It is no secret that technology now plays an integral part in investment strategies and even the process of placing orders. This has led to increased demand for quantitative investment strategies, which rely heavily on mathematical and statistical models to make unbiased investment decisions. In theory, these investment strategies are relatively straightforward, but they require intense computing power and statistical data in practice.

 

Key components and characteristics

 

To understand the potential of quantitative investment strategies, it's essential to know the key components and characteristics.

 

Data-driven analysis

 

In many ways, quantitative investment strategies are based on the principle that history repeats itself. For example, modern-day systems analyse vast sets of historical and real-time data to identify patterns, correlations, and relationships that may not be immediately obvious. This data can include market prices, company financials, economic indicators, and various alternative data sources. If it can be analysed, it can be used!

 

Quantitative models

 

The term quantitative models is all-encompassing, covering simple statistical analysis down to highly complex machine learning algorithms that can adapt and change in line with market conditions. However simple or complex, the idea is the same - the use of mathematical models to predict market behaviour, assess risk, and even predict investor behaviour. Big Brother is watching!

 

Systematic approach

 

While quantitative investment strategies are based on vast amounts of data, they all benefit from the removal of emotional bias and human subjectivity. Each strategy revolves around a rule-based approach to investment, which is hardcoded into algorithms and based on pure statistical data. There is no favouritism or conscious or subconscious bias, which can be challenging sometimes, especially when you see a particular scenario emerging.

 

Risk management

 

One of the often overlooked benefits of quantitative investment strategies is the ability to manage risk and exposure to mitigate potential downside. Many people automatically assume that any element of quantitative investment is high risk when this is not necessarily the case. Inbuilt complex hedging strategies will automatically kick in on enhanced market volatility or a sharp movement up or down.

 

High-frequency trading

 

High-frequency trading poses a significant challenge for regulators, representing the rapid evolution of automated systems that seize split-second investment opportunities with lightning speed. In today's financial landscape, these automated systems not only execute trades but also continually refine their strategies through machine learning and advanced AI technologies.

 

They excel at identifying market inefficiencies and price discrepancies; all based on predefined algorithms and real-time market signals. This convergence of technology and finance highlights the dynamic nature of modern trading, where speed and intelligence intersect to influence market dynamics.

 

Factor investor

 

Not one of the more commonly discussed quantitative investment strategies; factor investment revolves around an array of individual factors such as value, momentum, and trading sizes. Whether identifying price trends that have broken into new territory, strong momentum, or a sudden increase in trading sizes and volume these automated trading processes can be pre-programmed to react at varying levels of sensitivity.

 

The combinations are endless due to the number of factors impacting share price movements in the short, medium and longer term. Whether looking to identify individual characteristics, which can be subject to false positives, or a combination of factors, which may see you enter the market after a trend has being established; this is a fascinating area of investment.

 

Backtesting and optimisation

 

Even though modern-day dealing technology involves vast computing power and complex algorithms, backtesting and optimisation allow you to test new theories before "going live." This ensures that you are as optimised as possible when you click the button and put your money at risk. However, as many investors will testify, nothing is ever certain in the world of investment, with markets, investor sentiment, and trends changing on a regular basis.

 

Summary

 

While regulators are concerned about the impact of quantitative investment strategies on investment markets, they are subject to a degree of control, and surprise, surprise, they don't always get it right. The algorithms are based on vast historical data and may be ill-prepared for unexpected/new trends and scenarios. In reality, there is little that stock markets haven’t experienced since their inception but you just never know!
