You have to remember that each day millions of people/investors will make decisions that when put together will shape the “market”. Obviously millions of people will have various different reasons/inclinations for their financial moves. For someone to then sit back at the end of the day and think they know why millions of different decisions were made, is ridiculous. Now, sometimes there are major factors/events that can happen and cause things to move in a particular direction but the majority of the time, especially on a day to day basis, the market is subject to immense variations in strategy or approach. Then when all of those are added up, you have your “market”.
