Security Analysis for CS Executive Paper 4
Security analysis is the study of how to value securities and judge their risk and return before you invest. For CS Executive Paper 4, you learn approaches to analysis, bond and share valuation, technical analysis, market efficiency and portfolio theory with CAPM. Learn the formulas, then practise numericals and short theory answers.
What this chapter covers
Security Analysis sits in Part II of Paper 4, Financial Management. It asks one question: what is a security worth, and is it worth buying at its current price? You answer it using two broad approaches. Fundamental analysis looks at the economy, industry and company. Technical analysis looks at price and volume patterns.
The chapter moves from ideas to numbers. You first learn the meaning and approaches, then measure risk and return. Next you value bonds and equity shares by discounting future cash flows. The last topics cover how markets price information (Efficient Market Hypothesis) and how to combine securities into portfolios, ending with CAPM.
This chapter connects to the rest of the paper. Time value of money and the cost of capital from earlier financial management chapters are the tools you use here. Bond yield and share valuation also feed into capital structure and dividend decisions. The chapter also links to Paper 5, where you study how securities are issued and traded.
This chapter mixes short theory answers with numericals, and the numericals follow fixed patterns that you can master with practice. Once you know the valuation formulas and the CAPM equation, you can score reliably, because the steps are mechanical and examiners expect a clear working. The theory topics, such as Dow Theory and market efficiency forms, are easy marks if you write definitions and points in an organised way. Paper 4 is a written paper, so show every step, state the formula and give a clear conclusion.
Security Analysis: topics in the order to study them
- 1Security Analysis: Meaning and ApproachesIt gives you the vocabulary and the fundamental versus technical split that the rest of the chapter builds on.
- 2Risk and Return of SecuritiesYou need expected return, variance and standard deviation before you can value securities or build portfolios.
- 3Valuation of Bonds and DebenturesBond valuation is the simplest discounting exercise, with fixed cash flows, so it is the best place to start numericals.
- 4Valuation of Equity SharesIt extends discounting to uncertain dividends, using the dividend discount and growth models, and relies on the bond method.
- 5Technical Analysis and Dow TheoryThis is mostly theory, so it gives a break from numericals and completes the second approach introduced at the start.
- 6Efficient Market HypothesisIt tests whether either approach can beat the market, which makes sense only after you know both.
- 7Portfolio Theory and CAPMIt uses risk and return from earlier and ends the chapter by linking risk to required return.
How to prepare Security Analysis
Study this chapter in two tracks: formula-based numericals and point-based theory. Give numericals more practice time, and keep theory in short, structured notes.
- Read the meaning and approaches first, and write a one-page comparison of fundamental and technical analysis.
- Learn the risk and return measures, then work through expected return and standard deviation sums until you can do them without looking at the formula.
- Practise bond valuation by listing the cash flows, discounting each one, and adding them. Do this for bonds with interest, zero-coupon bonds and redeemable bonds.
- Practise equity valuation with the constant growth model and multi-stage dividend cases. Always check that the required return is higher than the growth rate before you apply the constant growth formula.
- Make short notes for Dow Theory and the three forms of market efficiency, each with a definition and what it implies for investors.
- Solve CAPM and portfolio return and risk problems, and write the formula, the substitution and the final conclusion in each answer.
- Finish with timed past-paper questions and write full answers as you would in the exam.
Common mistakes in Security Analysis
Using D₀ instead of D₁ in the constant growth model.
Fix: Check whether the dividend given is the last one paid or the next expected one. If it is the last paid, multiply by (1 + g) first.
Applying the growth formula when growth is higher than or equal to the required return.
Fix: Write k > g as a check before every use. If it fails, the model does not apply and you should say so.
Discounting bond cash flows at the coupon rate instead of the required return.
Fix: Coupon rate sets the interest amount. The market yield or required return is the discount rate.
Confusing the three forms of market efficiency.
Fix: Remember it as nested: weak covers past prices, semi-strong adds public information, strong adds private information.
Mixing up total risk and systematic risk in CAPM answers.
Fix: Use standard deviation for total risk and beta for market risk. CAPM uses beta only.
Writing only the final number in numericals.
Fix: Write the formula, substitution, calculation and a one-line conclusion, such as whether the security is overvalued or undervalued.
Last-day revision: Security Analysis
- Fundamental analysis studies economy, industry and company; technical analysis studies price and volume.
- Expected return = Σ (probability × return).
- Standard deviation is the square root of variance, and it measures total risk.
- Bond value = present value of interest payments + present value of redemption value, discounted at the required return.
- Zero-coupon bond value = redemption value ÷ (1 + r)ⁿ.
- Constant growth model: P₀ = D₁ ÷ (k − g), valid only when k > g.
- D₁ = D₀ × (1 + g).
- Dow Theory describes primary, secondary and minor trends in the market.
- Weak form efficiency says past prices cannot predict future prices; semi-strong adds public information; strong adds all information including private.
- CAPM: Expected return = Rf + β × (Rm − Rf).
- Beta measures systematic risk, which diversification cannot remove.
- Diversification reduces unsystematic risk only.

Security Analysis: frequently asked questions
Is Security Analysis a numerical or theory chapter?
It has both. Bond valuation, share valuation, risk and return and CAPM are numerical. The approaches, Dow Theory and market efficiency are theory. Prepare both, because a written paper can ask either.
Which part of Paper 4 does Security Analysis belong to?
It belongs to Part II, Financial Management, which carries 40 marks of the 100-mark paper. Part I, Corporate Accounting, carries 60.
How should I learn the valuation formulas?
Understand that each one is a present value of future cash flows. Then practise a few sums of each type. Understanding the logic helps you rebuild a formula if you forget it in the exam.
Do I need to draw charts for technical analysis?
Not usually for a theory answer, but a simple labelled sketch of a trend can help. Focus first on explaining the concepts clearly in words.
