NISM Series XV · Chapter 4: Fundamentals of Research
L1 · FoundationFundamentals of Research — the ground floor
What investing actually is (and how it differs from trading, speculation and day trading), what a research analyst does all day, the line between mosaic analysis and insider information, and the four ways people analyse a stock — technical, fundamental, quantitative and behavioural. Plus the commodity chapter: gold, crude oil, and why a commodity move shows up in equity prices.

Chapter 4 is the map, not the territory
Every later chapter of this workbook — economy analysis, industry analysis, company analysis, valuation, risk and return, technical analysis — is a detailed drawing of one region. Chapter 4 is the map that shows you where those regions sit and how they connect.
That makes it easy to skim and easy to lose marks on. The chapter is built almost entirely out of definitions and distinctions, and NISM tests definitions and distinctions with surgical precision.
4.1 What is investing?
The workbook's definition, worth reading twice:
Three components sit inside that sentence:
- An upfront commitment of money — you part with capital now.
- An investment horizon — a period over which the return is expected.
- Thorough analysis across three dimensions: safety/risk, income, and growth potential.
Then comes the line the exam loves: "Investing is very distinct from trading or speculative activities."
Trader, speculator, chartist, day trader
A trader tries to earn a spread between selling price and buying price without a necessary change in the underlying value of the asset. Read that carefully. The trader is not claiming the business got better. The trader is claiming the price will move. Traders are motivated by a historical price pattern and its re-occurrence in future, and so a trader's time horizon is usually short.
The workbook then gives you three sub-labels, and questions are built directly on them:
| Label | The defining feature |
|---|---|
| Speculator | Bets on short-term movement of asset prices based on a calculated guess, taking a position in anticipation of profits if the guess is right |
| Chartist | Depends on price patterns and related charting techniques |
| Day trader | The entire investment and disinvestment cycle is 1 day |
Investment activity, by contrast, focuses on the potential of an asset's value to increase over a period. And the workbook gives the exact mechanism by which value increases — memorise this, because it is the sharpest sentence in the chapter:
Notice that both halves are about the cash flow / risk pair. Nothing about price patterns. That is the whole difference.
The workbook adds a number here that is easy to miss: traders profit from price patterns and price anomalies which would be corrected within a period up to 3–6 months, with no change in the fundamental value of the asset.
Active and passive investing
Once you are an investor rather than a trader, there is a second fork.
Active investing means identifying the specific security or set of securities to buy or sell. It requires constant evaluation of every security in the portfolio — sell what is priced above intrinsic value, buy what is priced below intrinsic value. It needs more effort and a greater number of transactions. The objective: a rate of return above the return generated by the broader asset class.
Passive investing means buying a broad set of securities that fairly represent the asset class. Typically this is an indexing strategy — buy all the securities in an index. The passive investor does not decide upon individual securities; the analysis is limited to the broader asset class. The objective: the rate of return that the select asset class provides.
So the difference is not "cheap versus expensive". It is a difference in objective — beat the asset class, or receive the asset class.
4.2 What a research analyst actually does
The role has two parts, and the workbook separates them deliberately:
- Research — obtaining all the necessary information to meet a set goal, objective or research question.
- Analysis — analysing all the available information to arrive at a conclusion.
Research comes first. Analysis is worthless if the information underneath it is thin.
Why is it not enough to read the annual report? The workbook gives three reasons:
- An annual report needs very detailed scrutiny to yield real insight, and often the information in annual reports is not adequate.
- Annual reports are published once a year, so the information starts becoming dated with the passage of time.
- Industry conditions and the broader economy may not be covered in depth in the company's own filings.
So the analyst spends significant time on the economy, the industry and the company. That means secondary research — reports from market research firms, speaking to industry experts, tracking competitors' actions — and often primary research: visiting the company's facilities, speaking to customers, suppliers, employees and others.
The bright line: insider information versus mosaic analysis
Primary research walks you towards non-public information. The workbook draws the line very carefully.
Insider information is material non-public information that, when published, would immediately affect an investor's decision to buy or sell the security.
Whether a piece of information counts as insider information depends on three things:
- The source of the information — how reliable it is
- Its impact
- Its certainty
The workbook's own two examples:
- A CEO talking about an unpublished acquisition proposal — insider information.
- An employee talking about increasing workload in the purchase department (which may indicate higher business activity) — need not fall under insider information.
Mosaic analysis is what a good analyst does instead. Analysts collate information from different sources which individually may not be significant, but when put together with other public or non-public information may provide critical insight. The workbook is explicit: such mosaic analysis is acceptable.
The professional obligation is stated as a warning: analysts must be careful about whether an insight came from their mosaic analysis, or from being privy to a specific non-public price-sensitive information. And the underlying rule for the whole section: the research work of the analyst should not involve collating insider information.
4.3 Technical analysis in one page
Technical analysis begins from an assumption:
If everything is already in the price, then studying the company is redundant. What is left to study is the price itself. So technical analysis forecasts the direction of prices through the study of patterns in historical market data — price and volume. Its practitioners are technicians, sometimes called chartists.
The workbook names three essential elements in understanding price behaviour:
- The history of past prices — provides indications of the underlying trend and its direction.
- The volume of trading that accompanies price movements — provides inputs on the underlying strength of the trend.
- The time span over which price and volume carry the impact of long-term factors that influence prices.
These three are integrated into price charts, points of support and resistance, and price trends.
Support is a level with a lot of buying interest. Resistance is a level with a lot of selling interest. If a stock is moving closer to an established resistance level, a holder can benefit by booking profits, since prices are likely to retract. If a support or resistance is broken and accompanied by strong volumes, the trend has accelerated and the supply–demand situation has changed.
Volume is the confirmation tool. An upward or downward trend should be accompanied by strong volumes. A trend not supported by volumes indicates weakness in the trend.
Charts named in the workbook: line charts, bar charts, candlestick charts. And one specific technique: chartists use the moving average of the stock price to reduce the impact of day-to-day fluctuations that make the trend hard to see. That exact point is one of the workbook's own three sample questions.
Finally, the suitability rule:
- Short-term investors and traders largely rely on technical signals, because business fundamentals seldom change drastically in the short run.
- Technical analysis is less likely to be suitable for long-term investing, because business fundamentals may change in the long term — which makes the past trend in share price unreliable.
4.4 Fundamental analysis in one page
Fundamental analysis is the mirror image. It is focused on long-term investing.
Its premise: since equity shares reflect part ownership of a company, in the long term the value should be driven by the profits and cash flows generated by the company on its investments. When short-term price movement causes the price to significantly diverge from fair value, that divergence creates a profit-making opportunity.
The decision rule follows directly:
| Market price versus intrinsic value | Action |
|---|---|
| Market price below intrinsic value | Attractive investment opportunity — buy |
| Market price above intrinsic value | Sell the share, or avoid investing |
So profits come not only from identifying a good investment option, but also from making the investment at the right price. A great company at a stupid price is not a fundamental buy.
And here is a line that gets tested: this entire thought process is in contradiction of the Efficient Market Hypothesis (EMH), which holds that share prices incorporate and reflect all relevant information. If EMH were fully true, there would be no divergence to exploit and fundamental analysis would be pointless.
Fundamental analysis asks seven questions, and the workbook lists them in order:
- How is the overall cyclical and secular macro-economic trend, and will it help the industry grow or decline?
- How is the competition intensity within the industry, and is it conducive for existing players to thrive?
- How is the company positioned versus its competitors?
- What is the company's cost structure, and how will it affect profit under different business environments?
- How strong is the financial position — strong enough to fund growth or withstand crisis?
- What are the capabilities of the management — can they identify and execute the right strategies?
- Is the right governance structure present, so that the board and management act in the best interest of shareholders?
All seven fall into three baskets: 1. Economic analysis. 2. Industry analysis. 3. Company analysis. Those three baskets are Chapters 5, 6 and 7–8 of this workbook.
4.5 Quantitative research
Fundamental research involves both quantitative and qualitative studies. Some analysts go purely quantitative, and the workbook makes an important point: the quantitative approach can be used in both technical analysis and fundamental analysis.
- In technical analysis — instead of reading charts, the analyst studies the underlying data: the relationship between price up-moves and down-moves, volume and other parameters.
- In fundamental analysis — the analyst looks for finance and operational metrics of the company, in the hope that some metric, alone or combined, acts as a leading indicator of performance.
The toolkit runs from simple to sophisticated: time series analysis and regression of historical data to extrapolate future earnings; then econometric approaches; and alongside the statistics, financial statement analysis, projections of future financials and growth rates, sensitivity analysis and simulations to see how changed assumptions move the valuation.
Now the limitation — this is the workbook's own third sample question, so learn it verbatim:
Conclusion: pure quantitative research is not often employed in fundamental analysis.
4.6 The behavioural approach
Investment decisions must be based on analysis of available information, so that they reflect expected performance and risks. Very often they are not — they are influenced by behavioural biases of the decision maker, leading to less than optimal choices.
The behavioural school's assumption: securities' prices go away from their fair values, either upside or downside, because of the fear and greed of market participants. That is the whole premise, and notice it cuts both ways — mispricing is not only downside.
The workbook defers the list of biases to a later chapter. When you meet them there, the ones named are loss-aversion bias, confirmation bias, ownership bias (the endowment effect), gambler's fallacy, winner's curse, herd mentality, anchoring and projection bias.
4.7 Fundamental analysis of commodities
Commodity fundamentals are a different discipline. The workbook's definition:
It focuses on supply and demand factors, seasonality, macro-economic conditions, news, currency movement, interest rates, weather, inventory level, government intervention and so on.
Supply-side factors (4.7.1):
- Production — from farms, oil wells, mines
- Weather condition — floods, drought, cyclonic effect
- Government policies — tariffs, levies, trade restrictions and promotion, subsidies
- Geopolitical events — sanctions, wars, trade disputes
- Input costs — energy cost, input cost, wages, technology
Demand factors (4.7.2):
- Global economic growth — improvement in GDP creates additional demand for metals, energy and agri-products
- Population growth and urbanisation — increases food and energy consumption
- Substitution effect — switching between commodities
- Seasonal demand — higher fuel demand in winter/summer, festive food demand
- Consumer preferences — shift to organic foods, renewable energy, electric vehicles
Macroeconomic indicators (4.7.3):
- Inflation — commodities, especially gold and silver, act as an inflation hedge
- Interest rates — higher rates strengthen the USD, lowering commodity prices
- Trade balance and industrial data — Purchasing Managers' Index (PMI) and industrial production affect metals and energy demand
4.8 The workbook's two case studies
Gold
Uses: jewellery, industrial, investment, central bank reserves.
Gold is one of the largest traded commodities across the globe on commodity exchanges. It is an inflation hedge and a safe-haven asset because of its store of value. During economic turbulence, when equities, bonds and currencies underperform, investors turn to gold. Historically and statistically it is proved that gold carries an inverse relationship with stocks, bonds and currencies.
Demand by sector: Jewellery 47%, Investment 24%, Central Bank 23%, Technology 6%.
Major producers: China, Australia, Russia, USA, Canada. Major consumers: China, India, USA, Germany, Saudi Arabia.
What pushes gold up (and what pushes it down):
| Factor | Positive for gold | Negative for gold |
|---|---|---|
| Monetary policy | Expansionary (reducing interest rate) | Contracting (hiking interest rate) |
| U.S. Dollar | Weaker dollar | Stronger dollar |
| Economic data (GDP, labour, manufacturing, services) | Weaker economic data | Stronger economic data |
| Inflation | Higher inflation | Lower inflation |
| Supply | Lower supply | Higher supply |
| Demand | Stronger demand | Weaker demand |
| ETF | Buying | Selling |
| Central bank | Buying | Selling |
| Political | Unstable | Stable |
| Stock market | Bear stock market | Bull stock market |
| Bond market | Lower bond yields | Higher bond yields |
Gold is the anti-asset. Almost everything that is good news for the economy is bad news for gold.
Crude oil
Uses: fuel, polymers (plastic), lubricating oil, naphtha, bitumen.
Crude oil is called the mother of the global financial market and black gold, because of its importance to global economic growth. It is a naturally available, flammable liquid found in rock formations in the earth. Distilled at different temperatures it produces bitumen, lubricating oils, fuel oil, diesel, paraffin, naphtha and gasoline. It is the lifeline of the global economy, and any supply–demand imbalance results in inflationary concerns across the globe.
Quality of crude oil is based on two things: (1) density and (2) sulphur content.
| Benchmark | Where | API | Sulphur | Traded on |
|---|---|---|---|---|
| West Texas Intermediate (WTI) | Explored and physically traded in the United States | 39 | 0.24% | NYMEX |
| Brent | Pricing benchmark for Europe and Africa, from the North Sea, United Kingdom | 38 | 0.4% | ICE |
(The workbook prints those API figures as 390 and 380 — they are degrees API, 39° and 38°, with the degree sign lost in typesetting. What the exam can test is the pairing: WTI–0.24%–NYMEX and Brent–0.4%–ICE.)
Who controls supply: the United States and OPEC+, where OPEC+ = 13 OPEC members + Russia.
The four supply numbers to memorise:
- The Middle East has the majority of the world's oil reserves — 48% of all known and identified reserves
- OPEC owns almost 40% of the world's crude oil
- OPEC accounts for 75% of proven oil reserves
- OPEC exports 55% of the oil sold worldwide
Major producers: USA, Russia, Saudi Arabia, Canada, China. Major consumers: USA, China, India, Germany, Japan.
What pushes crude up (and what pushes it down):
| Factor | Positive for crude | Negative for crude |
|---|---|---|
| OPEC production | Production limits by OPEC group | Production rise by OPEC group |
| U.S. production | Fall in oil production | Rise in oil production |
| Oil rig count in U.S. | Fall in rig counts | Rise in rig counts |
| Inventory in the U.S. | Falling inventory | Rising inventory |
| U.S. Dollar | Weaker currency | Stronger currency |
| Economic data (GDP, industrial) | Expansion in the economy | Contraction in the economy |
| Political situation | Unstable, especially in the Middle East | Stable |
| Weather in the Gulf of Mexico | Extreme, especially hurricane season | Stable |
| Stock market | Bullish stock market | Bearish stock market |
Compare the last row against gold's last-but-two row and you have the single best trap in this chapter. A bullish stock market is positive for crude and negative for gold. Crude is a growth asset; gold is a fear asset.
4.9 Historical events
20 April 2020 — WTI goes negative. The workbook records that WTI crude oil prices fell into negative territory, and explains exactly why:
- The May contract was expiring the next day.
- There was no demand for crude across the globe, because 90% of the world was under lockdown to control the spread of coronavirus.
- WTI is a deliverable contract at Cushing, Oklahoma, and lockdown-induced restrictions on oil movement meant buyers of contracts were not ready to take delivery upon expiry.
- So buyers went on a selling spree that day, which resulted in negative pricing.
The lesson the workbook wants: a negative price is not a statement about the cost of producing oil. It is a statement about delivery obligation plus full storage plus an expiring contract.
1973 — the first oil crisis. Looking back at global oil crises, there are two major crises post World War II. The first happened in 1973, when members of OPEC decided to quadruple oil prices to almost $12 a barrel, and prohibited export of oil to the United States, Japan and western Europe, which together were consuming more than half of the world's oil.
4.10 Why a commodity move shows up in your equity screen
Commodity and equity markets carry a strong relationship, for a very ordinary reason: some of the companies listed on stock exchanges use commodities as raw material. So a price move directly impacts the profit margins of those companies, which in turn results in price movement of those stocks.
The rule, in the workbook's words:
- A rise in commodity prices increases input costs, which reduces profit margins of companies.
- Conversely, falling commodity prices can improve profitability and boost stock valuations.
But it is not one-directional across the market, and the workbook's own example proves it: rising crude oil prices improve the profitability of oil producing companies and at the same time reduce the profitability of airline and logistics companies, because of the high input cost. Same commodity, opposite effect, depending on whether the company sells it or buys it.
There is a second channel too, which is about information rather than margins. Commodities are globally traded, so changes in crude, gold or copper prices often signal shifts in global demand and supply. Equity markets, being sensitive to growth prospects, react to these signals. The workbook's example: a fall in copper prices may signal slowing industrial demand, dragging down metal and infrastructure stocks.
That is two distinct mechanisms — the cost channel (margins) and the signal channel (what the price tells you about global demand). Questions can test either.
Think of it like this
The onion trader and the onion farmer
Two people at the Lasalgaon mandi are both making money from onions.
The trader buys 50 quintals at ₹1,400 in the morning because he has watched this market for years and knows the price usually firms up by afternoon. He sells at ₹1,460 and goes home. Nothing about the onions changed. He earned the spread.
The farmer plants a better seed variety, installs drip irrigation and signs a supply contract with a food processor. His field will yield more, more reliably, for the next several seasons. The land is worth more now — not because the price moved today, but because the cash flow went up without a proportionate rise in risk.
That is the workbook's exact test for investing. Ask of any decision: is the person betting the price will move, or that the cash flow or risk has changed? The first is trading. The second is investing.
Reading the platform, not the timetable
Stand on a Mumbai local platform at 6 pm. You want to know whether the next train will be crowded.
One way: look at the timetable and the office holiday calendar — work out how many people are travelling and why. That is fundamental analysis. It takes effort, it works over long stretches, and it tells you something the platform cannot.
The other way: look at how thick the crowd already is, and how fast it is thickening. That is technical analysis — price is the crowd, volume is the rate of thickening. It assumes the crowd already knows everything the timetable knows, because everyone on the platform read it before coming.
The assumption is the whole thing. Technical analysis says all information is already reflected in the price, so there is nothing left to read but the price. And it explains why technical works for the next train but not the next decade — the crowd size tells you nothing about whether the railway will electrify the line in five years.
The rangoli of chalk dots
A rangoli is made of hundreds of individual chalk dots. Look at one dot and you learn nothing. Stand back and a peacock appears.
Mosaic analysis is exactly that. The analyst hears from a supplier that orders are up. She notices the company's job postings mention a second shift. A dealer mentions inventory is moving fast. No single dot is material. Assembled, they say the quarter is going well. The workbook says this is acceptable.
Now contrast: the CEO tells her about an unpublished acquisition proposal. That is not a dot. That is somebody handing her the finished picture. It is material non-public information that, if published, would immediately change a buy or sell decision — the definition of insider information.
The test the workbook gives has three parts — source, impact, certainty. A reliable source, a large impact, and high certainty means you are holding the picture, not a dot. That is when you stop.
The godown is full and the truck cannot move
Imagine a cold storage near Nashik in April 2020. It is full of onions. The lockdown means no trucks. A farmer has a contract to deliver 100 quintals tomorrow and there is physically nowhere to put them. What will he pay someone to take the delivery off his hands? Quite a lot, actually — more than the onions are worth — because the alternative is a legal obligation he cannot discharge.
That is precisely the 20 April 2020 WTI story. WTI is a deliverable contract at Cushing, Oklahoma. The May contract expired the next day. With 90% of the world under lockdown, there was no demand and no way to move oil. Contract holders were not ready to take delivery, so they sold at any price — and the price went negative.
The mechanism to carry into the exam: negative pricing came from delivery obligation + no storage + imminent expiry, not from the cost of producing oil.
The tomato price cuts both ways
When tomatoes go to ₹120 a kilo, two Indian businesses react in opposite directions. The farmer in Kolar has the best season of his life. The Udupi restaurant in Bengaluru watches its margin evaporate, because tomatoes are an input it must buy.
Same commodity. Same price move. Opposite effect on profit — and therefore opposite effect on what each business is worth.
The workbook uses crude oil for the same point: rising crude improves the profitability of oil producing companies and simultaneously reduces the profitability of airline and logistics companies. So the exam question is never "is a crude rally good or bad for equities?" — it is "good or bad for which company?" Always ask whether the company sells the commodity or buys it.
