I think most of them are self-fulfilling prophecies, to be honest, which means if the majority of the market still believes in it, it will happen regardless of the macro/microeconomic situation. Heck, some of them might analyze and try to fit any narrative to support it, even though it is not related at all.
Personally, I'd prepare for any outcome based on the chart. It isn't like you can prepare for both situations weeks before the supposed "destined" date happens. If you're a long-term holder who regularly buys or do DCA, though, I guess it doesn't matter since you'll still buy regardless of market situation. CMIIW.
