TK Tanmay Kurtkoti Founder & CEO, RupeeCase ⏱ 14 min read ⟳ Updated 14 Jun 2026 ◆ Advanced Systematic investing doesn't eliminate risk. It manages it differently | by making risk decisions explicit and pre-specified, rather than ad hoc and emotional. This module covers the main risk types that systematic equity investors face and the controls that actually help. The key distinction: risk management in systematic investing is almost entirely done at the *strategy design* stage, not at the trade execution stage. By the time you're looking at a portfolio and deciding whether to trade, almost all risk decisions should already be encoded in the rules. ## The six risks that actually matter Concentration Risk Too much capital in a single stock, sector, or theme. A 50% position in one stock that goes to zero halves your portfolio regardless of how the other 49% performed. ✓ Control: single-stock cap (8 to 10%), sector cap (25 to 35%) Factor Risk Excessive exposure to a single factor | momentum, value, etc. Pure factor strategies have the factor's crash risk with no offset. All 30 momentum stocks crash together in a momentum crash. ✓ Control: multi-factor diversification, combining low-correlated factors Liquidity Risk Positions too large relative to the stock's daily trading volume. Exiting the position in a stress event moves the price against you | you sell at much worse prices than expected. ✓ Control: max 5 to 10% of ADV per position. Nifty 500 minimum liquidity filter. Model Risk The signal or backtest is wrong | overfitted, contains a bug, or relies on data that isn't available at decision time. All the discipline in execution doesn't save a broken strategy. ✓ Control: out-of-sample testing, robustness checks, economic rationale requirement Drawdown Risk The strategy's peak-to-trough loss exceeds what you can emotionally or financially tolerate. Even historically validated strategies can have 35 to 45% drawdowns. If you need the money before recovery, you're forced to lock in the loss. ✓ Control: invest only money you can lock up for 5+ years. Size position relative to personal drawdown tolerance. Regulatory / Corporate Event Risk SEBI regulatory changes, promoter fraud, delisting, or sudden trading halt in a held stock. Rare but severe. DHFL, Yes Bank, and Unitech demonstrated this risk in Indian markets. ✓ Control: position size limits, quality filter screens, broad universe (Nifty 500 vs concentrated small-cap) ## Stop-losses in systematic strategies Stop-losses are a common risk management tool | automatically selling a stock when it falls X% from purchase price. For discretionary investors, they're useful. For systematic factor strategies, they're usually counterproductive. Here's why: in a momentum strategy, you're already scheduled to sell a stock when it drops below the top-30 rank on the next rebalance date. A stop-loss effectively adds a discretionary override | "sell this stock before the scheduled rebalance if it falls 15%." This introduces: * **Whipsaw risk** | you sell on a 15% dip, the stock recovers and re-enters the top-30 before the rebalance, you've crystallised a loss unnecessarily * **Higher turnover and costs** | more trades, more costs, more tax events * **Inconsistency with the backtest** | your backtest probably didn't include stop-losses. Adding them in live trading means you're running a different strategy than what was tested The systematic strategy's rebalancing mechanism IS the stop-loss. If a stock falls far enough to drop out of the top 30 by rank, it gets sold on the next rebalance. This is a cleaner, less expensive, and more consistent approach than arbitrary percentage-based stop-losses. ## Drawdown limits | the one legitimate override There is one scenario where overriding a systematic strategy is genuinely rational: when the portfolio drawdown has exceeded your pre-specified personal limit. The logic: you invested money in a systematic strategy based on the assumption that you could hold through a 35% drawdown (based on the historical maximum). If the strategy draws down 45% | beyond what was historically experienced and beyond what you modelled | this is information that wasn't in the backtest. The strategy may be behaving differently than expected. **The correct protocol:** Before deploying any systematic strategy, decide: "What drawdown, sustained for how long, would cause me to exit?" Specify this in writing, in advance. Example: "If the strategy draws down more than 40% from peak and remains below -30% for more than 6 months, I will reduce allocation by 50% and reassess." Having a pre-specified rule means this decision is also systematic | not made in panic at the bottom. **What NOT to do:** Override the strategy every time it underperforms the market for a few months. This is not risk management | it's performance chasing disguised as prudence. The most common way investors destroy the value of a systematic strategy is by adding discretionary overrides during normal drawdown periods that are well within the strategy's historical parameters. ## Allocation sizing as risk management The most powerful risk management lever is often the simplest: how much of your total investable assets do you put into any single systematic strategy? * A ₹50 lakh portfolio with 100% in a momentum strategy is very different from 50% in momentum + 50% in a fixed income fund * The right allocation depends on your investment horizon, income stability, and actual risk tolerance | not your stated risk tolerance * A common framework: allocate no more than you could watch fall 50% without needing to sell for living expenses Risk monitoring on RupeeCase RupeeCase shows **live risk metrics** for any active strategy: current drawdown from peak, days in drawdown, sector concentration, largest single-stock weight, and daily Value-at-Risk estimate. The system alerts you if any constraint (sector cap, stock cap) is approaching its limit before the next scheduled rebalance. Risk management is a dashboard feature, not an afterthought.

Controlled through position caps and sector limits. Liquidity riskThe risk that a position cannot be exited without significantly moving the price. Controlled by limiting position size to a fraction of the stock’s average daily traded volume. Model riskRisk that the strategy’s signal or backtest is incorrect, due to overfitting, data errors, or look-ahead bias. Controlled through out-of-sample testing and economic rationale. Drawdown limitA pre-specified threshold for portfolio loss from peak, beyond which the investor will reduce allocation or reassess. The only legitimate basis for a systematic strategy override. Average Daily Volume (ADV)The average daily traded volume of a stock. Position sizes should typically not exceed 5 to 10% of ADV to maintain adequate liquidity. TK Why I wrote this Risk management is the thing that keeps you in the game I’ve spent 17 years building systematic strategies, first at institutional desks, then at my own fund, and now at RupeeCase. The single biggest lesson from all of that time isn’t about alpha or factor selection. It’s about risk management. Every strategy I’ve seen blow up, mine included, early in my career, blew up because of inadequate risk controls, not because the signal was wrong. When I built RupeeCase, I made risk monitoring a first-class feature, not an afterthought. The platform shows you live drawdown, sector concentration, single-stock weight, and alerts when constraints approach their limits. Because the best time to manage risk is before a crisis, not during one. If this path has taught you anything, I hope it’s that portfolio construction isn’t about picking winners, it’s about building a system that survives everything the market throws at it. Path 4 is done. You now understand MPT, position sizing, rebalancing, performance measurement, and risk management. That’s a real foundation.
