1/2法：
如一只股票从30元开始上涨到60元，那么45元(即：(30+60)/2)就是股价的第一个强烈支撑点，如果45元支撑不住，意味着该股票走入弱势格局。第二道关卡则是37.5元，(即：(30+45)/2)，一旦跌破则是熊的开始。个股如此，大盘也如此。一旦这只股票跌破第二道关卡，就要坚决出货。通过补仓摊低成本是不对的。反弹也可以通过此方法来判断。如60元的股票下跌到30元，则第一道反弹关卡是45元，若反弹超过45元还往上涨，就是强势反弹。第二道关口则是52.5元(即：(60+45)/2)，如超过则进入牛市。虽然市场不是100%绝对，但长期来看1/2法非常有价值。
当市场资金为多时，背景是偏红的，应该积极做为主。
