What is DCF?
Discounted Cash Flow (DCF) is the gold standard for absolute stock valuation. Unlike P/E ratios which are relative, DCF estimates a company's intrinsic value based solely on its ability to generate cash in the future.
Future cash flows are estimated and discounted to calculate their Present Values (PVs). The sum of these PVs, combined with the Terminal Value, determines exactly how much the asset is worth today.
The core philosophy: A dollar today is worth more than a dollar tomorrow. We "discount" future cash back to today's value to see what the business is really worth right now.
