About PWW

An independent US stock and ETF research workspace for self-directed investors.

Last updated: 2026-10-19

What PWW is

PWW is an independent research workspace for self-directed investors who follow US stocks and ETFs. It is designed to keep the securities you follow, the positions you record, and the evidence behind your decisions in one place.

The product is intentionally narrower than a brokerage or a market-wide data terminal. It helps you organize your own research process; it does not decide what you should buy or sell.

What you can do

  • Build watchlists and collections around the stocks and ETFs you want to follow.
  • Record holdings transactions and cash, then review saved portfolio snapshots.
  • Save research notes with the questions, review dates, and source evidence that matter to you.
  • Review available company facts, institutional disclosures, and ETF holdings data with their dates and coverage.
  • Compare supported ETFs and review their reported holdings overlap.

Where the data comes from

Market and company facts come from Financial Modeling Prep (FMP). Institutional holdings context comes from 13F.chat. Each view is intended to show the source and date that apply to the data being displayed.

Data can be delayed, incomplete, revised, or unavailable. Coverage differs by security and dataset. A missing value is not treated as zero, and a saved portfolio snapshot is not a live valuation.

How to read the data

Check the source date, reporting period, currency, and coverage before drawing a conclusion. Reported figures and calculated figures are different kinds of evidence. Where a value is unknown, PWW should say so rather than infer it.

What PWW does not do

  • It does not execute trades or hold assets.
  • It does not provide personalized investment advice.
  • It does not guarantee returns or the accuracy of third-party data.
  • It does not publish your private watchlists, holdings, or research notes.

AI-assisted research is being evaluated. It is not part of the current public offering, and paid subscriptions are not currently available.
