57
Q

A

share prices change instantly and without systematic biases
new information is unpredictable so price changes are a random walk
No opportunity for abnormal returns

58
Q

Explain a random walk

A

Todays change in share price, t, cannot be used to predict tomorrow’s
No correlation between share price changes in one period and another period

59

research to identify mispriced securities through stock patterns.
no evidence to suggest it works after transaction costs are accounted for

60
Q

Specialise in specific sectors
Do not exceed normal returns by a margin tat covers transaction costs.

61
Q

What are the three levels of EMH

A

Weak form
Semi strong
Strong

62
Q

What is weak form efficiency

A

This is where stock prices reflect all past information
Making abnormal returns by looking at historic data is not possible.

63
Q

What is semi-strong efficiency

A

Current share prices reflect past and all publicly available information
No advantage in analysing public information once released as already absorbed into stock price

64
Q

Strong efficency

A

Current share prices reflect all past data as well as public and private information
It is not possible to make abnormal returns

65
Q

Evidence testing weak-form

A

Serial correlation, determines the relationship between same variable over different periods, finds there is a very small relationship

66
Q

Evidence of semi-strong

A

Event studies, check if information is absorbed in one single jump. No evidence of abnormal returns
Manipulation of earnings- Depreciation rates applied to assets can be changed, semi strong should not be fooled by this. However collapse in ENCRON share price indicates a misleading.

67
Q

Evidence of strong form

A

markets are not strong form efficient, insider trading has been made illegal since 1980 in the UK. High ups in companies have to report amount and date of sale 90 days before completion of sale

69
Q

Book to market effect EMH

74
Q

Implication of EMH on Investors

A

Paying for investment research will not provide abnormal returns
Studying published accounts will not produce above average returns
no bargains in the stock market

Cost of paying fund managers

75
Q

Implication of EMH on Companies

A

Correct signal to managers
Share price fairly reflects its value and market expectations
Performance- shares provide feedback to managers
Cosmetic manipulation will not mislead the market
Ability for firms to raise finance is affected- it gives firms the required rate of return because the price is correct. As firms measure their value as income/cost of capital, by having the correct return it gives the correct value

76
Q

Implication of EMH on fundamental and technical analysts

A

It is not possible to make abnormal gains if markets are efficient. However due to these analysts searching for abnormal returns, it increases the speed in which prices absorb new information

77
Q

Implication of EMH on shareholders

A

EMH provides vital link between overall value of firm and market price of its shares, taken as measure of shareholder wealth

78

94
Q

How does irrational investors help the EMH

A

Irrational actions cancel each other out which leads to correct pricing

95
Q

Arbitrage definition

A

Act of exploiting price differences on the same or similar securities by simultaneously selling overpriced and buying under priced security

96
Q

Limits to arbitrage

A

Fundamental risk
Noise trader risk
Implementation costs
Law of one price

97
Q

Why does fundamental risk occur

A

It exists because of the potential for rational revaluation as new info arrives

98
Q

Explain what fundamental risk is

A

If an arbitrageur thinks a particular stock is over valued, they will short-sell it.
New info might arrive which causes the price to rise further
Price might converge to intrinsic value but may nit be within traders investment horizon

99
Q

VW short squeeze

A

In 2008 a number of hedge funds sold vow shares short thinking the price will lower as have gloomy outlook
Porsche gained control of 74% of shares
Price went from 200-1000 euros and there was not enough stock for hedge funds to buy so lost lots of money

100
Q

Noise trader risk

A

Opinion on value based on misinformation
Wring prices may become even more wrong in the short run
It is a systematic risk
Arbitrageur may have to liquidate early and sustain steep losses

101
Q

Implementation costs

A

Short selling is:
Expensive- cost of correcting mispricing may exceed potential gain
Difficult- lack of availability
Legal factor- pensions and mutual funds have strict limits
All limit ability of arbitrage activity to force prices to be fair

102
Q

Law of one price

A

Identical assists should have identical prices

103
Q

Law of one price example

A

Royal Dutch and Shell - 60-40 split so Dutch should be 1.5 times more expensive . In 1993 Dutch was more than 1.5 times, buy shell and short sell royal Dutch

104
Q

What is a bubble

A

Observed prices soar far higher than fundamentals and rational analysis would suggest, easy to identify once over but not whilst in one

105
Q

BAPM

A

Assumes beta isn’t a sufficient measure of risk and social status should be involved

106
Q

Argument against behavioural asset pricing

A

Easy to reverse engineer an explanation to an anomaly
Extent to which limited rationality affects asset pricing remains controversial

119
Q

Bounds on option prices

A

C<S> S-Xe^-r(T-t)
Explained using no arbitrage principle</S>

120
Q

Assumptions of black-Scholes model

A

No dividend or interest during lifetime
European option
Fixed risk free rate
No taxes or transaction costs
Prices of underlying asset are log normally distributed

121
Q

How do the variables increasing affect option value

A

Price volatility leads to increase in option value
Time to expiration leads to increase
Exercise price leads to a decrease
Current stock price and interest rates lead to an increase

122
Q

Why does it make sense to sell option before expiration

A

Before expiration it has some time value, holder should be able to get more than S-X in the market place

123
Q

Practical issues with Black-Scholes

A

Variance and risk free rate assumed constant but these vary
Large prices were more frequently observed in real world than implied in model
Lognormal dust is a questionable assumption

124
Q

How does time to expiration affect call option price math based

A

For the mathematical reasonings as the second part of the equation is -Xe^-r(T-t), as T-t gets larger , the equation gets smaller , this leads to the whole equation getting larger.

125
Q

Time to expiration affect price, economic based

A

As we are further from the expiration time, this means there is a larger time value for the share, as there is longer for the underlying asset to change price, there is a higher chance that the price will go further above the strike price.

126
Q

How does share price affect call option value

A

If the share price is higher, that means at expiration we have a larger S-X which means more profit will be made, as the holder of the option will be making more money, the price of the option increases.

127
Q

How does interest rates affect call option value

A
  1. As r increases we get that e^-r get smaller and as we subtract this away from the first part of the equation, it means we get a larger value for the option.
  2. As well as this, if R increases, as the option is priced less than the share as we have no arbitrage in the model, we can invest the left over money we have saved by buying the option and invest that in the risk free rate meaning it generates more money.
128
Q

Strike price effect call option value

A

If the strike price increases with everything else staying constant. This means that S-X will be smaller and less profit being made which decreases the price of the option.

129
Q
A
130
Q

How dos volatility affect the price of call option

A

If a stock is more volatile, this means that there is an increased chance that the price of the underlying asset is above the strike price than a less volatile stock that doesn’t move as much. Therefore, as there is a higher chance that the option will be in-the-money, the value of it is higher.

Q
A
