EVERYTHING Flashcards
portfolio management
the professional management of securities/assets (real or financial to meet pre-specified investment objectives set by investors
real assets
land,building,machines and knowledge of service
financial assets
stocks, bonds, derivatives or any combination of these assets. no more than thin sheets of paper
pre-specified investment objectives
based on an investor’s need and risk tolerance - achievable and for a fixed time horizon
where are securities traded?
- equity markets
- fixed income markets
equity markets
exchanges: TSE, NYSE, NASDAQ, american stock exchange
market indexes
hypothetical portfolio that represents financial markets (or a particular sector)
Canada: S&P 500/TSX composite index (market-value index)
US: S&P500, dow jones 30 industrial average (DJIA)
fixed-income markets
Canada and US
exchanges: no exchanges but over-the-counter (OTC)
barclay’s capital bond index: (corporate&gov bonds, MBS, treasuries,etc.)
In fixed income markets, bonds are the most common security traded. these are solely interest-earning investments.
depository receipts
certificates traded in one country’s market that represent ownership in shares of foreign company
mutual funds
-money pooled from different investors for the purpose of investing in securities as equity fixed income and derivatives.
-you can only trade them at 4pm. one price/day
-disclosed every quarter
open-ended funds
redeemable at any time.An Open-End Fund is a type of investment vehicle that uses pooled assets, allowing for ongoing new contributions and withdrawals from investors1. It is a diversified portfolio of pooled investor money that can issue an unlimited number of shares1. The fund sponsor sells shares directly to investors and redeems them as well1. These shares are priced daily based on their current net asset value (NAV).
exchange traded funds
a combination of mutual funds and stocks. tracks the performance of an index of share returns for a particular country or sector.
how are equities traded?
securities are bought and sold in two main markets. primary and secondary
primary market
firms raise capital by issuing new securities like equities and bonds. IPOs and seasoned new issues (new equity offered by a company that already has floated equity)
secondary market
purchase and sale of already issued securities among investors done (e.g. stock market)
4 types of secondary markets
- direct search markets
- brokered markets
- dealers market
-auction markets
direct search market
buyers and sellers find each other, directly characterized by limited participation, low-prices, and non-standard goods
brokered markets
brokers facilitate buyers and sellers meetings based on comissions or brokerage
dealers market
dealers buy securities for their own accounts and sell these securities later for profit. (price bought minus price sold)
auction markets
buyers and sellers converge at one place and bid for securities
arithmetic average
does not given equivalent per period returns
geometric average
gives equivalent per period returns
market orders
execute at current market (bid/ask) prices. adv. order execution guaranteed (immediate) disadv. uncertainty about execution price.
limit order
allows investors to buy/sell securities at a specific price (or better)
adv: max profits - orders to buy(sell) at maximum(minimum) price
no oversight
time bound execution
disadv: no protection against loses
stop orders
help minimize losses, trades will not be executed unless price hits the “stop price”
trading on margins
-margin accounts allow investors to borrow money to invest.
- refers to collateral against the fall in value of investments
- investors need to provide security whenever their account values fall below the amount of money they have borrowed
- margin ratio = MV - loan/MV
margin call
if the margin of your account falls below a certain level, (the maintenance margin) the broker will issue a margin call. you’ll need to deposit more money or sell securities to meet the margin requirement.
probability theory
- assume stock returns are continuous random variables
-how is this probability distributed? generated from the probability distribution functions - thus random variables are completely characterized by their PDFs
mean variance criterion
the expected (mean) return- standard deviation trade-off is equivalently known as mean-variance criterion.
- asset A dominates asset B if:
E(ra)>E(rb) and Oa=Ob
portfolio construction process
- specify the return characteristics of all securities (E(r), O, covariance)
- calculate the optimal risky portfolio (max sharpe ratio)
- allocate funds b/w the optimal risky portfolio and the risk-free asset
-determine the level of risk aversion
- calculate the fraction of the complete portfolio allocated to optimal risky portfolio and to risk-free asset (T-bill)
Markowitz Model
-his model is “step one”. that is, identifying the efficient set of portfolios (efficient frontier)
- efficient portfolio = minimum variance portfolio for a given level of expected return & correlation structure
- any (mean-variance) investor should choose an efficient portfolio to benefit from diversification
-a portfolio manager can form a set of efficient portfolios by running an optimization program over given characteristics of securities.
markowitz steps
step 1: risk-return opportunities available to the investor. these are summarized by the minimum-variance frontier
step 2: search for the “optimal risk” portfolio P with highest sharpe ratio
step 3: choose appropriate mix of ORP and T-bills to form OCP
- having formed the efficient frontier, we choose a portfolio P which is at the tangency point of the efficient fronteir and with the highest sharpe ratio
two fund separation theorem
- suggests you can separate the problem of investing into 2 funds:
- optimal risky portfolio
- risk free asset
weight of an asset in the optimal risky portfolio is the weight of that asset in the market portfolio
capital asset pricing model (CAPM)
- CAPM helps to fill in the gap about what should be expected returns of the assets
market price of risk
quantifies the marginal return that investors demand to bear one unit of portfolio risk
CAPM assumptions
- many small investors w endowment (initial wealth) that is small compared to total wealth in the economy. investors are price takers not price makers
- identical holding periods for all investors for simplicity
- can invest only in publicly-traded financial assets, such as stocks, bonds, and risk free assets (zero net supply)
- no taxes and transaction costs
- investors are rationale - mean variance optimizers
- investors have homogenous expectations and beliefs
- these ensure that the frontier is the same for every investor, and all investors optimal portfolio have a fraction of initial wealth invested in risk-free asset and rest in identical ORP
CAPM application
step 1: identify your “optimal risky portfolio” or market portfolio - commonly used proxy for the market portfolio is value weighted stock portfolio
step 2: get the historical data of prices (incl. dividends) for stocks, market index, and risk-free assets
step 3: calculate historical returns of these assets
setp 4: regress historical returns of the stocks on market portfolio returns to get beta coefficient for each stock
step 5: apply capm formula
