Risk Review
A risk review is a regular, structured check that your position sizing, total exposure, correlation between positions and drawdown are all within pre-set limits, designed to catch risk creeping above plan before it produces a damaging loss.
Quick Answer
A risk review is a regular check on how much you could lose, not how much you have made. You verify that position sizes obey your rules, that open trades are not secretly the same bet, and that total exposure and drawdown sit within limits. Its purpose is catching risk creep before it becomes a single damaging loss.
Definition of Risk Review
Risk Review is a regular, structured check that position sizing, total exposure, correlation and drawdown all sit within pre-set limits, catching risk creep before it produces a damaging loss.
Key takeaways on Risk Review
- A risk review checks how much you could lose, not how much you have made
- Check per-trade risk and total portfolio heat, since separate bets can combine
- Watch correlation, because independent-looking positions often move together
- Keep a margin buffer to avoid forced liquidation on a volatility spike
- Enforce a pre-set drawdown limit; a breach ignored makes the review pointless
Risk Review in simple words
A risk review is a regular check-up on how much you could lose, not how much you have made. You look at whether your position sizes are within your rules, whether your open trades are secretly all betting on the same thing, how much of your capital is at risk in total, and how deep your drawdown has gone. The point is to catch risk quietly growing, bigger positions after a good run, too many correlated trades, before it turns into a loss you cannot easily recover from.
Why Risk Review matters
A risk review exists because risk tends to creep upward unnoticed, sizes drift larger after wins, correlated positions accumulate, and the biggest losses usually come from risk that was allowed to build quietly, so a periodic deliberate check keeps exposure honest.

Risk Review — professional explanation
A risk review looks at loss, not profit
Most review habits focus on returns; a risk review deliberately looks the other way, at how much you could lose. This matters because the largest account-ending losses almost never announce themselves in the profit column first, they build in the risk column, as sizes drift up, positions cluster, and leverage creeps higher during a confident stretch. Reviewing risk on its own, separately from performance, forces you to see exposure as a quantity in its own right rather than a byproduct of chasing returns. The central question is not how am I doing but how much can I lose right now if things go against me, and is that number still within the limits I set when calm.
Per-trade risk and total portfolio heat
The first layer of a risk review is per-trade risk: is each open and planned position sized so that its stop-out costs only the fixed fraction of capital you intended, typically a small percentage. The second layer is aggregate, often called portfolio heat: the sum of what you would lose if every open position hit its stop at once. Traders frequently keep each trade within limits individually while the total heat quietly exceeds what they would ever accept as a single bet. Reviewing both layers catches the case where five separate one-percent risks combine into a five-percent exposure to a single adverse market move, which is a far larger risk than any single trade suggests.
Correlation: the hidden concentration
A risk review must check correlation, because positions that look independent often move together, converting apparent diversification into concentrated risk. Long Nifty futures, long Bank Nifty calls and long a basket of high-beta stocks are, in a sharp market fall, effectively the same bet, and they will lose together on the day it matters. Correlation also tends to rise precisely in a crisis, when diversification is most needed, so positions that behaved independently in calm conditions can converge. The review asks: if the market gaps down tomorrow, how many of my positions lose at once, and is my true exposure to a single factor much larger than my position list makes it look.
Leverage, margin and the forced-exit risk
In Indian F&O a risk review must examine leverage and margin explicitly, because these introduce a failure mode beyond ordinary loss: forced liquidation. Check margin utilisation against available capital with a buffer, because a position sized to the edge of your margin can be closed out by an intraday mark-to-market swing before your thesis has a chance to play out, crystallising a loss at the worst price. Confirm that SPAN plus exposure requirements leave headroom for a volatility spike, and that a gap open would not trigger a shortfall. The prudent leverage is almost always well below the maximum the broker permits, and the review is where that gap is checked.
Drawdown and the pre-set stop-trading limit
A risk review tracks drawdown against a pre-committed limit at which you reduce size or stop trading to reassess. This matters because drawdowns are self-reinforcing: as losses deepen, the psychological pressure to revenge trade, oversize and abandon the plan intensifies, exactly when discipline is most needed. A pre-set maximum drawdown, decided when calm, acts as a circuit breaker that removes the decision from the emotional moment. The review checks current drawdown against that limit and against your recovery capacity, and it treats approaching the limit not as a failure but as the system working, protecting capital so that a bad stretch stays a setback rather than becoming terminal.
Cadence and acting on the findings
Risk review works at more than one cadence. A quick exposure check belongs in the daily routine, before and during the session, confirming per-trade risk and total heat are within limits. A fuller risk review fits the weekly or monthly cadence, examining correlation, leverage trends and drawdown over time, and asking whether risk has drifted since the last check. The review is only useful if it drives action: reducing an oversized position, closing a correlated duplicate, cutting leverage, or standing down at a drawdown limit. A risk review that notes a breach but changes nothing is theatre; its whole value is in enforcing the limits when they are inconvenient.
How professionals apply Risk Review
Professional risk desks separate the people who take risk from the systems that limit it, and they review exposure continuously: per-position and per-book limits, aggregate heat, correlation and factor exposure, leverage and margin headroom, and a hard maximum drawdown that forces a stop. They stress-test the book against gaps and volatility spikes and treat approaching a limit as the system working. This institutional discipline reflects that capital preservation is the first objective, without implying that diligent risk review guarantees against loss.
Practical example: Risk Review
Illustrative example (Indian market)
A trader with Rs 5,00,000 runs a weekend risk review. Each of their four open positions was sized to risk 1 percent, Rs 5,000, seemingly fine. But three are bullish, long Nifty futures, long Bank Nifty calls, and a basket of high-beta midcaps, so a single sharp market fall would hit all three together: the true correlated exposure is closer to 3 percent on one factor, not three independent 1 percent bets. Margin utilisation has crept to 80 percent, leaving little buffer for a volatility spike. Drawdown stands at 7 percent against a 10 percent stop-trading limit. The review's actions are clear: close or hedge one bullish position to cut correlated exposure, and reduce size to restore a margin buffer before adding anything new.
For an options seller the risk review centres on tail exposure and margin: they check SPAN plus exposure utilisation against a spike in India VIX, confirm no naked short options are held into the final hour of a weekly expiry where a gamma move can be violent, and stress-test the book against a 2 to 3 percent gap in Nifty, since Indian markets can gap on global cues before the 9:15 open, beyond where any intraday stop could act.
Advantages
- Catches risk creeping above plan before it becomes a large loss
- Reveals hidden concentration when supposedly independent positions correlate
- Checks total portfolio heat, not just each trade in isolation
- Guards against forced liquidation by keeping a margin buffer
- Turns a drawdown limit into an enforced circuit breaker, not a suggestion
Limitations
- Correlation estimates can fail in a crisis, when correlations converge toward one
- A stop can gap through its level, so measured risk is a floor not a ceiling
- It controls risk but cannot supply the edge that makes risk worth taking
- Reviewing risk without acting on breaches provides false comfort
- Tail events can exceed any pre-set limit, so no review makes ruin impossible
Why Risk Review matters in practice
- It is where the quiet build-up that causes big losses is caught early
- It keeps a bad stretch a survivable setback rather than a terminal event
Common misconceptions about Risk Review
Misconception: A risk review can prevent all losses.
Reality: No. It controls the size and build-up of risk, which keeps losses survivable, but stops can gap through their level, correlations can converge in a crisis, and tail events can exceed any pre-set limit. A risk review makes ruin much less likely, not impossible, which is why sizing conservatively still matters.
Misconception: Approaching your drawdown limit means you failed.
Reality: No. Reaching a pre-set drawdown limit and reducing size or standing down is the system working as designed, protecting capital so a bad stretch stays a setback rather than becoming terminal. Treating the limit as a discipline to honour, not a defeat to override, is what makes it effective.
Common mistakes with Risk Review
- Reviewing only returns and never checking how much could be lost
- Keeping each trade within limits while total heat quietly exceeds them
- Ignoring correlation and mistaking several similar bets for diversification
- Running margin to the edge with no buffer for a volatility spike
- Setting a drawdown limit and then overriding it when it is hit
- Noting a risk breach in the review but changing nothing afterward
Frequently asked questions about Risk Review
How is a risk review different from a performance review?
A performance review measures returns and whether you have an edge; a risk review measures exposure and whether you could be hurt. The largest losses build in the risk column, through creeping size, correlation and leverage, before they ever show in returns, so risk deserves its own dedicated check.
Why does correlation matter in a risk review?
Because positions that look independent often move together. Long Nifty futures, long Bank Nifty calls and long high-beta stocks are effectively one bullish bet in a sharp fall, so they lose together. Correlation also rises in a crisis, converting apparent diversification into concentrated risk exactly when it matters most.
How much should I risk per trade?
A common guideline is 1 to 2 percent of capital per trade, but it is a rule of thumb, not a law. The right figure depends on your edge, win rate, correlation between positions and drawdown tolerance. A risk review checks that each position is actually sized to your chosen limit.
What is a drawdown limit?
A drawdown limit is a pre-committed level of peak-to-trough loss at which you reduce size or stop trading to reassess. Decided when calm, it acts as a circuit breaker that removes the decision from the emotional moment, because the urge to revenge trade is strongest exactly when a drawdown deepens.
What is prudent leverage in Indian F&O?
Almost always well below the maximum the broker permits. Margin availability is not a measure of safe size; the SPAN plus exposure system lets a modest account control large notional exposure. A risk review checks the gap between the leverage you are using and the leverage that is actually prudent for your capital.
What should I actually check in a risk review?
Per-trade risk against your limit, total portfolio heat, correlation and factor concentration across open positions, leverage and margin utilisation with a buffer, and current drawdown against your stop-trading limit. Then act on any breach, because a review that notes problems but changes nothing provides only false comfort.
Why does risk creep up after a winning streak?
Confidence rises with wins, and traders drift into larger sizes, more positions and higher leverage without a deliberate decision. Because this build-up is gradual and feels justified by recent success, it goes unnoticed until an adverse move exposes it, which is why a periodic risk review that measures exposure objectively is so valuable.
Voice search questions about Risk Review
Natural-language questions people ask about Risk Review.
What is portfolio heat?
It is how much you would lose if all your open trades hit their stops at once. Each trade can look fine on its own while the total is way more than you would ever risk on one bet.
How much should I risk on a trade?
Often around one to two percent of your capital, but it is a rule of thumb. A risk review just checks that each trade is actually sized to whatever limit you chose.
What should I do if I hit my drawdown limit?
Reduce size or stop and reassess, as planned. Hitting the limit is the system working, protecting your capital, not a failure to feel bad about.
