Investments Chapter for NISM PMS Distributors Exam

The Investments chapter of NISM-Series-XXI-A covers how portfolios are built and judged: asset classes, risk and return, equity and bond valuation, diversification, performance ratios and derivatives. You solve it by learning each formula in plain words, practising short numerical questions, and knowing what each measure tells a client.

What this chapter covers

This chapter is the investment theory base for the PMS Distributors paper. It starts with the investment process and asset classes, then moves to risk and return, valuation of equity and bonds, portfolio theory, performance ratios and derivatives. Each topic gives you a tool to understand what a portfolio manager does.

Most questions are either definition-based or short calculations. You may be asked to compute a return, a P/E-based value, a bond price relationship, a beta-based expected return or a ratio such as Sharpe. Other questions test whether you can pick the right concept for a situation.

The chapter connects to the rest of the paper because a distributor must explain PMS strategies, risk and fees to clients in plain terms. The regulatory and product chapters tell you what is allowed. This chapter tells you why a strategy behaves the way it does and how to judge its results fairly.

The exam is 100 one-mark MCQs with negative marking of 10% of the marks assigned to a question, and the pass mark is 60%. A chapter that mixes concepts and calculations rewards precise preparation and punishes guesswork. The formulas are few and repeat across questions, so steady practice here gives dependable marks. The same ideas also help you answer questions in other chapters on suitability, risk profiling and performance reporting.

Investments: topics in the order to study them

  1. 1Investment Process and Asset ClassesIt gives the vocabulary and the big picture that every later topic builds on.
  2. 2Risk and Return ConceptsReturn, standard deviation, beta and correlation are used in almost every topic that follows.
  3. 3Equity Investments and ValuationIt applies return and risk ideas to shares, using ratios and basic valuation models.
  4. 4Fixed Income Securities and Bond ValuationBond pricing, yield and duration are a separate toolset, easier once you know how valuation works for equity.
  5. 5Modern Portfolio Theory and DiversificationIt combines assets, so you need risk, return and correlation clear before you study it.
  6. 6Performance Measurement RatiosSharpe, Treynor and alpha rest on beta, standard deviation and the risk-free rate from earlier topics.
  7. 7Derivatives and Their Use in PortfoliosIt is best last, as hedging and overlay uses make sense only after you understand portfolio risk.

How to prepare Investments

Treat this as a concept-plus-calculation chapter. Aim to understand each measure well enough to explain it to a client in one sentence.

  1. Read each topic once for meaning, and write a one-line plain-words definition of every term.
  2. Make a single formula sheet. Write each formula in words first, then in symbols, and note what a higher or lower result means.
  3. Solve five to ten short numerical questions per topic by hand, with units and percentages checked.
  4. Learn the direction of relationships, such as bond prices falling when yields rise and higher beta meaning higher market sensitivity.
  5. Do topic-wise MCQs, then review every wrong answer and note which trap option you chose.
  6. In mixed practice sets, attempt only questions where you can eliminate at least two options, since wrong answers carry a penalty.
  7. Revisit your formula sheet and error notes in the last two days instead of starting new material.

Common mistakes in Investments

  • Mixing up Sharpe and Treynor ratios.

    Fix: Remember the denominator: standard deviation for Sharpe, beta for Treynor. Total risk versus systematic risk.

  • Using percentages inconsistently in calculations.

    Fix: Convert everything to one form before you start and check that the answer is sensible.

  • Believing diversification removes all risk.

    Fix: Link diversification only to unsystematic risk. Market-wide risk remains.

  • Getting the direction of bond price and yield wrong.

    Fix: Remember that a higher discount rate lowers the present value of fixed cash flows, so price falls.

  • Confusing beta with standard deviation.

    Fix: Beta compares movement with the market; standard deviation measures total variability on its own.

  • Guessing every unfamiliar question.

    Fix: Guess only after eliminating options, and skip questions where you have no basis for a choice.

Last-day revision: Investments

  • Asset classes differ in risk, return, liquidity and tax treatment; equity is usually the most volatile of the main classes.
  • Standard deviation measures total risk; beta measures sensitivity to the market and so only systematic risk.
  • Diversification reduces unsystematic risk but cannot remove systematic risk.
  • Lower correlation between assets gives greater diversification benefit; a correlation of +1 gives none.
  • CAPM: expected return = risk-free rate + beta × (market return − risk-free rate).
  • P/E = market price ÷ earnings per share; dividend yield = dividend per share ÷ market price.
  • Bond prices and yields move in opposite directions.
  • A bond's price is the present value of its coupons and principal at the required yield.
  • Higher duration means higher sensitivity of price to interest rate changes.
  • Sharpe ratio = (portfolio return − risk-free rate) ÷ standard deviation, so it uses total risk.
  • Treynor ratio = (portfolio return − risk-free rate) ÷ beta, so it uses systematic risk.
  • Alpha is return earned beyond what beta and market return explain.
  • Derivatives derive value from an underlying; in portfolios they are used for hedging, not only speculation.

Investments: frequently asked questions

How many formulas do I need to know for the Investments chapter?

A small set covers most questions: return, CAPM, P/E and dividend yield, bond price and yield relationships, and the Sharpe and Treynor ratios. Learn each in words and symbols. Practise a few numerical questions on each.

Is the Investments chapter mostly calculations?

No. It mixes definitions, relationships and short calculations. Many questions test whether you understand what a measure shows, so concept clarity matters as much as arithmetic.

What is the negative marking in NISM-Series-XXI-A?

The revised exam, effective 15 March 2025, has negative marking of 10% of the marks assigned to a question. Each question is 1 mark, so a wrong answer costs 0.1 mark. Avoid blind guessing but do not leave answerable questions.

Which topic should I study first in this chapter?

Start with Investment Process and Asset Classes, then Risk and Return Concepts. Almost every later topic uses risk and return ideas, so these two make the rest easier.
