AutoHypothesis
Agents self-improve their stock portfolio strategy.
What it does
I built a framework where ai agents search for market inefficiencies and optimize risk-adjusted returns through an agentic loop: (1) propose a hypothesis with economic justification, (2) iterate on historical data (2010–2016), (3) validate on out-of-sample periods (2017–2021). No hyperparameter tuning is allowed once a strategy enters validation, forcing the system to behave like a researcher. Holdout results (2022–2025): Sharpe 0.86 vs. 0.67 benchmark, 28.1% turnover, 11.4% max drawdown.

Hey HN, I’m Dan. I’ve been working on forecasting for the last six years at Google, then Metaculus, and now at FutureSearch. For a long time, I thought prediction markets, “superforecasting”, and AI forecasting techniques had nothing to say about the stock market. Stock prices already reflect the collective wisdom of investors. The stock market is basically a prediction market already. Recently, though, AI forecasting has gotten competitive with human forecasters. And we’ve found a way of modeling long-term company outcomes that is amenable to our forecasting approach. Iteration by…

- TITrendFi – I built AI trading signals that self-optimize2025 · trend.fi · ▲35
Hey HN, For the past few years, I've been obsessed with trying to get AI to produce accurate trading signals. The main challenges I found with AI trading models are lack of consistency, context window bottlenecks, hard to backtest, and high cost. Asking ChatGPT "Should I buy Bitcoin today?" doesn't work well because the LLM doesnt have a set trading strategy to opperate from. In addition, the small context window makes it challenging to fit enough historical data into. Not to mention it gets very expensive as well. My solution is a hybrid approach. Instead of having the LLM make direct…

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
