I use the HUI along with many other things as indicator on when to sell or buy. There are no options or any direct way of buying the HUI that I'm aware of.
Currently I'm KGC, HL and WHT, but over the past year I've been in/out of NEM, SSRI, PAAS, HMY, BGO, DROOY, CDE, and MNG in addition to the previous three.
I consider KGC a core holding. The others come and go.
