There is a growing belief that artificial intelligence will eventually take on a bigger role in investment decisions.
The logic is simple. More data, faster analysis, better outcomes.
But that logic breaks down quickly when tested in practice.
Recent evaluations of widely used AI systems show that while they can process information quickly, they struggle with consistency. Errors are not rare. They are frequent enough to raise real concerns, particularly in areas that require precision and context.
The problem is not intelligence. It is reliability.
AI can generate answers that sound convincing, even when they are wrong. In a low-stakes environment, that is manageable. In portfolio construction, it is not.
Investment decisions rarely come down to clean inputs and clear outputs. They involve judgement, interpretation, and an understanding of factors that are not always visible in the data. Markets move on sentiment, expectation, and events that cannot always be modelled in advance.
That is where AI starts to fall short.
It can assist with the process. It can summarise research, identify patterns, and reduce the time it takes to analyse information. But it cannot replace the decision itself.
For advisors, that line is becoming clearer.
AI is being used more frequently, but within defined boundaries. Outputs are reviewed, assumptions are questioned, and human oversight remains central. The technology is treated as a tool, not a substitute.
There is also a regulatory reality that reinforces this.
Fiduciary responsibility does not change because a model is involved. Advisors are still accountable for the outcomes. That makes blind reliance on AI not just risky, but unacceptable.
Over time, the technology will improve. More specialised models will emerge, built specifically for financial use cases. Accuracy will increase. Reliability will follow.
But that is not where things stand today.
For now, AI can make the process faster. It can make research more efficient. It can support better preparation.
What it cannot do is take responsibility.
And in this industry, that is the part that matters most.
