=^&t=E&m=ALL&r= Some that are not actually being traded anymore but more than enough to satisfy all but the craziest of us. Best, Allen
