We can talk “fundamentals” for ever. But the point is that as long as CB are able to print toilet-paper and turn it into something “valuable” by inflating bubbles here and there, there is no other “fundamental” that can cope with it. You may have thousands of TESLA in your stock markets, and yet get the value of those stocks increase indefinitely.
You only need to create a group on Whatsapp with Draghi, Powell, Kuroda and friends to allow them buy at the same moment and get markets up accordingly. As long as the Whatsapp group is in place, forget about “fundamentals”, “value”, “graphs” and all those middle-age relics. You just have to push a button, and buy. Whatever. Gold, oil, stocks, bonds, who cares. That’s the way to make money today.
