嗨,努力学习的PZer你好:


可以看一下business risk的定义,是sales risk和operating risk的combination。

我们已知operating risk是相同的,只需要看sales risk是否相同。

sales risk是销售价量的不确定性。而题目中只说数量是相同的,并没有对price进行限定,sales risk是不同的,所以business risk也是不同的。

老师,这里的operation risk是不是表述的有歧义呢?因为在Business risk下面的operating risk是指VC和FC, 但是另外又说Operating risk本身就是DOL,这个到底怎么理解呢?

没有歧义哈

结论:DOL 是 Operating risk 的一个量化衡量指标 "DOL is a quantitative measure of operating risk"

同学对 Operating risk 的「定性」理解是没问题的

首先:成本中固定成本部分越大,公司就越难根据销售的变化调整其经营成本。"The greater the fixed component of costs, the more difficult it is for a company to adjust its operating costs to changes in sales."

我们把固定成本和可变成本的组合所产生的风险称为经营风险。固定经营成本相对于可变经营成本越大,经营风险就越大 "We refer to the risk arising from the mix of fixed and variable costs as operating risk. The greater the fixed operating costs relative to variable operating costs, the greater the operating risk."

其次,DOL 是运营风险的一个量化衡量指标,可以说是「定量」理解。通过 DOL 公式,我们可以得出同样的结论

相对于可变经营成本,固定经营成本的使用越多,经营收入对销售单位的变化就越敏感,因此,经营风险就越大

"The greater the use of fixed, relative to variable, operating costs, the more sensitive operating income is to changes in units sold and, therefore, the more operating risk."

NO.PZ2016021705000038 不是很明白老师课上讲的 杠杆来源于固定成本。杠杆难道不是来源于借债么?用不属于自己的钱来赚钱,收益和损失都会放大。固定成本是不论接不接债一直都有的,这个杠杆是怎么说呢?又怎么理解 有固定成本的all equity的公司 的杠杆呢? L是EBIT变动1%,sales变动多少%,L为什么可以衡量杠杆呢?感觉只是简单的衡量两个指标变动的相关性,跟杠杆没有关系呀
