Building Your Personal Research Library

Lesson 111.1 — Why Every Serious Investor Needs a Library

Prakash Adhikari runs a small pharmacy called Adhikari Health Pharmacy in Chipledhunga, Pokhara. He has sold cough syrup and blood pressure tablets for over twenty years. But every Saturday morning, after the shop opens and the first rush of customers has passed, he sits at the small table behind the counter with a cup of milk tea and reads. Not medical journals. Annual reports of companies listed on the Nepal Stock Exchange, or NEPSE.

Prakash has been investing in NEPSE-listed shares since 2003. He is not a stockbroker, not an economist, not a chartered accountant. He is a pharmacist who treats investing as a serious hobby. Over more than two decades, he has built something that most Nepali investors never build: a personal research library. It is not a website. It is not a folder of downloaded PDF files sitting forgotten on a laptop. It is a living, growing, organised collection of documents, notes, and observations that he has curated with his own hands, year after year.

This chapter is about building that same kind of library for yourself.

Before we go further, we must be clear about one distinction, because readers of this book will remember Chapter 105, "The Canon Data Pipeline." That chapter taught you how to pull raw data from NEPSE — daily prices, trading volumes, floorsheets — and store it in a structured, repeatable way, almost like setting up plumbing so that clean water reaches your tap every day. That was about data flowing in continuously, in numbers.

This chapter is different. This chapter is about something slower, older, and in some ways more valuable: the accumulation of knowledge over years. Annual reports. Research notes written by brokerage analysts. Sector studies. Your own handwritten or typed observations about a company you have followed for a decade. This is not water flowing through a pipe. This is water stored carefully in a large clay pot, or "gagri," so that it is there for you months or years later when you need it, when the taps run dry, when nobody else remembers what happened the last time hydropower stocks crashed or the last time a microfinance company's board was reshuffled.

Why does this matter so much in the Nepali context specifically? Because our capital market is still young, our public information systems are still incomplete, and our institutional memory is short. NEPSE itself was established in 1993 with trading beginning in 1994. That is little more than three decades of market history. Many company websites do not keep old annual reports available for download. The Securities Board of Nepal, or SEBON, and NEPSE both publish disclosures, but these disclosures are often scattered, not compiled, and can disappear from a website when it is redesigned. If you do not save a document yourself, the assumption that "it will always be online somewhere" is dangerous. Many investors have discovered, to their frustration, that a five-year-old annual report they need for a comparison is now nowhere to be found, because the company's website only keeps the last two years posted.

There is a second reason a personal library matters, and it has to do with how understanding actually develops in a person's mind. Reading one annual report tells you what a company looked like in one year. Reading the same company's annual reports for ten years in a row, side by side, tells you a story — how its profits grew or shrank, how its dividend policy changed, how management explained good years and bad years differently, whether promises made in one year's report were kept by the following year. This kind of pattern recognition cannot happen if each year's document is read once and thrown away. It requires that the documents sit together, on a shelf or in a folder, waiting to be compared.

Think of it like a family that keeps old photographs. A single photograph of a child tells you almost nothing about how that child is growing. But an album with a photograph taken every year on the same date tells you a rich story of growth, health, and change. Your research library is that photograph album, except the subject is a company, a sector, or the whole Nepali economy.

Prakash's own path illustrates the payoff clearly. In 2015, he had been reading annual reports of Nepali hydropower companies for about four years. He had a habit: every year, when a hydropower company released its annual report, he would write, on the first page of his notebook entry for that company, three numbers in large digits — installed capacity in megawatts, actual electricity generated that year in units, and the ratio between the two, which tells you how efficiently the plant actually ran compared to its theoretical maximum. Most investors look only at profit. Prakash looked at this ratio, called the plant load factor or capacity utilisation, because his training as a pharmacist had taught him to think in terms of dosage delivered versus dosage prescribed — the difference between what should happen and what actually happens.

By 2015, he had four years of this ratio recorded for a mid-sized hydropower company he was following. He noticed the ratio was falling steadily, year after year, even though the company's reports always mentioned "normal operations" in the chairman's message. A single year's report would not have shown this. Four years side by side did. He sold his position before the company later disclosed serious turbine wear issues and a costly repair that hurt two years of dividends. He did not predict the mechanical failure. He noticed a trend that management's cheerful language was not fully explaining, and his notebook made that trend visible to him in a way that memory alone never could have.

This is what a research library is for. It does not predict the future. It preserves the past accurately enough that patterns become visible, and it forces you to write down, in your own words, what you understood at the time — which is often more valuable later than what you remember feeling.

Lesson 111.2 — The Five Pillars: What Belongs in Your Library

A common mistake among new investors is trying to collect everything. This leads to a library that is really just a digital junk drawer — hundreds of PDF files with confusing names, never organised, never reviewed. A useful library is built from a small number of clearly defined categories, collected consistently, not a chaotic pile of everything you happened to download.

We recommend organising around five pillars.

The first pillar is annual reports. Every company listed on NEPSE is required to publish an annual report, which includes audited financial statements, the board of directors' message to shareholders, an auditor's report, and disclosures about related-party transactions, risk factors, and corporate governance compliance. This is the single most important document type for long-term investors, because it is the one document a company is legally required to produce carefully, get audited, and present to its own owners — the shareholders. Annual reports are usually available from the company's own website, from NEPSE's corporate disclosure section, and sometimes are handed out physically at the company's Annual General Meeting, commonly called the AGM.

The second pillar is brokerage and analyst research notes. Nepali stockbrokers, and a small number of independent research firms, occasionally publish notes on specific companies or sectors — for example, a note comparing the profitability of the major commercial banks, or an assessment of a hydropower company ahead of a rights share issue. These notes are not neutral; the brokerage may have a business relationship with the company it is writing about. But even a biased note contains useful raw material: numbers, comparisons, and industry context that took someone else time to compile. Read them critically, but do not discard them.

The third pillar is sector reports and regulatory publications. Nepal Rastra Bank, our central bank often called NRB, publishes regular reports on the banking and financial sector, including its "Financial Stability Report" and "Monetary Policy" statements, which affect interest rates and therefore the profitability of banks and finance companies. SEBON publishes an annual report on capital market conditions. The Insurance Board, sometimes called Beema Samiti, publishes data on the insurance sector. Nepal Electricity Authority, or NEA, publishes data relevant to hydropower. These publications rarely mention specific companies but tell you about the "weather" the whole sector is operating in.

The fourth pillar is news and disclosure archives — clippings and saved articles about specific events: a bonus share announcement, a merger, a change in company leadership, a regulatory penalty, a new branch opening. A single newspaper clipping means little. A folder of clippings collected over five years about the same company, in chronological order, becomes a timeline of the company's real behaviour, distinct from what its own annual report chooses to emphasise.

The fifth pillar, and in some ways the most important, is your own personal notes — your own conclusions, questions, doubts, and predictions, written in your own words, dated, and never edited afterward to make yourself look smarter in hindsight. This pillar is what turns a pile of other people's documents into your library, because it records your thinking, not just other people's.

A word of caution about the fourth pillar, news clippings. Nepali financial journalism, like financial journalism everywhere, sometimes repeats a company's own press release without independent checking. A news clipping tells you what was reported, not necessarily what was true. Keep clippings, but label them clearly as "reported claim," and check them later against the annual report or regulatory filing when one becomes available. Do not let a hopeful newspaper headline substitute for an audited number.

Lesson 111.3 — Choosing Your System: Physical Shelf, Digital Folder, or Both

Once you know what to collect, you must decide how to store it so that you can actually find it again three years later. There is no single correct answer — what matters is consistency, not sophistication. A simple system followed faithfully for ten years beats an elaborate system abandoned after three months.

Prakash uses a hybrid system, and it is worth describing in detail because it works well for someone without a technical background.

For physical documents — printed annual reports he receives at AGMs, or documents he prints because he finds reading on paper easier for long financial statements — he uses ordinary lever-arch box files, the kind sold in any stationery shop in Pokhara's New Road area. He keeps one box file per sector: one for commercial banks, one for hydropower, one for microfinance institutions, one for insurance, one labelled "others" for manufacturing, hotels, and everything else. Inside each box file, he uses cardboard dividers with a company's short stock symbol written on top in thick marker — for example, "NABIL" for Nabil Bank, or "UPPER" for Upper Tamakoshi Hydropower. Within each company's section, documents are simply stacked with the newest year on top. This is the entire physical system: sector box, company divider, newest on top. No further complexity.

For digital documents — PDFs downloaded from company websites, brokerage notes received by email, regulator reports downloaded from NRB or SEBON websites — he keeps a folder structure on his laptop that mirrors the physical system exactly. A top-level folder called "NEPSE Library," inside it sector folders with the same names as his physical box files, inside each sector folder a folder per company named with the stock symbol, and inside each company folder, files named with a strict pattern: year, then document type, then a short description. For example, "2081_AnnualReport_UpperTamakoshi.pdf" or "2080_BrokerNote_NIC_Asia_Q3Review.pdf." He backs this folder up twice a year onto a small external hard drive, and once a year he emails a compressed copy to himself so that a copy exists outside his own house.

The mirroring between physical and digital matters more than either system alone. When Prakash wants to check something about a hydropower company while travelling, he can search his laptop folder. When he wants to sit down for a serious Saturday reading session, he prefers the physical box file, because he finds that flipping pages by hand and writing in the margins with a pencil helps him think more slowly and carefully than scrolling a screen. Both systems serve him; neither replaces the other.

You do not need to copy this exact structure. What matters is answering three questions clearly, before you save anything:

First, how will documents be grouped — by sector, by company, by year, or by document type? Choose one primary grouping and stick to it; you can always search within a group, but you cannot easily search across an inconsistent grouping.

Second, how will files be named or labelled so that their contents are obvious without opening them? A name like "Scan001.pdf" is useless a year later. A name like "2081_AnnualReport_NIMB.pdf" tells you everything at a glance.

Third, where does the backup copy live, and how often is it refreshed? A library that exists only on one laptop, with no backup, is one hard drive failure away from being permanently lost. This has happened to real investors in Nepal — years of collected annual reports gone because a laptop was stolen or a hard drive failed, with no second copy anywhere.

For readers who prefer an entirely digital approach with no physical filing at all, the same three principles apply. Cloud storage services accessible from Nepal, simple note-taking applications, or even a well-organised set of folders synced across a phone and a laptop, all work fine. The technology matters far less than the discipline of consistent naming, consistent grouping, and consistent backup.

Lesson 111.4 — The Company Dossier: One File, Many Years

The single most powerful unit inside your research library is what we will call the company dossier — a single running file, physical or digital, dedicated to one company, that you add to every single year for as long as you hold, or are considering holding, that company's shares.

Think of the company dossier the way a family doctor keeps a patient's file. A doctor does not throw away last year's blood test results just because a new one has arrived. The old results, placed next to the new ones, reveal trends — is blood pressure rising over five years, is weight increasing steadily, is a particular medicine working. A single visit's numbers, without history, tell the doctor much less than the same numbers seen against the pattern of the last several years. Your company dossier does the same job for a business.

A well-built company dossier for a NEPSE-listed company should contain, in this order: the company's basic profile — when it was established, when it listed on NEPSE, its paid-up capital history, and its sector; then, year by year, its annual report, or at minimum its audited financial highlights if the full report is unavailable; then a simple table you maintain yourself, tracking the same handful of numbers every single year so they can be compared at a glance; and finally, your own dated notes, written after each year's reading, recording what surprised you, what confirmed your earlier view, and what you plan to watch for next year.

The self-maintained table is worth describing carefully, because it is the heart of the dossier. Choose a small number of figures — five to eight is usually enough — that matter most for that company's sector, and track exactly the same figures every year without changing your mind about what to track. For a commercial bank, useful figures might include net profit, distributable profit, net interest margin, non-performing loan ratio, capital adequacy ratio, and dividend percentage declared. For a hydropower company, useful figures might include installed capacity, actual units generated, plant load factor, and interest coverage ratio, since hydropower companies typically carry significant debt during construction and early operation. For a microfinance institution, useful figures might include loan portfolio size, portfolio at risk, and the interest rate spread it earns between what it charges borrowers and what it pays depositors.

Here is a case that shows the value of this discipline concretely. A retired schoolteacher in Biratnagar, whom Prakash corresponds with occasionally through an investors' discussion group, held shares in a small finance company for six years without any dossier at all — she simply kept the share certificates and checked the share price occasionally. When the company's share price fell sharply after a disappointing year, she had no record to consult about whether this was a one-year problem or the continuation of a longer decline, because she had never written down the company's numbers from earlier years. She had to guess, under the stress of a falling price, whether to sell or hold — exactly the wrong moment to be reconstructing history from memory. Prakash, who did maintain such tables for the companies he owned, was able to look back at his own hydropower dossier during a similar price fall and confirm calmly that the underlying generation numbers were still healthy, that the price fall was driven by general market sentiment rather than company-specific trouble, and he held his position, which recovered within a year.

Building a company dossier requires patience. You cannot build ten years of history in one afternoon; you build it one year at a time, starting today, with whatever historical annual reports you can still find for past years, and continuing forward faithfully every year after that. A dossier started today, for a company you plan to hold for fifteen years, will be extraordinarily valuable by year ten — but only if you actually keep adding to it every single year, including the boring years when nothing dramatic happened. The boring years matter too, because they establish the normal pattern against which a genuinely unusual year can be recognised.

We recommend maintaining full dossiers for no more than fifteen to twenty companies at a time — the companies you actually own, or are seriously studying for a possible future purchase. Trying to maintain deep dossiers on every one of the roughly two hundred fifty companies listed on NEPSE is not realistic for an individual investor with a full-time job or business, and it dilutes the depth of attention any single dossier receives. Depth on a smaller number of companies beats shallow coverage of everything.

Lesson 111.5 — Building Sector Knowledge, Not Just Company Knowledge

A library built only from individual company dossiers has a blind spot: it cannot easily tell you whether a company is doing well because of its own management decisions, or simply because its entire sector is having a good year, or a bad one, for reasons outside any single company's control. To catch this, your library needs a second layer, organised by sector rather than by company.

Consider commercial banks. Nepal's commercial banks, sometimes called "A class" banks under Nepal Rastra Bank's licensing categories, are all affected together by NRB's monetary policy decisions — changes to the cash reserve ratio, the statutory liquidity ratio, and policy interest rates. When NRB tightens monetary policy to control inflation, loan growth typically slows across all banks simultaneously, and interest spreads may compress. If you only track individual bank dossiers, you might wrongly conclude that a particular bank's slower profit growth reflects poor management, when in fact every bank in the sector experienced the same slowdown that year. Only a sector-level view, tracking industry-wide figures over time, lets you correctly separate "this bank underperformed its peers" from "the whole sector faced a difficult year."

The same logic applies powerfully to hydropower. Nepal's hydropower generation depends heavily on river flow, which varies by season — the monsoon months from roughly June to September bring high water flow and high generation, while the dry winter and spring months bring much lower flow and lower generation for run-of-river plants, which make up most of Nepal's listed hydropower companies. A single hydropower company's weak quarter might simply reflect a dry season common to the entire sector, not a company-specific problem. Keeping a sector-level folder with data on national hydropower generation trends, rainfall patterns, and NEA purchase agreements lets you judge each company's own report against a realistic sector backdrop, rather than in isolation.

For microfinance institutions, sector-wide knowledge about loan portfolio quality across the whole industry, and about NRB's evolving regulations for microfinance mergers and capital requirements, similarly helps you judge whether one institution's rising bad loans reflect its own weak lending discipline or an industry-wide stress affecting all microfinance lenders at once — which has, in fact, happened in Nepal in certain years when overall microfinance sector loan quality weakened broadly.

Building sector knowledge in your library does not require separate elaborate research. It simply requires that, alongside your company dossiers, you keep a small number of sector-level documents each year: the relevant regulator's annual or periodic report, a short note you write yourself summarising what changed in the sector's operating environment that year, and any brokerage sector comparison notes you come across. Over time, this sector folder becomes a second, complementary photograph album — this time of an entire industry's health, rather than one company's.

Prakash keeps exactly this kind of sector folder for hydropower, and it proved useful in 2021, when several hydropower companies simultaneously reported weaker-than-expected quarterly generation. A less experienced investor, checking only individual company dossiers, might have panicked and sold across the board, assuming something specifically wrong at each company. Prakash's sector folder contained rainfall and river flow data he had been tracking, which showed a genuinely unusual dry spell affecting the whole Gandaki and Koshi river basins that year. He correctly attributed the weak quarter to weather, not mismanagement, held his hydropower positions, and watched generation numbers recover to normal the following wet season as his sector-level data had suggested they would.

It is worth adding a caution here about comparing companies within a sector using numbers alone, without understanding differences in accounting choices or business models. Two hydropower companies may both report "installed capacity," but one may be a purely run-of-river project with large seasonal swings in generation, while another may have limited storage capability that smooths out some of that seasonal variation. Comparing their generation figures directly, without noting this structural difference, can lead to unfair conclusions about which company is "better run." Your sector notes should record these structural differences once, clearly, so you do not have to relearn them every time you make a comparison.

Lesson 111.6 — Maintaining the Library for the Long Run

A library that is built once and never tended will slowly become useless — not because the old documents lose their value, but because without regular maintenance, new documents stop being added consistently, the filing system drifts into inconsistency, and eventually you stop trusting the library enough to actually use it when making decisions. Maintenance is not a separate chore from research; it is the research habit itself, repeated.

We recommend three simple maintenance rituals, each performed at a different frequency.

The first ritual is a weekly or monthly filing session — a fixed time, ideally the same day each week or month, set aside purely for filing new documents that have accumulated: sorting downloaded PDFs into the correct folders, filing away printed documents into the correct box file section, and clearing your desk or downloads folder of anything not yet filed. Prakash does this every Saturday morning, which is also when he does his main reading, so filing and reading happen together as one habit rather than two separate chores competing for his time.

The second ritual is an annual review, ideally done around the Nepali new year or around the time most companies hold their AGMs, when a natural wave of new annual reports arrives. During this annual review, go through each active company dossier and ask three questions: did this company's numbers move in the direction I expected last year, did anything happen that changes my view of its management's honesty or competence, and is this still a company worth tracking closely, or should its dossier be moved to an inactive or "watch occasionally" section. This annual review is also the right moment to update your sector notes, and to check whether your regulatory reference documents — NRB directives, SEBON rules — are still current, since these do get revised periodically.

The third ritual, less frequent but important, is periodic weeding — perhaps once every three to five years, going through your library and asking honestly whether it has become cluttered with material you never actually use: brokerage notes for companies you sold years ago and have no interest in revisiting, duplicate downloads, or news clippings about rumours that never materialised into anything. Weeding is not about discarding history casually — annual reports and your own dated notes should almost never be deleted, since they are the permanent record that gives the library its value over decades. Weeding is about clearing away the noise that accumulates around that permanent record, so the important material remains easy to find.

There is one more dimension to long-term maintenance worth discussing: what happens to your library as time passes and your own life circumstances change. A library built carefully over twenty years is not just a personal tool; for a family, it can become a kind of inherited financial wisdom, similar to how households in Nepal often pass down knowledge about land, gold, or family businesses from one generation to the next. Prakash has begun involving his daughter, who is studying commerce at a college in Pokhara, in his Saturday filing sessions, explaining to her why each document matters and how to read the tables he has built. This is not sentimental; it is practical. A well-organised library that only its creator understands is fragile — if that person becomes unavailable, through illness, travel, or simply old age, decades of careful work can become an incomprehensible pile of paper to anyone else. Writing clear notes, in plain language, and occasionally explaining your system to someone else, protects the value of everything you have built.

Finally, remember why you are building this library at all. It is not a collection for its own sake, and it is not meant to impress anyone. Its entire purpose is to make your future investment decisions better informed than they would be from memory alone, and to let patterns become visible across years that no single year's document could reveal. Every annual report filed, every dossier table updated, every dated note written down honestly, is a small deposit into a resource that compounds in value the way a disciplined investment portfolio compounds in value — slowly, quietly, and then, after enough years, quite powerfully. Prakash's decision to sell his weakening hydropower holding in 2015, and his decision to hold calmly through the sector-wide dry spell of 2021, both came from the same source: years of unglamorous, consistent filing and note-writing, paying off exactly when it mattered most.
