Operational and Non-Financial Risks in Quantitative Trading
Summary
The document surveys non-market risks that can disrupt a quantitative trading firm, including model and data problems, operational failures, regulatory and legal exposure, political risk, and dependence on key personnel. It frames trade administration as one control area: staff permissions, position limits, approval by another person, and explicit rules for moving a trade through its lifecycle can reduce errors and misconduct. Political exposure may be reduced by using related instruments or markets, while infrastructure downtime can be addressed with redundancy and failover.
The most detailed discussion concerns data risk. Revisions to economic releases, exchange corrections, historical data that is not true tick data, outliers, rescaling, and corporate actions can all make research inputs differ from information available in real time. The document recommends understanding these issues and reflecting them in a model or operational safeguards. These are illustrative examples rather than a complete control framework; it gives no quantified failure probabilities, implementation specifications, or evidence comparing the effectiveness of particular mitigations.
Key ideas
- Operational risk includes failures of controls, misconduct, and disruptions to systems or data.
- Trade workflows can restrict state changes by role and require independent approval.
- Quantitative strategies should account for revised, corrected, or otherwise non-live historical data.
- Infrastructure redundancy and failover can mitigate outages in feeds or other systems.
- Political exposure may be reduced through related instruments or securities denominated in a more stable currency.

# What are some examples of non-financial risks and contingency plans? # What are some examples of non-financial risks and contingency plans? There are many online sources about common risk factors in investing and trading e.g. market risk, credit risk, interest rate risk. There are various factor models (Fama-French, Carhart) and risk management methods to mitigate them. What are examples of non-financial risk, such as hardware or network connection failure, death/injury of an employee, that quant trading firms face? Are there any decent examples of risk mitigation or contingency planning methods for such risks that are available online? ## Answer by jeebs (score 6) https://quant.stackexchange.com/a/537 To give an example of a source of risk that isn't one of the ones you mentioned but still broadly on-topic for a Quant Finance site: operational risk - for which there are many references for contigency plans. This is the domain of the back office. Trades are created (priced and analysed) by quants, executed by traders and approved by preferably at least one other person (called "four eyes approval") before being officially agreed. This is concerned with Trade Administration. A trade goes through several states with different permissions required to move a trade from one state to the next e.g. pending, approved, rejected, confirmed, cancelled, expired, with only certain transitions being allowed. Back office software can ensure that different sets of employees within a bank or other financial instution can only perform certain tasks and enforce limits on trading positions etc. The cost of the added complexity to the system is designed to minimise operational risk and generally prevent "rogue trader" scenarios. ## Answer by Ram Ahluwalia (score 6) https://quant.stackexchange.com/a/3476 There are all sorts of financial and non-financial risks. I define financial risk as all risks defined from events in the financial markets that affect all participants. Non-financial risks are all other forms of risk (including risks that a particular firm may face). Financial: - Market value risk (interest rate risk, exchange prices, equity prices, commodity prices, etc.) - Credit risk (downgrade, default, credit spread risk) - Liquidity risk Non-Financial: - Model Risk - Operational Risk (fraud, misconduct, failure of internal controls or audit systems, natural disasters) - Settlement risk - Accounting risk (changes in GAAP/IFRS and comparability issues, managed earnings, etc.) - Regulatory risk - Legal risk (counterparty does not honor a contract) - Tax risk - Sovereign risk (if you are trading EM debt for example) & Political risk - Performance netting risk - Key Man risk ## Answer by Ellie K (score 4) https://quant.stackexchange.com/a/1722 I consider market risk, credit risk and operational risk to be the three major forms of financial risk exposure. @jeebs addressed the trade settlement component of operational risk. I would also include the third bullet point that @shane gave in his answer as belonging to the category of operational risk. Another form of non-financial risk would be political risk, if one is trading in securities that are sourced from a single country e.g. commodities, or traded on a foreign exchange which may become unstable due to political turbulence. Contingency plans would be to trade the same commodity, but perhaps the futures or options on that commodity, or trade the same commodity if listed on other exchanges. Political risk can also be mitigated by investing in similar but not quite as high yielding securities. For example, if one wanted to invest in developing nations sovereign debt in the past, but have the transaction denominated in a major currency, there were Brady Bonds, which were $US denominated. The same is still true if one is willing to relinquish some return, by buying large corporation bonds from say, Mexico, but denominated in Canadian or US dollars, rather than Peso's. Finally, there is liquidity risk. If a market is not deep enough, with enough daily (or weekly) transactions, one can get stuck in a position. This can happen in any market, any security type, any where. ## Answer by Shane (score 3) https://quant.stackexchange.com/a/538 Data is the lifeblood of a quantitative strategy. So I would say that the primary operational risks facing quantitative models are related to data. Some places where this can be an issue: - Misinterpreting post-hoc data: Many economic indicators are revised on a periodic basis, and it's critical to understand what the meaning of the numbers are on a real-time basis. Similarly, some exchanges will provide price corrections, and you need to determine whether these would have been applied to your data. Lastly, some historical price data is indicative (i.e. not real tick data) because it has been scrubbed or averaged in some way. - Data outliers and changes: Data inevitably has problems due to any number of factors, ranging from outliers or errors to re-scalings (and corporate actions). - Unexpected infrastructure failures: No computer system is perfect. It's critical to understand the likelihood of a down-time, whether related to a data feed or some other aspect of your infrastructure, and either build these assumptions into your model or else mitigate these risks through redundancy and failover.
