Key Takeaway

Recovered same day, new highs within months

“It’s human nature to do things in groups. This is extreme in markets. I’ve seen first hand large allocators who, as an organisation, seem to prefer losing money in a conventional way, than making money by themselves.”

“The market isn’t efficient or inefficient. That’s too simple. To me it’s just a thing, made up of players each of whom have different goals, different time horizons and different strategies.”
