PER, PBR 다 따졌는데, 왜 내 돈은 물릴까요?

Today's content is about PBR, which you all encounter the most. What is PER, you ask? Simply put, ten times is cheap and fifty times is expensive; actually, you have to be really careful about this when doing PR [for music]. Just doing this alone makes you a bit more professional, so hello. This is Week

3 of the 7th Cohort of the "Think Together" class. I am discussing the understanding of investment—specifically, the basic concepts and theories necessary to understand the stock market— from my own perspective . If you try to gradually review the things you heard in the first and second weeks, you might think, "Well, will this really be helpful right now?" but actually, they will suddenly

you encounter the most. I’d like to talk to you about things like ROE . The reason I said this is because people these days say the stock price is undervalued and has gone up since PR is cheap . Anyway, putting all that aside, we need to apply PBR. Well, you have to apply PER. Actually, the

funny thing is that you have to think of PBR and ROE as a whole . Basically, the fundamental formula is that PBR is ROE * PR. What is that PER? What happens if I do this? It is the PBR divided by R. There are also people who approach it this way, but I do a lot of multiplication thinking

. So, for example, let's say we have companies A and B, and the PBR of these companies is extremely high. That is PBR, and what is the difference? The difference between the two is that R P is the same. PR is the same, but it's because of P RO. These Rs show something like profitability, but
