Wallstreetlocal – View investments from America's biggest companies
Hello Hacker News! My name is Anonyo, and I am a seventeen-year-old from Southeast Michigan. This is wallstreetlocal, my passion project for the last year (and a half). I've posted this before, but I've finally open-sourced this entire project, so I thought I'd post it again. Heres the short pitch. The Securities and Exchange Commission (SEC) keeps record of every company in the United States. Companies whose holdings surpass $100 million though, are required to file a special type of form: the 13F form. This form, filed quarterly, discloses the filer's holdings, providing transparency into…
Wallstreetlocal – View investments from America's biggest companies launched on March 8, 2024 with 299 votes, #123 of 4,270 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 2 years on.
In plain words
Wallstreetlocal makes SEC 13F filings more accessible to the public. The tool aggregates quarterly investment holdings data from major U.S. companies required to disclose their portfolios, which is normally difficult to access and often paywalled. Users can view and analyze investment activities from America's largest companies in one place. The project is open-source and available on GitHub.

Hello Hacker News! My name is Anonyo, and I am a seventeen-year-old from Southeast Michigan. This is wallstreetlocal, my passion project for the last year. The United States Securities and Exchange Commission (SEC), forces institutional money managers whose portfolios surpass $100 million to quarterly update the SEC website with their latest investments. These money managers, known as 13F (the form type of the report) filers, are the biggest investors in America, and the law forces them to publicly reveal their investments. The problem I found was that SEC filings are cumbersome to find and…
Wealthfolio: Private, open-source investment tracker2024 · wealthfolio.app · ▲924Thank you for your comments, just some context: - The app is a simple desktop application that works on macOS, Windows, and Ubuntu. - I developed this app for my own needs. Getting tired of SaaS app subscriptions and privacy concerns. - For now, the activities are logged manually or imported from a CSV file. No integration with Plaid or other platforms. - No monetization is planned for now (only a "buy me a coffee" if you use and appreciate the app).

(* within a few minutes of SEC filing) Currently does it for 1000+ US companies and specifically earnings related filings. By US companies, I mean the ones that are obliged to file SEC filings. This was the result of almost a year long effort and hundreds of prototypes :) It currently auto-publishes for 1000 ish US companies by market cap, relies on 8-K filing as a trigger. e.g. https://www.signalbloom.ai/news/NVDA will take you to NVDA earnings Would be grateful to get some feedback. Especially if you follow a company, check its reports out. Thank you! Some examples:…
