Quantitative Methods
Systematic, data-driven investment strategies using mathematical models and algorithms
Momentum Investing
Momentum investing is a systematic quantitative strategy that exploits the persistent tendency of assets with strong recent performance to continue outperforming in the near term. This well-documented market anomaly, first systematically studied by Jegadeesh and Titman (1993), has been observed across multiple asset classes, time periods, and geographic regions over three decades of empirical research. The strategy is fundamentally based on the principle that assets exhibiting strong price trends over the past 3-12 months will continue to outperform, while underperforming assets will continue to lag behind their peers.
The theoretical foundation of momentum investing rests on behavioral finance explanations, including investor underreaction to new information, herding behavior, and the disposition effect. These psychological biases create predictable patterns in asset returns that systematic strategies can exploit. Key implementation considerations include formation period selection (6-12 months optimal), signal construction using price momentum, relative strength, and earnings momentum metrics, and careful attention to transaction costs and market impact.
The strategy performs best during trending markets with low volatility, but struggles during market crashes and high-volatility periods. Risk management is critical, as momentum strategies are prone to momentum crashes—sharp reversals during market stress that can cause drawdowns of 20-40%. Effective risk controls include volatility targeting, diversification, and market regime filters.
Mean Reversion
Mean reversion strategies capitalize on the fundamental principle that asset prices tend to oscillate around their long-term average or mean value. When prices deviate significantly from this mean—either too high or too low—mean reversion strategies bet on prices moving back toward equilibrium. This approach stands in contrast to momentum investing, assuming that extreme price movements are temporary and that markets will correct themselves through arbitrage forces and natural price discovery mechanisms.
The strategy is based on statistical frameworks including stationarity tests (Augmented Dickey-Fuller), cointegration analysis for pairs trading, and half-life calculations to measure reversion speed. Mean reversion works best in range-bound markets with clear support and resistance levels, where prices oscillate within defined bands. Key implementation techniques include pairs trading (identifying cointegrated securities), statistical arbitrage (exploiting temporary mispricings), and volatility-based position sizing.
The strategy requires careful attention to transaction costs, as frequent rebalancing may be necessary to capture reversion opportunities. Risk management is essential, as mean reversion can break down during strong trending markets, leading to significant losses. The strategy performs best during choppy, range-bound markets but struggles during strong trending periods when prices continue moving away from the mean.
Factor Investing
Factor investing represents a systematic approach to portfolio construction that targets exposure to specific return drivers or risk factors that have been empirically shown to generate excess returns over long time horizons. This methodology, rooted in the Fama-French multi-factor models and modern portfolio theory, seeks to capture the risk premia associated with factors such as value, momentum, quality, low volatility, size, and profitability. Unlike traditional active management, factor investing uses transparent, rules-based methodologies to construct portfolios that systematically tilt toward desired factor exposures.
The strategy has gained widespread adoption among institutional investors, with assets under management in factor-based strategies exceeding $2 trillion globally. Factor investing offers several key advantages: transparency in portfolio construction, lower costs compared to active management, diversification benefits through exposure to multiple uncorrelated factors, and the ability to customize factor exposures to match specific investment objectives or risk preferences.
Implementation typically involves selecting target factors based on investment objectives, constructing portfolios using factor scores and optimization techniques, and managing factor exposures through rebalancing and risk controls. Key considerations include factor selection (choosing factors with strong empirical support), portfolio construction methodology (equal weighting, risk parity, or optimization-based), and factor timing (static vs. dynamic factor allocation). The strategy requires sophisticated risk management to avoid over-concentration in specific factors and to manage factor-specific risks such as value traps or momentum crashes.
Statistical Arbitrage
Statistical arbitrage represents one of the most sophisticated quantitative trading strategies in modern finance, employing advanced mathematical models and statistical techniques to identify and exploit temporary pricing inefficiencies between related securities. Unlike traditional arbitrage, which seeks risk-free profits from price discrepancies, statistical arbitrage accepts some risk in exchange for more frequent trading opportunities. The strategy typically involves identifying pairs or groups of securities with historically stable relationships, then trading on deviations from these relationships with the expectation that prices will revert to their historical norms.
The theoretical foundation of statistical arbitrage rests on the law of one price and cointegration theory, which suggest that related securities should maintain stable price relationships over time. When these relationships deviate temporarily due to market inefficiencies, behavioral biases, or microstructure effects, statistical arbitrage strategies can profit from the expected reversion. The strategy has gained significant popularity among quantitative hedge funds and institutional investors, with assets under management in statistical arbitrage strategies estimated to exceed $100 billion globally.
Implementation requires sophisticated infrastructure, real-time data processing, and robust risk management systems. Key components include pair selection based on correlation and cointegration, signal generation using z-scores and spread analysis, and portfolio construction with risk limits. The strategy performs best during normal market conditions when correlations are stable, but can struggle during market crises when relationships break down. Effective risk management is essential, as structural breaks can cause significant losses.
Machine Learning / AI
Machine learning and artificial intelligence are revolutionizing quantitative finance, enabling the discovery of complex patterns in financial data that traditional methods might miss. ML strategies use algorithms to identify non-linear relationships, process vast amounts of unstructured data, and adapt to changing market conditions. Techniques include neural networks for return prediction, random forests for feature selection, LSTM/GRU for time series forecasting, reinforcement learning for portfolio optimization, and natural language processing for sentiment analysis.
The strategy's appeal lies in its ability to process vast amounts of data and identify patterns that may not be apparent to human analysts or traditional quantitative models. Machine learning can incorporate alternative data sources such as satellite imagery, social media sentiment, credit card transactions, and web scraping data, providing insights that traditional fundamental or technical analysis cannot capture. This data advantage can translate into superior risk-adjusted returns when properly implemented.
However, ML strategies face significant challenges including overfitting, model interpretability, and the need for large amounts of high-quality data. Successful implementation requires sophisticated infrastructure, data engineering capabilities, and robust validation frameworks. The strategy can achieve Sharpe ratios of 1.0-2.0 when properly implemented, though overfitting and data quality remain key challenges. Risk management is critical, as ML models can fail during regime changes or when training data becomes stale.
Pairs Trading
Pairs trading is a market-neutral relative value strategy that involves simultaneously buying and selling two correlated securities when their price relationship deviates from its historical norm. The strategy requires identifying pairs with high historical correlation (typically > 0.7) and cointegration, ensuring that the price relationship is stable over time. When the spread between the two securities widens beyond historical norms, traders short the outperformer and go long the underperformer, profiting when the spread reverts to its mean.
The strategy is based on statistical frameworks including cointegration tests (Engle-Granger, Johansen) to identify pairs that move together over time, and half-life calculations to measure reversion speed. Pairs trading works best in range-bound markets with stable correlations, where relative value opportunities are most apparent. Key implementation techniques include careful pair selection, spread monitoring using z-scores, and position sizing based on volatility and correlation stability.
Historical research has shown that pairs trading strategies can generate annualized returns of 6-12% with Sharpe ratios of 1.0-1.5, though these returns decline significantly after accounting for transaction costs. The strategy requires continuous monitoring of pair relationships, as correlations can break down during market stress or when fundamental factors change. Risk management is essential, as pairs can decouple permanently during structural breaks, leading to significant losses.
