Currently, I&m doing a project which is comparing 2 companies, one Japanese company and the other is an Australia company. I&m going to calculate the wacc of both. What should I use to calculate risk premium?

Many many thanks

首先这两家公司的所在的行业是不是一样的？

其次这两家公司在行业的地位是不是一样的？

还有好多好多可以考虑的方面，按cfai提供的分析方法，就是从整体经济－行业－具体公司，也许用这个思路可能能解开疑问。
