My approach is generally to look for companies that have recurring business models. From my experience estimating future cash flows is a lot easier when a high % of them are recurring in nature. By way of example an insurance company has about 80-85% of its customers renew year after year, so at the beginning of each year you can get a rough estimate of what premium income will be for the year (of course there are a myriad of variables that may change this). In these sort of recurring business models the cost of customer acquisition is also low (80% of your customers are coming back without any cost) which means the business can grow using less cash. At the other end of the spectrum would be contracting businesses that I generally class as speculative, only because without being able to sit down with management it is very difficult to know how the business is tracking.
To determine whether a company is undervalued, I use a mix of DCF and an absolute P/E model. The P/E model can be good for getting a ball park number and the DCF allows me to get in a bit deeper and understand what drives cash flow. I come up with a price range, then look for a margin of safety in case things go wrong. In the spirit of Greenwald, I don't like paying for growth because I really don't know whether it will eventuate. I think one of the biggest mistakes many investors make is paying for blue sky, IMO that should be a bonus.
It's quite a simple strategy, but it gets the job done. For some reason I also find a pen and paper gives me a better understanding of a company than a computer does. Weird.
Hi McLovin
Great post – well at least it certainly resonates with me.
Not sure why everybody thinks DCF is so tricky – it’s not like you have to do the calcs longhand any more. And if you put valuation at the end of the research process where it needs to be so that you have the best chance of making realistic assumptions, you probably won’t be doing that many valuations anyway.
In relation to paying for growth – I will include short term growth on a risk weighted basis accoring to it's certainty but I don't generally put growth into any terminal part of the calc, unless it is something like WOW where I would use a conservative estimate of GDP. Greenwald should be mandatory reading for Investors.
I agree that once you know a bit about what you are doing the back of an envelope with a few shortcuts can give you a pretty good pre-emption of what the full works analysis will come out at
