3. Concept of Portfolio A person’s wealth portfolio includes
Assets: stocks, bonds, shares in unincorporated business, houses or apartments, pensions benefits, insurance policies, etc.

4. Portfolio Selection
A study of how people should invest their wealth optimally
A process of trading off risk and expected return to find the best portfolio of assets and liabilities
Narrow and broad definitions:
How much to invest in stocks, bonds, and other securities
Whether to buy or rent one’s house
What types and amounts of insurance to purchase
How to manage one’s liabilities
How much to invest in one’s human capital

5. Cont…
Although there are some general rules for portfolio selection that apply to virtually everyone, there is no single portfolio or portfolio strategy that is best for everyone.

6. The Life Cycle
In portfolio selection, the best strategy depends on an individual’s personal circumstances (family status, occupation, income, wealth).
Illustrations
Young couple: buy a house and take out a mortgage loan /
older couple: sell house and invest in assets providing a steady stream of income.
Buying insurance policies: Miriam (a parent with dependent children) / Sanjiv (a single person with no dependents).

7. Time Horizon
In formulating a plan for portfolio selection, you begin by determining your goals and time horizons.
Planning horizon: the total length of time for which one plans
Decision horizon: the length of time between decisions to revise the portfolio
Trading horizon: the minimum time interval over which investors can revise their portfolios / its determination and impacts
Investment strategy & trading horizon: portfolio insurance or dynamic portfolio strategy.

8. Risk Tolerance A major determinant of portfolio choices
It is influenced by such characteristics as
age, family status, job status, wealth, and
other attributes that affect a person’s ability to maintain his standard of living in the face of adverse movements in the market value of his investment portfolio

9. The Trade-off between Expected Return and Risk
The objective is to find the portfolio which offers investors the highest expected rate of return for the degree of risk they are willing to tolerate.
Two step process:
find the optimal combination of risky assets.
mix this optimal risk-asset with the riskless asset.

10. Riskless Asset
A security that offers a perfectly predictable rate of return in terms of the unit of account selected for the analysis and the length of the investor’s decision horizon.
For example, if the U.S dollars is taken as the unit of account and the decision horizon is half a year, the riskless rate is the interest rate on U.S Treasury bills maturing after half a year.

11. Rates of Return on Risky Assets
Required return depends on the risk of the investment.
Greater the risk, greater the return
Risk premium

13. Combining the Riskless Asset and a Single Risky Asset: An illustration
Let’s suppose that you have $100,000 to invest.
You are choosing between a riskless asset with a interest of 6% per year and a risky asset with an expected rate of return of 14% per year and a standard deviation of 20%.
How much of your $100,000 should you invest in the risky asset?

16. Selecting the Preferred Portfolio
It is important to note that in finding the optimal combination of risky assets, we do not need to know anything about investor preferences.
There is always a particular optimal portfolio of risky assets that all risk-averse investors who share the same forecasts of rates of return will combine with the riskless asset to reach their most-preferred portfolio.

Efficient Frontier
The jelly fish shape contains all possible combinations of risk and return: The feasible set.
The red line constitutes the efficient frontier of portfolios of risky assets: Highest return for given risk.
The tangent portfolio T is the optimal portfolio of risky assets that all risk-averse investors will combine with the riskless asset.
