"The weekend effect is a phenomenon in financial markets in which stock returns on Mondays are often notably lower than those of the preceding Friday. An anomaly is when the actual result under a given set of assumptions is different from the expected result."
However, some traders and investors believe that markets tend to trend downward on Mondays. This can mean much lower returns on Monday than there were to be had on Friday, making Monday traditionally known as a good day of the week to snaffle up potentially undervalued stocks and indices.
