New Idea

At last finance class, I learned some interesting thing. One is Rd(return of debt) is not same as interest rate but same as company’s bond rate. This is a very new thing because I always use interest rate. But in US, it is quite natural .When I use interest rate for Rd, order is Re > Rf > Rd. This is strange. No one lend money to a company because Rf is greater than Rd. Another thing is Beta should be calculated by 1 - 2 years data although I learned longer is better. Of course, from the view of statistical point longer is better. So it depends on purpose.Anyway, what I learned is those two.

By the way, I have a sentence I like to read.

"'I'm not talking about how you feel. At the very least I know I shouldn't have said things like that,' she blured out.
'Into self disipline, are we?'
'Well, I'm always trying' (qtd in haruki Murakami, Hear the wind sing 60)

Pride is not for others but for myself.
