WHAT'S NEW

Your whole portfolio, kept current for you

Bring in every broker, follow the people worth listening to, and see what is really driving your returns.

BROKER SYNC · DEGIRO & IBKR

Two brokers, one ledger. No spreadsheets.

Connect Interactive Brokers once and Parra pulls your Flex Query every night. Drop in your DEGIRO exports, or let the browser extension upload them while you are logged in to DEGIRO.

  • IBKR: trades, dividends, withholding tax and positions, backfilled as far back as you choose
  • DEGIRO: Transactions, Account and Portfolio CSVs; the extension never sees your password
  • Every import is reconciled against the broker’s own holdings, and gaps are called out
  • A reminder when DEGIRO data falls behind, so the numbers never quietly go stale

VOICES · X ACCOUNTS

Follow the analysts on X. Skip the noise.

Add any X account by handle or profile link, or click “Track in Parra” on their profile with the Chrome extension. New posts are fetched and screened by AI; only investment-relevant ones make it to your feed.

  • Each kept post is tagged with the companies it discusses and a bullish or bearish stance
  • Every ticker links straight to the company, so a post leads to the research
  • Screened posts feed your thesis evaluations as one more source of evidence
  • A Voices tab on every stock page: the bullish and bearish count over 7, 30 or 90 days, and a dot on the price chart for each day someone posted
  • Off-topic posts are hidden, one click away if you want to see everything

PORTFOLIO · PERFORMANCE & RISK

Know why your portfolio moved

Performance measured against the money you actually put in, a P/L that adds up the way your broker’s does, and the concentration you might not have noticed.

  • Growth over any period, year by year and month by month
  • Total P/L split into unrealised, realised, dividends and costs, at trade-date FX rates
  • Concentration in your largest names, plus sector and currency exposure
  • Income tab: deposits, dividends net of tax, who paid you, and every fee

ANALYTICS · RISK & RESEARCH

The risks your broker never shows you

Parra maps the supply chains behind your holdings, measures your risk against a benchmark, and gives you a screener and a valuation panel to find and price the next idea.

  • Dependency radar: suppliers and customers several holdings share, with the weight exposed and a flag when you hold the counterparty too
  • Risk vs SPY: volatility, Sharpe, Sortino, max drawdown, beta, tracking error, and which holdings drive your variance
  • Screener: the S&P 500 plus the stocks you follow, ranked with presets like Quality Compounders, GARP and Dividend Growers, or your own rules
  • Valuation: a DCF, a reverse DCF that shows the growth the price implies, and peer multiples

HOW IT WORKS

Three habits of investors who sleep well

01 · WRITE THE THESIS

Every position gets a reason, and the evidence keeps score

Write down why you own each stock, set a target weight, and define measurable add and trim signals. Parra checks the news and the X posts you follow against those signals and sorts what it finds into Supports and Contradicts, with its confidence and reasoning for each. A balance bar shows which way the last 7, 30 or 90 days lean.

02 · LET THE AI ARGUE

Four AI analysts argue every stock you hold

A bull, a bear, an alpha-seeker and a capital-preservation analyst each make their case on the stock, then a synthesis reconciles them into one balanced recommendation with a confidence score.

03 · ASK ANYTHING

One box for search and answers — on every page

Hit ⌘K anywhere. Type a ticker to jump, or ask a real question. The assistant answers with the page you are on as context and cites where its claims come from.

💬should I rebalance?⌘K

✦ You're 2.5pp under target on NVDA and 2.2pp over on TSLA. Rebalancing both brings drift under 1pp across all four active theses.
