Q

when is returns based attribution appropriate

A

when the underlying portfolio holding information is not available with sufficient frequency at the required level of detail

hedge funds, for example, because it can be difficult to obtain the underlying holdings

easiest to implement, but least accurate

Q

Yield Curve Decomposition

A
  • (Duration based)
  • Can be top-down approach or bottom up from security level, estimating the return of securities, sector buckets, or YTM buckets

%Total return = % Income return + % Price return

33
Sharpe ratio
The ratio of mean excess return to standard deviation (excess return) (Return - risk free rate) / standard deviation
34

Annualized alpha divided by the annualized residual risk, which are both computed from a factor regression alpha/standard error of regression
38
Sortino Ratio
modification of sharpe ratio that penalizes only those returns that are lower than a user-specified return (return - user-specified return) / risk
39
Drawdown
a percentage peak-to-trough reduction in net asset value the loss in vale incurred in any continuous period of negative returns
40
Capture ratio
Measures the manager's participation in up and down markets upside capture / downside capture Upside capture greater than 100% signifies outperformance (convex return profile) downside capture less than 100% signifies outperformance (concave return profile)

A top-down analysis that involves estimating the sensitivities of a portfolio to security market indexes
49
Holdings-based style analysis (HBSA)
A bottom-up style analysis that estimates the risk exposures from the actual securities held in the portfolio at a point in time
50
Drawdown duration
The total time from the start of the drawdown until the cumulative drawdown recovers to zero i.e. drawdown duration of 4 months means portfolio lost money and recovered in 4 months
51
Active share
a measure of how similar a portfolio is to its benchmark a manager who precisely replicates the benchmark will have an active share of zero a manger with no holdings in common with the benchmark will have an active share of one
52
High tracking risk + low active share
sector rotation
53
High tracking risk + high active share
concentrated stock pickers
54
Low tracking risk + low active share
closet indexer
55
Low tracking risk + high active share
Diversified stock pickers
56
Risk premiums
extra returns expected by investors for bearing some specified risk
57
Two categories of market inefficiencies
1) Behavior 2) Structural
58
Behavior inefficiencies
Perceived mispricings created by the actions of other market participants, usually associated with biases, such as trend following or loss aversion temporary, lasting long enough for the manager to identify and exploit them before the market price and perceiving intrinsic value converge
59
Structural inefficiencies
Perceiving mispricings created by external or internal rules and regulations can be long lived and assume a continuation of the rules and regulations rather than a convergence
60
Key person risk
the risk that results from over-reliance on an individual or individuals whose departure would negatively affect and investment manager
61
Groupthink
Behavioral bias that occurs when a team minimizes conflict and dissent in reaching and maintaining a consensus
62
Authority bias
Behavioral bias which involves groups deferring to a group member that is a subject matter expert or in a position of authority
63
Aversion of complexity
A behavior bias in which disproportionate attention is given to trivial issues at the expense of important but harder-to-grasp or contested topics
64
3 keys of information to exploiting inefficiencies in the market
1) Unique 2) Timely 3) Interpreted differently
65
4 Elements of the investment decision-making process
1) Signal creation 2) Signal capture 3) Portfolio construction 4) Portfolio monitoring
66
what conclusions does performance attribution draw regarding the quality of a portfolio manager's investment decisions
none
67
For top down investment approach, what is the most appropriate risk attribution approach
attribute tracking risk to allocation and selection decisions relative to the benchmark
68
target semi-standard deviation (target semideviation)
denominator of the sortino ratio (average portfolio return - MAR) / sortino ratio MAR = minimum acceptable return Sq(Sum of all (deviations below MAR^2) / n-1)
69
what capture ratio indicates convex return profile
capture ratio greater than 1
70
what capture ratio indicates concave return profile
capture ratio less than 1
71
Why can holdings-based attribution generate a residual term between the portfolio performance and benchmark performance
1) Timing of transactions 2) Price differences 3) Reinvestment of cash flows 4) Market movements in other words, not by the the fund manager's actions
72
two common approaches for equity attribution
1) brinson - fachler 2) factor-based attribution
73
Brinson model
widely used performance attribution model to understand the sources of a portfolio's returns relative to a benchmark; three main components 1) Allocation effect: impact of pm's decisions to allocate assets differently from the benchmark 2) Selection effect: pm's ability to select securities within each sector 3) Interaction effect: combined impact of allocation and selection effect, which can sometimes offset each other
74
Allocation effect
(portfolio weight - benchmark weight) * (benchmark return for that category - total benchmark return)
75
Selection + Interaction effct
benchmark weight * (portfolio return - benchmark return) + (portfolio weight - benchmark weight) * (portfolio return - benchmark return)
76
return due to manager style
S = B - M S = return due to manager style B = return on the benchmark portfolio M = return on the appropriate market index
77
Performance appraisal
indicates whether the portfolio's performance was achieved through manager skill or through luck
78
Qualitative consideration most associated with determining whether investment manager selection will result in superior repeatable performance
investment process
79
when is style analysis most useful
when applied to strategies that hold publicly traded securities where pricing is frequent
80
4 main advantages of SMA
1) Ownership 2) customization 3) tax efficiency 4) Transparency
81
3 main disadvantages of SMA
1) Cost 2) Tracking risk 3) Investor behavior
82
pooled investment
fund where multiple investors combine money to invest together ETFS and mutual funds
83
components of qualitative analysis
1) Investment due diligence 2) Operational due diligence
84
investment due diligence
Which manager "best fits the portfolio need? 1) Philosophy 2) Process 3) People 4) Portfolio
85
Operational due diligence
Is the manager's track record accurate, and does it fully reflect risks? 1) Process and procedure 2) Firm 3) Investment vehicle 4) Terms 5) Monitoring
86
aspects of quantitative analysis
What has been the manager's return distribution? 1) Attribution and appraisal: has the manager displayed skill? 2) Capture ratio: how does the manager perform in "up" markets versus "down" markets? 3) Drawdown: does the return distribution exhibit large drawdowns?
87
Which error type is an error of mistaken rejection
Type I
88
Which error type is an error of failing to detect a true relationship
Type II
89
Which error type is more easily measured
Type I
90
Which error type is linked to the compensation of the decision maker
Type I
91
which style analysis is subject to window dressing
HSBA because it is a snapshot of the portfolio at a single point of time
92
which style analysis is comparable across managers and to itself across time
returns based because it is able to identify the important drivers of return and the relevant risk factors for the period analyzed, even for complicated strategies
93
style analysis top down vs bottom up approach
bottom up - holdings based top down - returns based
94
soft lock
provision that allows investors to redeem their shares during the lock-up period, but with certain restrictions or penalties
95
which fee structure decreases the volatility of a portfolio's net returns
incentive fees because they are charged as a % of returns, reducing net gains in positive months and net losses in negative months
