The market never changes because people never change. It is always propelled by the desire to make money and the fear of losing money. Everything else is just a guise to give people the confidence to make and stick with their gambles.
Fundamentals, irrelevant. Whose to say that a company that is growing in whichever metric (usually the best one gets cherry picked.) Has to have the share price go higher? It doesn't have to do anything. People have just been conditioned to follow the rules of FA and bid it up. The same is true, especially true in TA. People see what they want to see. Its all just used as a tool for people to make the decisions they do. At the end of the day no one knows what the market is going to do next.
The same human elements will always propel it. The market will always fool the majority. When it's going up people will be blinded by greed. When its going down people will be shaken with fear.
This process will repeat for eternity.
