Risk Management 101

Risk is the chance of a bad outcome: losing money, or not being able to get it back when you need it. Risk management names those outcomes and sets limits before you act. It makes some losses smaller. It does not remove uncertainty.

ITC's past year shows several kinds of risk in one chart. The price peaked at ₹426.40 on 31 October 2025. On 1 and 2 January 2026 it fell from ₹403.00 to a low of ₹345.25, a 14.33% drop in two sessions (derived), after the government announced a new excise duty on cigarettes late on 31 December 2025. It reached ₹253.15 on 8 October 2026 and closed at ₹260.80 on 19 October 2026.

Market risk is a broad fall in prices. Business risk comes from the company itself, or from a rule that hits its business, like that excise duty. Liquidity risk means you cannot sell the quantity you need at a fair price. Credit risk means a borrower, or the other side of an agreement (a counterparty), fails to pay.

Concentration means too much money in one company, sector or shared cause. Leverage means borrowing or using contracts to hold more than your own money covers. Operational risk covers wrong orders, rejected orders, outages and fraud. Inflation can shrink what money buys even when the rupee amount stays the same.

In this lesson Mr. Chartist keeps three numbers apart: the money committed, the loss he plans for, and the loss in a worse case. ITC is the course's running example. Prices are real NSE prices; quantities and capital are labelled teaching assumptions. The ideas work in any market, though local order rules differ.

Financial capacity is your ability to take a loss without missing rent, a loan payment or family costs. Risk tolerance is how comfortable you feel with ups and downs. Feeling comfortable does not create the money for rent.

Take an illustrative household with ₹5,00,000. Of that, ₹1,50,000 is needed for bills due soon and ₹50,000 is an emergency reserve. That leaves ₹3,00,000 for further planning (derived). The amounts only show how to separate purposes. They are not advice on reserve sizes, and the remainder is not automatically money to trade.

A time horizon is how long until you need the money. If a payment is due soon, a temporary fall can force you to sell at a loss. A longer horizon gives more time, but it cannot save every company or promise a recovery.

When you size a trade, say clearly what "capital" means: for example, the money set aside for trading today. Not total family wealth, and not a credit limit. Keep taxes, charges and money already promised visible. Cash available and account value are different numbers.

Choosing not to trade is a valid result of this check. A small planned loss does not make money meant for essentials suitable for speculation.

Exposure is the amount of money that moves when a price moves. A position is one holding. A portfolio is all your holdings together. A position's weight is its value divided by the portfolio's value.

Picture an illustrative ₹5,00,000 portfolio that held 234 ITC shares at the 31 October 2025 high of ₹426.40. That holding was worth ₹99,777.60, about 20% of the portfolio. At the 8 October 2026 low of ₹253.15, the same 234 shares were worth ₹59,237.10. The holding lost ₹40,540.50, or 40.6% (derived).

If every other holding stayed flat, the whole portfolio fell by about 8.1% (derived). The 20% weight is what turned a 40.6% fall in one share into an 8.1% fall in the account. The share count is an illustration; the prices are NSE's. The figures are price only and leave out the ₹14.50 of dividends ITC paid for 2025-26.

Fully paid means you bought with your own money, not a loan. Long means you own the shares. A short sale starts by selling shares you do not own, with a duty to deliver or return them, and its losses work differently.

A fully paid long holding can, in the worst case, lose all of its purchase value. Borrowed or short positions can lose more than that. A long-term investor manages risk through how much to hold, company quality and spreading money out. A short-term trader may also set a price-based exit. Neither makes the purchase price irrelevant.

Volatility is how much a price swings. A permanent loss can follow a business problem, paying too much, or being forced to sell. The asset-allocation lesson takes this beyond a single share.

Drawdown is the fall from an earlier peak. Measure it on the same basis each time, and keep deposits and withdrawals separate from investment results. A loss you have not sold is still a loss in today's value.

ITC's price fell from ₹426.40 to ₹253.15: a drawdown of 40.63% (derived). To get back to ₹426.40 from ₹253.15, the price must rise ₹173.25 on a base of ₹253.15. That is a gain of 68.44% (derived). The fall and the recovery use different starting points, so the percentages differ.

The same arithmetic works for any amount. A 20% fall needs a 25% gain to recover. A 50% fall needs 100%. A 90% fall needs 900%. For a loss fraction d below 1, the gain needed is d ÷ (1 − d). Multiply by 100 for a percentage. All of these are derived arithmetic.

At a 100% loss there is nothing left to grow, so no gain can recover it. Adding new money restores the balance but is not a recovery. The formula also says nothing about how long a recovery takes, or whether it happens at all.

Write down both the drawdown and its cause. Small planned losses, several positions falling together and costs can add up. A limit on one position is not a limit on the whole account.

Each loss shrinks the money left for the next decision. A stress test asks what a chosen run of losses would do. It does not say how likely that run is.

As a teaching assumption, start with ₹1,00,000 and take ten losses in a row, each exactly 1% of what is left. You end with ₹1,00,000 × 0.99¹⁰ ≈ ₹90,438. At 2% a loss you end with about ₹81,707. At 10% a loss you end with about ₹34,868 (all derived).

To get back to ₹1,00,000 from there needs gains of about 10.57%, 22.39% and 186.80% (derived). The model assumes each loss is exactly the planned size, with no costs, no wins and no deposits or withdrawals. Gaps can make real losses bigger.

Risk of ruin is the chance of falling below a level where you can no longer continue, or can no longer meet a payment. Estimating it needs the size and frequency of losses, whether losses come together, costs and that failure level. A table of losing streaks does not supply those.

A losing run can come from chance, changed conditions, poor execution or a flawed method. Following written rules does not prove the rules work. Review the method; do not raise size to win it back.

A loss budget is the amount you allow one trade to lose at its planned exit, decided before you buy. The well-known "1% rule" is a habit some traders use, not a law and not a promise that the loss will stop there. The right figure depends on your situation and the product.

As a teaching assumption, Mr. Chartist sets aside ₹5,00,000 as trading capital and chooses 1%. His loss budget is ₹5,000. That is how much he plans to lose if the trade fails. It is not the amount he invests, and it is not a percentage every reader should use.

Keep three amounts apart: what you pay, what you plan to lose at your exit, and what you could lose in a worse case. In the next chapter a ₹1,69,259.20 ITC position has a planned loss of only ₹4,997.30 (derived). The whole ₹1,69,259.20 is still exposed if things go badly.

Costs, an opening gap and a lack of buyers can all push a loss past the plan. An opening gap is when the next trade happens at a price beyond your exit level. The budget needs room for costs and a worse fill, not just a percentage in a notebook.

Recalculate from today's capital each time. Using an old, larger balance after losses quietly raises the percentage at risk. Check the new trade and everything already open before deciding it fits.

Position sizing turns a budget, an entry price and a planned exit into a share count. For a long cash-share trade, the loss per share is entry minus exit. Divide the budget by that loss per share, then round down to a whole share.

Mr. Chartist uses real ITC levels. Entry is ₹260.80, the 19 October 2026 close. His exit is ₹253.10, one tick (₹0.05) below the past-year low of ₹253.15 from 8 October 2026. The loss per share is ₹7.70, or 2.95% of the entry (derived).

₹5,000 ÷ ₹7.70 = 649.35, so he can buy 649 whole shares (derived). The purchase costs ₹1,69,259.20, about 33.9% of his ₹5,00,000. The planned loss at ₹253.10 is ₹4,997.30, before costs (derived).

Now he keeps ₹500 aside for charges and slippage (a teaching allowance, not a broker's tariff). Slippage is the gap between the price you expect and the price you get. Price-loss room becomes ₹4,500, and ₹4,500 ÷ ₹7.70 rounds down to 584 shares. Planned price loss is ₹4,496.80, or ₹4,996.80 with the allowance. The purchase costs ₹1,52,307.20 (all derived). A gap or other cost can still exceed the allowance.

Check that the exit is below the entry and the distance is more than zero. A wider distance means fewer shares on the same budget. Short sales and derivatives need their own calculation. Lesson 12 has a sizing calculator you can try with your own numbers.

Cash is a second limit on quantity. The purchase, the charges and any margin (money or collateral held against a position) must fit the funds you have. A share count from the risk sum is only a candidate, never a reason to borrow.

Suppose Mr. Chartist puts his exit at the 19 October 2026 low of ₹259.95 instead. The loss per share is just ₹0.85. ₹5,000 ÷ ₹0.85 gives 5,882 shares. Those would cost ₹15,34,025.60, about 3.07 times his ₹5,00,000 (all derived).

His cash allows at most 1,917 shares, because 1,917 × ₹260.80 = ₹4,99,953.60, leaving ₹46.40 before charges. At that size the planned loss to ₹259.95 is ₹1,629.45 (derived). Charges would cut the quantity further.

Use the smallest quantity that passes every check: funds, loss budget, costs and product rules. A market lot is the fixed number of units in one tradable lot. Cash shares on NSE trade in single shares; futures and options trade in lots, and one ITC futures lot in October 2026 was 1,725 shares.

A very tight exit gives a huge share count and almost no room for the price's normal wiggle: ITC moved ₹3.95 between its high and low on 19 October 2026 alone. Check concentration and the quantity buyers actually offer too. Borrowing changes the risk; it does not solve the cash limit.

An exit plan says what would prove the reason for a trade wrong, and how you would get out. A chart support level (a price where buying stopped a fall before), a percentage limit or news about the business can each set it. No method is always right, and a chart level is only a guess.

A stop order waits until its trigger price is reached. On NSE, a sell stop triggers when the last traded price reaches or falls below the trigger, and then joins the normal order book. It does not wait for the day's close. Check what your product and broker support.

A market order takes whatever prices are available. A stop that releases a market order can fill worse than the trigger. A stop-limit sets the worst price you accept, but may not fill at all if buyers will not pay it. A DAY order on NSE is cancelled at the end of the day if it has not filled, so check how your broker handles orders meant to last longer.

ITC shows a real gap. On 1 January 2026 its lowest trade was ₹362.70 and it closed at ₹363.85. On 2 January 2026 the first trade was at ₹360.00, which was also the day's high, and the low was ₹345.25. Every trade that day was below the previous day's low. A sell stop with a trigger at, say, ₹362.00 left overnight could not fill at ₹362.00.

Worked example (illustration): 100 shares bought at the 31 December 2025 close of ₹403.00, with a sell stop at ₹362.00. The planned price loss is ₹4,100. If the stop filled at the ₹360.00 opening price, the loss would be ₹4,300, or ₹200 more than planned (derived). Real fills are not published, and some could have been lower. The day's low was ₹345.25.

Not every drop is a loss. On 27 May 2026, its ex-dividend day for the ₹8 final dividend, ITC opened at ₹295.65 against a ₹301.65 close the day before: ₹6.00 lower (derived). Shareholders on record received that dividend. A stop placed just under the old price could trigger on a drop that was mostly the dividend leaving the price.

Planning to sell after a candle (one period's price summary) closes is a rule you must act on yourself. A mental stop needs you to act at the hard moment. Neither a mental rule nor a submitted order guarantees an exit; check its status.

Liquidity is how easily you can buy or sell the quantity you need without moving the price much. The spread is the gap between the best price buyers bid and the best price sellers ask. Depth is how many shares wait at each price.

Past order books are not published, so here is an illustrative book on real ITC price levels near the ₹260.80 close. Buyers wait for 400 shares at ₹260.75, 600 at ₹260.70, 500 at ₹260.65, 900 at ₹260.60 and 1,200 at ₹260.55; sellers ask from ₹260.80 upward. The quantities are an illustration.

Selling 300 shares fills fully at ₹260.75, for ₹78,225 (derived). Selling 1,917 shares uses the top four buy levels: 400 at ₹260.75, 600 at ₹260.70, 500 at ₹260.65 and the last 417 at ₹260.60. Proceeds are ₹4,99,715.20, an average of about ₹260.68 (derived).

Multiplying all 1,917 shares by the top bid of ₹260.75 would give ₹4,99,857.75, overstating the result by ₹142.55 (derived). Costs are left out, and a real book can change before your order arrives.

ITC is a busy stock: 1,15,28,925 shares traded on NSE on 19 October 2026. Even so, a large order can fill across several prices. A market order can eat through levels. A limit order controls the price but may fill only partly. Liquidity matters most when many people want to sell at once, and halts or price limits can block a sale. The first-order and stock-quote lessons cover order types and depth.

Leverage means holding more market exposure than your own money covers. Borrowing and some derivatives (contracts linked to an underlying asset) create it in different ways. Margin is the money or collateral (assets pledged as security) a position requires. It is not a promise that losses stop at that amount.

Take the same ₹7.70 fall per share, from ₹260.80 to ₹253.10. Mr. Chartist's 649 cash shares lose ₹4,997.30. One ITC futures lot in October 2026 was 1,725 shares, and the October future closed at ₹261.80 on 19 October 2026, so one lot carried about ₹4,51,605 of exposure (derived). The same ₹7.70 move on one lot is ₹13,282.50, about 2.66 times the cash loss (derived). The margin a broker blocks is far smaller than the exposure.

A plain borrowing example shows the same effect (teaching assumption). ₹1,00,000 of your own money buys ₹1,00,000 of shares: a 10% fall costs ₹10,000. If the same ₹1,00,000 supports ₹5,00,000 of shares with ₹4,00,000 borrowed, a 10% fall costs ₹50,000. The debt stays at ₹4,00,000, so half your own money is gone before interest (derived).

SEBI's August 2026 study of individual traders in equity futures and options found that 87.7% had net losses in 2025-26, down from 90.9% in 2024-25. Together they lost ₹91,685 crore in 2025-26, an average of about ₹1.17 lakh per trader. Traders with equity portfolios below ₹1 lakh were 78% of traders and carried 70% of the losses.

Lenders and brokers can ask for more money or close positions under their terms. A bad move plus financing costs can create losses larger than the money you put up. Leverage does not improve the reason for a trade. Read the margin, leverage and pledging lesson before using any provider's facility.

Risk-to-reward compares a planned loss with a planned gain. Traders call the planned loss per share 1R. R is not a guaranteed limit; real losses can be bigger.

On the ITC plan, entry is ₹260.80 and the exit is ₹253.10, so 1R is ₹7.70. A target of 2R would sit at ₹276.20, and 1R above entry at ₹268.50 (derived). The target is an illustration of the arithmetic, not a forecast that ITC will get there. Costs are left out.

A target is a hoped-for exit, not evidence that the price will reach it. A stop distance shows the plan's bad case, not every possible loss. A bigger target can be harder to reach, and a higher ratio does not make a trade better.

In a model where every win is exactly 2R and every loss exactly 1R, before costs, you break even if one trade in three wins: 1 ÷ (1 + 2) = 33.33% (derived). This is a model condition, not a success rate anyone has achieved.

When results vary, use the average wins and losses you actually got, not the target you hoped for. Partial exits, gaps, costs and missed fills all change those averages.

Expectancy is the average result per completed trade under stated assumptions. It depends on how often you win, the average win, the average loss and costs. A figure from past trades is not a promise about the next one.

The general formula: expectancy = (win fraction × average win) − (loss fraction × average loss), using figures after costs. Gross means before costs; net means after costs. Count costs once only.

Costs move the break-even point. Go back to the 2R-win, 1R-loss model and assume every trade costs 0.1R (a teaching assumption). Each win now nets 1.9R and each loss costs 1.1R, so break-even needs 1.1 ÷ (1.9 + 1.1) = 36.67% winning trades, up from 33.33% (derived).

SEBI's data shows the same pull in real accounts. In its August 2026 study, 82.1% of individual F&O traders were loss-makers before costs in 2025-26, and 87.7% after costs: costs pushed about 5.6 more percentage points into loss (derived). Individuals paid about ₹25,000 crore in transaction costs in each of 2024-25 and 2025-26.

SEBI's July 2024 study of intraday trading in the cash market found that 71% of individual intraday traders had net losses in 2022-23, and that loss-makers added 57% to their trading losses through costs. A small sample, changing markets and losses that come in clusters can make any estimate unreliable. Positive arithmetic does not prove a lasting edge.

Correlation describes how prices move together over a chosen period. For a beginner, the easier question is: do my holdings depend on the same thing? Different names do not mean different risks.

A real example. Late on 31 December 2025, India's Ministry of Finance notified a new excise duty on cigarettes of ₹2,050 to ₹8,500 per 1,000 sticks, by length, on top of 40% GST, starting 1 February 2026. One rule hit every cigarette maker at once.

On NSE, ITC fell from ₹403.00 on 31 December 2025 to a low of ₹345.25 on 2 January 2026, down 14.33% in two sessions (derived). Godfrey Phillips India fell nearly 21% to about ₹2,185 over the same days, as reported by Outlook Money. VST Industries makes cigarettes too and faced the same new duty. Owning all three would not have spread that risk.

Diversification spreads money across different companies and different causes. It can soften one company's or one sector's problem, but it cannot remove a broad market fall. Links between holdings can change in a crisis, so do not assume past independence will last.

Look inside funds as well. Two funds can own many of the same companies, and your employer's shares plus your salary can tie your finances to one business. Group holdings by company, sector, country, funding and shared causes, then picture one event hitting several at once. The asset-allocation lesson goes further.

Portfolio heat is the total of all planned losses across open positions, each measured at its planned exit. It is not the total amount invested and not the worst possible loss. Define the exits and the capital before you use the percentage.

As an illustration, Mr. Chartist's ₹5,00,000 account holds five open positions, each with a ₹5,000 planned loss. Together that is ₹25,000, or 5% of capital before costs (derived). Five small budgets can add up to a large total.

Now a stress case (also an illustration): one shared event causes a ₹8,000 loss on every position. The total becomes ₹40,000, or 8% before costs (derived). That is not the worst case. ITC's real two-day fall of 14.33% in January 2026 shows how a gap and a shared cause can beat the plan.

Moving a stop up to the entry price does not make a holding risk-free. Costs can still leave a loss, the fill can differ and the price can gap past the level.

There is no universal 5% limit here. Any written limit should fit your financial capacity, the products and how orders really fill. Adding a position means checking the whole account again, not just its own small budget.

Averaging down means buying more after the price falls, which lowers your average purchase price. It also puts more money at risk. A lower average does not erase the loss already there.

Illustration on real ITC closing prices: buy 100 shares at ₹420.35 on 31 October 2025, costing ₹42,035. Buy 100 more at ₹363.85 on 1 January 2026, costing ₹36,385. That is 200 shares for ₹78,420, an average of ₹392.10 (derived). The quantities are an illustration.

At the 19 October 2026 close of ₹260.80, the 200 shares are worth ₹52,160: a loss of ₹26,260. Without the second purchase, the first 100 shares would be worth ₹26,080, a loss of ₹15,955. The added shares brought ₹10,305 of extra loss at the same final price (all derived, before costs and dividends).

The share count doubled here, and so did the sensitivity to every further rupee of fall. Total cost, financing and how hard it is to exit all changed. Measure them directly instead of finding comfort in the lower average.

A staged plan written in advance is different from buying more to avoid admitting a mistake. It still needs a reason, a total limit, the money to fund it and a bad-case check. Writing a plan does not make a weak business sound.

A personal review rule says when to stop opening new trades and what to check before starting again. It can use an account drawdown, repeated order mistakes or a broken limit. It is separate from an exchange's own trading controls.

As an illustration, an account falls from a ₹5,00,000 peak to ₹4,50,000 with no deposits or withdrawals. That is a ₹50,000 or 10% drawdown (derived). In this example the owner picked that point in advance as a review point. It is not a universal level to stop trading.

A pause does not abandon open holdings or pending orders. Check positions, money owed, exits, order status and settlement records. Match the real charges and fills against your notes before blaming the market alone.

Separate broken rules from losses that came from following the method. Both need a look: a flawed method followed faithfully still loses. Look at changed conditions, concentration and fills that were worse than planned.

A trading journal records the reason, planned quantity and exits, actual fills, costs, result and anything done differently. Restart only with evidence that the problem was fixed and the remaining risk is affordable. A profit target or a wish to win it back is not that evidence.

Start with the exact security, product, exchange and currency. Then name the money needed for other things, today's capital and what is already committed. No sum helps if it starts with the wrong instrument or money you do not have.

Work out quantity and purchase value. State the planned exit and its loss, allow for costs, then picture a worse fill or no exit at all. Check cash, lot size, liquidity and product rules, as the ITC examples did.

Add the new position to what you already hold and look for shared causes. Ask whether one event could hit several holdings together, as the excise notice did. The trade, the portfolio and the household's money needs should fit together.

After placing the order, check that it was accepted, how much filled, what is left and when it expires. A clicked button is not a completed trade. Keep watching what remains open.

Record what happened and review the plan with real costs and fills. Continue with the lessons on placing orders, charges and taxes, asset allocation and trading psychology. Investments in securities carry market risk, including loss of capital, and no sizing formula guarantees an outcome.
