I used to focus too much on the “numbers”, while they are very important, and the price you pay is VERY important, I learned from WEB & Co, it’s EVEN MORE important to get the business right. That is Waaaay more crucial than your discount rate.
SPEK, yes, looking backwards to see what growth rate is required to justify the current price, might be a better way to look at a DCF If you aren’t susceptible to creeping growth rates. Which I think most market participants waaay over estimate growth over the long pull.
