Investment - Fintech Application -​High Frequency Trading (HFT) 
A specific type of algorithmic trading known as "high-frequency trading" (HFT) gathers a lot of data from both conventional and unconventional sources and uses it to automatically conduct trades when certain criteria are met, such mispricing. Within milliseconds, the system routes trades to ultra-high-speed, low-latency networks. The fragmentation of conventional trading venues has made it easier for HFT algorithms to arise, which can take advantage of minute, fleeting price variations between exchanges. 

For instance, it's believed that HFT drives 50% of trade volume in the United States. These systems operate at such fast speeds that a computer may analyze, process, and complete a deal in just 10 milliseconds. Because of this, some businesses place their servers in close proximity to important exchanges in an effort to shave milliseconds off the time it takes to complete a trade.

Investment - Fintech Application - Algorithmic and Automated Trading
The computerized purchase and sale of financial products in conformity with predetermined regulations and norms is known as algorithmic trading. It is frequently used to put trading techniques into practice in institutional and retail settings.

Large orders can be executed by institutions using algorithmic trading; they can be divided into smaller portions to minimize market impact and executed on several separate trading platforms to obtain the best price. These algorithms may constantly adjust and modify their execution approach throughout the day in response to shifting volumes, pricing, and volatility in the market.

Institutions are not the only ones that use algorithmic trading. A large number of investing businesses provide retail funds with fully automated trade execution and decision-making. This kind of fund can employ a straightforward technical analysis technique in which transactions are made in accordance with moving averages and trading volumes. It is simple to automate and program these rules.

Investment - ​Fintech Application - Natural Language Processing (NLP) 
Put succinctly, natural language processing (NLP) is a collection of methods that starts with converting unstructured textual data into structured (machine-readable) data, which is subsequently categorized or clustered to extract relevant information.

Stock Sentiment Analysis: To swiftly and thoroughly respond to the question, "Does the stock market perceive this news as good or bad for the company's stock price?" natural language processing (NLP) is used to categorize company news into "positive" or "negative" sentiment. The timing of stock purchases and sales can be improved by using sentiment analysis in addition to analysts' predictions and valuation models.

Theme Extraction and Identification 
NLP can be used to swiftly extract and cluster information that exposes underlying trends or themes from the regulatory filings and quarterly reports of many corporations, including the S&P 500 Index companies. These include problems with the supply chain, narrowing profit margins, or declining consumer demand. These topics could then serve as the foundation for investment or trading strategies.

Fintech Applications - Big Data 
Every day, analytical technologies analyze vast volumes of personal data to determine client behavior, which is then included into the decision-making process. Fintech apps, automated/algorithmic trading, automated advising and robo-advisers, mobile banking, decentralised finance (DeFi), and crypto assets are a few examples of the various forms of intelligent automation applications. 

Examining Big Datasets
Why do social media businesses offer services that are 'free'? They aren't truly free, is the explanation. Large volumes of personal data, including information about our likes and dislikes, where we travel and how we get there, and our buying patterns, are how we pay for them.

Financial analysts now evaluate more than just market indications, financial accounts, and economic statistics. Additionally, they go in-depth with the narratives presented by non-traditional data from non-traditional sources. These sources generate massive amounts of data that need to be incorporated into the decision-making process. Fintech assists with this process by creating analytical tools.

Big  data 
Big data, also referred to as alternative data, includes information produced by individuals, corporations, governments, financial markets, sensors, and the "Internet of Things." 

Over the past ten years, there has been an explosion in big data, particularly in the form of unstructured data from online news sites, social media, email and text traffic, and other electronic sources. Big data is being used by investment professionals more and more in their decision-making as they combine unstructured and structured data to enhance their financial models and projections.

Big data has various features that set it apart from ordinary data. Volume, variety, velocity, and veracity are the four main areas of distinction, or the four Vs.

Investment - Fintech 
​Fintech is the term for innovation in the financial services sector that is driven by technology. Artificial intelligence is also a component of fintech and speeds up financial planning, business lending, payments, and investment advice.

Fintech
Fintech, in its broadest definition, is innovation in the financial services sector driven by technology. While mundane tasks like data processing (as opposed to data analysis) were automated in the early stages of fintech, the current emphasis is on technical advancements that have an effect on the creation and provision of financial services.

Fintech also refers to the larger industry that these businesses are a part of as well as the businesses themselves, many of which are brand-new, start-ups that are working on creating these technologies. Traditional business models and well-established financial services firms are facing serious competition from these innovations.

Fintech has developed into apps that use sophisticated machine learning algorithms to make decisions. With these algorithms, computer programs may "learn" how to do tasks over time. Modern computer systems are capable of far more than humans can in certain situations. Fintech has brought about numerous changes to the financial services sector, including the creation of new payment, financial planning, business loan, and investment advisory systems.


Fintech components are frequently not well separated from one another. Algorithmic trading software is created using AI, and automated trading systems that find the best liquidity at the best price enable robo-advisers.

Artificial  intelligence (AI) 
What does artificial intelligence actually mean? When artificial intelligence (AI) first emerged, it was usually used to describe robots' capacity for problem-solving and cognitive abilities that are more akin to those of humans. These days, it's commonly understood to refer to machines operating within the framework of the intelligence they have continuously enhanced through data collection, implying the capacity for adaptation and learning.

Evaluation of Credit
AI determines if a client qualifies for a loan and recommends the best kind based on their situation. When it comes to helping the historically underbanked and unbanked, this is especially crucial. In this situation, using AI can cut losses from bad loans by about 20%.

Fraud Identification
An AI study of the cardholders' spending patterns sets off the automated calls that they receive when their credit card issuer detects odd activity. AI applications that are crucial include detecting money laundering and preventing cybercrime.

AI for risk management is used to analyze unstructured data, or information that is not organized or has a pre-established data model, and to spot trends and warning signs of danger.

Trading AI is frequently used in algorithmic trading programs. There are fully automated investment funds that use artificial intelligence (AI) to make and carry out trade decisions.

Artificial intelligence (AI) in personalised banking takes the shape of chatbots and virtual assistants that use natural language processing (NLP) to provide appropriate financial advice and provide round-the-clock client care.

Automation of Processes
Many tedious, repetitive, or time-consuming operations, like evaluating loan applications, where human error is frequent, can be automated by AI.

AI and ethics 
Human bias can be decreased via AI-based process automation since it lowers human mistake. Is it accurate to state, though, that AI is impartial? What ethical issues also come up with the application of AI?

Prejudice
Since data is the foundation of AI systems, it is possible—though probably unintentionally—that biases exist in the data itself. It was discovered that an AI software designed to identify patients in need of further medical attention was biased towards certain races. Although there existed racial bias in the underlying data used to develop and train the AI programme, the programme itself did not take race into account.

Responsibility
In the event that an AI decision causes harm or human injury, who is responsible? In the context of self-driving cars, this issue is extremely serious. Who is at fault in an accident involving a car that is being driven in the hands-off mode—the driver, the manufacturer, or the software designer?

Openness
A lender may respond with something like "the computer said so" if an AI programme rejects a loan application and the applicant asks why. It can be challenging to determine why an algorithm reaches a specific conclusion.

Investment - ​Financial Planning Services 
Advice on setting financial goals and figuring out how much to save is typically needed by investment customers. A few clients may require guidance regarding the amount of money they can allocate to expenses without sacrificing their capital. Financial planners assist their clients in understanding the dangers associated with investing, their tolerance for risk, and their preferences for wealth preservation over capital development. They also assist clients in understanding their current and future financial needs. 

Plans for investments and savings are made by financial advisors for their customers. The plans frequently need for a thorough examination of numerous moving parts: 

The anticipated risk and return rates for different assets and securities

The client's ability and willingness to accept risk 

Tax implications

Estimates of expenses


Expenses are frequently especially hard to predict. They could be influenced by inflation, healthcare expenditures, and, in the case of retirement, an erratic life expectancy. Actuaries are specialists in evaluating insurance risks using statistical models, and they generally analyze pension plans and healthcare data.  

Financial planners are employed by numerous pension plans to assist their beneficiaries in making more informed savings choices. Certain employers have agreements with financial advisors to provide their services to their staff members. Financial advisors are increasingly giving regular investors advice online. 

Financial planning may be necessary for organizations to achieve their investment goals.

For instance, non-profit organizations with long-term investment goals like foundations and endowment funds employ financial planners to develop payment plans. The amount that can be withdrawn out of long-term savings for immediate use in expenditures is determined by payout policies.

The financial planners' assumptions regarding the returns on investments determine the payout policies. Higher spending is permitted if future returns are assumed to be high; however, if these assumptions are overly optimistic, payouts will exceed returns, necessitating a reduction in expenditure in order to protect the fund's capital.

Investment - How the Investment Sector Encourages Profitable Investing 
Individuals and institutional investors with capital to invest are served by the investing sector. As capital providers, the majority of investors go to professionals for help with tasks that they are unable to perform on their own or may decide not to perform, such as the following:

Establish your financial objectives and the amount of money required to achieve them.

Determine possible financial investments.

Analyze the potential investments' risk and return.
Trade assets and securities

Hold, oversee, and record assets and securities during the investment periods.

Analyze the investments' performance.

Typically, these actions call for infrastructure, knowledge, and information that few institutional or individual investors have. 

Investment experts help investors with these phases; they can be hired, or they can invest in investment vehicles that the industry develops and manages.

While some investing specialists offer only one service, others offer a wide range.

​Investment - The Life of A Trade 
Transaction 
An investor gave the broker a sell order. 
A broker paired a buy order and a sell order. 
The broker has the option to match an internal buy order with the sell order. An exchange may get a small order for automatic matching. To automatically match minor deals with the best buyer offer, for instance, highly liquid stocks are usually submitted to an exchange (like the New York Stock Exchange). The price of illiquid securities can be impacted by large trades. For instance, it could be necessary to divide up large orders into smaller ones and trade them gradually. 

Clearing and Settlements. 
Final confirmation of trade terms is followed by a final cash and securities exchange. Time+2 trade settlement is carried out by the clearing house or depository that offers additional services, such as Depository Trust Corp. in the US and Euroclear in Europe, on the second day after the trade. 

Custody and Services 
Custodians provide as a point of contact for asset owners and their investments, handling record-keeping, dividend distribution, and securities safeguarding. Brokers and custodian banks may offer custody services. Mellon Banks and Charles Schwab are two US examples of custodians.

Investment - ​Investment Information Services 
Investment research providers, credit rating agencies, financial news services, financial data vendors, and investment consultants are the sources of the financial data, investment advice, and investment research that investors want. These companies' business models are covered in this section along with an introduction.

Providers of Investment Research
Research studies that go deeper into the potential risks and returns of investments are used by many investors. Businesses that offer research reports compile data and insights that are difficult for most investors to generate on their own. These companies use professional analysts, financial reporters, and data collectors to create the reports.

When research is written by professionals in the field who comprehend the financial ramifications of emerging technologies or industry regulations, such as the regulatory pathway a biotech company must take to get approval for a new drug and the ensuing implications for the drug's release date, it can be especially valuable.

Data Input for Investment Research
Research reports, which save investors a great deal of time, are primarily based on publicly available data and summarize the words and numbers from lengthy disclosures, like financial statements and regulatory filings. The fundamental worth of securities is estimated in a lot of papers.

Brokers frequently provide research reports to investors; these firms either buy the papers or generate them internally through research divisions. Brokers disseminate studies to benefit their customers, draw in new ones, and motivate existing ones to trade. Additionally, investors have the option to acquire studies from independent research firms or from research organizations that were compensated by the corporations they worked with to develop the reports.


 Credit  Rating Agencies 
Opinions regarding the credit quality of bonds and the firms or governments that issue them are the specialty of credit rating agencies. A high bond credit rating means that the rating agency thinks there is a good chance the bond issuer will make all of the principal and interest payments on time in the future.

Although they might charge investors for the comprehensive studies that serve as the basis for the ratings, the majority of credit rating organizations do not charge investors for their ratings. Alternatively, businesses pay rating firms to assign a grade to their securities. They act in this way because a security that has a rating is usually more marketable.

Consequently, there is a clear conflict of interest since businesses will probably choose to do business with credit rating organizations that offer higher ratings. In a similar vein, corporations may receive good ratings from credit rating organizations in order to win future business. However, credit rating organizations face the risk of losing market respect if they lose their independence. Due to the decrease in capital flows, such a scenario would be detrimental not just to credit rating agencies but also to the overall economy and the investment sector in particular.

Data  Vendors 
Most investors want up-to-date, correct information about firms and market conditions in order to trade and invest profitably. Such data, including real-time and historical data, are offered by numerous data vendors. 

The historical data examples and potential applications for investors' usage in decision-making are provided in the flashcards below.

Examples of Historical Data and Its Possible Applications 

Macroeconomic  Data 
Macroeconomic data is used by investment professionals to have a deeper understanding of the business and competitive landscape.

An example of data regarding global trade and economic activities.

Corporate Accounting  Data
Corporate accounting data is used by investment professionals to evaluate the financial performance of a company and to determine the intrinsic worth of its instruments, such as common shares.

The balance sheet, income statement, and cash flow statement of a firm are examples of financial statement information.

Historical Market Data 
Investment experts assess the performance of existing holdings and pinpoint assets that could outperform in the future using historical market data.

For instance, past market prices and trading volume data.

Investment professionals use newsfeeds and market data feeds as crucial real-time data sources. Investors should be aware of the news that newsfeeds provide about markets and companies, as it has the potential to impact the value of the firms' securities. For investors who wish to trade, market data feeds offer useful information on market quotes, investor orders for securities, and the prices and volumes of previous deals.

Investment firms and institutional investors used to be the only ones with access to investment data because it was so expensive. The public now has more access to investment data thanks to the significant decrease in data access costs brought about by the development of information technologies, especially those that include the internet. Certain data can be readily viewed online in many countries, such as regulatory disclosures made by issuers. Additional data are only provided by data vendors via subscription.  

Although access to data was formerly a major factor in determining investment profits, the availability of investment data has significantly altered the landscape of the investment sector. Increasingly, investment profits now depend on the capacity to analyze data.
