The Science Behind Why We Hate Mondays

Why Investor Sentiment Matters on Mondays

Investor sentiment has a significant impact on the stock market, and this sentiment is not immune to the Monday blues. It is widely believed in the stock industry that the gloominess and pessimism among investors on Mondays can contribute to poor stock returns. Numerous studies have examined the “Monday effect” and have discovered that when factors are adjusted to control for investors’ moods, the impact of this phenomenon diminishes. However, it is still evident that there is a strong correlation between collective pessimism among investors and financial challenges experienced on Mondays.


Higher Stroke Risk on Monday Mornings

Studies have established a direct correlation between stroke and high blood pressure. However, research has also revealed an interesting connection between an increased number of strokes on Monday mornings, specifically between 8 AM and noon. Numerous studies conducted over the years have consistently shown a higher probability of various types of strokes occurring on Mondays. In fact, a study carried out at the Boston University School of Medicine discovered that the highest number of stroke events took place on Mondays, particularly among working men.
