First, let's take a look at the market performance before and after the "four Witch Day" in history. it usually goes like this: on the Thursday and Friday of the week before the "four Witch Day", the major indexes of US stocks are more likely to rise; after the end of the four Witch Day, the chances of each index falling will rise.
For example, the overall performance of the S & P 500 between 2018 and 2020, with the red circle representing the arrival of the four "four witch days" each year, can clearly see the frenzied growth in trading volume.
But specifically, if S & P closed down on the "four Witch Day" day, US stocks would probably hit the street on the first trading day of the following week; if they closed higher on that day, US stocks could either rise or fall.
Through the statistics of the trading volume and the rise and fall of the trading volume of the four witch days and before and after the two trading days in the past three years, we can find that the trading volume of the four witch days has been significantly enlarged and mostly closed down.
So how should investors prepare for the "four Wizards Day"?
To sum up, the positive impact of the "Siwu Day" on the market is that the carry trade brings profit opportunities, that is, the increase in trading volume may lead to a rise in the market. On the negative side, history shows that profitability will not improve, market gains are usually small, fluctuations bring gains, but losses are also obvious.
For long-term investors
You don't really need to care about short-term price changes, especially the "four Wizards Day", which takes place every three months.
And long-term investors should think more clearly about their own initial.
