The answer again is yes.
The ETFs are available to you through some specific brokers and they are available as fractional shares.
If you dont know what EFTs are then you should know that ETFs are index funds that can be traded throughout the day just like stocks.
And traditional index funds can only be bought and sold for a determined price at the end of each day.
Each ETF can very easily diversify your portfolio. So thats definitely a point. And by buying multiple ETFs through fractional shares you are adding yet another level of diversification to your portfolio which you should do soon or later.
