The answer to this question is that there are SO many different factors that play a role, and which lead to more factors to affect the market. While you will be analysing what is going on, and try to predict what might happen in the future, you cannot really factor in everything as there are so many things and influences on the market. All these variables make the prediction quite hard, but you will always need to do your best so as to improve your chances of choosing well and deciding in the best possible manner. There is also the market sentiment to consider.

Predicting the stock market is notoriously difficult due to its inherent complexity and the multitude of influencing factors. Market movements are driven by a mix of economic indicators, corporate performance, geopolitical events, investor sentiment, and unforeseen events like natural disasters or pandemics. The interdependence of global markets adds another layer of unpredictability. Additionally, behavioral economics shows that human emotions and psychological biases often lead to irrational decisions, further complicating predictions. The vast amount of data and the dynamic nature of these factors make accurate and consistent predictions exceedingly challenging, even for experienced analysts and sophisticated algorithms.
