I’m pretty sure gold is the only asset that’s at it’s all-time high right now. The important thing to keep in mind is that it’s holding it’s position as other assets jump around from 50% to 75% of their highs. Gold does very well in times of economic uncertaintity. The world thinks of it as safe money.
I think we’ve got this in spades and will continue to have it for some time.

If you measure gold/commodities, you can see that it slides in value during heavy economic growth and rises during heavy economic turmoil.
