我在做官网的题库 里面答案有这么一句解释，我觉得不对，因为RI法减去的只是cost of equity，而且用RI必须要预测ROE，earnings on equity，这不就是相当于在预测future earnings growth么？
The residual income model, also called the excess earnings method, does not have the same weakness as the FCFE approach, because it is an estimate of the profit of the company after deducting the cost of all capital: debt and equity. Further, it makes no assumptions about future earnings and dividend growth.
