Post PE seems wrong on CG - it's at ~16 PE. There's a good interview online (same channel as Atmastco one) explaining the biz well. Is not a very complex biz and promoter doesn't have grand vision, so not exciting long term.
More complex ancillary biz in real estate like Facade players are trading at <20PE despite great growth. It's a small sized BSE SME so high chance of flippers, which gives scope for pop & post-listing move.
Final Verdict - Not going to apply here, blocking some funds in other open IPOs. The only reason here would be size of the issue and allotment would be very very difficult.
Nothing wrong with fundamentals, but again, if allotment is so tough, I would not like to block funds in such case.
