No. Because that isn't what they do (I am talking about fundamental investors: Marshall Wace, Point72, etc.). I have no real idea what they do or do not do but they trade over shorter time frames where there is no change in fundamental information (i.e. they are trading based on liquidity signals which is, essentially, what market-making is now).
