Build a market-news agent for investing signals

A commenter is wiring up an agent to combine weekly market data with filings and news so they can spot sector shifts sooner.

What they did
They are putting together a custom agent on a VPS and plan to refresh its inputs by hand each week. Those inputs include reviews of top growth names and industry groups, along with a spreadsheet that sorts roughly 200 sub-industries by how they are doing versus the S&P 500. The agent also has access to SEC EDGAR and a lower-cost news API with a short delay, letting it tie odd changes in relative strength to the headlines from the week before.
How it went
They want to identify big industry moves within a few days and capture most of the run, using companies such as Intel, AMD, and Marvell as examples. They say they are only just beginning to use it in this agent-driven way, so there are no results to report yet.
Tips
You still need to supply the core research by hand every week. The main downsides they call out are the VPS setup and the ongoing API costs.
