It's Halal to trade CAC40 S&P500 or NASDAQ?

Salam Aleykum,

I want to no if it’s halal or not to trade (without leverage) stock index (CAC40 S&P500 or NASDAQ…)

Thank you in advance for your answers !

Here is a good explanation about when it is halal to buy stocks of a company:

Index is simply a collection of stocks. Unfortunately a lot of companies in many stock market indicies do not satisfy above conditions. Depending on where you are located, you may have access to ETFs that filter out non halal components.
