All the guides

1. Investing in shares: how it works The overview page: share, bond, ETF, where fees sit and what they cost (1% a year removes a quarter of the result over 30 years), the French wrappers and their rules, order execution, what “volatility” means. Basics Markets Fees Orders Read the guide
2. ETFs: what is inside a tracker, and how to read its fact sheet Physical or synthetic replication, invisible ongoing charges taken from the net asset value, tracking gap, distributing or accumulating share classes, reading the key information document. Two charts and six tables, with no product recommendation. ETF Fees Replication Documentation Read the guide
3. Dollar cost averaging: what spreading really does to the price you pay Six contributions worked out row by row: the price paid is the harmonic mean of the prices (€98.84), not their average (€100.83). Why it all comes from the fixed amount rather than the schedule, and the two cases where spreading costs 10.59% of the units. Calculation Regular investing Average cost Read the guide
4. Compound interest: why wealth does not grow in a straight line Interest earns interest, and the curve steepens. Over 30 years at a constant contribution, the last decade brings 51% of the final result, for the same monthly effort. Multiplication tables, a chart, and what these calculations do not say. Compounding Time Return Read the guide
5. Monte Carlo projections: what the calculation does, and what it does not say A methodology and limits page, with no recommendation of any kind. What a percentile really means, and sequence risk: the same returns, the same average, yet a 110,459 € gap depending on their order once there are withdrawals. Monte Carlo Projection Risk Read the guide
6. Calculating your net worth: do not forget the liabilities Assets minus liabilities, provided you subtract the right thing: the outstanding principal, not the payments still to come. On a typical mortgage the confusion is worth 46,500 €. With the valuation pitfalls and the shared ownership cases. Assets Liabilities Outstanding principal Read the guide
7. Amortisation schedules: understanding the outstanding principal Every payment splits into interest and principal, and the proportion shifts with each instalment. More than half the first payment goes to interest, and halfway through the term only 41 % of the loan is repaid. With the special cases and the statutory cap on early repayment indemnities. Loan Interest Amortisation Read the guide
8. Tracking dividends: dates, gross and net, yields Three dates, only one that decides your entitlement. Why the price falls mechanically on the ex-date without anything being lost, and why yield on cost (5.00 %) is not the current yield (3.33 %) on the same holding at the same instant. Dividends Dates Yield Read the guide
9. Create an AI API key and connect it to PMP AI analyses need a key you create with the provider of your choice. The three steps, the screen where it goes, the three causes behind a failed test, and why the key never travels through us. API key AI Getting started Read the guide
10. Import your transactions into PMP, step by step The full path: where to click, how an export holding several accounts is split without mixing a share savings plan and a securities account, the three checks that confirm everything arrived, and what is left if the format is not recognised. Import Step by step Getting started Read the guide
11. Importing your broker statement: what works and what breaks A positions statement is a photograph, a transactions statement is the film: only the second yields an exact cost basis. The eight fields a line must carry, the corporate actions that break imports, and the silent format traps. Import Broker Formats Read the guide
12. French capital gains: how the weighted average acquisition price works You added to a position at different prices and you are selling part of it: French law requires the weighted average, not FIFO. What that changes on the taxable base, with the arithmetic and the sources. Tax Weighted average Calculation Read the guide
13. Why your financial data does not have to leave your device A portfolio is cumulative, not revocable, and made of quasi-identifiers. What « anonymised » means against the CNIL criterion, what « local first » really implies, and the price of that choice: backing up is on you. Privacy Local first CNIL Read the guide
14. Glossary of wealth and market terms Sixty-four terms defined without jargon, from outstanding principal to sequence risk, each with its own anchor so it can be cited directly and linked to the page that develops it. Glossary Reference Read the guide
