One approach to firm valuation is to focus on the firm's book value, either as it appears on the balance sheet or as adjusted to reflect current replacement cost of assets or liquidation value.
Another approach is to focus on the present value of expected future dividends.

Dividend Discount Models: General Model
The dividend discount model holds that the price of a share of stock
should equal the present value of all future dividends per share,
discounted at an interest rate commensurate with the risk of the stock

Constant Growth Model
The constant-growth version of the DDM asserts that if
dividends are expected to grow at a constant rate forever,
the intrinsic value of the stock is determined by the formula
π = constant perpetual growth rate

Constant Growth Model
This version of the DDM is simplistic in its assumption of a constant value of π. There are more-sophisticated multistage versions of the model for more-complex environments.
When the constant-growth assumption is reasonably satisfied and the stock is selling for its intrinsic value, the formula can be inverted to infer the market capitalization rate for the stock:

Constant Growth Model
The constant growth dividend discount model is best suited for firms that are expected to exhibit stable growth rates over the foreseeable future.
In reality, however, firms progress through lifecycles. In early years, attractive investment opportunities are ample and the firm responds with high plowback ratios and rapid dividend growth.
Eventually, however, growth rates level off to more sustainable values.
Three-stage growth models are well-suited to such a pattern. These models allow for an initial period of rapid growth, a final period of steady dividend growth, and a middle, or transition, period in which the dividend growth rate declines from its initial high rate to the lower sustainable rate.

The expected growth rate of earnings is related both to the firm's expected profitability and to its dividend policy. The relationship can be expressed as
π = growth rate in dividends
π ππΈ = Return on Equity for the firm
π = plowback or retention ratio = 1 β π
π = dividend payout ratio

Partitioning Value: Example
Stock market analysts devote considerable attention to a company's price-to-earnings ratio.
The π/πΈ ratio is a useful measure of the market's assessment of the firm's growth opportunities.
Firms with no growth opportunities should have a π/πΈ ratio that is just the reciprocal of the capitalization rate, k.
As growth opportunities become a progressively more important component of the total value of the firm, the π/πΈ ratio will increase.

Pitfalls in P/E Analysis
Many analysts form their estimate of a stock's value by
multiplying their forecast of next year's πΈππ by a π/πΈ multiple
derived from some empirical rule.
This rule can be consistent with some version of the π·π·π,
although often it is not.
Often people use average π/πΈ ratio using past data, which
ignores the growth opportunity of the firm.
Use of accounting earnings also has its problems, e.g.,
- Historical costs in depreciation and inventory valuation: during high
inflation period, the use of historical cost would underestimate cost thus
overestimate earnings and underestimate π/πΈ ratio.
Inflation and Equity Valuation
Inflation has an impact on real stock returns.
Research shows that real rates of return are lower with
higher rates of inflation.
Remember Fisher effect?
π = π β π (approximate)
Empirical research shows that inflation has an
adverse effect on equity values.
Inflation and Equity Valuation
One reason is the lower real after-tax earnings and dividends attributable to inflation-induced distortions in the tax system.
Often govt. tries to implement contractionary fiscal policy i.e. raise taxes to reduce inflationary pressure.
