Security Analysis for CA Final AFM: Chapter Study Guide

Security Analysis is the process of estimating what a share or bond is worth and comparing it with its market price. You use fundamental analysis, technical analysis, market efficiency ideas, equity models such as the dividend discount model, and bond pricing with yields. Solve by writing the formula, computing step by step, then stating a buy, sell or hold view.

What this chapter covers

Security Analysis asks one question: is this security fairly priced? You answer it in two broad ways. Fundamental analysis looks at the economy, industry and company to estimate intrinsic value. Technical analysis looks at price and volume patterns to judge likely direction. The Efficient Market Hypothesis tells you how far either approach can be expected to work.

The numerical core of the chapter is valuation. For equity you discount expected dividends or use earnings-based measures such as the P/E ratio. For bonds you discount coupons and the redemption value, and then measure return through yield to maturity, current yield, duration and related measures. These are calculation-heavy, and they reward a clear formula and neat working.

The chapter connects to the rest of AFM in several ways. Valuation ideas feed into portfolio management, where you need expected return and risk for each security. Bond pricing links to interest rate risk and derivatives. The cost of equity and the growth ideas you use here also appear in capital structure, dividend decisions and business valuation. In Paper 6, you may be asked to judge a security or an investment proposal in a case, using the same reasoning.

This chapter gives you a good mix of theory and numbers. The theory parts (types of analysis, chart patterns, forms of market efficiency) suit case-scenario MCQs and short written answers, where you must apply a concept to a described situation. The numerical parts (dividend growth models, P/E-based value, bond price and yield) follow fixed methods, so with practice you can score reliably. Because the formulas are also reused in portfolio, capital structure and valuation topics, time spent here pays off across the paper. Students who skip it often lose easy marks and later struggle with related chapters.

Security Analysis: topics in the order to study them

1Fundamental AnalysisIt sets the idea of intrinsic value versus market price, which every later topic builds on.
2Technical Analysis and ChartsIt is the contrasting approach, mostly theory and chart reading, so it is quick to learn once fundamentals are clear.
3Efficient Market HypothesisIt lets you judge whether fundamental or technical analysis can beat the market, tying the two approaches together.
4Equity Valuation ModelsIt turns intrinsic value into numbers using dividends, growth and earnings multiples, and needs the earlier concepts.
5Bond Valuation and Yield MeasuresIt uses the same discounting logic as equity models, applied to fixed cash flows, so it is easier to learn last.

How to prepare Security Analysis

Prepare this chapter in a mix of understanding, formula practice and timed questions. Keep your formulas on one page and revise them often.

Read the theory topics first and make a one-page note: what each analysis uses, what each claims, and its main limitation.
Learn the three forms of market efficiency (weak, semi-strong, strong) with the information each assumes is already in prices, and what that implies for each type of analysis.
Write each equity model with its conditions. For example, a constant growth model needs the required return to be higher than the growth rate.
Solve at least five equity valuation questions in full: compute value, compare with market price, then state buy, sell or hold.
Solve bond questions in two steps: price from cash flows and a discount rate, then yield from price. Check that a higher yield gives a lower price.
Practise case-scenario MCQs where you pick the right concept for a described situation, such as which form of efficiency a news event tests.
Do a timed revision set at the end. Write the formula, the working and a one-line conclusion each time.

Common mistakes in Security Analysis

Using D₀ instead of D₁ in the constant growth model.
Fix: Check whether the dividend is already paid or expected next. If it is the last dividend, multiply by (1 + g) first.
Applying the growth model when growth is equal to or higher than the required return.
Fix: Test ke > g before using it. If growth is temporary, use a multi-stage approach and value each stage separately.
Mixing up the forms of market efficiency.
Fix: Link each form to the information set: past prices, public information, all information. Then say what that means for technical and fundamental analysis.
Discounting bond cash flows at the coupon rate instead of the required yield.
Fix: Always discount at the market required return or yield. The coupon only sets the cash flow.
Stopping at the number without a conclusion.
Fix: End with a line such as: intrinsic value ₹X is above market price ₹Y, so the share is undervalued and a buy is suggested.
Treating chart patterns as certain predictions in theory answers.
Fix: Describe patterns as indicators and add the limitations, such as subjectivity and the argument from market efficiency.

Last-day revision: Security Analysis

Intrinsic value is what analysis says a security is worth. Compare it with market price to decide buy, sell or hold.
Fundamental analysis moves from economy to industry to company (top-down).
Technical analysis uses past price and volume to predict direction. It assumes trends tend to continue.
Weak form: prices reflect past price data. Semi-strong: all public information. Strong: all information, including private.
If markets are weak-form efficient, technical analysis should not give consistent excess returns.
Constant growth model: P₀ = D₁ ÷ (ke − g), valid only when ke > g.
D₁ = D₀ × (1 + g). Do not use D₀ in place of D₁.
P/E-based value = expected EPS × appropriate P/E multiple.
Bond price = present value of coupons + present value of redemption value, discounted at the required yield.
Bond price and yield move in opposite directions.
Current yield = annual coupon ÷ current market price.
A bond selling below face value has a yield to maturity above its coupon rate.

Security Analysis: frequently asked questions

Is Security Analysis more theory or numericals in CA Final AFM?

It has both. Fundamental analysis, technical analysis and market efficiency are mostly theory, and equity and bond valuation are numerical. You should prepare for case-scenario MCQs and written answers on both types.

Which formulas should I learn first in this chapter?

Start with the constant growth dividend model, P/E-based valuation, bond price as a present value, and current yield and yield to maturity. Then add duration-type measures as your syllabus and study material require.

How do I decide between buy, sell and hold in a valuation question?

Compute intrinsic value and compare it with market price. If value is higher, the security looks undervalued and a buy is suggested. If it is lower, it looks overvalued and a sell is suggested. If they are close, hold.

Do I need to memorise chart patterns?

Know the main ideas well enough to explain what each signals and what its limits are. You are more likely to be asked to interpret or explain a pattern than to draw one from memory.
