Human decision-making is almost extinct when it comes to the financial world, especially in trading and investing. This is because algorithms mostly run modern financial markets. From ticker tape machines to algorithmic trading, this revolution was swift. Technology fundamentally changed investing by making data more accessible, investment decisions much faster, and strategies smarter.

Let’s analyze how technology shaped and changed modern investment decisions through AI, big data, mobile platforms, and much more below in this compact explanation.

Investment Tech Evolution

The most famous of all investment and trading decisions was achieved through the use of Artificial Intelligence (AI). Many industries have embraced this technology, with Forex AI trading and crypto AI trading bots among the first to do so. This tech enabled retail investors to outsource their trading decisions to intelligent machine code that analyzes and learns market patterns. This is much more different than manual research, broker calls, and newspapers, which were the way of investing years back.

AI Investment Tech Evolution Blockchain Crypto DeFi

Modern technology enables you to get all the important news at the palm of your hand using smartphones and advanced apps, many of which are free. Online platforms offer real-time data, which is typically updated every second and even in milliseconds, depending on the investment and trading platforms.

What started with newspapers and desktop platforms continues using robo-advisors and algorithmic investment decisions.

Data as a Modern Currency

Modern investors can access and analyze big data to get insights that were previously only possible for large institutions. Prominent examples include predictive analytics, sentiment analysis from social media, and alternative data sources. Modern algorithms can analyze these data sources immediately and provide unparalleled insights into financial markets. They can even access social media to detect investor sentiment and hype. However, while these tools are super useful to gain wise insights into markets, the risk of data overloading is higher than ever.

Simply put, there is too much information and too many variables, which makes it difficult to differentiate which one is of higher quality information and which is just noise.

AI & Machine Learning

The latest and most potent technological advancements, which are revolutionizing the financial world, including investing and trading, are, of course, AI. These algorithms act like the human brain and can learn from patterns and then use this knowledge to react to real-world problems without the need to be preprogrammed. Unlike traditional trading systems, which are based on strict rules, AI-based robo-advisors can adapt to new market information and act on it.

AI offers faster execution, reduced human errors, and the ability to identify hidden opportunities that would be impossible for human investors to notice. Despite its many advantages, over-reliance on AI is not a good idea, and investors should always try to use human judgment as AI systems tend to produce incorrect predictions.

Mobile Platforms

Modern mobile apps are so advanced that they enable investors not only to access financial markets but also to employ various advanced tools to analyze price action. Apps like Robinhood, MetaTrader 5, Binance, and many more enable retail investors to quickly and conveniently access and trade markets.

These apps enable retail investors to start investing in financial markets with just a few dollars while simultaneously offering institutional-grade tools and analytics. Apps like Robinhood offer fractional shares and enable retail investors to buy stocks with a small amount of money and even access leveraged instruments.

Blockchain, Crypto, DeFi

Blockchain’s impact on the modern financial world is enormous. It was among the first financial sectors to adopt AI trading systems, and there are probably thousands of crypto AI bots released. However, where this technology truly shines is in security and decentralized finance. Crypto trading is alive and thriving, and thousands of retail traders access the market daily.

This asset class offers many trading opportunities. However, volatility is very high and presents many risks to inexperienced traders. Smart contracts enable new investment vehicles and decentralized trading. Staking and yield farming became popular as a result. As a result, investors nowadays have to also take into consideration Bitcoin and other digital currencies together with stocks to ensure a well-diversified portfolio.
