Big data analytics, order imbalance and the predictability of stock returns

But, this doesn’t, mean companies have computers making all the trades without human involvement. Indeed, computers will perform some functions better, whereas some aspects of finance need human involvement. As time goes by, the benefits of big data will be largely impactful as business activities continue to pose a huge environmental risk and many people begin investing dependent on the impact of these businesses. Companies that fail to consider the environmental and social factors that determine the investing decisions people make will likely face risks they’re not currently thinking about. By 2016, there were an estimated 18.9 billion network connections, with roughly 2.5 connects per person on Earth. Financial institutions can differentiate themselves from the competition by focusing on efficiently and quickly processing trades.

How big data is used in trading

Algo trading is widely used and successful because it replaces human emotions with data analysis. Time-weighted average price strategy breaks up a large order and releases dynamically determined smaller chunks of the order to the market using evenly divided time slots between a start and end time. The aim is to execute the order close to the average price between the start and end times thereby minimizing market impact. Mean reversion strategy is based on the concept that the high and low prices of an asset are a temporary phenomenon that revert to their mean value (average value) periodically.

In this article we will examine how the above-listed ten industry verticals are using Big Data, industry-specific challenges that these industries face, and how Big Data solves these challenges.

  • While many contributions discuss big data in the business, organizational and management literature, more empirical work is needed to provide theoretical insights and analysis in specific business sector contexts (George, Haas, & Pentland, 2014).
  • Big data analytics allows for more accurate predictions, which in turn increases the effectiveness of managing the inherent risks that come with financial trading.
  • Latency is the time-delay introduced in the movement of data points from one application to the other.
  • Data is becoming a second currency for finance organizations, and they need the right tools to monetize it.
  • Machine learning has made incredible progress, allowing computers to make human-like decisions and execute trades at speeds and frequencies that are unimaginable for humans.

This includes data gathered from social media sources, which help institutions gather information on customer needs. Structured data consists of information already managed by the organization in relational databases and spreadsheets. As a result, the various forms of data must be actively managed in order to inform better business decisions.

What types of data are you analyzing and how does it differ from what you were looking at before the Data Revolution?

Big data is routinely tapped in the financial sector to reduce previously unknown risks as much as possible. AI has already been used to predict stock performance based on quarterly earnings calls. And while data science relied on rigid algorithms in the past, the landscape of financial data analytics nowadays is ruled by machine learning, particularly neural networks. In 2012 algorithmic trade instructions sent by both LFT and HFT accounted for over 1.6 billion shares every day (Shorter & Miller, 2014, p. 14). HFT is a form of algorithmic trading which relies on advanced technological infrastructure to compete on speed, rapid turnover rates, and high order-to-trade ratios as they leverage vast amounts of financial data (Aldridge, 2013). When using big data to predict stock market trends, a variety of data sources can be used.

There are billions of dollars moving across global markets daily, and analysts are responsible for monitoring this data with precision, security, and speed to establish predictions, uncover patterns, and create predictive strategies. The value of this data is heavily reliant on how it is gathered, processed, stored, and interpreted. Because legacy systems cannot support unstructured and siloed data without complex and significant IT involvement, analysts are increasingly adopting cloud data solutions. The world of trading has undergone a major transformation in recent years with the rise of big data technology.

How big data is used in trading

In most places, transport demand models are still based on poorly understood new social media structures. In public services, Big Data has an extensive range of applications, including energy exploration, financial market analysis, fraud detection, health-related research, and environmental protection. There may be conflicts of interest relating to the Alternative Investment and its service providers, including Goldman Sachs and its affiliates. These activities and interests include potential multiple advisory, transactional and other interests in securities and instruments that may be purchased or sold by the Alternative Investment. These are considerations of which investors should be aware and additional information relating to these conflicts is set forth in the offering materials for the Alternative Investment. Progress made in computing and analytics has enabled financial experts to analyze data that was impossible to analyze a decade ago.

Applications of Big Data in the Communications, Media and Entertainment Industry

These datasets are so enormous that common software tools and storage systems are not capable of collecting, handling, and generating inferences in plausible time intervals. Huge amounts of data are generated each day since online trading has simplified the job and it’s easier to view the market from your mobile by using an online trading platform or various stock trading applications. New innovations in artificial intelligence, analytics, and machine learning are revolutionizing how well people dealing in the financial industry can determine the impact that data has on the stock market. Unstructured data is information that is unorganized and does not fall into a pre-determined model.

Such trades are initiated via algorithmic trading systems for timely execution and the best prices. A trader may be simultaneously using a Bloomberg terminal for price analysis, a broker’s terminal for placing trades, and a MATLAB program for trend analysis. Depending upon individual needs, the algorithmic trading software should have easy plug-n-play integration and available APIs across such commonly used trading tools. Algorithm trading has been adopted by institutional investors and individual investors and made profit in practice.

The soul of algorithm trading is the trading strategies, which are built upon technical analysis rules, statistical methods, and machine learning techniques. Big data era is coming, although making use of the big data in algorithm trading is a challenging task, when the treasures buried in the data is dug out and used, there is a huge potential that one can take the lead and make a great profit. Big data in finance refers to the petabytes of structured and unstructured data that can be used to anticipate customer behaviors and create strategies for banks and financial institutions. As the financial industry rapidly moves toward data-driven optimization, companies must respond to these changes in a deliberate and comprehensive manner. HFT exists within a dynamic and fast evolving financial market where the technology infrastructure of one firm competes against another (Menkveld, 2013). However, no definition for this activity exists because the strategies they follow have different data requirements, making any generalisation across HFT firms difficult.

In this case, the trader isn’t exactly profiting from this strategy, but he’s more likely able to get a better price for his entry. It assesses the strategy’s practicality and profitability on past data, certifying it for success (or failure or any needed changes). This mandatory feature also needs to be accompanied by availability of historical data, on which the backtesting can be performed.

So each of the logical units generates 1000 orders and 100 such units mean 100,000 orders every second. This means that the decision-making and order sending part needs to be much faster than the market data receiver in order to match the rate of data. Talend’s end-to-end cloud-based platform accelerates financial data insight with data preparation, enterprise data integration, quality management, and governance. Selecting a cloud data platform that is both flexible and scalable will allow organizations to collect as much data as necessary while processing it in real-time.

Alternatively, if the business calls for a custom financial software solution, advisors and data analytics platform developers must work side-by-side to turn the company’s economic models into algorithms for the framework AIs to work with. Mathworks’ MATLAB is a data analytics platform that caters to developers and computer scientists. MATLAB enables fast testing of novel algorithms and models to Big Data in Trading optimize the creation of personalized trading strategies. Its data analytics solution encourages the automation of data pipelines such as equity trading order workflow. Big data has been used in the industry to provide customer insights for transparent and simpler products, by analyzing and predicting customer behavior through data derived from social media, GPS-enabled devices, and CCTV footage.
