“A major cause of higher price is higher prices; but when the trend is reversed, then lower prices lead to still lower prices. To buy when others are despondently selling and to sell when others are avidly buying requires the greatest fortitude and pays the greatest ultimate rewards.”
— Sir John Templeton
“推高股价的一个重要原因是价格在不断上涨；而当趋势反转时，价格的持续下跌又会导致股价创出新低。在其他人沮丧时买入，并在其他人狂热时卖出，需要极大的克制力，回报也最为丰厚。”
— 约翰·邓普顿爵士
