Intrinsic value is a difficult number to calculate, because it involves so many assumption, which might or might not be valid in future. DCF calculation requires the user to predict future growth rate of the company, which we know for sure that no one can predict.
I find “the concept of margin of safety” a better proxy to intrinsic value. In margin of safety, you try to buy stocks which have lower downside (lower probability and lower downside) and significantly high upside potential and probability.
I know no quantitative way to find the probability and potential. The qualitative way of finding such stocks are looking for parameters like
1> Cheap valuation parameters (like pe, peg ratio, divident yield, cash yield, roe, roce, growth)
2> Good moat
3> Excellent management track record
4> New change in business environment, which is going to effect the company in a big way
