In this idea, I'm simply taking a look at the S&P 500 verses the actual stocks that make up the S&P 500 by using their 200d and 50d averages. This can be useful as an indicator to look for divergences, early warning signs, or confirmational trend changes.
Top pane = SPX stocks above their 200 day moving average
Middle pane = SPX stocks above their 50 day moving average
Lower pane = SPX index
Since May 2021, it's evident that the stocks > their 200 day and stocks > their 50 day have been trending down while as the overall index has been trending up. This is a sizable divergence that could cause a sudden correction in the index. While I'm speculating, I do not believe the indices have put in their major top yet. But that doesn't mean we will not see a sizable correction with weeks or months of volatility. Let's see if the indices can take a chill pill for a while and offer another buying opportunity.
