What happens if g > ks?
If ks< g, get negative stock price, which is nonsense.
We can’t use model unless (1) ks> g and (2) g is expected to be constant forever. See slide #8-8.

Assume beta = 1.2, kRF = 6%, and kM = 11%. What is the required rate of
return on the firm’s stock?
ks = kRF + (kM - kRF)bFirm
= 6% + (11% - 6%) (1.2)= 12%.
Also, this is the cost of capital to the firm from issuing common Stk.
Use the SML to calculate ks:

If we have supernormal growth of 30% for 3 yrs, then a long-run constant
g = 10%, what is P0? k is still 12%.
Can no longer use constant growth model.
However, growth becomes constant after 3 years.

During nonconstant growth, D/P and capital gains yield are not constant, and capital gains yield is less than g.
After t = 3, g = constant = 10% = capital gains yield; k = 12%; so D/P = 12% - 10% = 2%.

If g = -6%, would anyone buy the stock? If so, at what price?
Firm still has earnings and still paysdividends, so P0 > 0:

What is the annual D/P and capital gains yield?
Capital gains yield = g = -6.0%,
Dividend yield = 12.0% - (-6.0%)= 18%.
D/P and cap. gains yield are constant,with high dividend yield (18%) offsettingnegative capital gains yield.

What is market equilibrium?
In equilibrium, stock prices are stable.There is no general tendency for people to buy versus to sell.
In equilibrium, expected returns mustequal required returns:
ks = D1/P0 + g = ks = kRF + (kM - kRF)b.^
8 - 22
How is equilibrium established?
If ks = + g > ks, then
P0 is “too low” (a bargain).
Buy orders > sell orders;
P0 bid up; D1/P0 falls until
D1/P0 + g = ks = ks.

What’s the Efficient Market Hypothesis?
EMH: Securities are normally in equilibrium and are “fairly priced.” One cannot “beat the market” except through good luck or better information.
8 - 25
1. Weak-form EMH:
Can’t profit by looking at past trends. A recent decline is no reason to think stocks will go up (or down) in the future. Evidence supports weak-form EMH, but “technical analysis” is still used.
8 - 26
2. Semistrong-form EMH:
All publicly available information is reflected in stock prices, so doesn’t pay to pore over annual reports looking for undervalued stocks. Largely true, but superior analysts can still profit by finding and using new information.
8 - 27
3. Strong-form EMH:All information, even inside information, is embedded in stock prices. Not true--insiders can gain by trading on the basis of insider information, but that’s illegal.
8 - 28
Markets are generally efficient because:
1. 15,000 or so trained analysts; MBAs, CFAs, Technical PhDs.
2. Work for firms like Merrill, Morgan, Prudential, which have much money.
3. Have similar access to data.
4. Thus, news is reflected in P0 almost instantaneously.

Preferred Stock
Hybrid security.Similar to bonds in that preferred
stockholders receive a fixed dividend which must be paid before dividends can be paid on common stock.
However, unlike interest payments on bonds, companies can omit dividend payments on preferred stock without fear of pushing the firm into bankruptcy.
