Imported LYNX portfolio summary in Portseido with daily and all-time returns

Real return, dividend calendar, and allocation, visible the moment the import finishes.

01 · True performance

Am I beating the market, or just depositing more?

Portseido separates your skill from your savings. We compute Time-Weighted Return (TWR), the return your decisions actually produced, alongside Money-Weighted Return (MWR), which includes the effect of your contributions.

Then we benchmark both against S&P 500, NASDAQ, or any index you pick, in your own currency.

02 · Dividend calendar

See your LYNX dividend income, month by month.

Every dividend is detected from your import and projected forward. See the calendar by timeframe, by holding, or by currency, plus your projected annual income and how it's growing year over year. Prefer a dedicated dividend-only view? See the LYNX dividend tracker.

LYNX questions, answered.

Is my LYNX data safe?

Portseido only reads the CSV file you choose to upload. We never have access to your LYNX account, password, or any trading API. You can delete your data in one click.

How often do I need to re-import?

Depends on how up-to-date you prefer. In most cases, once a month is enough. Prices update daily, automatically. Only new trades, dividends, and fees need a fresh CSV export.

How are currency conversions handled?

Portseido automatically tracks the foreign-exchange effect on your holdings and consolidates everything into the base currency you choose, so your total return is consistent across markets.
