Take this representative quote “It’s Jerome Powell’s world: never before have I seen markets move so erratically in response to a once-boring Jackson Hole conference. Actually, the first time I ever heard of this event was this year since some acquaintances of mine were trying to ‘trade’ it.”
So, essentially, this person had no clue what Jackson Hole means in the financial world but makes a huge judgement on past events, then says immediately they know nothing of the past and just learned of them this year. No analysis of market volatility around these events, just a blanket statement that makes them look foolish.
Basically they are now opening their eyes to the huge role central banks play in the economy.
