I believe this pattern has something to do with tax seasons. If you sell at the start of January, you have a whole year before you have to pay the capital gains tax on the profits, which leaves traders with plenty of time to put that capital to use and make even more returns.
Doesn't that make sense?
Yep, I am just surprised if it is partly due to tax related selling, we don't see a drop closer to the start of the year. For example on the first couple days of January?
Woah! You may have solved this riddle...
