SPX has been trading a bit over the 161 fib of the March drop. This can be an area in which we see strong reversals. If you draw a fib from the high before the 2018 fall to the low before the 2019 rally, the fib of that comes in around where the SPX made a high in March 2020. And this has been a tendency of tops in the SPX/DJI/RUT/NQ (And everything, really) over 100 yrs.
And yes, I know there was news in March. I'd certainly not rule out it taking some might news to make these types of swings. News comes in market highs.
