With the recent news of the FED being close to a new rate cut, it's important to start considering the possibility of the market going even higher. However, it's hard for price to keep pushing up when it's already overextended. Not saying this doesn't happen because it does. Price does tend to break the rules of statistics, given the irrationality of people. However now that most stocks are currently in an uptrend, it's hard to believe this performance will continue for much. It's likely that several stocks will begin to start forming downtrends, pushing the percentage of stocks in an uptrend down. When looking at the chats, the cyclicality of growth spurts is quite notorious. However, not every time that a down turn in the index is followed, the vast majority of stocks being in an uptrend.
Although this does tend to happen, as I've circled here in many examples. However, other examples don't show this same pattern and instead see price move even higher. This is because using the percentage of stocks in an uptrend as an indicator is not painting a full picture. Even if many stocks being going into downtrends, the force and extent of which these trends form is what actually drives price action in the index. So we should expect several stocks to begin underperforming in the next couple of days. But if the stocks that have just recently entered an uptrend keep providing strong results, it's still possible for the index to keep on going higher. The direction of the index will depend on the strength of the new form trends and the soon-to-be formed downtrends.
