My additional idea would be if or when we get struck by deflation (global), then perhaps we could see a further decline. It's possible that there may be a bottom closer toward 2021-10 through 2022-04. For example, the 2018 decline lasted 12 months; however things are different this time. So there is a chance that we may see 6 to 12 months of decline with short-term increases and flat sections. If deflation sets in around 2022-03 (even for 20 days), we could see something like the 2020-03 short-term drop and correction back up. However, this idea / trend that I am referring to can change by changes in inflation & deflation at any time; as well as unexpected economic shifts.
