Big tech's big day
It's not like it's common to see a large selloff the day after traders were popping corks to celebrate another all-time high, but it's not all that uncommon, either. Below, we can see every instance when the Nasdaq 100 closed at an all-time high one day, then suffered a 2% or larger loss the next. It tended to precede some more weakness in the very short-term, but not much after that.
