Adamas Research is an investment research workspace: your portfolio, your watchlist and the research behind them, with the arithmetic kept honest.

Join the waiting listPrivate beta, by invitation.

For investors who do their own research.

  • You manage your own money

    Positions at more than one broker, in more than one currency, and a spreadsheet that has stopped keeping up. One ledger values all of it in your currency.

  • You read before you buy

    You want the filings, the company's own valuation history and the macro backdrop in one place, so a thesis can be checked against something.

  • You want the arithmetic right

    Returns that separate a deposit from performance, income from what was declared, and taxes matched lot by lot instead of averaged.

Not for trade signals, price targets or placing orders. Adamas never holds your money, never connects to your brokerage account and never tells you to buy or sell. You enter or import what you own; the decisions stay yours.

Every buy, sell and dividend goes into one dated book, valued in your currency at the ECB's reference rate of its own day, so money you added never reads as performance.

  • A money-weighted return over your dated cash flows, beside a time-weighted curve against the S&P 500 given the same deposits on the same days.
  • Dividend income from what each company last declared, labelled as such; an estimate only where nothing is on record.
  • Realised gains by tax year, matched first-in first-out, with fees in the basis and every currency kept apart.

One ledger, every currency

“Is 24 times earnings expensive?” has no answer alone and a clear one against the range this business has traded at. Each stock page puts today's multiple there, then asks what the price assumes.

  • P/E, price to sales and price to free cash flow over ten fiscal years from the SEC filings, ranked around the median.
  • A reverse DCF: the free-cash-flow growth today's price implies, set beside what the business delivered.
  • Ten years and twelve quarters of statements from XBRL, insider forms, 13F holders, FINRA short volume and fails-to-deliver.

A price, against its own history

Screen listed companies on size, valuation, yield, margins, leverage and momentum; keep the ones worth a second look on a watchlist with a buy target; be told when something moves.

  • Alerts on your price levels, large daily moves, upcoming earnings, dividend raises and cuts, unusual volume and economic releases such as inflation and jobs.
  • World indices at their real level, rates, the yield curve, currencies and commodity futures in their own units.
  • A weekly email: how your portfolio did, what reached its target and who reports next.

Find it, watch it, be told

Ask for a structured report on a company or a review of your portfolio and it is drafted from the figures already in the app, quoting the ones it relies on. It describes trade-offs; it never tells you to buy or sell.

  • Company reports, portfolio reviews, strategy outlines, market events, research ideas and scenario simulations.
  • A daily allowance per plan: 3 on Free, 25 on Core, 100 on Pro. A request that fails before it reaches the model is not counted.
  • Drafted by a large language model from Anthropic. It can be wrong with confidence; treat it as a start, then check the filings.

A second reader, not an oracle

Type a price. Read what it assumes.

Today's price implies free cash flow growing 11.1% a year for ten years. The business delivered 7.1% over the last five.

First, join the list. Leave your email. Accounts are opened by hand while the beta is finished.

Then, bring what you own. Import your broker's CSV or add holdings by hand. ISINs are matched to tickers and every guess waits for you.

Every night, the refresh. Prices, fundamentals, dividends and statements are refreshed, your portfolio is valued and the day's alerts checked.

Every Monday, your week, in one email. How the portfolio did, what reached its target and who reports next.

How the numbers are kept honest.

  1. No number beats a wrong number

    A loss-making year has no P/E rather than a negative one. A holding with no exchange rate is left out of a total, not added at face value. A provider outage is retried, never stored as “no data”.

  2. Medians, ranks and stated assumptions

    Valuation history uses the median, so one freak year cannot set the average. The reverse DCF prints its discount rate and shows the answer at 8, 9 and 10%.

  3. Primary sources first

    Statements come from the companies' own XBRL filings at the SEC; macro series from FRED; exchange rates from the ECB's reference fixing.

  4. Metrics that explain themselves

    Tap a key metric to see how it is worked out and, more usefully, what it does not tell you.

Data comes from Finnhub, Yahoo Finance, Twelve Data, CoinGecko, the SEC, FINRA, FRED and the European Central Bank reference rates via Frankfurter. Quotes can be delayed and fundamentals are refreshed on a schedule. Your account data is stored in the EU, and there are no analytics or advertising trackers.

Start free. Pay for the depth when you use it.

Prices in euros, with no VAT added (exempt under article 53 of the Portuguese VAT Code). A plan is chosen from inside your account and renews until you cancel it; the terms set out cancelling and the 14-day right of withdrawal.

The terminal, the valuation models, the trading journal, the money and property ledgers are the operator's own tools and not in any plan yet.
