Portfolio management is all about money management. When you receive your salary you plan how to manage your savings and investments. This planning is what can be simply understood as portfolio management.
Let us take an example. I recently received a bonus of Rs. 1,40,000. Now I was planning how to manage the investments.
The options I have are:
- Investing in G-sec 3 year paper offering a 6.5% return ( No credit risk as it has sovereign backing i.e. it is the risk free rate)
- Investing in Term Deposits of 3 years in Nationalized Bank offering 8.5% return (Small risk at all as the bank is Government owned – trust factor high)
- Investing in Term Deposits of 3 years in Private Banks offering 9.00% return (Medium risk as the bank is privately held – trust factor lower)
- Invest in a 3 year rated NCD (bond) of a pharmaceutical company offering 9.15% annual coupon - return ( Moderate high risk)
- Investing in Equity Mutual Fund that has offered a CAGR return of 20% last 5 years, though last year it gave a negative return of -15%. ( High Risk)
- Investing in Direct Equity where returns can vary from -100% to 400% (Very high risk)
We observe that investment with higher risk offer higher returns.
But I also observe the inflation in current period is 3% i.e. the prices of the commodities are increasing at 3%. So the real interest I would receive on my investments would be much less.
How?
Suppose I am considering whether to Spend Rs. 10000 and buy a mobile this year or invest the money at 6.5% G-sec (nominal risk free rate) and postpone the purchase for the next year.
If I invest in G-sec I would receive Rs.10650 after year 1. But the inflation level is at 3%. So the same mobile phone would be available for Rs. 10300.
So effectively I have gained Rs. 350 by postponing my purchase.
What is the real risk free rate?
At the first look one would say the risk free rate is 3.5% (Nominal risk free rate – inflation). But it is normally a little less than 3.5%.
What is the risk?
The risk is danger of losing money (Capital Erosion). This could happen due to many of the following reasons. I would do a quick SWOT analysis of the alternatives.
- Counterparty Risk: Here the level of trustworthiness matters. We believe the government for sure would not default on its obligations. Here the Counterparty risk is almost zero.
- Business Risk: When I am consider buying the NCD of pharmaceutical firm I have to look into its business model, future growth and industry outlook.
- Exchange rate risk: If the pharmaceutical company has major business abroad, the currency fluctuations would impact its earnings.
- Liquidity Risk: If I make the investment in the NCD whether I would be able to sell the same in the secondary market. This risk is also is relevant to stocks. Stocks with high liquidity (i.e. no. of shares that get traded in a day) could be sold easily at the exchange.
- Political Risk: If a government abroad where the pharmaceutical company has operations intends to impose heavy duties on imports, it is a political risk.
- Financial risk: If the pharmaceutical company is increasing its Debt exposure to 80% from 50% there will be significant increase in interest expense (the amount to service the 9.15% interest offered). This will heavily impact its net earnings. This reduction in earnings is a financial risk.
What is security market line? (The high risk - high return game)
From the above example each alternative offers a return at a level of risk. If we plot it, then the line representing the same is called Security market line.
The slope of this line would change with the return expected for a given level of risk.
Level of risk
The level of risk taking ability differs from person to person.
- Usually people who are young with fewer responsibilities (No spouse, no children) on their shoulders would look at riskier investments. (Age is a factor)
- If I have surplus funds at my disposal I would look to invest in riskier assets. (Income / wealth matters)
- I belong to a risk-averse south Indian family and would invest in less riskier assets than a member from Business family. (Family matters)
- The last year stock market debacle saw me lose large chunk of my wealth. I am psychological dis-inclined to invest in stock markets (Psychology also matters)
My investment objectives
The investment objectives would depend on whether
- If I look to preserve my wealth I would invest in least risky assets (G-sec papers).
- I look to make some quick fast money I would invest in stocks.
- If I look to earn moderate returns and generate income of my investment I would invest in Pension Funds (I am associated with the India’s largest pension fund company as on 30th july 2009).
- My investment objective could also be a combination of all the above three.
My investment constraints
When I am planning an investment I also have some constraints
- First is limited money to invest ( Only Rs. 1,40,000)
- For what time period I am planning to lock in my amount before I use it for my consumption
- Whether I would get tax-exemption under 80C and if yes how much for my choice of investments.
- Does the government/ law mandate I make donations to PM relief fund every year.
- Whether I personally approve of my investments in tobacco, Casino running, Liquor producing company or I follow the shariah norms
So what do I do?
I remember Mr. Markowitz who developed the portfolio modeling technique. His golden words were:
- If A and B offer the same return but B is riskier then please choose A. It maximizes your fund utility.
- If C offers a return in the range of -10% to 20% and D offer -30% to 50% then please choose according to your risk aversion levels taking variance and standard deviation into account.
- Please calculate the return you expect out of your investment and probability that such a return would get generated.
- All the points are nothing but weighing the Risk Reward on your investment alternatives and by following these you would be able to develop an optimal portfolio on efficient frontier (nothing but a set of optimal portfolio according to risk appetite of investors).
