股价的涨跌,若从经济学的角度来说,是由市场的供求关系所决定。但在股市的初期(不成熟阶段),这种供求关系却带有很大的人性色彩,由某个集团或机构制约着这种供求,使之造成极度的不平衡,导致股价的大起大落,从而操纵市场价格。那么,这些集团或机构,在股市上便称为主力或庄家。 Price changes, if from an economic point of view, is determined by the market’s supply and demand. However, in the early stage (immature stage) of the stock market, the supply-demand relationship is very human-natured. Constraining such supply and demand by a certain group or institution causes an extreme imbalance, resulting in a drastic rise and fall of the stock price. Manipulate market prices. Well, these groups or institutions, in the stock market will be called the main force or banker.
