For example after Virgil has passed, OFF-WHITE not as interesting. Also after Steve Jobs died and now that Jony Ive has left Apple, Apple is no longer interesting.
TESLA remains interesting because Elon is still at the helm. Kanye West is still at the reign at YEEZY, which makes it interesting.
Also Amazon is no longer interesting, as Jeff Bezos has left the helm. Same goes with JAY Z selling Tidal (no longer interesting).
