Did you know this in Trading?

@grok elaborate and explain

The idea of weekly stock market patterns, like Friday lows being revisited on Monday, stems from research on the "Monday effect," where Monday returns are often lower. Studies, like one from 1973 in the Financial Analysts Journal, suggest this might happen due to factors like bad news released after Friday's close. Trader psychology and trading volume also play a role. However, the reliability of these patterns for trading is debated. A 2017 Arizona State University study questioned the "weekend effect," suggesting it's not consistent. Analysis of S&P 500 data from 2000-2024 shows day-specific patterns, but they lack practical significance for investors. The efficient market hypothesis also argues such patterns might just be noise, not predictable trends.
