Theories of Finance

Financial theories and models play a crucial role in understanding how markets operate and how companies can efficiently manage their resources and risks. Central to these theories is the concept of market efficiency, which posits that asset prices reflect all available information, with varying degrees of efficiency characterized as weak, semi-strong, and strong forms.

If a change in dividend policy is to have no effect on share value this change must cause an equal but opposite change in the expected capital gain component of total return

Efficient: means that todays prices incorporate all the information which is currently available to potential buyers and sellers

The measure to determine how sensitive individual shares are to the return of the total stock market (BETA)

Ke= Rf + Beta (Rm-Rf)

Market Risk relates to the market as a whole. The economic cycle which would impact all companies. Market risk cannot be diversified

P= D1 / (Ke - g)

Unique risk relates to the particular company. It would include the risk of product failures, product market changes, etc

The efficient Market hypothesis

1. The weak form of the efficient market hypothesis is that all historical price information is incorporated into current share prices
2. The Semi-strong form argues that all published financial information is already included in the current share price

3. The strong form of efficient markets says that current prices reflect all the available information could be known

The Cost of Capital

Debt
Kd= i(1-t)
Equity
Two ways of calculate the cost of equity:

Capital Asset Pricing Model (CAPM): Risk in a financial instrument is defined as the volatility in the expected return - This high volatility in expected translates into a high required return

Simple Dividend Growth Model: Shareholders achieve their return through a mixture of dividends and capital gain

Discounted Cash Flows
