A view on Equities vs. Gold since 1921: Will the tide turn soon?

This is a long-term view since 1921 for myself to check later and for all my followers who are interested.
You see periods where it was more beneficial to hold Gold and you see periods where it was more beneficial to hold Equities.
The question is, are we on the verge of a breakout to the upside, so that the tide will soon turn in favour of Gold, and how long will the phase last?
