Search for “AI investing” online, and you’ll be flooded with endless offers to let artificial intelligence manage your money.
I recently spent half an hour finding out what so-called AI “trading bots” could apparently do with my investments.
Many prominently suggest that they can give me lucrative returns. Yet as every reputable financial firm warns – your capital may be at risk.
Or putting it more simply – you could lose your money – whether it is a human or a computer that is making stock market decisions on your behalf.
Yet such has been the hype about the ability of AI over the past few years, that almost one in three investors would be happy to let a trading bot make all the decisions for them, according to one 2023 survey in the US.
John Allan says investors should be more cautious about using AI. He is head of innovation and operations for the UK’s Investment Association, the trade body for UK investment managers.
“Investment is something that’s very serious, it affects people and their long-term life objectives,” he says. “So being swayed by the latest craze might not be sensible.
“I think at the very least, we need to wait until AI has proved itself over the very long term, before we can judge its effectiveness. And in the meantime, there will be a significant role for human investment professionals still to play.”
Given that AI-powered trading bots may end up putting some highly-trained but expensive human investment managers out of work you might expect Mr Allan to say this. But such AI trading is indeed new, and it does have issues and uncertainties.
Firstly, AI is not a crystal ball, it cannot see into the future any more than a human can. And if you look back over the past 25 years, there have been unforeseen events that have tripped up the stock markets, such as 9/11, the 2007-2008 credit crisis, and the coronavirus pandemic.
Secondly, AI systems are only as good as the initial data and software that is used to create them by human computer programmers. To explain this issue we need a little history lesson.
Investment banks have actually been using basic or “weak AI” to guide their market choices since the early 1980s. That basic AI could study financial data, learn from it, and make autonomous decisions that – hopefully – got ever more accurate. These weak AI systems did not predict 9/11, or even the credit crisis.
Fast-forward to today, and when we talk about AI we often mean something called “generative AI”. This is far more powerful AI, which can create something new and then learn from that.
When applied to investment, generative AI can absorb masses of data and makes its own decisions. But it can also work out better ways to study the data and develop its own computer code.
Yet if this AI was originally fed bad data by the human programmers, then its decisions may simply get worse and worse the more code it creates.
Elise Gourier, an associate professor in finance at the ESSEC Business School in Paris, is an expert in the study of AI going wrong. She cites Amazon’s recruitment efforts in 2018 as a prime example.
“Amazon was one of the first companies to get caught out,” she says. “What happened was that they developed this AI tool to recruit people.
“So, they’re getting thousands of CVs, and they thought we’re just going to automate the whole process. And basically, the AI tool was reading the CVs for them and telling them who to hire.
“The problem was that the AI tool was trained on its employees, and its employees are mainly men, and so, as a result of that, basically what the algorithm was doing was filtering out all the women.”
Amazon had to scrap the AI-powered recruitment.
Generative AI can also simply just go wrong, and produce incorrect information, something termed a “hallucination”, says Prof Sandra Wachter, a senior research fellow in AI at Oxford University.
“Generative AI is prone to bias and inaccuracies, it can spit out wrong information or completely fabricate facts. Without vigorous oversights it is hard to spot these flaws and hallucinations.”
Prof Sandra Wachter also warns that automated AI systems can be at risk of data leakage or something called “model inversion attacks”. The latter – in simple terms – is when hackers ask the AI a series of specific questions in the hope that it reveals its underling coding and data.
There is also the chance that AI will become less of a genius investment advice engine, and more like the stock pickers you used to find in the Sunday newspapers. They would always recommend some minor share to buy first thing on Monday morning, and miraculously the shares would always jump in value first thing that day.
This, of course, had nothing to do tens of thousands of readers all rushing to buy the share in question.
So despite all these risks, why are a sizeable number of investors seemingly keen to let AI make decisions for them? Business psychologist Stuart Duff, of consultancy firm Pearn Kandola, says some people simply trust computers more than other humans.
“It’s almost certainly reflecting an unconscious judgement that human investors are fallible, while machines are objective, logical and measured decision makers,” he says. “They may believe that AI will never have an off day, will never deliberately cheat the system, or try to hide losses.
“Yet an AI investment tool may simply reflect all of the thinking errors and poor judgements of its developers. More than that, it may lose the benefit of intuitive experience and rapid reaction when unprecedented events strike in the future, such as the financial crash, and the Covid pandemic. Very few humans could create AI algorithms to cope with those massive events.”

Have you ever considered creating an ebook or guest authoring on other blogs? I have a blog centered on the same topics you discuss and would really like to have you share some stories/information. I know my readers would value your work. If you’re even remotely interested, feel free to send me an e mail.
I truly appreciate this post. I have been looking everywhere for this! Thank goodness I found it on Bing. You have made my day! Thanks again
Nice blog! Is your theme custom made or did you download it from somewhere? A theme like yours with a few simple tweeks would really make my blog shine. Please let me know where you got your theme. Appreciate it
I am constantly searching online for articles that can help me. Thx!
Thank you for sharing with us, I think this website really stands out : D.
I conceive other website owners should take this web site as an example , very clean and wonderful user genial layout.
you are really a good webmaster. The site loading speed is amazing. It seems that you are doing any unique trick. Moreover, The contents are masterwork. you have done a excellent job on this topic!

Hmm is anyone else having problems with the images on this blog loading? I’m trying to find out if its a problem on my end or if it’s the blog. Any feedback would be greatly appreciated.
There are definitely quite a lot of particulars like that to take into consideration. That is a nice level to bring up. I provide the ideas above as basic inspiration but clearly there are questions just like the one you convey up where crucial thing might be working in honest good faith. I don?t know if finest practices have emerged around things like that, however I am certain that your job is clearly identified as a fair game.

very good publish, i actually love this web site, keep on it
You actually make it seem so easy with your presentation but I find this matter to be really something that I think I would never understand. It seems too complex and extremely broad for me. I’m looking forward for your next post, I’ll try to get the hang of it!
A person essentially help to make seriously posts I would state. This is the first time I frequented your website page and thus far? I surprised with the research you made to make this particular publish incredible. Magnificent job!
I was curious if you ever considered changing the layout of your website? Its very well written; I love what youve got to say. But maybe you could a little more in the way of content so people could connect with it better. Youve got an awful lot of text for only having 1 or two images. Maybe you could space it out better?
I always was concerned in this topic and still am, thankyou for posting.
