The Importance of Risk Management in Systematic Trading

Systematic trading success requires both a positive expectancy strategy and effective risk management to preserve capital and enable compounding.

The Importance of Risk Management in Systematic Trading
Systematic trading requires effective risk management to preserve and compound capital over time.

Successful systematic trading relies not just on having a strategy with positive expectancy, but also on effectively managing risk.

The key role of risk management in systematic trading is to protect the trading capital from significant drawdowns, and enable long-term compounding of returns. Drawdowns refer to the decline in the value of the trading account from its peak value. The higher the drawdown, the more difficult it becomes to recover the losses, and eventually, the trading account may be wiped out.

Here are some key aspects of risk management to consider when running a systematic trading strategy like Alpha Signals:

Progressive Exposure

Progressive exposure is a risk management technique where a trader gradually increases their position size or risk exposure as a trade moves in their favor. The main idea behind progressive exposure is to limit potential losses while allowing profitable trades to run and maximize gains.

Progressive exposure allows traders to manage their risk by starting with a smaller position and only increasing it when the trade shows signs of success. This approach can help limit losses during losing trades while allowing profitable trades to generate larger gains.

Setting Stop Losses

A stop loss is a predetermined price at which a losing trade will be exited to prevent further losses. All trades should have a stop loss level defined before entry. The stop level is placed at a price that invalidates the trade premise. While setting stops too tight can lead to being stopped out prematurely, setting them too wide exposes too much capital to loss. Optimizing stop placement is key.

Correlation and Diversification

Diversifying trading strategies, markets, and timeframes can help smooth equity curves and improve risk-adjusted returns. However, it's important to be aware of correlations. During periods of market stress, correlations between normally uncorrelated assets can increase dramatically. Understand how your strategies and positions may be correlated.

Preparing for Drawdowns

Even high expectancy strategies suffer drawdowns - periods of losses or underperformance. Long losing streaks are part of trading. It's crucial to size positions so that expected drawdowns are tolerable and don't threaten the existence of the trading account. Having ample capital to withstand worst-case scenarios is a must.

Reducing Leverage

Using excess leverage drastically increases risk of ruin. If a highly leveraged strategy encounters a rough patch, the drawdowns may be catastrophic. It's prudent to utilize conservative amounts of leverage and combine it with sound position sizing. This provides a good balance of boosting returns while controlling risk.

Stress Testing and Backtesting

It's important to consider how a strategy will perform in varying market environments. Stress testing a system by seeing how it would have performed during historical periods of market turmoil can provide valuable insight. If a systematic strategy would have blown up in 2008 for example, it may be wise to revaluate.

The Alpha Signals strategy integrates these risk management principles to target consistent gains while defending against downside. By systematizing both the entry and exit rules as well as the risk parameters, we aim to achieve robust, risk-adjusted returns over the long run.

Of course, even the best risk management can't eliminate risk entirely. But it can turn the odds in our favor and enable the powerful force of compounding to work its magic over time.
