From Modern Security Analysis:
In GADCP, there is no emphasis on estimating future flows. Rather it is recognized that growth in common stock prices can come, and frequently does come, from sources other than corporate operations. Growth can come from judicious acquisitions (Capital Southwest Common); creating unrealized, and unrecorded, appreciation in asset values (Forest City Enterprise Common, Hopewell Holdings Ordinary); creating hidden assets in the form of increases in adjusted book value (Carlyle Group); having companies taken over by others at premium prices (Brookfield Asset Management); and possibly participating in corporate restructurings (Nabors Industries).
In forecasting future flows of revenues, earnings, or cash flows, no exclusivity in making these forecasts is given to the past earnings record under a GADCP analysis. It is recognized under GADCP that the quality of resources in a business and the quantity of resources in a business tend to be equally important, and for some companies are more important than the past record in making reasonably accurate forecasts of future flows. This is simply giving recognition to ROE and ROA as part of the forecasting process with Equity and Assets being balance sheet items.
In GADCP, though, there is strong recognition given to the fact that most forecasts, no matter what techniques are used to make them, are going to prove to have been inaccurate. It is just too difficult to properly put into forecasts factors such as competitive forces, technological innovations, inexperienced managements, business cycles, access to capital markets and acts of God. Knowing of the inherent unreliability of its forecasts, we restrict our common stock investments to issues that enjoy very high-quality resources where we can acquire its interests at prices that represent a meaningful discount from the estimated quantity of resources that exist in a business.
GADCP is inherently long-term conscious. Indeed, securities markets tend to be efficient enough that a GADCP investor is unlikely to find issues at attractive prices unless the near-term outlook is poor to clouded.
Industry outlooks are as important for GADCP as they are for GARP. However, under GADCP, industry outlooks are based on independent analysis rather than conformity with a general consensus.
