Accounting defeasance
Also called in-substance defeasance, defeasance is a provision in a contract that voids a bond or loan on a balance sheet when the borrower sets aside cash or bonds sufficient enough to service the debt.
(defeasance: the action or process of rendering something null and void)
- -> In-substance defeasance occurs when a firm irrevocably deposits cash or other assets Into a trust for the sole purpose of making principal and interest payments on debt as the payments become due.
Accumulation phase
Phase where the government predominantly contributes to a sovereign wealth pension reserve fund
Active management for a stable upward sloping yield curve
a changing yield curve?
Active management for a stable upward sloping yield curve
- buy and hold: extend duration to get higher yield
- roll down the yield curve: portfolio weighting highest for securities at the long end of the steepest yield curve segments, maximize gains on securities from declines in yield as time passes
- sell convexity to increase yield(higher yield bonds have less convexity)
- carry trade: borrow at a lower rate to purchase securities with higher rates
Active management for a changing yield curve
- increase portfolio duration if rates are expected to decrease, decrease duration if rates are expected to increase
- increase portfolio exposure to key rate durations where relative decreases in key rates are expected. Decrease portfolio exposure to key rate duration where relative increases in key rates are expected (The key rate is the interest rate at which banks can borrow when they fall short of their required reserves. )
- long option positions are a more effective way to add convexity. Short option positions reduce convexity.
Active return
–> how to calculate it
The portfolio’s return in excess of the return on the portfolio’s benchmark.
Exp. Active return =
info. coefficient x square root of breadth x s.d. of active return x transfer coefficient
- info coef: The information coefficient shows how closely the analyst’s financial forecasts match actual financial results. The IC can range from 1.0 to -1.0, with -1 indicating the analyst’s forecasts bear no relation to the actual results, and 1 indicating that the analyst’s forecasts perfectly matched actual results.
- Breadth: The number of truly independent decisions made each year.
- -> if a manager selects ten stocks every month, his breadth is 10 x 12 = 120. If a manager makes a selection every quarter, his breadth is 4
- s.d. of active return: the difference between the benchmark and the actual return aka the active risk
- transfer coef: defined as the correlation between the risk-adjusted alphas and active weights. The TC is an objective measure of how much of the alphas’ information is transferred into a portfolio and is a measure of portfolio construction efficiency
Active risk
–> how to calculate
Active risk aka tracking error is a type of risk that a fund or managed portfolio creates as it attempts to beat the returns of the benchmark against which it is compared. Active risk is the difference between the managed portfolio’s return less the benchmark return over some time period. Actively-managed funds will have risk characteristics that vary from their benchmark. Generally, passively-managed funds seek to have limited or no active risk in comparison to the benchmark they seek to replicate.
–> a pm can completely control active share (weightings) but not active risk. If a manager switches out a pair trade with a less correlated pair trade, the active risk will increase (i.e. Fund 3 held active positions in two automobile stocks—one was overweight by 1 percentage point (pp), and the other was underweight by 1pp. Fund 3 trades back to benchmark weights on those two stocks and then selects two different stocks, one energy stock and one financial stock. Fund 3 overweights the energy stock by 1pp and underweighted the financial stock by 1pp increasing the funds active risk but leaving active share unchanged)
active risk =
square root of [ (year 1 port return - year 1 benchmark return)^2 + (year 2 port return - year 2 benchmark return)^2… etc / (n-1)]
–> The level of active risk will rise with an increase in idiosyncratic (individual) volatility.
I.e you could benchmark to a sector and neutralize that factor exposure (lowering the active share) but take concentrated bets within a factor which increases your active risk
–> The active risk attributed to Active Share will be smaller in more diversified portfolios.
–> combining a fund with high covariance to a portfolio will lower active risk of the overall portfolio (high covariance = lower the tracking error)
–> All portfolios have risk, but systematic and residual risk are out of the hands of a portfolio manager, while active risk directly arises from active management itself. (sector bets are an example of active risk)
–> In a single-factor model, if the factor exposure is neutralized, the active risk will be entirely attributable to the Active Share—a consequence of the manager deviating from benchmark weights.
Active risk budgeting
Risk budgeting addresses the question of which types of risks to take and how much of each to take. Active risk budgeting addresses the question of how much benchmark-relative risk an investor is willing to take. At the level of the overall asset allocation, active risk can be defined relative to the strategic asset allocation benchmark. At the level of individual asset classes, active risk can be defined relative to the benchmark proxy.
Active share
–> equation to find it?
A measure, ranging from 0% to 100%, of how similar a portfolio is to its benchmark. The measure is based on the differences in a portfolio’s holdings and weights relative to its benchmark’s holdings and their weights. A manager who precisely replicates the benchmark will have an active share of zero; a manager with no holdings in common with the benchmark will have an active share of one.
active share = .5 (sum of all (absolute value of weight of security i in the portfolio - weight in benchmark))
- -> High Active Share indicates that a manager’s holdings differ substantially from the benchmark, and low active risk indicates low idiosyncratic risk resulting from diversification: This combination indicates that the manager most likely follows a diversified stock picking strategy.
- -> Active share changes only if the total of the absolute values of the portfolio’s active weights changes. i.e. for two trades, if both the initial position and the new position involved two stocks such that one was 1pp underweighted and the other was 1pp over weighted. Although the active weights of particular securities did change between the initial position and the new position, the total absolute active weights did not change. Therefore, the portfolio’s active share would not change
Activist short selling
A hedge fund strategy in which the manager takes a short position in a given security and then publicly presents his/her research backing the short thesis.
what are the five conclusions of the adaptive markets hypothesis?
(AMH) A hypothesis that applies principles of evolution—such as competition, adaptation, and natural selection—to financial markets in an attempt to reconcile efficient market theories (EMH assumes that market prices reflect all available information) with behavioral alternatives.
–> The AMH theory assumes that successful investors apply heuristics or mental rules of thumb until they no longer work
The AMH leads to these five conclusions:
- The relationship between risk and return is not perfectly stable. It changes over time as the competitive environment changes.
- Active management of investments can find opportunities to exploit inefficiencies from time to time
- Adaption and innovation are key to survival
- Survival is the only objective that matters
- No strategy will work all the time
Agency trade
A trade in which the broker is engaged to find the other side of the trade, acting as an agent. In doing so, the broker does not assume any risk for the trade.
Alpha decay
In a trading context, alpha decay is the erosion or deterioration in short term alpha after the investment decision has been made.
–> ALPHA DECAY is the phenomenon whereby a particular investment methodology deteriorates in performance over time. Initially well suited to the original market conditions at the time of inception. Trades are more valuable when under-discovered, and as the trade becomes crowded, the potential alpha decays
Alternative trading systems
An alternative trading system (ATS) is one that is not regulated as an exchange but is a venue to match the buy and sell orders of its subscribers. (ATS brings together buyers and sellers to find transaction counterparties outside of a regulated exchange - i.e. dark pools.)
- -> Also called multilateral trading facilities (MTF).
- -> Regardless of the trading venue, transactions and quantities are always reported.
- -> Dark pools provide anonymity because no pre-trade transparency exists. Exchanges are known as lit markets (as opposed to dark markets) because they provide pre-trade transparency—namely, limit orders that reflect trader intentions for trade side (buy or sell), price, and size. However, with a dark pool, there is less certainty of execution as compared to an exchange.
Anchoring and adjustment (anchoring bias)
–> how to overcome this bias?
An information-processing bias in which the use of a psychological heuristic influences the way people estimate probabilities - i.e. when a person starts out with an initial idea and adjusts their beliefs based on this starting point.
–> fixating on a target number once an investor has it in mind
–>The anchoring bias is the tendency of the mind to give disproportionate weight to the first information it receives on a topic: initial impressions, estimates, or data, anchor subsequent thoughts and judgments.
–> Despite setbacks and new information, an investor may not appropriately adjust his view due to perceiving new information through a warped lens and thus, the decision making may deviate from rational reasoning.
–> To overcome anchoring bias, the manager should consciously ask questions that may reveal an anchoring and adjustment bias: “Am I holding on to this stock based on rational analysis, or am I trying to attain a price that I am anchored to, such as the purchase price or a high water mark?”
Ex: an analyst should look at the basis for his decision to hold ABC to determine if it is anchored to a price target (a new 52-week high) or based on an objective, rational view of the company’s fundamentals. Gerber should have periodically reviewed his decision-making process to determine if his analysis of ABC’s prospects was appropriate, focusing more on the company’s fundamentals rather than the price target.
Anomalies
Apparent deviations from market efficiency.
Arithmetic attribution
An attribution approach which explains the arithmetic difference between the portfolio return and its benchmark return. The single-period attribution effects sum to the uity eturn, however, when combining multiple periods, the sub-period attribution effects will not sum to the excess return.
Arrival price
In a trading context, the arrival price is the security price at the time the order was released to the market for execution.
Aspirational risk bucket
–> Three tools for addressing a concentrated position in a publicly traded common stock
In goal-based portfolio planning, that part of wealth allocated to investments that have the potential to increase a client’s wealth substantially.
- -> includes assets such as a privately owned business, commercial and investment real estate, and concentrated stock positions.
- -> Three tools for addressing a concentrated position in a publicly traded common stock include outright sale, monetization, and hedging.
Asset location
The type of account an asset is held within, e.g., taxable or tax deferred.
Focus of asset-only asset allocation
With respect to asset allocation, an approach that focuses directly on the characteristics of the assets without explicitly modeling the liabilities.
–> focuses on asset return and standard deviation
Authorized participants
An authorized participant is an organization that has the right to create and redeem shares of an exchange traded fund (ETF).
–> Broker/dealers who enter into an agreement with the distributor of the fund.
Availability bias
A cognitive error where people let predicted future probabilities be impacted by memorable past events (information processing bias - product of faulty reasoning and analysis)
- -> the human tendency to think that examples of things that come readily to mind are more representative than is actually the case
- -> As a result of availability bias, investors may choose an investment based on advertising rather than on a thorough analysis of the options.
- -> Investors who exhibit availability bias may limit their investment opportunity set, may choose an investment without doing a thorough analysis of the stock, may fail to diversify, and may not achieve an appropriate asset allocation.
- -> An investor could overcome this bias by developing an appropriate investment policy strategy, with a focus on appropriate goals (short- and long-term), and having a disciplined approach to investment decision making. An investment policy statement would help provide discipline and would alert the investor that he really has only considered investments that he is familiar with. Further, an investor should consider the asset allocation within the portfolio.
Back-fill bias
The distortion in index or peer group data which results when returns are reported to a database only after they are known to be good returns.
Barbell portfolio and when is this strategy useful?
–> what sort of portfolio works best under a flattening yield curve?
The barbell strategy is used to take advantage of the best aspects of short-term and long-term bonds. In this strategy only very short-term and extremely long-term bonds are purchased. Longer dated bonds typically offer higher interest yields, while short-term bonds provide more flexibility.
The short-term bonds give an investor the liquidity to adjust potential investments every few months or years. If interest rates start to rise, the shorter maturities allow an investor to reinvest principal in bonds that will realize higher returns than if that money was tied up in a long-term bond.
The long-term bonds give an investor a steady flow of higher-yield income over the term of the bond. However, by not having all of your capital in long-term bonds, this limits the downside effects if interest rates were to rise in that bond period.
- -> Under a flattening yield curve, a barbell portfolio will outperform bullet portfolios or laddered portfolios
- -> if the curve steepens, a bullet position will outperform the barbell portfolio. In a steepening, the short- and intermediate-term bonds will maintain/gain value from flat/lower rates while long-maturity bonds will lose value from rising rates
- -> The higher-convexity barbell portfolio will likely outperform the bullet portfolio if there is an instantaneous downward parallel shift in the yield curve because of the barbell portfolio’s greater sensitivity to the expected decline in yields. Portfolios with higher convexity are most often characterized by lower yields (they are more exposed to int rate movements vs CP credit). Investors will be willing to pay for increased convexity when they expect yields to change by more than enough to cover the give-up in yield.
–>The optimal time for bond investors to implement the barbell strategy is when there are large gaps between short- and long-term bond yields.
Base Currency
With respect to a foreign exchange quotation of the price of one unit of a currency, the currency referred to in “one unit of a currency.”
- -> i.e. CAD/USD - CAD is the base and USD is the quote currency
- -> If U.S. dollars (USD) are used to buy GBP, the exchange rate is for the GBP/USD pair.
- -> you buy the base at the bid, sell the base at the ask
