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, 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.
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.
Purpose
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.

Layered risk checks: per-trade risk, total exposure, correlation, and drawdown, each compared against its pre-set limit.
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.
Practical example
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 it 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 mistakes
- 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
Professional usage
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.
Key takeaways
- 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
