NISM XV Case Studies and Negative Marking: How to Attempt the 2026 Paper

The NISM XV Research Analyst exam now has 5 case studies of 4 questions each, worth 20 marks out of 100. This pattern has applied since 20 January 2026, and the other 80 marks come from one-mark MCQs. A wrong answer costs 0.25 marks, while a question you leave blank costs nothing. So clearing NISM 15 depends on knowing when to answer as much as knowing the syllabus. Most numerical case studies come from Financial Analysis, Valuation and Technical Analysis. In this guide, Prof. Sheetal Kunder shares how she teaches students to read a case, when to attempt or skip a question, and why Chapter 14 matters long after the exam.

How the NISM XV Case Studies Have Changed

When I appeared for the NISM XV exam in 2016, it was a 100-mark paper with 25% negative marking and no case studies at all.

NISM later added two case studies worth 4 marks each, but since they carried only 8 marks, many candidates chose to skip them and focus on the 92 marks of regular MCQs.

That approach no longer works. Since 20 January 2026, the paper includes 5 case studies of 4 questions each, which means 20 marks now depend on how well you can apply what you have learnt.

If you skip them, you need 60 out of the remaining 80 MCQ marks to pass, and with negative marking on every wrong answer, that leaves very little room for error.

In other words, case studies have moved from being optional to being essential for clearing the exam.

Are Numericals Still Important in NISM XV?

Yes, very much. In my experience, numericals still make up around 20 questions in the paper, and the only real difference is that many of them now appear within the case studies instead of as standalone MCQs.

Most numerical case studies come from three chapters:

  • Chapter 8, Company Analysis: Financial Analysis: Ratios, profitability and reading financial statements

  • Chapter 10, Valuation Principles: P/E, discounting and valuation models

  • Chapter 15, Technical Analysis: Indicators, moving averages and chart reading

The addition of a 15-mark Technical Analysis chapter and a 5-mark commodities chapter also shows that NISM now expects a Research Analyst to understand traders as well as long-term investors.

So keep practising your calculations, but practise them the way the exam presents them:

  • Solve complete cases, not isolated questions: In a case study, each answer usually builds on the previous one, so a single early mistake can cost you all four marks.

  • Read the full case before you start: Note the key figures first, so you don't have to search for them while calculating.

  • Double-check your first calculation: Since every later answer depends on it, a quick recheck here saves the most marks.

Why NISM XV Case Studies Test You Like a Real Research Analyst

A Research Analyst's work goes beyond recalling formulas. In practice, you have to:

  • Study the economy, industry and company together

  • Analyse the financials and read the charts

  • Assess the risks and explain a reasoned opinion to your client

Imagine a client invests ₹25 lakh on your recommendation, money that may be their life savings or their child's education fund.

Knowing what a P/E ratio means won't be enough; you must judge whether the valuation makes sense, what the risks are and what evidence supports your call.

That is exactly what a case study tests. It puts you in the analyst's chair with real data and asks for a sound conclusion, because NISM wants to see whether you can think like a Research Analyst, not how much you have memorised.

How Negative Marking Works in NISM XV (With Example)

NISM deducts 25% of a question's marks for each wrong answer, so a wrong answer on a 1-mark question costs 0.25.

Outcome Marks
Correct answer +1
Wrong answer −0.25
Not attempted 0

Take a simple example. If you answer 99 questions correctly and leave one blank, you score 99, but if you attempt all 100 and get one wrong, your score comes down to 98.75.

One wrong answer costs only a quarter mark, but every careless guess chips away at your score, and over a full paper those small losses can matter.

In my classes, students from MBA, CA, CS, CFA and engineering backgrounds who clear the exam in their first attempt are usually the ones who understand this calculation well.

Should You Attempt or Skip a Question in NISM XV?

This is the rule I give my students. It is my own approach, not a NISM rule.

Situation What to do
You know the answer Attempt it
You can eliminate two options and reason between the rest Attempt it; that is analysis, not guessing
You have no idea at all Leave it and move on

The middle row is where most marks are won or lost, because even when you don't remember the answer straight away, you can often rule out two options with what you've studied and pick the better of the two that remain.

That isn't guessing but reasoning, and it's exactly what the exam is designed to reward.

How to Attempt the NISM XV Paper on Exam Day

From my teaching experience, I look at any professional exam paper as roughly 20% easy, 60% moderate and 20% challenging. This is a way of thinking, not a NISM formula.

  • Easy questions: Are your scoring area, so answer them carefully and don't lose marks to haste.

  • Moderate questions: Test conceptual clarity and application, which is where steady preparation pays off.

  • Challenging questions: Are not all out of reach. If you have practised calculations, solved case studies and revised properly, some of them will be solvable.

Go in to maximise correct answers and minimise avoidable mistakes, not to score 100.

If a question unsettles you, leave it and move on, because the next few questions may be ones you know well, and you can always come back to it later if time allows.

Remember that your goal is to cross 60 with a comfortable margin, not to answer every single question.

Chapter 14, Legal and Regulatory Environment, carries 10 marks, but I always tell my students not to treat it as just another theory chapter to finish before the exam. This is the chapter you will use every day once you become a SEBI-registered Research Analyst, because it explains your role, your responsibilities and what you can and cannot do, both before and after registration.

The chapter covers areas such as:

  • RA registration, qualification and certification requirements

  • client management and the Investor Charter

  • record maintenance and cybersecurity

  • periodic reporting, the annual audit and other compliance duties

Even if you appoint a compliance officer or outsource this work, you should still understand these requirements yourself. You may not handle every task personally, but knowing what needs to be done and when helps you stay in control and make sure nothing important is missed.

Since Chapter 14 questions are often precisely worded, it helps to practise them under exam conditions.

Our NISM XV Research Analyst Mock Test lets you do that with case studies and negative marking included, so you can spot your weak areas well before the real exam.

How to Prepare for NISM XV Case Studies and Clear in the First Attempt

  • Practise full cases, not single questions: Case questions build on each other, so one early error carries through all four.

  • Read the whole case once before answering: Note the key figures first, then solve in order.

  • Mix fundamental and technical cases: Expect cases from Chapters 8, 10 and 15.

  • Score your mocks with negative marking: Use +1, −0.25 and 0, so your practice score matches the real exam.

  • Book only when you are ready: If you are preparing with mock tests, aim to score above 90% consistently before you book your slot.

When you feel ready to test yourself under real exam conditions, try our NISM XV Research Analyst Mock Test, which follows the 2026 pattern with case studies and negative marking.

Conclusion

The revised NISM XV exam is designed to test how well you can apply concepts, not how much you can recall.

With 5 case studies now worth 20 marks, and many numericals from Chapters 8, 10 and 15 built into them, the case-study section can easily decide your result, so it deserves serious practice from the start.

On exam day, keep your approach simple: attempt the questions you know, attempt the ones you can reason through, and leave the ones where you would only be guessing.

Give Chapter 14 the attention it deserves too, because it will guide your work long after the exam is over.

I don't believe the NISM Research Analyst exam is very difficult, but it is certainly challenging. Since you can choose your own exam date, prepare thoroughly first and book your slot only when your mock test scores are consistently strong.
