An investment journal for your long-term portfolio
Trades and long-term investments deserve different tools. Meridian gives your buy-and-hold portfolio its own journal — cost basis, unrealized gains, sector exposure, and AI insight — synced straight from your brokerage.
Start free →Investing is not trading — so why journal it the same way?
A day trade and a five-year hold are different decisions with different timelines, and mixing them makes both harder to read. Meridian separates your active trades from your long-term investments into two journals, so short-term noise doesn't distort your investing picture and your investments don't clutter your trading stats — while still rolling up into one unified portfolio view.
What your investment journal tracks
Cost basis & market value
Every lot's average cost, current value, and how much you're up or down.
Unrealized P&L
Live gains and losses in dollars and percent for each holding.
Sector exposure
See how concentrated your portfolio is and where your risk sits.
Dividends & cash flow
Income and cash movements captured alongside your positions.
Your thesis
Notes and tags on why you own each position, so review is honest.
Goals
Portfolio and profit targets tracked automatically over time.
Synced from your brokerage
Connect brokerages such as Robinhood and Webull via SnapTrade and your holdings stay current automatically — or bring any broker's history in with universal CSV import. No more updating a spreadsheet every time a position changes.
With AI insight on your holdings
Meridian's AI coach reviews your investments too — flagging concentration risk, explaining what's driving a position, and helping you stay disciplined to your long-term plan instead of reacting to every headline.
