There's a lot going on in making an investment decision. And we all bring our own unique background to it. In another life I was a student of Dr. W.Edwards Deming and his methods of quality management. The essence of what I've carried over is this: Information is not knowledge. Knowledge depends on theory. Having experience in buying/selling stocks teaches us nothing unless one puts it up against a theory of and about valuation. To me, a theory means something concrete I can objectively look at, and that leads me to a requirement for a formula. At this point, being still a work in progress, I'd rather not focus on the contents specific to my formula. As I say, it all might be irrelevant anyway. Take NVS, for which I ask your opinion (and of others who might be following it). It has a 19% net profit margin and 21% operating margin currently (latest Yahoo numbers). Over the past ten years it's averaged 17.7%. Psr is relatively low at a little over two, stock is hitting 12-mo. low, p/e at 11.4 (ttm)is at low compared to past yearly averages, dividend yield is over 4%. I am considering making a small buy. Would such a stock be so low in price that it would fit anybody's model/formula, assuming they used a model or formula? Fits okay for me regarding profit margins. Regarding 17.7% ROE, that is marginally okay at current stock price, by my calculations. Where I sense I'm really weak is, if given that NVS is cheap, and if capital to be allocated is limited, where does NVS stand in relation to all the other cheap stocks that are comparable? Perhaps other big pharma's are cheaper and better buys. SI shows "P/E as % of Sector Segment" = 85%, so NVS seems to be in the ballpark with other pharma's (as regards p/e). There still might be cheaper better buys out there though.
