The notion that human behaviour drives stock markets is not new.
It is human behaviour that drives a stock price up when the stock market investors believe that a listed company will be very successful, and this will translate to an increase in the share price.
The reverse is also true, when the sentiment with investors is that a listed company will not be successful then those investors that hold that share will sell that share and thereby increasing the supply of the share price in the market and then the share price will decrease.
