Best long term investments?

According to Ray Daly and Andy Gupta the best way to invest is to have 10-15 diversified index funds that are non correlated . Do you know what are the best islamic index funds with the least management fees

That’s a large number of index funds to hold. There’s no such thing as not correlated, just more or less so. The least correlated I found among sharia filtered funds was between AMAPX and any of the other funds.

SPUS and HLAL are both half a percent last I checked. I hope to see those fees drop in the future.
