> I see this as, everyone bought on the news that the fed would begin tampering down rate hikes in the near future.
But this pattern has occurred over and over again in the last 4 rate hikes. You are suggesting that people haven't learned their lesson yet, which seems absurd to me. This is the 4th consecutive rate hike, with the numbers (0.75 increase) exactly the amount everyone expected.
It seems more likely that the people "buying at 2pm" today were covering hedged bets (such as selling off their put options, bought to protect against the volatility today).
The fundamental question is whether or not you want to believe that these buyers (and sellers) knew what they were doing. I think its more likely (than not) that they knew what they were doing, and favor the stories that have that mindset.
