Large language models like ChatGPT and Gemini might change the world, but they still have room to grow as financial advisors.
The models tend to consume all the available financial knowledge (from BlackRock annual reports to WallStreetBets on Reddit) and then produce something that initially sounds plausible but often lacks context. It’s the classic firehose approach.
Despite the hiccups, it’s worth taking a closer look at what’s going on with investing and chatbots.
Starting this week, we’re going to ask ChatGPT for one stock pick every week and see just how well the chatbot fares. We’ve included the exact prompt and methodology below so you can try it for yourself.
This should not be considered financial advice and is purely for entertainment and educational purposes.
ChatGPT stock pick of the week: Micron Technology (MU)
Here’s what ChatGPT has to say:
Micron Technology (MU) is a compelling buy this week, with AI-driven demand for HBM and DRAM, rising pricing, and improving inventories positioned to power strong revenue and earnings growth into 2026. Multiple analyst lists this week highlight MU among top near-term ideas in semiconductors as AI infrastructure spending accelerates beyond the GPU layer.

Our take
Micron is one of our favorite stocks, which we have written extensively about over the past few years. In July 2024, we published the article, This AI Stock Could Explode in 2024– And It’s Not Nvidia, about Micron. Dave Kovaleski wrote at the time: “Micron now stands out as a better option than NVIDIA stock, at least in the short term.” Since that article was published, Micron has outperformed Nvidia.
Also, in September 2024, we called Micron the best tech stock to buy. In addition, Micron made our list of the top 10 AI stocks. More recently, in both June and September of 2025, we called Micron a “favorite,” a “great value,” and a “rare bird in the investing world” as an undervalued AI stock. We also reiterated our call that Micron is an excellent option for investors for its low valuation and strong growth potential. The stock is up 128% YTD and 84% over the past 12 months with a still low P/E ratio.
Other AI stocks picks this week
Gemini took a very different direction, focusing more on the parameters themselves and less on in-depth research. Here’s the reasoning that Gemini provided:
Gemini Weekly Pick: Bristol-Myers Squibb (BMY)
To start your diversified, medium-risk portfolio, your first $100 weekly value stock recommendation is Bristol-Myers Squibb (BMY), a large-cap pharmaceutical company with a wide economic “moat.” It currently appears significantly undervalued according to value investing metrics and also offers a solid dividend yield.
How did last week’s pick perform?
Check back next week! This is our first article in the AI Insight series so it will be interesting to see how this plays out in the coming months.
Methodology
Every week we will ask ChatGPT for a stock recommendation after trading has closed on Wednesday.
We created a stock investing space on Perplexity Pro using the GPT-5 model. Here’s the exact guidelines that were provided to the model:
I’m a 30-year-old investor with medium risk tolerance. I’m planning on buying $100 of a different stock every week. I’d like you to give me recommendations as best you can. I want you to look for the single best value stock every week. Don’t repeat stocks as I’d like to build a diverse portfolio.
We’ll continue to provide long-term updates on the performance of the overall portfolio.
Disclaimer: Neither the large language models or ValueWalk suggest actually using this as an investment strategy. This article is for educational purposes only.
