What is Quantitative Trading? Meaning, Benefits & Drawbacks

Have you ever wondered how many financial institutions and hedge funds make decisions to buy or sell stocks or other financial instruments in the stock market? It may or may not come off as a shocker, but most of these financial firms don’t have a person staring at charts, ready to press the buy or sell button.

 Instead, they rely on an algorithmic online share trading approach called quantitative trading. In this article, we will explore what quantitative trading is; we will delve into its various facets, understand its pros and cons, and provide insights on how to get started with quantitative trading in India.

What is Quantitative Trading?

Quantitative trading — also known as algorithmic trading, algo trading, or quant trading — is a strategy that relies on quantitative analysis to make investment decisions. What this means is quantitative trading uses computer programs, mathematical models, and statistical analysis to perform trades; no need for someone to stare at charts and press the buy and sell button. 

Instead of relying on human intuition and analysis, a quantitative trader employs computer algorithms to analyse market data, identify patterns, and execute trades automatically. The computer programs can analyse vast amounts of data in real-time and can swiftly react to market signals — at speeds beyond human capabilities.

Steps of Quantitative Trading

Quantitative trading involves several key components that work together to facilitate the decision-making and execution process. 

Strategy Development 

Quantitative traders dedicate plenty of time to perfect the strategy — from which the algorithm is derived — for the best profit-generating outcomes. The algorithm is designed using statistical analysis, machine learning techniques, and mathematical formulas based on various kinds of data. The quantitative model may focus on executing trend following strategies, mean reversion, statistical arbitrage, or high-frequency trading. 

Backtesting the Algorithm 

Before putting the trading strategy into action in the live market, it is essential to conduct extensive backtesting. Backtesting is a process that entails finding the efficiency of the strategy in generating profits by applying it to historical data. This helps traders refine their models and identify any flaws or weaknesses before risking real capital.

Execution

Once a strategy is deemed viable, it is implemented in the live market. Its execution is mostly fully automated; some strategies may be semi-automated. The trading platforms and software to execute trades automatically are a lot more advanced than the trading apps you come across as a regular retail investor. These platforms allow for precise order placement, efficient trade execution, and risk management techniques such as stop-loss orders and position sizing.

There are numerous quantitative trading strategies used by traders around the globe; however, the most common ones include trend following, trend following, mean reversion, statistical arbitrage, and high-frequency trading (HFT). 

Trend Following: This strategy aims to identify trading opportunities and execute trades in the direction of the prevailing trend. 

Mean Reversion: The Mean reversion strategy assumes that prices will eventually return to their average or mean values. The algorithm is constructed to execute trades based on this theory.  

Statistical Arbitrage: This strategy involves scanning an array of data and identifying pricing discrepancies between related securities to perform arbitrage trades. 

High-Frequency Trading (HFT): HFT strategies involve executing trades at instantaneous speeds to exploit small price discrepancies. HFT traders use powerful computers and low-latency connections to the exchange to gain an advantage in speed. 

Benefits of Quantitative Trading

1. Quantitative trading, by virtue of its algorithms, allows traders to execute trades at extremely high speeds.
2. Complementing the high execution speeds are accurate and precise executions without errors.
3. Moreover, quantitative trading is free from human emotional interventions and rash decision-making. 
4. Algorithms are able to assess a substantially large pool of market data as compared to manual scanning. 
5. Lastly, in the long run, this approach can prove to be cost-effective. 

Drawbacks of Quantitative Trading

1. Quantitative trading models must evolve and adjust constantly due to the dynamic, volatile nature of financial markets.
2. Moreover, most algo trading strategies are only suitable for a specific market condition; they must be modified to work effectively in another market condition.
3. A quantitative trader must possess the skills to program algorithms and evaluate mathematical models.
4. Another major drawback is perhaps the high initial investment cost that is required to get started. 

How to Learn Quantitative Trading? 

If you wish to learn quantitative trading, know that there are no shortcuts; you will have to dedicate time and effort towards learning maths and statistics as well as computer languages to program algorithms. Along with this, obviously, you must have a strong understanding of how financial markets work as well. Lastly, you could even read books on qualitative trading. 

Conclusion

Quantitative trading has revolutionised the financial industry by leveraging mathematical models and advanced algorithms to make trading decisions. By eliminating emotional biases and relying on data-driven analysis, quantitative trading offers speed, efficiency, and objective decision-making. Although it is not without its drawbacks, which results in a high barrier to entry, it is proven to be widely effective if implemented properly.
