"Witch Friday" - the day when quarterly futures on indices and stocks expire - somewhat confused the U.S. stock market participants, which led to a mixed closing of the last trading session of the week. Traditionally, this day is marked by increased volumes and sharp, irrational movements in the value of exchange assets, especially since the last, December expiration always has the highest volume. This Friday was not an exception and managed to "slow down" the ardor of buyers. In normal times such a "meeting" could lead to a corrective movement, but, as we said, many investment houses will start preparing for the holidays starting this week and will pay much less attention to the trades than usual, which can keep the market from going down, putting it in a sideways movement with insignificant intraday changes.
