Why this chapter comes first
A PMS distributor sells a product meant for wealthy, fairly sophisticated clients. But the exam starts at the very bottom: what investment is, what return is made of, and what can go wrong. Get these ideas clean and every later chapter becomes easier.
Life does not match income to spending
People pass through phases. In some phases they earn more than they spend. In others they earn less than they spend. The workbook's point is simple: income and spending rarely match.
So people with a shortfall borrow, and people with a surplus lend. The borrower must be willing to repay more than they received. The lender postpones consumption today in exchange for a larger amount later.
Saving is not investing
The exam wants these two words kept apart.
- Saving is just the difference between money earned and money spent.
- Investment is the current commitment of savings with an expectation of receiving a higher amount later. It involves a specific time period. It is making savings work to generate return.
The workbook draws three contrasts:
| Saver | Investor | |
|---|---|---|
| Where the money goes | Short-term deposits and short-term securities — highly liquid | Real assets, stocks, bonds and other long-term commitments — may be less liquid |
| Goals | Short-term | Longer-term — retirement corpus, children's college |
| Relationship | Has the choice of investing | Must have saved first |
And the line to memorise: "every investor is a saver but not vice versa."
Financial assets and real assets
Financial assets — shares, debentures, bank deposits, public provident fund, mutual fund investments. Physical (real) assets — gold, diamonds, other precious metals, real estate.
The workbook lists the advantages of financial assets: greater liquidity, flexibility, convenience of investing and ease of maintaining the investment. They are primarily income generating, though equity-oriented ones are held for long-term capital appreciation. They also allow small and frequent investments.
Investment versus speculation
These two are "so intermingled" that separating them is very difficult. The workbook offers two ways to try — time horizon and the process of decision making — and then knocks down the first one.
Time horizon. Transactions happen on a continuum from micro-seconds to perpetual holdings. There is a tendency to call short-term activity speculation and long-term ownership investment. The workbook says this is not appropriate.
Decision process. This is the useful test. The dictionary meaning of speculation is "the forming of a theory or conjecture without firm evidence".
- An investor carries out a process to find the value of an asset, and buys when the intrinsic value is higher than the current market price.
- A speculator pays no cognizance to the value of the asset. Profit making is the sole purpose, without much consideration of the risk involved.
So holding period does not decide it. Whether you valued the asset decides it.
Investment objectives
The workbook defines investment objectives as goals expressed in terms of risk, return and liquidity preferences.
Many investors state goals only as return — "I want my money to double this year." That is dangerous. Stating goals only in return terms can lead to inappropriate asset allocation and risky strategies. The investor must understand that "risk leads return" and not the other way around. So a detailed look at risk appetite — her willingness and ability to take risk — should come before any discussion of desired return.
The return objective comes in four flavours:
| Objective | What it means | Who it suits |
|---|---|---|
| Capital preservation | Minimise or avoid erosion of principal | Highly risk-averse investors; money needed in the immediate short term |
| Capital appreciation | Portfolio value grows over time; risk accepted | Long-term investors |
| Current income | Regular income — dividend, interest, rent — rather than growth | Mostly retired people meeting living expenses |
| Tax saving | Using avenues that give deductions from taxable income or a tax rebate | Anyone reducing their tax burden |
What a required return is made of
When you commit a rupee for a period, you want paying for three things:
- Pure time value of money — because you postponed consumption.
- Compensation for expected inflation — because prices will change.
- A risk premium — because future payments are uncertain.
Build it up in layers:
- The real risk-free rate is what you demand with no inflation and no uncertainty. It is the compensation for postponing consumption. Give up ₹1,000 today for a guaranteed ₹1,020 later and the pure rate is 2%.
- Add expected inflation and you get the nominal risk-free rate.
- Add a risk premium and you get the required rate of return.
In simple terms, for small values:
Nominal risk-free rate = Real risk-free rate + Inflation Required rate of return = Nominal risk-free rate + Risk premium
The workbook is careful about what the required rate is not. It is the minimum return investors expect. It is not a guaranteed or assured return. It is different from expected or forecasted return. It is different from realised return.
Time value of money
Money today is worth more than the same money tomorrow, because today's money can be invested and earn a return. Invest ₹100 at a risk-free 5% and after a year it is ₹105 — that is its future value. Going the other way, ₹105 due in a year is worth ₹105 ÷ 1.05 = ₹100 today — its present value.
What sets the real risk-free rate? An interaction between a subjective factor — the desire for current consumption — and objective factors — the investment opportunities available and the real growth rate of the economy.
Risk premium and the risk–return line
A government security (with some caveats) gives a return you are certain of — both the amount and the timing. When cash flows or their timing are uncertain, investors demand extra. That extra is the risk premium. Higher the risk, higher the risk premium.
The relationship between risk and return is positive — but the workbook adds two details examiners like:
- In reality it is nonlinear. There is no proportionate increase in return for each extra unit of risk.
- The line is different for different individuals, depending on their risk appetite or risk aversion.
What "risk" means
In investments, risk is the possibility that actual earnings differ from expected earnings. Mathematically it is the dispersion around the average expected return, measured by standard deviation.
Note what that implies: a surprise on the upside is also risk in this sense.
The seven risks
| Risk | What it is | Workbook example |
|---|---|---|
| Business risk | A company fails to generate enough revenue or profit | A retailer that does not adapt to e-commerce |
| Financial risk | Losing money through market swings, credit defaults, rate changes, inflation or liquidity constraints | Affects both individuals and businesses |
| Liquidity risk | Difficulty buying or selling without significantly affecting price | Penny stocks, bonds of little-known issuers; Treasury bills have no liquidity risk |
| Exchange rate (currency) risk | Value changes with foreign exchange rates | Indian investor in US stocks loses if the rupee strengthens |
| Political risk | Government action, policy change, political instability | Sudden change in foreign investment rules; elections, protests, war |
| Geopolitical risk | International conflict, sanctions, trade disputes | A trade war; an oil supply disruption |
| Regulatory risk | Changes in laws and regulations | A sudden rise in capital gains tax; new banking rules |
The currency direction is a classic trap. For an investor holding foreign assets, home currency depreciation increases returns and appreciation reduces them.
Mitigation, per the workbook: political risk — diversify globally, invest in stable economies, monitor policy. Geopolitical risk — diversify globally, hold safe-haven assets (gold, bonds), stay informed. Regulatory risk — diversify across industries and geographies, monitor policy, prefer companies with strong compliance.
Types of investment
Financial investments (equity, bonds) are claims on future cash flows. Non-financial investments (real estate, gold, commodities) are also called real investments. The word securities generally means equity, bonds, derivatives and the like, and they are transferable.
Equity. Ownership stake; returns from capital appreciation and dividends. Empirically, higher long-run returns than other asset classes, with greater volatility. Analysed through fundamental analysis. Continuously reviewing and adjusting a portfolio to match market conditions and risk tolerance is called rebalancing.
Fixed income. Regular interest (coupons) plus return of principal at maturity — government, corporate and municipal bonds, treasury bills. Typically less volatile than equity. Held to maturity, they generally return principal and coupons provided the issuer does not default. Government bonds are low-risk thanks to sovereign guarantees; corporate bonds pay higher yields for higher credit risk. Still exposed to interest rate risk (prices fall when rates rise), credit risk and inflation risk.
Commodities.
| Soft commodities | Hard commodities | |
|---|---|---|
| Examples | Corn, wheat, soybean, soybean oil, sugar | Gold, silver, oil, copper, aluminium |
| Nature | Perishable, so highly volatile prices | Gold and silver held as reserve assets for centuries |
| Portfolio role | Low correlation to stocks and bonds — diversification | Gold is a "safe haven" and assumed hedge against inflation |
| How to get exposure | Derivatives — forwards, futures | Prices set by global demand and supply |
And the key fact: commodities generate no current income. The investor counts only on capital appreciation.
Real estate. Residential, commercial, industrial, and special segments such as healthcare facilities and student housing. Offers both rental income and capital appreciation, and acts as an inflation hedge. Risks: market fluctuations, interest-rate-driven financing costs, liquidity risk, management time and unforeseen expenses, high upfront costs, local regulation.
Structured products. Traditional investments (bonds or equities) combined with derivatives to create customised risk–return profiles. They can offer capital protection and tailored exposure. But they are complex, often lack transparency, may be hard to trade before maturity, and carry credit risk of the issuer. Best suited to sophisticated investors — HNIs, institutions.
Non-traditional. Art, paintings, horses (prize earnings, stud fees, resale), distressed assets bought at a discount. Challenges: illiquidity, complex valuation, high transaction costs, niche market risks.
Channels: direct or managed
Direct investment — buying securities issued by companies and government bodies, or gold and silver from dealers. For financial securities, intermediaries help:
- Distributors — connect AMCs with investors; earn commissions or fees based on products sold.
- Brokers — buy and sell on exchanges; earn brokerage. Full-service (advice, portfolio management) or discount (low-cost platforms, minimal advice).
- Registered Investment Advisers — tailored advice. Some earn commission, some charge fees — but advisers are prohibited from earning both commission and fees from the same investor. SEBI-registered RIAs follow fiduciary standards.
Indirect investment through managed portfolios — professionally managed for fees, profit-sharing or both:
| Mutual Funds | PMS | AIFs | |
|---|---|---|---|
| Structure | Pooled, diversified | Tailor-made portfolio for each investor | Privately pooled vehicle |
| Minimum (per workbook) | — | ₹50 lakh | ₹1 crore |
| Ownership | Units | Direct ownership of stocks or assets | Units in the fund |
| Liquidity | Buy or sell units easily | — | Limited liquidity |
| Suits | Retail — professional management, diversification, transparency, lower cost | HNIs wanting customised strategies, higher risk, active management | Institutional and HNI investors |
PMS decisions may be discretionary or non-discretionary. AIF categories, as the workbook lists them: Category I — start-ups, VC funds, social ventures. Category II — private equity, debt funds. Category III — hedge funds, long-short funds.
Think of it like this
Saving is the grain store; investing is the sowing
A farmer keeps part of the harvest in the store room. That is saving — the surplus after the family has eaten. It is safe and ready to use, but it does not grow.
Next season he takes some of that grain and sows it. Now it is committed for a fixed period, he cannot eat it tomorrow, and he expects more back at harvest. That is investing.
Notice the order. He cannot sow grain he never stored. Every sower is a storer, but not every storer sows — which is exactly the workbook's line: every investor is a saver but not vice versa.
The required return is a three-layer thali
Think of the return you demand as a thali with three katoris.
The first katori is the real risk-free rate — plain payment for waiting, for giving up your ₹1,000 today. The second katori is inflation compensation — because the dal will cost more next year. Together these two make the nominal risk-free rate.
The third katori is the risk premium — only served when there is doubt the meal will arrive at all. A government security skips the third katori. A small company's bond gets a big third katori.
If someone quotes a single number, ask which katoris are in it.
The kirana owner who checks the price tag
Two people buy onions in bulk before the monsoon.
Ramesh has studied last year's arrivals, storage losses and the likely mandi price. He buys because onions look cheap against what he thinks they are worth. That is investing — he formed a view of value.
Suresh heard at the tea stall that "onions will shoot up". He has no idea what they are worth. He only wants the profit. That is speculation — a conjecture without firm evidence.
Both might hold for the same two months. The holding period does not separate them. The homework does.
Currency risk is the exchange counter at the airport
Priya bought US shares worth $1,000 when one dollar bought many rupees. A year later the shares are still worth exactly $1,000.
If the rupee has weakened, each of those dollars now converts into more rupees at the airport counter. Her rupee return goes up without the shares moving.
If the rupee has strengthened, each dollar fetches fewer rupees. Her rupee return goes down.
That is why the workbook says home currency depreciation increases returns on foreign assets and appreciation reduces them. The counter, not the company, did it.
