Portfolio Theory and Value Investment
The core difference is the definition of "Risk". Portfolio theory takes "Risk" as the price volatility of securities. In contrast, value investment treats "Risk" as the inappropriate valuation of securities.
The underlying logic for defining "Risk" as volatility is the need of frequent measurement of asset portfolio in market value. The emphasis on the liqudity of security.
Value investor does not focus on market value of their holdings but rely on long-term value realization instead.
About The Timing of Selling
It is questionable that a value investor should sell a security when it reaches full value. As good asset provides long-term cash flows that are difficult to completely converted into current value based on available information. A value investor may rely on such assets to survive different economic conditions, especially downturns.
Invest for Certainty
A good value investment should involve certain judgement for key elements.
Uncertainty of future falls into several categories, internal uncertainty and external uncertainty.
Principal Obstacles to Success of the Analyst
- The inadequacy or incorrectness of the data
- The uncertainty of the future
- The irrational behavior of the market
Two Assumptions of Analytical Work
- The market price is frequently out of line with the true value
- There is an inherent tendency for these disparities to correct themselves
Market Modelling: Voting Machine instead of Weighing Machine.
The market price will not reflect the value of each securities in an exact and impersonal mechanism. Rather, it reflects the choices of countless individuals partly of reason and partly of emotion
Trend Essentially a Qualitative Factor
No limit may be fixed on how far ahead the trend should be projected; and therefore the process of valuation, while seemingly mathematical, is in reality psychological and quite arbitrary. For this reason we consider trend analysis as a qualitative factor in its practical implications, even though it may be stated in quantitative terms.
A Test of Distinction Between Investment v.s. Speculation
Safety: An asset is only safe only if it is assured, or at least strongly indicated, by the application of definite and well-estabilished standards.
Definition of Investment
An investment operation is one which, upon thorough analysis, promises safety of principal and a satisfactory return. Operations not meeting these requirements are speculative.
Past Performance V.S. Future Assessment
The traditional view was that prudent bond investing must be based on solid inference from past data as opposed to speculation regarding future events. However, the motivation of inferencing from past data was exactly trying to has know about the possibility of future.
Thus the real difference is really about whether we should judging a firm's future perspective based exclusively on historical data (concervative); or we can forward-looking at the quality and possibility of business.
Forward-looking analysis can be profitably applied to instruments of all sorts.
About Investment Risk
The supposed acturial computation of investment risk is hardly practical. Investment losses are not distributed fairly evenly in point of time, but tend to be concentrated at intervals, which is incalculable.
Four Principles for the Selection of Issues of the Fixed-value Type
- Safty is measured not by specific lien or other contractual rights, but by the ability of the issuer to meet all of its obligations.
- This ability should be measured under conditions of depression rather than prosperity
- Deficient safety cannot be compensated for by an abnormally high coupon rate
- The selection of all bonds for investment should be subject to rules of exclusion and to specific quantitative tests corresponding to those prescribed by statute to govern investments of saving banks.
Old Equity Investment (Common Stock) Theory - Threefold Principle
- A suitable and established dividend return
- A stable and adequate earnings record
- A satisfactory backing of tangible assets
P/E Ratio and Bond Interest Return
A PE ratio of 25 is equivilent to a 4% coupon ratio corporate bond. Both pay 4% on yield plus face value of the security when held to maturity/sold.
