By analyzing data and expert insights, we aim to shed light on this intriguing market behavior and equip you with the knowledge to navigate the Monday market with greater confidence.
Unveiling the Monday Effect: A Historical Perspective
The concept of the Monday Effect first emerged in 1973 when Frank Cross, a financial academic, published a groundbreaking article titled “The Behavior of Stock Prices on Fridays and Mondays” in the esteemed Financial Analysts Journal. Cross meticulously analyzed data from the New York Stock Exchange (NYSE) spanning the years 1953 to 1970, meticulously pairing each Friday with its subsequent Monday.
His findings were both intriguing and statistically significant. Cross discovered that Friday often emerged as the best-performing day for the S&P 500, with the index rising a remarkable 62% of the time. Furthermore, following these 523 winning Fridays, the S&P 500 continued its upward trajectory on the following Monday a staggering 49% of the time.
However, the Monday Effect did not solely favor upward trends. Cross also observed that on the 313 Fridays when the stock market closed lower, the odds of the S&P 500 declining on the subsequent Monday tilted heavily in favor of a decline, with a 3:1 ratio
Unraveling the Enigma: Potential Causes of the Monday Effect
While the Monday Effect has been observed and documented its underlying causes remain shrouded in a degree of mystery. Several theories have been proposed to explain this phenomenon, each offering a plausible explanation for the observed patterns:
1. The Short-Selling Hypothesis:
This theory posits that short-sellers, who profit when stock prices decline, tend to cover their positions on Fridays before the market closes for the weekend. This concentrated selling pressure could contribute to a downward trend on Fridays, followed by a rebound on Monday as short-sellers repurchase shares to close their positions.
2. Market Sentiment:
Market sentiment can fluctuate significantly over the course of a week. As the weekend approaches, investors may feel more optimistic and confident, leading to increased buying activity and higher stock prices on Fridays. Conversely, the anticipation of the workweek and potential market uncertainties could dampen sentiment on Mondays, leading to a decline in prices.
3. News Release Strategy:
Companies often strategically time the release of negative news
