Yes, it is part of the strategy carried out by big investors because they rotate large amounts of money so it can be very easy to carry out such a strategy at any time they want, which of course is to get profits and secure the capital they have used.
It is usual that investors will really extract what they can with their capital and that is to make money out of it.
Such investors have been known to take only profits and they have no plans of losing and that's why they know how to do it. Buying at the dip and selling at the top. The rinse and repeat strategy.
But they handle it with discipline.
