I am not consider book value in my buying because some sector like IT stocks have always low book value and banking stocks have always higher book value.
If this stock down below 125 and you use reverse trading system (read my book for this ) then we use book value to buy it again below 100 as a value buy.
So If you are a trader then please note this stock is not breakout yet and traded below his 200 DMA. If this stock cross price of 200 in up-trend then it may give decent trading run. Long term investor like me not see price of stock regularly so I am not hesitate to buy at CMP and stocks which traded below 200 DMA
10. Base price of Kirloskar Brothers Ltd is 190.35 So CMP is near 10 % below from base price so as my theory If you buy below 15 % of base price means below 160 then it is a best price for long term
