I 100% agree with you as an investor for more than 20 years when you say

Allocating assets with low or negative correlations helps investors lower portfolio risk. For instance, investing in both gold and equities can help offset losses if they have low correlations. Gold may increase in value as stocks decline, lessening the total effect.

I have been watching that big players keep on shifting their money from stocks to gold as the case be and the same is the case with cryptocurrencies. So when you see stock markets going down then you will see the gold and cryptocurrency marketing going up.

A nice study of the topic!
