Happy to elaborate on how ARC OS works — It parses subjective input into logic trees with assumptions, conflict checks, bias flags, and reasoning trails. It’s symbolic only (no LLMs), designed for alignment auditing, law/policy frameworks, and decision explainability. If anyone wants an example, I can post a breakdown here.

I think others are asking more about the real-world investment value of this, not the technical implementation. What actual trades were made by the user/creator? What was the ROI? How did profitability compare to their returns before using this tool? With today's LLM's it's easy for anyone to generate a 20-page "report" with a analysis about investments. But a report that, when followed, actually gives you above-aver…

Sorry, I think I replied in the wrong thread. My comment was meant for a different topic — feel free to ignore!

Well the most important information is missing: what was your ROI ? :D

I'm going to assume this project is at best a few years old, so return over index is more likely to be an indicator of overbetting (taking on too much risk) than a performance indicator. Backtesting would be more useful. Of course, LLMs cannot be backtested since they know the past. This system is impossible to test. I would be hesitant to trust it.

it looks like the code was committed a week ago. I do not see an iterative history on the code

The ideal design for such an agent is that it would tell you to put all your money in a Betterment account, and then if you try to do anything other than that it should give you electric shocks until you stop. (Vanguard if you don't benefit from tax loss harvesting.)

Is that going to beat FXAIX in a Fidelity account? The expense ratio is 0.015% and it tracks the S&P 500.

If you're fine with 100% risk then probably not, but you want some low-risk assets depending on your age. And if you have high marginal tax rates like anyone living in CA does then a little tax optimization is worth it.

Is it possible to try your real estate AI agent? I've built a real estate data API (stream.estate) and would be very much interested to see how it works; maybe we can add some features to make that kind of project better.

Oh, also mutual funds like FXAIX are less tax-efficient than ETFs.

I didn’t build this to beat the market...it started as a way to reduce my own decision fatigue and make sure I wasn’t missing obvious signals. That said, it’s more of a research agent than a trading bot. For ROI, it’s not auto-trading, but it has helped me avoid a few bad calls and made my reports more consistent and thorough.

Hate to be that guy but I'm not sure how this is any better or more reliable than something like FinViz or NeighborhoodScout.

Great question and those are solid tools! Where this differs is the orchestration. Instead of switching tabs or manually checking five sources, this bundles everything into one interactive, LLM-assisted report, plus it remembers your preferences, investment style, and context. You can even swap out GPT for a local model if you’re privacy-conscious or budget-sensitive.
