Stop loss, R-multiple, position size, drawdown, expectancy — the words that protect capital
Published by The Retail Trader · AUG 06, 2026 · Risk Management
Risk management vocabulary feels boring, and that is exactly why most people read it last — often after one big loss. These are the terms that matter more than the entry, because staying in the market is the real edge.
The terms inside a single trade:
• Stop Loss — The price at which you accept that your idea was wrong and close the trade.
• Hard SL vs Mental SL — A hard SL is placed in the system; a mental SL exists only in your head and often slips under pressure.
• Target — The price at which you plan to book profit.
• Risk-Reward Ratio (RR) — How much you are risking versus how much you can earn. 1:2 means expecting ₹2 for every ₹1 risked.
• R-Multiple — Measuring each trade's result as a multiple of its initial risk. A ₹3 profit on 1R of risk means +3R.
• Entry — The price at which you take the position, and the reason behind it.
• Exit — The rule for getting out: target, stop, or time-based.
• Trailing Stop Loss — Moving the stop behind the price as the trade moves in your favour, so that profit is protected.
• Breakeven Stop — Moving the stop to the entry price, which makes the trade risk-free.
• Scaling Out / Partial Booking — Selling a part of the position at the target and letting the rest run.
• Invalidation Level — The point at which your entire idea is proven wrong. The stop always goes beyond this level, never according to your wallet.
The survival of the whole account, not just one trade, rests on these numbers:
• Position Sizing — Working out how many units to buy from the stop loss distance and the allowed risk. This is the real tool of risk management.
• Risk Per Trade — What percentage of capital is at risk in one trade. Many professionals keep it within 1-2%.
• Capital Allocation — How much of your total capital goes into which strategy or segment.
• Exposure — Your total market risk, with all positions combined.
• Leverage — Borrowed buying power. It multiplies losses along with returns.
• Margin Call — The broker's demand to add money or reduce positions when margin falls short.
• Max Daily Loss — The maximum you are allowed to lose in a day; once the limit is hit, the screen goes off.
• Drawdown — The fall from the peak to the current value, in percentage terms.
• Max Drawdown — The biggest fall so far. This number tells you whether a strategy is emotionally bearable.
• Recovery Math — After a 50% loss, you need a 100% gain to get back to break-even. That is why avoiding a big loss matters more than scoring a big win.
• Risk of Ruin — The probability of wiping out the entire account, which rises quickly with over-leverage.
These show whether your method is actually working:
• Win Rate — The percentage of trades that were profitable. This number alone says nothing.
• Average Win / Average Loss — The size of a typical win and a typical loss. Even a low win rate works if the wins are big.
• Expectancy — The average expected result per trade. Without positive expectancy, increasing the sample size only increases the losses.
• Profit Factor — Total profit divided by total loss. Above 1 means the system is net positive.
• Backtesting — Testing rules on old data.
• Forward Test / Paper Trading — Following the rules in the live market without putting in money.
• Sample Size — The number of trades after which you draw a conclusion. 10 trades tell you nothing.
• Edge — The small statistical advantage that makes money over the long run.
• Equity Curve — The graph of your account value. Its shape says everything about the strategy.
• Trading Journal — A record of every trade: reason, entry, exit, mistake. This is what shows you where the money is being lost.
Holding several positions at once brings new kinds of risk:
• Diversification — Spreading across different stocks and sectors, so that a shock in one place does not sink the whole account.
• Correlation — Two positions moving together. Buying five bank stocks is not diversification, it is the same bet five times.
• Concentration Risk — Having too large a share of capital in one place.
• Beta — How much a stock moves relative to the index. A beta of 1.5 means roughly one and a half times the index's movement.
• Systematic Risk — The risk of the entire market, which diversification cannot remove.
• Unsystematic Risk — The risk specific to one company or sector, which diversification reduces.
• Overnight Risk / Gap Risk — News that arrives after the market closes and can open the next day beyond your stop loss.
• Event Risk — Extra volatility around scheduled events such as results, the budget, or policy meetings.
• Black Swan — A very rare, very large and unexpected event. This is why position size is kept small.
• Liquidity Risk — Being unable to find an exit when you need one, especially in small stocks.
Cost is also a kind of risk, because it is charged on every trade for certain — unlike profit:
• Brokerage — The broker's charge, which differs for delivery and intraday.
• STT (Securities Transaction Tax) — A government tax levied on the trade value.
• Exchange Transaction Charges — The exchange's own charge.
• GST and Stamp Duty — Statutory charges levied on brokerage and turnover.
• DP Charges — The per-scrip charge applied when you sell shares from your demat.
• Total Round-Trip Cost — The charges of entry and exit combined. This is the number that pushes your breakeven higher.
• Slippage Cost — The difference between the expected price and the actual fill, hidden in every fast trade.
• Overtrading Cost — More trades mean more charges. Many small traders lose not to the market but to their own turnover.
Placing a stop loss and placing it in the right spot are two different skills. Here are the methods and their trade-offs:
• Structure-Based SL — A stop beyond the swing low or high where your idea gets proven wrong. The most logical, but gives a different width every time.
• ATR-Based SL — A multiple of the stock's own average movement. A volatile stock automatically gets more room.
• Percentage SL — A fixed percentage below the entry. Simple, but it completely ignores the stock's volatility.
• Time-Based Exit — If the trade has not moved within the set time, get out — even if the stop was not hit.
• Volatility Stop — A stop that automatically widens when volatility rises and tightens when it falls.
• Tight vs Wide SL — A tight SL means a small loss but gets hit more often; a wide SL means it is hit less often but the loss is bigger. Position size equalises the two.
• SL Hunting — Stops piling up just beyond obvious levels, and price running to them and then reversing.
• Gap Through SL — On overnight news, price opens beyond your SL and the exit lands far from the stop. This is why overnight size is kept small.
• SL-M in Fast Market — In a fast move an SL-M does execute, but with slippage; an SL-limit protects the price, but if it does not execute the position stays open.
• No-Trade Zone — The situation where the logical stop is so far away that taking a proper size is simply not possible. The right answer is to skip the trade, not to shrink the stop.
And the numbers that show what a year of hard work actually produced:
• Absolute Return — The total percentage gain or loss, with no account of time.
• CAGR — The compounded annual return, which makes it possible to compare different time periods.
• XIRR — The correct return when money was put in and taken out at different times.
• Benchmark Comparison — Comparing your return with an index such as the Nifty. A return below the index means your effort gained you nothing.
• Alpha — The extra return above the benchmark.
• Risk-Adjusted Return — Looking at return in light of the risk taken, because double the return from double the leverage is no achievement.
• Sharpe Ratio — Return divided by volatility. A system with steady returns has a higher Sharpe.
• Maximum Consecutive Losses — How many losses in a row have occurred. This number tests your mind more than your position size.
• Largest Single Loss — The biggest loss so far. If it is many times your average loss, a rule was broken somewhere.
• Average Holding Period — How long a trade is held. It tells you what style of trader you actually are, whatever you call yourself.
• Turnover Ratio — How much trading volume you did relative to your capital. Higher turnover means higher charges, whatever the result.
In one line: the entry tells you how much you can earn, and risk management tells you how many days you will get to play. The second matters more than the first.
