How technology changed investing and trading

[Disclaimer: This article is intended for US audiences]

Investing used to move a lot more slowly. Access to markets was limited, trades required human intermediaries, and information travelled through newspapers, television or scheduled reports. Participation often depended on who you knew or which financial institutions you could reach. For many individuals, investing felt distant, complex and reserved for professionals.

Technology has changed that. Digital platforms, mobile apps and data infrastructure have reshaped how people research, execute and monitor trades. What was once procedural has become immediate. What once required a phone call to a broker can now be completed in seconds on a smartphone.

It isn’t just about convenience. It shows a bigger change in access, behaviour, risk perception and the function of financial intermediaries. Understanding these changes can help you to not only understand the industry more but also use these advancements to your advantage.

The older model of market access

Before widespread internet adoption, retail investors interacted with markets through more formal channels. A typical process involved contacting a broker, discussing an order and waiting for execution. Delays were normal, pricing information was not always real-time and research tools were largely institutional.

This structure created several natural constraints:

While this model limited speed and accessibility, it also imposed pacing. Investors had fewer stimuli and fewer opportunities to react instantly to market noise.

Digital platforms and the removal of friction

Online trading platforms changed the mechanics of participation. Execution speed increased, interfaces simplified order placement, and data feeds became continuous. Mobile technology further reduced barriers, allowing market access from virtually anywhere.

Several developments stand out:

These changes did not eliminate the broker, but they changed expectations. Instead of being the sole channel to the market, the broker increasingly became one option within a larger digital ecosystem.

How investor behaviour has changed

When trading becomes faster and more accessible, investor behaviour rarely stays the same.

These shifts subtly alter the relationship between investors and expertise, as a broker may still offer guidance but no longer controls the primary flow of information.

Persistent misunderstandings about technology and markets

Despite technological progress, some assumptions about modern investing deserve closer scrutiny.

These misunderstandings are not unique to retail investors. Rapid technological adoption often creates optimism about accuracy and control, even in probabilistic environments like financial markets.

The evolving role of the broker

Technology has not made brokers obsolete, but it has changed their function. Instead of acting primarily as transaction facilitators, brokers increasingly operate as service providers within digital infrastructures.

Their relevance now often centres on areas such as:

At the same time, digital brokerage models have emerged, blending automation with varying levels of human support. The distinction between platform and broker is less rigid than before. This evolution reflects a broader pattern seen across industries. Technology reduces mechanical tasks while increasing demand for contextual judgement and specialised expertise.

Why these changes matter beyond convenience

The transformation of investing mechanics carries wider implications. Faster execution and constant information flows can amplify volatility in behaviour. Reduced friction can encourage experimentation, but also increase exposure to poorly understood risks.

Market participation has broadened, yet the cognitive demands on investors have also expanded. Individuals must process more information, make quicker decisions, and manage psychological pressures associated with continuous monitoring.

Technology, therefore, acts as both an enabler and a stressor. It expands opportunity while altering the environment in which choices are made.

A continuing transition rather than a completed shift

It is tempting to view digital investing as a finished transition, but the landscape continues to evolve. Artificial intelligence tools, predictive analytics, and interface design will likely further reshape how investors interact with markets.

What remains consistent is the underlying challenge. Markets still require interpretation, discipline, and risk awareness. Technology changes the tools and tempo, but not the fundamental uncertainties.
