S&P 500 - Medium Timeframe AnalysisS&P 500SP:SPXUnbieXAs illustrated, we appear to be in the final wave to the upside. At this stage, I’m treating Wave 5 as a standard impulse. However, given that Wave 4 retraced deeply, nearly to the termination point of Wave 1, there remains a modest possibility that this higher-degree Wave 5 in gray, which began in 2020, could ultimately unfold as an ending diagonal. That said, this scenario remains highly unlikely, as the internal structure of the preceding waves does not exhibit the characteristics of corrective price action.
