Question

I'm doing financial model (to forecast revenue and cost), but there is no historical figure to be based on. Can i use comparable companies figure? Or Can i use some judgement or realistic figure for the first 5 years (certain) and use these variables to forecast another 15years (uncertain) using regression?

Answer 1

The answer is yes to both options... Ultimately, you are making forecasts for the future and you have to use whatever information you have - historical, fundamental, industry wide, judgment - to make your estimates
