REPCO home finance – another Gruh in the making?

I had read smbdy saying this before as well on the forum (i.e. valuing on pe basis).

I thought then, that would try to find and read about this thought process on google, but haven’t been able to do so as yet.

I am not saying that P/BV shud be used in isolation but shud be used in the light of other factors stated. I am able to reconcile with why P/BV is or shud be used. Could you please guide me to some references about this on the net (use of PE) if you have come across any good reads on this. I would like to understand more as to why PE should be used and the differences there off.

Thanks.
