Put
DerivativesAlso called: Put option
An option giving its buyer the right, but not the obligation, to sell the underlying at a set price up to expiry.
In plain terms
Bought either to profit from a fall or to insure a holding against one. The gain is large but capped, because a price cannot go below zero.
Read the full lesson →Put-call ratio
DerivativesAlso called: PCR
Open interest in puts divided by open interest in calls, read contrarily as a gauge of crowd positioning.
In plain terms
Open interest does not record intent. Heavy put positioning is often institutions selling puts at a strike they are happy to buy at — bullish positioning that a naive reading reports as fear.
Read the full lesson →ODR
Regulation & taxAlso called: Online Dispute Resolution
Online Dispute Resolution — the online route for conciliation and then arbitration of an investor's dispute with a market intermediary.
In plain terms
The stage after SCORES and before the courts. Binding, far cheaper than litigation, and it exists precisely because a civil suit is not a realistic remedy for a ₹40,000 dispute.
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 →Imputed rent
Market basicsThe rent an owner-occupier implicitly pays themselves by living in a property they own.
In plain terms
The money you are not paying a landlord. It is a real benefit of owning and it never shows up in a bank statement.
Read the full lesson →Analyst question
Fundamental analysisAn unscripted question put to management during an earnings call.
In plain terms
When three analysts ask the same thing, either it matters or the first two answers were poor.
Read the full lesson →Anchored VWAP
Technical analysisVWAP computed from a chosen starting bar rather than from the session open.
In plain terms
The average price everyone has paid since an event. Above it, they are in profit; below it, they are not.
Read the full lesson →Arbitration
Regulation & taxA binding dispute-resolution stage reached through the online dispute resolution mechanism once conciliation has failed.
In plain terms
Binding, far cheaper than court, and measured in months where a civil suit is measured in years. What it runs on is the paper trail you kept.
Read the full lesson →Capital gains statement
Regulation & taxThe financial-year statement a broker produces listing every sale, split into short-term and long-term with the cost basis already computed.
In plain terms
Your primary source at filing time and usually a two-click download. Reconcile it against the AIS before you submit anything.
Read the full lesson →Ceiling price
Regulation & taxThe maximum price at which a scheduled formulation may be sold, computed by the National Pharmaceutical Pricing Authority as the simple average of the prices to retailer of brands above a 1% share of that formulation, plus a notified 16% retailer margin.
In plain terms
It is revised annually against the wholesale price index — an index with no connection to what the company paid for its active ingredient. That asymmetry is the whole structural feature of price control.
Read the full lesson →Contingent liability
AccountingAlso called: Contingent liabilities
An obligation that may arise depending on a future event — tax disputes, guarantees, litigation.
In plain terms
Not on the balance sheet. If the total exceeds net worth, a material risk is hiding in a footnote.
Read the full lesson →Cost of acquisition
Regulation & taxWhat you actually paid for an asset, used with the date of acquisition to compute the gain when it is sold.
In plain terms
Not held by the depository and invisible to a new broker. Moving accounts changes nothing about it and everything about who can prove it — which is why the old statements are what you take with you.
Read the full lesson →Crude oil
Market basicsThe commodity India imports the large majority of and pays for in dollars, making its price an input into inflation, the trade deficit and the rupee at once.
In plain terms
The loop is the point: a spike widens the deficit, which weakens the rupee, which makes the same oil dearer in rupee terms. It hurts paints, tyres, airlines and logistics, and helps upstream producers.
Read the full lesson →Drawing power
Fundamental analysisThe amount actually available under a working capital limit at a point in time, recomputed against stock and receivables after prescribed margins.
In plain terms
It is why a sanctioned limit contracts exactly when the business contracts. The ceiling stays where it was and the money that can be drawn against it falls with the inventory and the debtors.
Read the full lesson →Expected credit loss
AccountingAlso called: ECL
The allowance a lender carries against a loan from the day it is written, computed as the probability of default multiplied by the loss if default happens, applied to the exposure at that point.
In plain terms
A model output, not a measurement. Two lenders with the same borrowers can carry materially different numbers and both be perfectly compliant, which is why the notes also compare it with the regulator’s formula.
Read the full lesson →Flat rate interest
Market basicsAlso called: Flat rate
Interest computed on the original amount borrowed for the whole tenure, regardless of how much principal has already been repaid.
In plain terms
Rent on rooms you have already handed back. For a fully repaid term loan a flat rate is close to double itself once converted to a reducing basis — before fees.
Read the full lesson →Haircut
Market basicsThe percentage deducted from the value of pledged collateral when computing available margin.
In plain terms
Pledge ₹1,00,000 with a 20% haircut and you get ₹80,000 of margin. Haircuts widen exactly when markets get volatile.
Read the full lesson →Incentive
Risk & psychologyThe financial or reputational reward shaping what a source produces and emphasises.
In plain terms
Free content is paid for by someone. Working out who, and for what, explains most of what you are shown.
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 →Inflation pass-through
Fundamental analysisThe extent to which a company can pass rising input costs on to customers.
In plain terms
A cost spike is a free experiment. Margins hold if there is pricing power, compress if there is not.
Read the full lesson →Installed capacity
Fundamental analysisAlso called: Rated capacity, Nameplate capacity
The maximum output a company’s plants are rated to produce over a period, disclosed in units rather than rupees.
In plain terms
The ceiling on volume growth without fresh capital expenditure. Set beside actual production it gives capacity utilisation, and beside industry-wide additions it tells you what supply is coming.
Read the full lesson →Open offer
Regulation & taxThe offer an acquirer must make to public shareholders on crossing the shareholding thresholds prescribed in the takeover regulations, or on acquiring control, at a price computed under those regulations, unless an exemption applies.
In plain terms
It is for a stated proportion of the shares rather than all of them, so it is not a floor under your whole holding. Where the computed price lands above the market the price tends to sit just under it and the daily range flattens; where it lands below, almost nobody tenders and the chart is unaffected.
Read the full lesson →Options
DerivativesA contract giving the right, but not the obligation, to buy (call) or sell (put) at a set price.
In plain terms
Buyers risk only the premium. Sellers take limited gain for potentially very large loss.
Polled spot price
DerivativesAlso called: Spot polling
A spot price computed by surveying physical market participants at a designated delivery centre under a published methodology, rather than from an order book.
In plain terms
It is a survey taken once or twice a day, not a continuously traded series. Reading a divergence between it and the futures as though both were live prices misreads what one of the two numbers is.
Read the full lesson →Portfolio liquidation time
Market basicsThe headline figure of the fund liquidity stress test — the days needed to sell 25% and then 50% of the portfolio, computed pro-rata against trailing traded volumes.
In plain terms
Driven mostly by fund size measured against the volumes of what it owns, so the numbers cluster by size rather than by skill. The least liquid fifth of the portfolio is excluded before the figure is calculated, which is the single most important thing to know about it.
Read the full lesson →Pre-open session
Trading & ordersAlso called: Opening auction, Pre-open auction
The 9:00–9:15 window in which the NSE collects orders and computes a single opening price.
In plain terms
Orders collect until 9:08, match until 9:12, and everyone who trades gets the same equilibrium price.
Read the full lesson →Reducing balance
Market basicsAlso called: Reducing balance interest
Interest computed each period on the principal still outstanding, so the interest component falls as the loan is repaid.
In plain terms
The only basis on which two loan quotes can be compared. A quote that does not say which basis it uses is not yet a quote.
Read the full lesson →Reinvestment rate
Fundamental analysisAlso called: Reinvestment
The share of profits a company puts back into the business rather than distributing.
In plain terms
Sustainable growth is roughly incremental return multiplied by this. A high return with nowhere to deploy it is worth little.
Read the full lesson →Robustness
Technical analysisHow well a strategy holds up when its inputs, period or ordering are changed.
In plain terms
A rule that only works on the stock and window you found it on is not robust — it is a coincidence with a story attached.
Read the full lesson →Rolling returns
Market basicsReturns computed from every possible start date rather than one fixed window.
In plain terms
Far more honest than a since-inception figure, which usually includes a first year nobody can access now.
Read the full lesson →Rupee
Market basicsIndia's currency, whose exchange rate against the dollar is itself an input into what listed companies earn.
In plain terms
A weaker rupee helps IT and pharma exporters and hurts importers, airlines and anyone paying for crude in dollars.
Read the full lesson →SPAN margin
DerivativesThe core initial margin on a derivatives position, computed as the worst single-day loss across a grid of simulated price and volatility scenarios.
In plain terms
It rises when volatility rises, which is precisely the day the position is losing money. The margin call and the loss are correlated by design, and that correlation is what turns a bad session into a forced exit.
Read the full lesson →Supplier concentration
Fundamental analysisDependence on one vendor or input with no ready substitute.
In plain terms
The mirror image of customer concentration, and disclosed far less clearly.
Read the full lesson →Total return index
Market basicsAlso called: Price index, Price return index
The same index basket computed with dividends reinvested, as against the price index, which excludes them.
In plain terms
Over weeks the difference is invisible; over a decade it is two different-looking charts. Any statement that “the index went nowhere” is being made on the series that throws the dividends away.
Read the full lesson →Trade payables ageing schedule
AccountingThe Schedule III note splitting trade payables by period outstanding from the due date, and separately between micro and small enterprise creditors and others, with disputed dues shown apart.
In plain terms
The disclosure that turns one balance into a story. Bargaining power keeps almost everything inside a year; a filling one-to-two-year bucket suggests the terms were taken rather than agreed.
Read the full lesson →Variable cost
AccountingA cost that rises and falls broadly in proportion to output or sales.
In plain terms
Raw materials and freight. Double the sales, double the spend, and the margin barely moves.
Read the full lesson →Adjusted price
Technical analysisA price series restated for splits, bonuses and other corporate actions.
In plain terms
Without it, a bonus looks like a 50% crash and every indicator computed across it is nonsense.
Read the full lesson →Amortisation schedule
Market basicsThe instalment-by-instalment split of a loan repayment between interest and principal across its full tenure.
In plain terms
Early instalments are almost all interest because interest is charged on the outstanding balance. Restarting the tenure puts you back at the interest-heavy end.
Read the full lesson →Anchor investor
Market basicsAn institution allotted shares in a public issue a day before it opens to everyone else, at a price fixed in advance.
In plain terms
Read the names, not the amount. Reputable long-only funds anchoring a book is meaningful; a book made up of unfamiliar entities is not.
Read the full lesson →Circle rate
Regulation & taxAlso called: Ready reckoner rate, Guidance value, Guideline value
The minimum value per unit area notified by a state government for property transactions in a locality.
In plain terms
Stamp duty is charged on the higher of the documented price and this notified value, and the income tax provisions for immovable property key off the same figure — so in a weak local market duty and tax can be computed on a price nobody is actually paying.
Read the full lesson →COGS
AccountingAlso called: Cost of goods sold
Cost of goods sold — the direct cost of producing what was actually sold in the period.
In plain terms
Revenue minus this is gross profit, the purest read on pricing power. Rising faster than revenue means input costs are not being passed on.
Read the full lesson →Corporate action adjustment
Fundamental analysisAlso called: Adjusted per-share series
Restating historical per-share figures for bonus issues, splits, rights issues and similar events so that a per-share series remains continuous.
In plain terms
Bonuses and splits divide by a simple factor. A rights issue priced below the market contains an element of bonus, so it needs a computed factor rather than a divisor.
Read the full lesson →CPI inflation
Market basicsConsumer price inflation, published monthly; the RBI targets 4% with a 2–6% band.
In plain terms
Above the band the RBI raises rates, and that is the channel that reaches your portfolio. Consumer companies take a second hit through input costs they cannot always pass on.
Read the full lesson →DCF
Fundamental analysisDiscounted Cash Flow — valuing a business as the present value of its projected future cash flows.
In plain terms
Its real output is a range and a set of stated assumptions, never a target price.
Read the full lesson →Family agreement
Risk & psychologyA shared understanding among relatives about an indivisible asset.
In plain terms
Have the conversation before acting. Silent assumptions turn a shared inheritance into a decade-long dispute.
Read the full lesson →Going concern
AccountingThe assumption that a company will continue operating for the foreseeable future, on which the accounts are prepared; where material doubt exists, the auditor reports it.
In plain terms
A paragraph on material uncertainty relating to going concern is an auditor putting the fragility in writing, in a signed document. It is not a prediction of failure, and it is not an item to skim past either.
Read the full lesson →GST registration
Regulation & taxCompulsory registration under the Goods and Services Tax above a turnover threshold, or immediately in certain interstate cases.
In plain terms
Registering voluntarily lets you claim input credit and commits you to periodic returns permanently.
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 →KYC Registration Agency
Regulation & taxAlso called: KRA
A SEBI-registered agency that holds an investor’s KYC record centrally, keyed on the PAN, and shares it with other intermediaries.
In plain terms
Five of them share records between themselves, which is why a second broker did not put you through the whole process again — and why one deficient record can block a fresh purchase everywhere at once. The status is free to check with nothing but a PAN.
Read the full lesson →Litigation risk
Fundamental analysisPotential loss from legal claims against a company.
In plain terms
Read what the cases are about. A product liability claim implies something structural; a commercial dispute usually does not.
Read the full lesson →Market wide position limit
DerivativesAlso called: MWPL
A cap set by the exchange on the aggregate derivatives open interest permitted in a single stock, expressed as a number of shares.
In plain terms
It stops the derivatives tail growing large enough to wag the cash market. The basis on which it is computed has been revised, so read the current circular for the formula — what has not changed is that the names reaching the ceiling are overwhelmingly midcaps with concentrated promoter holdings and thin deliverable float.
Read the full lesson →Minority interest
AccountingThe share of a subsidiary’s profit belonging to other shareholders.
In plain terms
Compute per-share figures after deducting it, or you overstate earnings.
Read the full lesson →Multi-year tariff
Regulation & taxAlso called: MYT
A tariff determined by an electricity regulatory commission for a control period spanning several years rather than annually.
In plain terms
It puts the next revision on a published calendar, with draft regulations and objections available months before the order. Between control periods the risk is not demand — it is that a cost is disallowed or the permitted return is trimmed.
Read the full lesson →Natural hedge
Fundamental analysisForeign currency revenue and costs that offset each other.
In plain terms
An exporter who also imports most inputs has far less net exposure than its revenue suggests.
Read the full lesson →Normalisation
AccountingAdjusting reported figures so two companies can be compared fairly.
In plain terms
Recompute both at the statutory tax rate, strip one-offs, and add guarantees to debt.
Read the full lesson →Option chain
DerivativesThe strike-by-strike table of open interest, change in open interest, volume and implied volatility for an underlying's options, published live and free by the NSE.
In plain terms
The strike with the largest call open interest often acts as resistance and the largest put strike as support, because writers hedging those positions generate real buying and selling. One source of confluence, not a forecast.
Read the full lesson →Periodic call auction
Trading & ordersA trading mode in which orders collect through a window and match at a single price at the end of it, instead of matching continuously.
In plain terms
There is no live bid-ask to work against — you place an order and learn afterwards what it did. That is precisely why illiquid and surveillance-bound securities are the ones put into it.
Read the full lesson →Price target
Technical analysisA pre-defined level at which a position will be closed for profit.
In plain terms
Compute it before entering. Its job is deciding whether to take the trade at all.
Read the full lesson →Regulated return on equity
Fundamental analysisThe return on equity a regulator permits an asset to earn, built into the allowed revenue alongside approved capital cost, depreciation, operations and maintenance and interest.
In plain terms
The commission sets a return rather than a price, so the analysis moves to the allowance and the disallowances. Regulatory lag is where the margin actually goes: between an input cost rising and a tariff order recognising it, the company funds the gap itself.
Read the full lesson →Risk-adjusted comparison
Risk & psychologyComparing two returns only after accounting for the certainty, the tax treatment and the horizon attached to each.
In plain terms
Put both after tax and the gap is usually far narrower than the headline version suggests. Which tax regime you are on moves the hurdle by points, not decimals.
Read the full lesson →Sandwich generation
Risk & psychologyEarners supporting both parents and children at the same time.
In plain terms
One candle, two rooms. Put the support in the plan as a line item rather than hoping it fits.
Read the full lesson →Scaling in
Technical analysisBuilding a position in several tranches rather than in one order.
In plain terms
Each tranche is its own sizing problem, computed from the current stop rather than the original one.
Read the full lesson →Sensitivity analysis
Fundamental analysisRe-running a valuation across a range of growth and discount-rate assumptions to see how far the answer moves.
In plain terms
The output is a spread rather than a figure, and the spread is the honest answer. A DCF quoted to the rupee is a claim the model cannot support.
Read the full lesson →Stale price
Technical analysisAlso called: Stale quote
A quoted price carried forward from an earlier trade because the security has not traded since, so the figure describes a moment that may be hours or days old.
In plain terms
The last traded price is exactly that and nothing more. On a thin name the number on your screen on Friday can be Tuesday’s, and every percentage you compute against it inherits the age.
Read the full lesson →Standard deviation
Technical analysisA statistical measure of how widely a series is dispersed around its own average; Bollinger Bands sit two of them either side of a 20-day mean.
In plain terms
It is recomputed every session, which is why the bands widen when a stock turns volatile and contract when it goes quiet. Touching a band means statistically unusual, never expensive.
Read the full lesson →STP
Market basicsSystematic Transfer Plan — moving a fixed amount from one fund to another at intervals.
In plain terms
The sensible way to deploy a lumpsum into equity instead of putting it all in on one day.
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 →Volatility crush
DerivativesAlso called: IV crush
The collapse in an option’s premium after a scheduled event, as the expected volatility the price was carrying resolves into a known outcome.
In plain terms
It is why you can be right about the direction of the underlying and still lose on the option. The input that moved is not visible anywhere on the premium chart.
Read the full lesson →Volume
Technical analysisThe number of shares traded in a given period.
In plain terms
The only widely used input that is not derived from price, which makes it worth more than the four oscillators sitting under your chart. A breakout without a volume surge is a suspect breakout.
