Can I buy NIMBPO without preconditions?

yes, just place your order or ask your broker to find a seller.
I am selling some NimbPo, are you interested in buying?

What’s interesting about this stock?

what is preconditions that you mean?

Don’t you have to be a current promoter to buy NIMBPO?

If there is no preconditions and we can buy same stock in lower rate, still why investors don’t buy promotor shares?
