noise trader การใช้

According to some economists, individual traders could act as " noise traders " and have a more destabilizing role than larger and better informed actors.
This problem only becomes more severe when the noise traders behave socially and follow each other's mistakes by listening to rumors or imitating their neighbors ( Shiller 1984 ).
This trade takes place between what Black calls " information traders " and " noise traders ", where the former operates based on accurate information and the latter trades based on noise.
Unfortunately, there is no way of precisely parsing the noise and information from a data stream or signal, so the so-called noise traders tend to think that they, in fact, trade on information that others in the market simply reject as noise.
It is seen that a stochastic strategy with probability of choosing the same restaurant ( as the one chosen last evening ) going inversely with the number of players who made the same choice last evening, and choosing others with equal probability, gives better result ( giving utilization fraction about 0.79 ) than deterministic or simple random choice ( noise trader ) ( with utilization fraction = 1-exp [-1 ] ~ 0.63 ) strategies.
