The Investment Evolution: Will Computers Take Over?

Computers have become an integral part of the finance industry, with many companies opting to employ tech talent to teach computers about finance. Computers have various advantages over humans when it comes to finance, including superior number-crunching and mathematical abilities. When combined with sophisticated algorithms, computers become a formidable force in the financial services industry. High-frequency trading firms, for instance, rely on computers to execute thousands of orders in nanoseconds, contributing to a significant reduction in trading costs. Additionally, the rise of robo-advisors and algorithmic fund management strategies has sparked a shift towards passive investing, further highlighting the growing influence of computers in the financial domain.

Computers are better at number crunching and mathematics

A supercomputer, for example, is a collection of thousands of smaller computers working in parallel. While a typical computer can perform about four billion mathematical operations per second, sequentially, a supercomputer can perform many more operations simultaneously by distributing small pieces of calculations to its constituent computers. This allows supercomputers to carry out trillions or even quadrillions of operations per second, resulting in a massive speed advantage.

In the financial industry, computers have enabled High-Frequency Trading (HFT) firms to execute thousands of orders in nanoseconds, leading to a significant reduction in the cost of trading. HFT currently accounts for over 70% of all equity trades in the US. Additionally, the use of robo-advisors in the financial industry has provided low-cost access to financial advice, with online robo-advisors capable of managing millions of dollars in a tax-effective way for a fraction of the cost of human advisors.

Computers also excel at processing and analysing vast amounts of data, enabling them to identify patterns and make informed decisions based on sophisticated algorithms. This capability is particularly valuable in the financial industry, where it can be leveraged to optimise investment strategies, minimise risks, and maximise returns.

While computers have proven their superiority in number crunching and mathematics, it is important to acknowledge that human expertise and oversight are still crucial. Computers rely on algorithms and data fed to them, and their effectiveness depends on the quality and accuracy of the input they receive. Ethical considerations and long-term strategic planning are also areas where human input remains essential.

Computers are the biggest force in the delivery of financial services

Computers have become the biggest force in the delivery of financial services. They have revolutionized the way transactions are conducted, investments are managed, and risks are assessed.

One of the most significant impacts of computers in finance is the rise of online banking and digital payments. Computers enable consumers to access their accounts, transfer funds, pay bills, and manage investments from anywhere in the world, at any time. This convenience has transformed the way people interact with their money, making it easier than ever to conduct financial transactions and monitor their financial health.

Computers also play a crucial role in electronic trading and financial markets. High-speed trading algorithms powered by computers execute millions of trades per second, enabling investors to buy and sell securities quickly and efficiently. These algorithms help optimize trading strategies, minimize transaction costs, and provide liquidity to financial markets, contributing to market efficiency and stability.

Additionally, computers are indispensable in risk management. Advanced risk modeling techniques powered by computers help financial institutions assess and manage a wide range of risks, including credit, market, and operational risk. By analyzing vast amounts of data and simulating various scenarios, risk management systems enable institutions to make informed decisions and mitigate potential losses.

The integration of computers into financial processes has also led to improved fraud detection. Machine learning algorithms analyze transaction data in real time, flagging suspicious activity and identifying potential instances of fraud. These algorithms help protect customers' assets and maintain the integrity of the financial system, ensuring trust and confidence in the banking system.

The use of computers in financial services offers many benefits, but it also comes with challenges. Cybersecurity threats, data privacy concerns, and algorithmic bias are some of the issues that financial institutions need to proactively address. Implementing robust security measures, ensuring compliance with data protection regulations, and promoting transparency and accountability in algorithmic decision-making are essential to mitigate these challenges.

Furthermore, the development of quantum computing has the potential to revolutionize financial services even further. Quantum computers can process vast amounts of data at superfast speeds, enabling financial institutions to analyze large or unstructured data sets more effectively. This can lead to better decision-making and improved customer service. While fully scaled quantum technology is still in the future, financial institutions are already exploring its potential advantages.

Robo-advisors offer low-cost access to financial advice

Robo-advisors are a low-cost alternative to traditional financial advisors. By eliminating human labour, online platforms can offer the same services at a fraction of the cost.

Robo-advisors use algorithms to automate and optimise passive indexing strategies based on modern portfolio theory. They are often inexpensive and require low opening balances, making them available to retail investors.

The fees for robo-advisors vary, but they are generally much lower than those of traditional financial advisors. For example, most robo-advisors charge an annual flat fee of less than 0.4% per specific amount managed, while human financial planners typically charge 1% or more.

Robo-advisors also make it easier to keep track of investments. You can log in and check on your investments 24/7 as long as you have an internet connection.

Robo-advisors are best suited for traditional investing and may not be the best option for more complex issues such as estate planning. They have been criticised for their lack of empathy and complexity.

Algorithms allow for better price discovery for investors and institutions

In economics and finance, price discovery is the process of determining the price of an asset in the marketplace through the interactions of buyers and sellers. It is influenced by a wide variety of factors, including the number of buyers and sellers, market mechanism, available information, and risk management choices.

For example, investors who use direct investing and algorithms are no longer dependent on stockbrokers for buying and selling financial products. With this method, investors can get the best possible price for their stock purchases. Additionally, algorithms allow institutions to buy and sell large quantities of stock and other securities without affecting the price of the security. This process is also faster and cheaper, and institutions can be guaranteed a better price than with a manual trade.

The use of algorithms for price discovery has led to a reduction in the cost of owning financial assets. This has made investing more accessible, as financial assets that were once a luxury for the super-rich are now available to almost anyone with some income.

Furthermore, algorithms have contributed to the rise of High-Frequency Trading (HFT) firms, where computers execute thousands of orders in nanoseconds. HFT accounts for over 70% of all equity trades in the US and has led to a further reduction in the cost of trading.

Algorithms are replacing fund managers

The stock market has evolved from a distinctly human affair to one increasingly driven by computers, algorithms, and passive managers. This shift has sparked debates about the role of markets, corporate governance, and financial stability. While some celebrate the benefits of algorithmic trading, others question its long-term effectiveness and the potential disintermediation in the industry.

The Rise of Algorithmic Trading

The concept of computerized trading in financial markets is not new, with early attempts dating back to the 1970s. However, the recent advancements in technology and the rapid pace of change have propelled algorithmic trading to the forefront. This type of trading uses computers and programs to generate and execute large orders in the market, relying on predefined rules based on factors like price, timing, and quantity.

Advantages of Algorithmic Trading

Algorithmic trading offers several advantages over traditional methods:

• Speed and Efficiency: It enables faster trading and eliminates the need for manual intervention.
• Risk Management: It provides tools for data mining, exploration, and strategy testing, allowing investors to make more informed decisions.
• Cost Reduction: The use of algorithms has led to a decrease in the cost of owning financial assets, making investing more accessible to individuals with modest incomes.
• Improved Price Discovery: Algorithms help investors obtain the best possible price for their stock purchases and enable institutions to trade large quantities of stock without significantly affecting security prices.
• Eliminating Human Bias: Algorithms can exploit short-term arbitrage opportunities, follow rules-based investment strategies, and make decisions without the influence of human biases.

Algorithms Replacing Fund Managers

The world's largest fund manager, BlackRock, made headlines with its decision to replace fund managers with algorithmic-based strategies. Over the last decade, their algorithmic funds have outperformed 90% of all active managers. This success has fueled the debate about the potential replacement of humans with robots in the industry.

Impact on the Industry

The increasing reliance on algorithms is expected to have a significant impact on the financial sector. According to a report by Opimas, financial firms are projected to reduce their human workforce by about 10% by 2025, resulting in substantial job losses, particularly in the money management industry.

While the advantages of algorithmic trading are evident, there are still questions about the long-term effectiveness of fully automated investing strategies. The future of the industry may lie in a combination of human expertise and machine efficiency, with algorithms supporting fund managers in making more informed decisions. Nonetheless, the trend towards algorithmic trading is undeniable, and the role of computers in investments is only expected to grow.
