Quantitative trading

Quantitative trading

The father of quantitative  analysis is Harry Markowitz, one of the first to use mathematical models in financial markets. Quantitative trading is a strategy used by institutional investors and hedge funds, but it is slowly making its way into the vocabulary of everyday retail investors. Quantitative traders use cutting-edge tools, mathematical models, and readily accessible comprehensive data to make informed trading judgments. 

What is quantitative trading? 

Quantitative trading is a market strategy that uses statistical and mathematical models to find opportunities and frequently act on them. The name of the strategy comes from the fact that quantitative analysis drives the models. It is sometimes referred to as “quant” or “quant trading.” 

Research and measurement are used in quantitative analysis to reduce complicated behavioural patterns to numerical values. It disregards qualitative analysis, which assesses opportunities based on arbitrary elements like management talent or brand power.  

Due to the high computing demands of quant trading, only large institutional investors and hedge funds have historically used it. However, in recent years, new technology has also made it possible for a growing number of independent traders to participate. 

How does quantitative trading work? 

Quantitative trading relies heavily on data and calculates the likelihood of various outcomes using statistical and mathematical models. It conducts extensive investigations and develops conclusive ideas using numerical data sets.  

This is why elite financial institutions and high-net-worth individuals have dominated the quantitative trading industry for a long time. Yet, ordinary investors are now using it more frequently. 

Hedge funds and financial organisations use quantitative trading because of their huge transactions, which might involve purchasing and selling thousands of securities and shares. Nonetheless, private investors have been resorting to quantitative trading recently.  

Programing languages are used by investors who engage in quantitative trading to harvest historical stock market data from the web. In a procedure known as the beta-testing of quantitative models, the historical data is used as input for mathematical models. 

Quantitative trading systems 

Any quantitative trading system has four key components: 

• The research entails selecting a trading strategy and assessing its compatibility with other trader strategies, which is the first step in the quantitative trading process. 

• Strategy back-testing aims to determine whether the strategy chosen in the first step is profitable when applied to historical and out-of-sample data. Positive back-testing outcomes gauge how the strategy will function in real-world situations but does not ensure success. 

• The execution system is the process by which a broker executes a list of deals that the strategy generates. Either all or a portion of the execution process may be automated. The primary elements to consider while building an execution system are the interface to the brokerage, decreased transaction costs, and performance divergence between the live system and the back-tested performance. 

• Quantitative trading involves several hazards, such as technological risks and brokerage risks. 

Pros and cons of quantitative trading 

The pros of employing these methods of quantitative trading are: 

• This style of trading seeks to determine the likelihood of a successful trade. 

• It allows for efficient stock monitoring, analysis, and trading decisions. 
• By analysing and making lucrative trading decisions using computer algorithms, quantitative approaches improve efficient trading judgments. 
• The emotions of fear and greed are eliminated, and rational decision-making is encouraged rather than relying on hunches or chance. 

The following are some of the quantitative trading strategy’s cons: 

• Due to the erratic nature of the financial markets, algorithmic models must constantly change. 
• Most quantitative models are lucrative only for the specific market type or circumstance to which they are applied. As a result, the experts must update them when market conditions change. 

Quantitative trading example 

Quantitative trading algorithms can be modified to assess various aspects of a stock depending on the trader’s analysis and preferences. Think about a trader who practises momentum investing. They can decide to create straightforward software that selects the winners when the markets are moving upward.  

The software will purchase those equities when the market recovers the next time. This quantitative trading example is quite straightforward. Normally, a complicated mix of stocks intended to maximise profits is chosen using various criteria, including technical analysis, value stocks, and fundamental analysis. An automated trading system is configured with these criteria to profit from changes in the market.
