Sir, its really a great contribution toward my research question. thanks for your honest effort and contribution.

Poonam Rani , hello I want to ask about your journal - Underpricing, Firm’s Accounting Information and Grading of IPOs: An Empirical Analysis of Indian Private Sector . Is the underpricing really the independen variable? not the dependend variable? because your hypothesis say so. I'm hoping to hear from you soon, thank you

Under pricing is dependent variable

its it out come of information asymmetry, firm characteristics and some time it depends upon the underwriter as well . There are other macro economic factor as well besides it some time the market condition also contribute towards under pricing.

I have made the hypothesis from a different perspective.

@poonamrani thank you for the answer. It helps a lot! Have a good day!
