Frequently asked questions
How can I track my stock portfolio for free?
Create a free Mercurys account, add your positions (stocks, ETFs, crypto) manually or import your broker PDF statements. You'll instantly see performance, sector and geographic breakdowns, and the total value of your PEA, CTO, or life insurance portfolio.
What is AI portfolio analysis?
Mercurys' AI analyzes your portfolio to assess diversification, fees (ETF TER), correlations between your assets, and recommends cheaper or more diversified alternative ETFs. Available 3 times a month on the free plan.
How does movement analysis work?
When your portfolio moves, AI breaks down performance by asset (attribution), searches relevant financial news via Tavily, then synthesizes the macroeconomic context, per-asset explanations with sources, and analyst outlooks. You can analyze from the latest high, the latest low, this month, or this quarter.
How do I get price alerts on stocks and ETFs?
On the Explore page, select an asset and set a price alert (above or below a threshold). Mercurys checks prices twice a day and emails you as soon as the threshold is hit. Up to 15 alerts on the free plan, 40 on premium.
How do I build an ETF portfolio suited to my profile?
The Mercurys AI composer builds a custom ETF portfolio based on your risk profile (defensive to aggressive), geographic and sector preferences, tax wrapper (PEA, CTO, AV), and investment horizon. You can then simulate a DCA on historical data.
Is Mercurys suitable for investing beginners?
Absolutely. The "Learn" section covers everything: investing basics, ETFs, tax wrappers (PEA, CTO, life insurance, PER), portfolio building, DCA, and a detailed FAQ. The interface is designed to be intuitive even with no experience.
Which tax wrappers are supported?
Mercurys supports the PEA, the CTO (ordinary securities account), life insurance (AV), the PER (retirement savings plan), the PEE (employee savings plan), and crypto portfolios. Each position is tied to its wrapper for precise tax tracking.
Can I import my positions from a broker?
Yes, Mercurys reads your broker PDF statements (Boursorama, Degiro, Trade Republic, Fortuneo, Bourse Direct, etc.) and automatically extracts your positions with AI. You can also import via CSV or Excel file.
