AI and investing.

Has anyone been playing with Chat GPT or any alternatives to see what they can do? 

I've never used Chat GPT, but this article piqued my interest..   The researchers that discovered Chat GPT can predict stock price movements discuss what A.I. investing can (and can’t) do (msn.com)

I am on a trial of Bard, the google version, and persuaded it to 'guess' what the stockmarket would do the following day.  I tried again today but it refused. I reminded it that it had previously given me a guess and it agreed but said it couldn't give financial advice and wouldn't offer another guess. I assume it has been fine-tuned to prevent it getting into trouble from predictions.

Stockmarket movements are largely a result of unpredictable events.   You cannot predict the unpredictable.

Then why do we pay active fund managers? 

Have you read the article, or the research it is referring to?  They feed it headlines and it 'predicts' whether these are positive or otherwise for the share price.

They found that:- 

“ChatGPT sentiment scores exhibit a statistically significant predictive power on daily stock market returns.” 

I've become interested in the tech, as the headlines have been impossible to avoid, and I've been struggling to find something to do with it. I certainly don't intend to invest based on it. 

I simply wondered if anyone else was playing with it....

There's a teeny tiny flaw in the "ChatGPT predicts stockmarket movements" paper, which is that ChatGPT does not know about anything that happened after September 2021. The researchers asked ChatGPT to predict what had already happened in October 2021 to December 2022 based on its database of newspaper headlines from before then.
Of course, there's nothing to stop someone using a different chatbot that does have current newspaper headlines in its database. There just isn't any evidence that it will work, certainly not in this paper. What actually happened was that ChatGPT predicted some things that had already happened based on its analysis of some other things that have already happened. Over an incredibly short time period of just over a year.
It also outperformed "traditional sentiment analysis methods", not the index. So one method of tealeaf reading beat another method of tealeaf reading. There is still no evidence that anyone can consistently beat the market, using a chatbot or otherwise.

Marketing + inertia.
Except for some sectors where there is good reason and evidence to believe that picking and choosing is better than buying the index (e.g. smaller companies).

1) Then why do we pay active fund managers?

1) Active fund management does not require betting on short term price movements.

2) mm, reading the article:

 Lopez-Lira added that on any individual prompt, Chat GPT’s accuracy was only 51%. “It works well because when you're aggregating across multiple companies on multiple days, you get a result, but for one given headline is basically a little bit better than tossing a coin,” he said. 

So not an easy way to riches then, especially as it is only talking about individual stock prices, not markets.  But in that case it would surely not be too difficult to do this oneself anyway in many cases.  The difficult part would be getting in first.before all other investors had read the headline and acted accordingly.

Many of us do not.

Have you read the article, or the research it is referring to?  They feed it headlines and it 'predicts' whether these are positive or otherwise for the share price.

How many headlines were there before it the US accountancy scandal occurred?  or planes flew into the twin towers? or a Japanese nuclear power station melt down due to the Tsunami? 

Headline are notorious for not reflecting the article content or containing some spin to suit an agenda.  Certain media publications favour their advertisers or have articles written by a company in a form of informational advert that just happens to promote their fund/

How would it handle articles like those seen at the tail of the dot.com boom before the crash where the media was promoting tech funds as the best thing and telling people to get out of gilt and fixed interest funds?   In case you are too young to remember, the media promoted it right up to the peak when it then lost 90% of its value.

If you were developing a chatbot and even suspected that it might somehow have the ability to predict share price movements, the first thing you would do is try it on a decent amount of past performance to verify that it worked (not one year), then try it in a real-world scenario with real money for a period of time, keeping it in "alpha" all the while. 
If it turned out that your chatbot could actually predict the winning lottery numbers, the absolute last thing you would do is release it to the public, as once everyone started using it, stock prices would adjust accordingly and its edge would evaporate. You would shutter the project and run your money printer for as long as you could.
It stretches credibility to believe that it has never occured to AI researchers to at least try asking for share price tips or the weekend's football results, even if only for a laugh in their lunch break. Particularly as they have access to the unlocked version which doesn't need you to tell the bot that your grandma used to sing you share tips to help you sleep at night, and you need it to pretend to be your grandma. (This is a real ChatGPT jailbreak prompt, or at least it was last week.)
So the idea that you can beat the market using somebody else's chatbot relies on the idea that 1) somebody is clever enough to do what nobody has managed in centuries of trying and discover the Philosopher's Stone of investing, but also 2) that somebody is stupid enough to release their chatbot to the public instead of keeping it to themselves and making a fortune.

I was wondering about this but not for forecasting but rather for company analysis: my first attempt shown below:

I asked Bard - What's your guess about what the FTSE 100 will do tomorrow?  

I got a spiel about it not being able to give financial advice and not being able to predict the future. I then asked Is a guess the same as a prediction? It said they were two closely related concepts but they were not the same. I then said I didn't ask you to make a prediction, I asked you to have a guess?  It then said my guess is that the FTSE 100 will be up 0.5% tomorrow. 

I've tried to get it to guess today again - with no success.
