Critics of this approach assert that this is a very basic form of valuation and construe the method to be excessively simplified due to its highly simplistic assumptions. The proponents of the concepts of multi-period discounted cash flow models argue that in this dynamic and innovative environment (wherein each company is characterized by a unique and innovative business model that cannot be easily replicated or copied by others), it is difficult to find a comparable for every company. The stock markets cannot be determined to be perfectly efficient and the problem gets complicated in the stock markets of emerging economies. Since the markets cannot be assumed to be perfect, there is no assurance as such that the market value of a particular stock is accurate as inefficiencies in the market are factored in the prices of the security also. This would lead to mispricing in the market value of the comparable being transferred into the intrinsic value of the security also which is being valued. Several analysts hold the notion that this approach can be deemed to be suitable to determine the terminal value of the companies at the end of the sustainable competitive advantage period, which witness supernormal growth rates during the time of valuation, but in the long term, its growth rate would be close to the average growth rate of the industry as a whole.
这种方法的批评者认为这是一个非常基本的形式和分析评价方法过于简化，由于其高度简化的假设。对多期的贴现现金流模型的概念的支持者认为，在这个充满活力和创新的环境（其中每个公司的特点是一个独特和创新的，不能被轻易复制或复制别人的商业模式），这是很难找到一家公司可比。股票市场不能确定是完全有效的，问题在新兴经济体的股票市场复杂。由于市场不能被认为是完美的，没有保证，这样的一个特定的股票的市场价值是准确的在市场低效率的因素在安全的价格也。这将导致在可比被转移到安全也正为内在价值的市场价值定价错误。一些分析师认为的概念，这种方法可以被认为是适用于确定的可持续竞争优势期结束公司的终端价值，见证了超常的增长率在评估的时间，但从长远来看，其增长率将接近行业平均增长率一个整体。
