Bro, understand that you're a deep value investor that only aims for counters trading below book value. But some of us are growth investors who prefer businesses whose earnings improve year after year in both good times and bad. That is why people are willing to pay a premium for such counters.
There is no one method to rule them all when it comes to investing
I do buy growth stocks too like banks and comfort delgro/singtel
but I do have some rules in place to prevent be from over paying for growth stocks
generally the max I pay is around 15 times forward earnings and nothing more
like CDG and ST is my upper limit already
you can look at growth stocks that were at lofty valuations like super group, Sarin, OSIM, silverlake axis... when earnings growth fizzles and earnings came in flat or negative.. the stock will get sold down very hard
thats one big risk of owning growth stocks
generally growth stocks are more risky than dividend stocks
however picking right growth stocks can make u very rich, example challenger that i bought
