S&P 500 is back in the Bollinger Bands

The S&P 500 is finally back to within a relatively tight set of bollinger bands. You can see that it was trading above the bands on the way up, and below the bands on the way down, and occasionally traded in the bands when it looked to change direction (Oct 2021, April 2022, & August 2022). It has been largely trading within bands since October 2022.
