Q

efficient frontier

A

portfolios with the greatest level of return for each level of risk

The efficient frontier outlines the set of portfolios that gives investors the highest return for a given level of risk or the lowest risk for a given level of return. Therefore, if a portfolio is not on the efficient frontier, there must be a portfolio that has lower risk for the same return. Equivalently, there must be a portfolio that produces a higher return for the same risk.

Q

A portfolio to the right of the market portfolio on the CML is:

A

an inefficient portfolio.

A portfolio to the right of a portfolio on the CML has more risk than the market portfolio. Investors seeking to take on more risk will borrow at the risk-free rate to purchase more of the market portfolio

25
Availability bias
putting undue emphasis on on information that is readily available/easy to recall e.g. picking a manager you know
26
loss-aversion bias
feeling more pain from losses than joy with equal gains
27
overconfidence bias
overestimating own abilities to make decisions - can also lead to illusion of knowledge bias and self-attribution bias
28
self-control bias
occurs when individuals lack self-discipline and favour short-term sacrifices to meet long-term goals.
29
status quo bias
occurs when comfort with an existing situation causes a resistance to change
30
Endowment bias
occurs when an asset is felt to be special and more valuable because it is already owned
31
Regret-aversion bias
occurs when investors do not take action, due to fear of being wrong e.g. herding behaviour
32
Delta
sensitivity of derivative values to the price of underlying asset
33
Gamma
sensitivity of delta to the price of the underlying asset
34
Vega
sensitivity of derivative values to the volatility of the price of the underlying asset
35
Rho
sensitivity of derivative values to changes in the risk-free rate
36
Tail risk
the uncertainty about the probability of extreme (negative outcomes) e.g. downside risk, VaR
37
Value-at-Risk (VaR)
minimum loss over period with a specific probability | e.g. 1-month VAR of $1m with 5% probability = an expected loss of at least $1m in 5% of months
38
Conditional VaR
expected value of loss, given that loss exceeds a specific amount. It is calculated as the probability-weighted average loss for all losses over a certain amount
39
self-insurance
where a company bear the losses of a particular risk factor
40
risk transfer
when another party takes on a specific risk
41
surety bond
where an insurance company agrees to make a payment if a third-party fails to perform its duty to an organisation.
42
fidelity bonds
where an insurance company agrees to make a payment in the event of employee theft/misconduct.
43
risk shifting
distributing risks via the use of derivative contracts
44
Risk management process / framework
The risk management process should identify an organization's risk tolerance, identify the risks it faces, and monitor or address these risks. The goal is not to minimize or eliminate risks. This includes the procedures, analytical tools, and infrastructure to conduct the risk governance process
45
Risk governance should most appropriately be addressed within an organization at:
the enterprise level. Risk governance should be approached from an enterprise view, with senior management determining risk tolerance and a risk management strategy on an organization-wide level
46
Risk budgeting
Selecting assets or securities by their risk characteristics up to the maximum allowable amount of risk. The maximum amount of risk to be taken is established through risk governance.
47
Sources of financial risk
- market risk - credit risk - liquidity risk
48
Technical analysis
Driven only by share price and volume of trading data to project price. 3 key principles: 1. Market prices reflect all known info 2. Market prices exhibit trends and countertrends that persist. 3. Patterns and and cycles repeat themselves in predictable ways.
49
A market that is 'uptrend' in prices
demand is increasing relative to supply (prices consistently rising) (+1 gradient)
50
A market that is 'downtrend' in prices
supply is increasing relative to demand (prices consistently declining) (-1 gradient)
51
A market that is in 'consolidation'
there is neither an uptrend or downtrend apparent.
52
support level
Price where buying pressure limits a downtrend (the lowest/bottom price of a stock)
53
resistance level
price where selling pressure limits and uptrend (the highest/top price of a stock)`
54
'change in polarity'
breached resistance levels --> support levels and breached support levels --> resistance levels
55
Technical indicators
- Price-based indicators e.g. moving averages, Bollinger bands - Momentum oscillators e.g. ROC, RSI, MACD - Sentiment (non-price) indicators e.g. put/call, VIX, margin debt
56
momentum oscillator
indicators based on market prices but scaled so they 'oscillate around a given value.
57
Convergence
When the oscillator shows the same pattern as prices
58
Divergence
When the oscillator shows a different pattern as prices
59
Rate of Change (ROC) oscillator
100x the difference between the latest closing price and the closing price n periods earlier. Oscillates around 0
60
Relative Strength Index (RSI)
based on the ratio of total price increases to total price decreases over n number of periods. The ratio is then scaled to oscillate between 0-100, with high values indicating an overbought market and visa versa.
61
Moving Average Convergence/Divergence (MACD)
MACD oscillators are drawn using smoothed moving averages - placing greater weight on recent observations. The MACD line is the difference between two exponentially smoothed moving averages of the price. - Used to identify convergence/divergence with the price trend.
62
Stochastic oscillator
Calculated from the latest closing price and highest/lowest prices reached in a recent period. - the "%K" line is the difference between the latest price and the recent low as a percentage of the difference between the recent high and low. The "%D" line is a 3-period average of the %K line.
63
put / call ratio
put volume / call volume p/c ↑ negative outlook for price of asset
64
``` Volatility Index (VIX) (calculated by the Chicago Board Options Exchange) ```
- measures the volatility of options on the S&P 500 stock index. VIX ↑ investors fear a decline in the stock market
65
Margin debt
total margin debt ↑, aggressive buying by bullish margin investors.
66
intermarket analysis
an analysis of the relationships between market values of major asset classes, such as stocks, bonds, commodities and currencies.
67
Relative strength charts
used to determine which asset classes are outperforming
68
the 'Buy signal' - when using moving average
'golden cross': a shorter-term average above a longer-term average
69
the 'Sell signal' - when using moving average
'dead cross': a shorter-term average below a longer-term average
70
'Big Data'
- all potentially useful data (traditional + alternative data). - volume, velocity and variety
71
Data science and processing methods
How we extract information - capture - curation - storage - search - transfer
72
supervised learning
a machine learning technique in which a machine is given labelled input and output data and then models the output data based on the input data
73
unsupervised learning
a machine is given input data in which to identify patterns and relationships, but no output data to model
74
Deep learning
a technique to identify patterns of increasing complexity, and may use supervised or unsupervised learning.
75
Overfitting
A model that is overfit (too complex) will tend to identify spurious relationships in the data. Labelling of input data is related to the use of supervised or unsupervised machine learning techniques.
76
Underfitting
Underfitting describes a machine learning model that is not complex enough to describe the data it is meant to analyse. An underfit model treats true parameters as noise and fails to identify the actual patterns and relationships.
77
Tokenization
maintaining ownership records for physical assets on a distributed ledger.
