AIS
Regulation & taxAlso called: Annual Information Statement
The Annual Information Statement on the income tax portal, listing the transactions the department already holds on record — share sales reported by your broker, dividends and interest received.
In plain terms
Read it before you file rather than after. A mismatch is the commonest trigger for a notice, and it is almost always clerical: an account you forgot about, or a corporate action recorded differently.
Read the full lesson →Material event
Regulation & taxAlso called: Materiality policy, Material information
An event a listed company must disclose to the exchanges — either deemed material by the regulations, or material on applying the quantitative thresholds in its own published policy.
In plain terms
Two kinds. Some events are material by definition and the company has no say. Others are tested against a threshold the company must publish, so you can read where it drew its line.
Read the full lesson →Unpublished price sensitive information
Regulation & taxAlso called: UPSI, Insider information
Non-public information that would affect a security’s price if known.
In plain terms
Trading while in possession of it is an offence regardless of how you obtained it.
Read the full lesson →Credit information report
Regulation & taxAlso called: Credit report
The record a credit information company holds of your borrowing, carrying a month-by-month payment status for each account and retained for a period the regulations cap.
In plain terms
Every entry is reported by the lender, not by you — so correcting one means getting the lender to report something different, not arguing with the bureau.
Read the full lesson →Information asymmetry
Technical analysisSome participants knowing more than others.
In plain terms
On a news day thousands are reading the same headline and almost nobody has read the filing.
Read the full lesson →Restated financial information
AccountingAlso called: Restated accounts, Restated financials
Financial statements in an offer document recast onto a single consistent accounting basis across the periods presented, and reported on by the auditors.
In plain terms
Built for comparability rather than for the original year’s reporting. It lets you set a rival’s margins and working capital beside a listed company on a like basis.
Read the full lesson →Accumulation
Technical analysisSustained buying by informed participants, usually visible as heavy volume without much price progress.
In plain terms
Big money buying quietly, because buying loudly would move the price against them.
Read the full lesson →Analysis paralysis
Risk & psychologyDelaying a decision indefinitely by continuing to gather information.
In plain terms
Research feels productive and carries no risk of being wrong, which is exactly what makes it such an effective way of not starting.
Read the full lesson →Arbitral award
Regulation & taxAlso called: Arbitration award
The decision of an arbitral tribunal, enforceable as a decree once the grounds for challenging it are exhausted.
In plain terms
A change in probability, not a receipt. It can be challenged in court, a public-sector counterparty frequently will, and the money can be years behind the announcement.
Read the full lesson →CIBIL
Market basicsOne of India’s credit information bureaus, whose score is widely quoted.
In plain terms
You are entitled to a free report each year. Check the report, not just the number — errors are common.
Read the full lesson →Composite operator
Technical analysisWyckoff's device of reading all large, informed buying and selling in a stock as though it were the work of one deliberate operator.
In plain terms
A useful fiction, because the constraint underneath it is real: size cannot be accumulated quickly, so it has to happen slowly and leaves a signature.
Read the full lesson →Confirmation bias
Risk & psychologySeeking and favouring information that supports an existing belief.
In plain terms
Stock-tip groups are confirmation machines — everyone in them already owns it.
Read the full lesson →Credit bureau dispute
Regulation & taxThe process for correcting a wrong entry in a credit information report, under which the lender is asked to verify and the regulator has set periods for resolution.
In plain terms
It fixes a wrong entry, not a correct entry you dislike. The bureau reports what the lender supplies, so a real dispute is won against the lender.
Read the full lesson →Days past due
Regulation & taxAlso called: DPD
The number of days an instalment or amount has remained unpaid, counted from the due date the lender fixed and reported month by month to the credit information companies.
In plain terms
The count runs from the due date, not from the day anybody telephoned you, and it does not reset because later instalments are being paid.
Read the full lesson →Debts Recovery Tribunal
Regulation & taxAlso called: DRT
The forum that hears challenges to enforcement measures taken under the security enforcement law, and lenders' own recovery proceedings above a threshold. Civil courts are barred from these matters.
In plain terms
The first application there matters far more than the appeal, because an appeal beyond it requires depositing a large part of the claimed debt before it will be heard.
Read the full lesson →Demand notice
Regulation & taxThe first step in enforcing a security interest — a notice calling on the borrower to discharge the full liability within sixty days, after which the lender may take possession.
In plain terms
It demands the entire recalled debt, not the instalments that were missed. Clearing the arrear is worth doing and does not by itself answer the notice.
Read the full lesson →Disclosure
AccountingInformation a company is required to publish about its position and transactions.
In plain terms
Most problems are disclosed long before they are priced. The constraint is reading, not access.
Read the full lesson →Disconfirming evidence
Risk & psychologyInformation that contradicts an existing belief or thesis.
In plain terms
A falling price is not disconfirming evidence. Deteriorating fundamentals are.
Read the full lesson →Efficient market
Technical analysisThe claim that prices already reflect available information, so no repeatable pattern in past prices can be exploited.
In plain terms
The strongest objection to technical analysis, and it holds in part: simple published systems do decay once everyone can see them. What does not get arbitraged away is the discipline to follow a rule consistently.
Read the full lesson →Ethics
Risk & psychologyThe standards governing conduct beyond what is explicitly enforced.
In plain terms
A workable test: if acting on it requires the other side not to know what you know, do not act.
Read the full lesson →Feedback loop
Risk & psychologyThe link between a decision and information about whether it was correct.
In plain terms
Markets give delayed, noisy feedback, which is why experience alone teaches slowly and often wrongly.
Read the full lesson →Framing effect
Risk & psychologyAlso called: Framing, Frame
The change in a decision produced by how the same fact is worded, with no change to the underlying information.
In plain terms
Ninety per cent fat free and contains ten per cent fat are the same packet. It works on people who know it is happening, which is why the defence is a written neutral restatement rather than awareness.
Read the full lesson →Insider trading
Regulation & taxTrading on unpublished price-sensitive information, prohibited under SEBI regulations.
In plain terms
Illegal, prosecuted, and the reason companies impose trading windows on their own staff.
Intrabar path
Technical analysisThe order in which prices were reached inside a bar — information the bar’s four numbers do not carry.
In plain terms
A candle records how far the session reached each way and throws away when. Any rule with a stop and a target depends on the order, and a backtest has to assume one.
Read the full lesson →Limitation period
Regulation & taxThe period within which a claim must be brought — three years for an ordinary money claim, and considerably longer for enforcement against mortgaged property.
In plain terms
It bars the remedy, not the debt: the demand and the credit record both survive it. An acknowledgement in writing, or on the statute's terms a part payment, can start it running again — but only where it is made before the period has already expired.
Read the full lesson →Look-ahead bias
Technical analysisUsing information in a backtest that was not actually available at that point in time.
In plain terms
Trading on a quarterly result weeks before it was filed. Makes any strategy look brilliant.
Read the full lesson →Lookahead bias
Technical analysisUsing information in a backtest that was not available at the time the decision would have been made.
In plain terms
Buying at today’s close because of a signal that only existed once today finished. It roughly doubles backtested returns and is invisible unless you check.
Read the full lesson →Primary research
Fundamental analysisInformation gathered first-hand from customers, dealers, employees and competitors rather than from filings or another analyst's report.
In plain terms
It genuinely leads the reported numbers, and it is a sample you chose yourself. The line it must not cross is unpublished price-sensitive information, which binds the recipient as well as the source.
Read the full lesson →Regrouping
AccountingAlso called: Regrouped and reclassified
Moving prior-year amounts between line items so that they conform to the current year’s presentation, without changing profit after tax.
In plain terms
The one-line note at the foot of the statements that looks like housekeeping. It leaves the bottom line alone and moves any subtotal drawn between the two lines the amount travelled between.
Read the full lesson →SARFAESI Act
Regulation & taxAlso called: SARFAESI
The law allowing banks and notified financial institutions to enforce a security interest — taking possession of and selling a charged asset — without going to court, once the account is non-performing.
In plain terms
No judge, no hearing, and a sequence of notices instead. Each notice is a deadline for the borrower and a requirement on the lender, and a step done badly is the ground on which the whole exercise is set aside.
Read the full lesson →Anchor investor lock-in
Regulation & taxThe lock-in on shares allotted to anchor investors in a public issue, released in two tranches — 50% at 30 days from allotment and the remainder at 90 days.
In plain terms
Split in two deliberately, so the entire anchor book could not become saleable on a single day. Both dates are arithmetic from the allotment date, which makes this the least private information in the market.
Read the full lesson →Auditor resignation
AccountingAn audit firm stepping down mid-term rather than at scheduled rotation.
In plain terms
More informative than anything they might have written. Firms leave when the risk exceeds the fee.
Read the full lesson →Basis
DerivativesThe difference between the futures price and the spot price of the same underlying.
In plain terms
The reason a headline of “GIFT Nifty up 110 points” can describe a flat open. Before treating the gap between two prices as information, check they are the same instrument — the carry alone can be a hundred index points.
Read the full lesson →Bracket order
Trading & ordersAn entry order with a stop-loss and target attached.
In plain terms
Enforces intraday discipline at the cost of flexibility; squared off automatically.
Read the full lesson →Chikou span
Technical analysisAlso called: Lagging span
The Ichimoku lagging line: today’s close plotted twenty-six bars into the past.
In plain terms
Carries no forward information at all. It only tells you whether price is above where it was twenty-six bars ago.
Read the full lesson →Cohort analysis
Fundamental analysisTracking customers grouped by when they were acquired, to see whether each group spends more or less as it ages.
In plain terms
The most informative disclosure a loss-making platform makes. Total user growth can hide complete failure underneath, because fresh acquisition keeps replacing churn.
Read the full lesson →Debenture trustee
Market basicsThe entity appointed to act for the holders of listed debentures, to whom periodic filings on security cover and covenant compliance are made.
In plain terms
Debenture holders never negotiate individually; the trustee holds the security and enforces the terms. Its filings with the exchange say things about a borrower that the annual report does not.
Read the full lesson →Dow Theory
Technical analysisCharles Dow's framework: price discounts everything, prices move in trends, and a trend runs through accumulation, participation and distribution phases.
In plain terms
A century old and still the skeleton under everything in the field, because it describes how information and money propagate through a market — and that has not changed.
Read the full lesson →Earnings drift
Technical analysisThe tendency for prices to continue moving in the direction of an earnings surprise for some time afterwards.
In plain terms
How a stock trades in the session after results is often more informative than the numbers themselves.
Read the full lesson →Fairness opinion
Regulation & taxAn opinion from an independent merchant banker on whether the exchange ratio or the consideration under a scheme is fair to shareholders, required alongside the valuation report where a listed company is involved.
In plain terms
Read it for what it does not cover. It speaks to the ratio, not to whether the transaction is a good idea, and the qualifications in its language usually carry more information than its conclusion.
Read the full lesson →Foreman
Market basicsThe organiser of a chit, who runs the monthly auction, collects instalments, pays out the prize and takes a commission from the discount.
In plain terms
In a registered chit the foreman lodges a security deposit and the commission is capped. In an informal committee the same role carries the same money and none of the safeguards.
Read the full lesson →Groupthink
Risk & psychologyA group converging on a position that no individual member privately holds, because each doubter assumes they are the only one and stays quiet.
In plain terms
It is a failure of information flow, not of intelligence. The tell is not loud agreement — it is that nobody has named a specific way the thing could fail.
Read the full lesson →Indicative NAV
Market basicsAlso called: iNAV
The value of an exchange-traded fund’s underlying basket, computed and disseminated at short intervals during the session, as distinct from the price its units are changing hands at.
In plain terms
An ETF has two prices at once and your chart draws only the traded one. Comparing the two is the fastest way to tell whether a wick was information or a dislocation.
Read the full lesson →Indicator redundancy
Technical analysisThe condition in which several indicators appear to confirm one another while being different arrangements of the same underlying price data.
In plain terms
RSI, Stochastic, Williams %R, CCI and the MACD histogram all agreeing is one opinion reported five times. New information has to come from a different input — volume, breadth, relative strength.
Read the full lesson →Market depth
Trading & ordersAlso called: Order book depth
The list of pending buy and sell orders at each price level, usually shown five deep.
In plain terms
The most informative panel on your broking screen and the one nobody looks at.
Read the full lesson →MD&A
Fundamental analysisAlso called: Management Discussion and Analysis
Management Discussion and Analysis — the statutory narrative section of an annual report in which management explains the year's performance.
In plain terms
Read it for what it avoids. If margins fell and the section discusses industry tailwinds without ever naming margins, the omission is the information.
Read the full lesson →Mean reversion
Technical analysisA strategy that buys weakness and sells strength, expecting price to return towards an average.
In plain terms
The rubber band. Wins often, loses large, and works only where the fall was movement rather than information.
Read the full lesson →NCD
Market basicsNon-Convertible Debenture — a tradeable corporate bond sold to the public.
In plain terms
Best case a few percent extra; worst case the principal. The rating is the most informative line.
Read the full lesson →Non-performing asset
Regulation & taxAlso called: NPA
A loan account on which an amount has remained overdue beyond the prescribed period — ninety days for most loans — requiring the lender to make a provision against it out of its own profits.
In plain terms
The line past which a lender's posture changes from collection to enforcement. It is also the gate to the statutory power to sell a mortgaged asset.
Read the full lesson →Overreaction
Technical analysisAn initial price move larger than the news itself justifies.
In plain terms
Stop cascades add selling unrelated to the news, which is why the first print is not information.
Read the full lesson →Oversubscription
Market basicsAn IPO receiving applications for more shares than are on offer, reported as a multiple of the issue size.
In plain terms
Read it by category, never by the headline. QIB demand is the informative number, and a large multiple on a small issue is easy to generate while saying almost nothing about the business.
Read the full lesson →Price-time priority
Trading & ordersThe exchange matching rule: the better price executes first, and among equal prices the order that queued earliest executes first.
In plain terms
It disposes of the belief that the exchange favours large players — the matching engine cannot see who you are. What size actually buys is speed and information, within the same rules.
Read the full lesson →Rating outlook
Fundamental analysisAn agency’s view on the likely direction of a rating over the medium term.
In plain terms
Often more informative than the letters. A negative outlook typically precedes a downgrade by months.
Read the full lesson →Resulting
Risk & psychologyJudging the quality of a decision by how it turned out rather than by the reasoning available when it was made.
In plain terms
The dangerous box is not the sound decision that lost — it is the rule violation that paid, because indiscipline has just been reinforced with money.
Read the full lesson →Retail investor
Market basicsAn individual investing their own money, as distinct from institutional, proprietary and promoter participants.
In plain terms
Small individually and very large collectively. The genuine edge is a long horizon, no redemption pressure and the freedom to hold cash — never speed or information.
Read the full lesson →Retail shareholder count
Fundamental analysisThe number of individual small shareholders on a company's register, disclosed each quarter in the shareholding pattern.
In plain terms
Rising sharply while institutions reduce is the shape of informed money selling to newcomers.
Read the full lesson →ROA
Fundamental analysisAlso called: Return on assets
Return on assets — net profit as a percentage of total assets.
In plain terms
Unlike ROE it cannot be lifted by swapping equity for debt, because the borrowed money still sits in the asset base. Most informative for banks and lenders, where the assets are the business.
Read the full lesson →Sample variance
Risk & psychologyThe spread of outcomes you would see from repeated draws of the same underlying process.
In plain terms
Thirty trades is thirty trades of information, however many times you reshuffle them. A small sample presented a thousand ways is still a small sample.
Read the full lesson →Screen time
Risk & psychologyHours spent watching live prices and market media.
In plain terms
It provides no information a weekly review misses and manufactures the urge to act.
Read the full lesson →Section 269SS
Regulation & taxAn income-tax provision requiring loans, deposits and advances above a prescribed amount to be taken otherwise than in cash; Section 269T applies the same restriction to repayment.
In plain terms
It catches ordinary family arrangements. An informal loan settled in cash exposes both sides to a penalty equal to the amount, which is an expensive way to do somebody a favour.
Read the full lesson →Secured creditor
Regulation & taxA lender holding a charge over an identified asset, with a claim on that asset ahead of unsecured creditors.
In plain terms
Whether your lender is one decides how a default unfolds. A home loan lender has a statutory route to the flat; an app that lent you ₹40,000 has a slow civil one to nothing in particular.
Read the full lesson →Smoothing
Technical analysisAveraging price data to suppress short-term noise, as Heikin-Ashi does by blending each bar with the one before it.
In plain terms
It buys clarity by discarding information, and it flatters backtests badly — because the whipsaws it removed are exactly the ones that would have stopped you out live.
Read the full lesson →Third-party liability
Market basicsMotor cover for death, injury or property damage caused to somebody else — compulsory by statute for every vehicle on a public road.
In plain terms
For death and injury there is no ceiling: the award is computed from the deceased’s earnings, prospects, dependants and age, and has nothing to do with the value of your car. Lapse it and that award is enforced against you.
Read the full lesson →Trading window
Regulation & taxThe period in which designated persons of a listed company may transact in its securities; it is closed from the end of each quarter until 48 hours after the results for that quarter are declared.
In plain terms
Four blocked stretches a year, roughly a third of it, before any unscheduled closure. It shuts on you regardless of what you actually know, because a rule that turned on individual knowledge could never be enforced.
Read the full lesson →Variance ratio
Technical analysisThe measured variance of an n-period move divided by n times the variance of a one-period move.
In plain terms
A direct test of the square-root-of-time assumption. Above one and moves have been reinforcing each other; below one and they have been cancelling out; at one the series behaves like a random walk over that horizon.
Read the full lesson →Volume smile
Trading & ordersThe shape traded volume makes across a session — heavy at the open, thin through the middle of the day, heavy again into the close.
In plain terms
Both ends hold most of the day's information and most of its danger. The first fifteen minutes are the most expensive; the close has the deepest liquidity.
