-Investors buy shares to receive returns from dividends & capital gains (can be losses)
-Factors encouraging investment in securities quoted on stock exchange:
Depth of market - market capitalisation
Liquidity of market - volume of trading relative to size of market
Efficient price discovery - speed & efficiency with which new information is reflected
in current share price (ie continuous reporting)
-Systematic Risk: Exposures that affect the price of the majority of shares listed on a
stock exchange (e.g. interest rates, exchange rates, economic growth)
-Unsystematic Risk: Exposures that specifically impact on the share price of a
particular corporation
e.g. resignation of CEO, performance forecasts, technology failure, dissent within
board of directors
-Diversified Investment Portfolio: (10-25 stocks)
Investment portfolio that includes a wide range of financial securities & assets
Diversifies away unsystematic risk exposure of individual securities
-Investors don’t receive higher returns for unnecessarily bearing unsystematic risk
Remaining risk is systematic risk - measured by beta (average beta = 1.0)
-Statistical measure of the sensitivity of an asset price relative to the market
Systematic risk of investment portfolio is given by the weighted average of the beta
of individual shares
Expected portfolio return - weighted average of expected returns of each share held
Portfolio variance (risk) - variability of returns of an investment portfolio over time
-Result of variance of each individual investment contained within portfolio & the
co-variance or correlation between pairs of securities
-Co-variance/ correlation - measures how two share prices move relative to each
other; either positive (same direction) or negative (opposite directions)
Two approaches to investment:

-Active investment approach - portfolio structure based on share analysis, new
information & risk/return preferences (fundamental & technical analysis)
-Passive investment approach - portfolio structure based on replication of a
specific share-market index (ASX 200) or sector index (telecommunications)
-Some managed funds are index funds - acquire shares so that portfolio fully or
partially replicates a specific share-market index
Considerations:
-Risk vs return (systematic & unsystematic risk, beta & diversification)
-Investment time horizon - portfolios on average, earn higher returns over longer
investment time horizon of 5 years or more
-Income vs capital growth - different liquidity needs (preference of regular
dividends or price increases; capital gains)
-Domestic & international share investments - diversified share portfolio typically
includes stocks from home markets & selection of international share markets
Strategic asset allocation - portfolio structured to meet investor’s personal
preferences (cash-flow requirements, tax position, risk tolerance etc)
Tactical asset allocation - portfolio structured to take account of dynamic investment
environment
-Buying & Selling Shares:
Considerations:
-Liquidity - how easily shares can be converted to cash (sold)
-Risk - including variance, standard deviation, beta, volatility
-Integrity - of company, management & share market
-Charges - transaction costs (fees on managed funds, brokerage on direct
transactions through stockbroker
-Return - type of expected return (dividends, capital growth)
-Capital growth - factors affecting level of growth (inflation, interest rates,
economic & business cycles)
-Accessibility - depth & liquidity of primary & secondary markets
-Flexibility - portfolio restructuring, active investment, passive investment
-Taxation - income tax, capital gains tax, dividend imputation (if available)

-Social security - effect of investment on income test & assets test associated with
social security benefits (if applicable)
Direct investment - investor buys & sells shares directly through a stockbroker
Stockbroker - acts as agent for a investor in buying & selling of stock-market
securities
-Discount broker executes buy & sell orders for clients; no investment advice or
services
-Full-service advisory broker executes buy & sell orders but also provides other
services to clients, including investment advice
Indirect investment - investing through a funds manager in a unit trust or managed
fund (e.g. equity trusts)
-Fees may include entry, exit, administration costs & are usually higher than direct
investment fees
-Taxation:
Marginal rate of tax - percentage of income tax paid progressively increases relative
to the amount of income earned
Pre-dividend imputation (prior to 1987) - dividends taxed twice
-At company level (as profits) then at investor’s marginal rate
Dividend imputation (since 1987) - removed double taxation of dividends
-Investors receive franking credit for tax a company pays on a franked dividend
Capital gains tax on shares:
-Tax free prior to 19/9/85
-19/9/85 - 21/9/99
Taxpayer’s marginal tax rate applied if held less than 12 months
Taxpayer’s marginal tax rate applied to indexed capital gain if held over 12
months
-Since 21/9/99
50% discounted gain if held at least 12 months
Indexed capital gain or 50% discounted gain if purchased between 19/9/85 &
21/9/99
