Quant Flashcards
Holding period return
Leveraged return
Gordon growth model
Implied yield
What is Kurtosis
Degree at which distribution is peaked
What does platykuratic mean
Wider less steep centre of distribution (think platypus’ beak)
What does excess kurtosis mean
More or less kurtosis than a normal distribution
If a distribution is positive what does that mean
Means it is right tailed
What does it mean if a distribution is negative
It is left tailed
How to work out correlation
Covariance/sDxSd
Relative dispersion
What is shortfall risk and what formula would you use to help you?
Probability that a portfolios return or value will be below a specified target return or value over a specified period. Use Roy’s safety criterion
What does Roy’s safety criterion state?
States that the optimal portfolio minimises the probability that the return of the portfolio will fall below some minimum acceptable threshold level
What skew does a log normal distribution have?
Positive
What is a log normal distribution useful for
Modelling asset prices if we think of an assets future price as the result of a continuously compounded return on its current price
What is a Monte Carlo simulation
Type of sample performed by making assumptions about the distributions of prices or risk factors using large number of generated values to generate a distribution of possible outcomes
What is bootstrapping
Draw repeated samples from the full data set replacing the observations each time
What is judgemental sampling?
Refers to samples for which each observation is selected from a larger data set based on judgement
What is stratfied random sampling
Separates a population but assumes that each subset
What is standard error of sample mean?
What is jackknife method
Alternative way to calculate standard error of sample mean. One observation is removed
What is central limit theorem
States that sampling distribution of the mean approaches a normal probability distribution with mean mu and a variance equal to SD squared divided by n as sample gets larger than 30
What is sampling error
Difference between the observed value of a statistic and the quantity it is intended to estimate
What is a null hypothesis
Hypothesis you want to reject (H0)
