I am required to perform a share valuation for Domain Holdings Group Australia for one month from 05/06/2021. I am unsure of the best way to go about this.

I have an extensive spreadsheet forecasting the business from a previous assignment but it is all done year by year.

Mostly I would like to know what values needed e.g. cost of equity, dividend amount moving forward etc., and how to go about figuring these out.

Any help would be appreciated! Thank you!
