An increase in the stock price of steel manufacturers suggests an increase in the demand for steel, which induces entrepreneurs to start more steel plants and investors to provide them with the money. Conversely, a decrease in the stock price of steel manufacturers leads entrepreneurs to liquidate existing plants and dissuades investors from committing more resources to the sector.
在股票价格上也是这样。钢铁企业股价的上升预示着钢铁需求量将会上升，这将指导企业提高钢产量，同时投资者也会向钢厂提供更多的资金。如果反之，钢铁企业股价的下跌预示企业要尽快清空库存，并且告诫投资者停止向钢铁行业提供更多资源。
