In market microstructure/high frequency finance, it is well known that the trading day has high activity in the opening hours and closing hours compared to mid-day. Can the same be said about the trading week, in that markets on Mondays and Fridays are more active than Wednesday as people open/close their positions at the start and end of the week?

  • $\begingroup$ the trading day having high activity in the opening and closing hours compared to mid-day has become a stylized fact observed in hundreds of assets. I just want to see if the trading week also reflects as a stylized fact in the low-frequency theory $\endgroup$ – develarist Jun 24 at 8:35

It looks like there is no impact on the volume of transactions depending on the day of the week if we refer to this chart: https://www.quora.com/What-is-the-average-total-number-of-trades-daily-on-NASDAQ#:~:text=What%20is%20the%20average%20total%20number%20of%20trades%20daily%20on%20NASDAQ%3F,-ad%20b&text=http%3A%2F%2Fwww.nasdaqtrader.com,daily%2C%20around%2010%20million%20trades.

The only "race" that exists is at the end of the year, and it lasts for the last days/weeks of the year.
