How content is produced
Daily Brief
Written each weekday morning by an AI language model from that morning’s market data, and published automatically. It is not reviewed by an editor before it goes live.
Flash Intelligence
Short items written by an AI language model when automated monitoring picks up a European news headline. The model works from the headline, and every item is labelled “AI-generated”.
Explainer articles
Drafted weekly by an AI language model from a planned list of topics, and published without an editor’s review.
AI-written text can contain mistakes, including in how it describes a number. The figures on stock, ETF, ECB and bond pages are pulled directly from the sources above rather than written by a model. Treat the written pieces as market context and check the original source before relying on a detail.
Currencies
Each price is shown in the currency the share is quoted in, without conversion. Most listings are in euros (€). London-listed shares are quoted in pence sterling, shown with a “p” (100p = £1), and Stockholm-listed shares in Swedish krona (SEK).
What the indicators mean
RSI
A momentum gauge. It reads high after a run of unusually strong gains and low after unusually weak ones. Boursee labels the extremes “overbought” and “oversold”; both describe recent price action, not a forecast.
MACD
A trend-and-momentum indicator built from moving averages. The screener shows whether the trend is bullish or bearish and when the signal lines have just crossed.
SuperTrend
A trend-following line that adjusts to recent volatility. It shows whether the price is trading above (bullish) or below (bearish) that line.
Relative strength
How a stock has performed against its own index over the last 30 days. A positive number means it has outperformed the index.
Volume signal
Compares the latest trading volume with its recent average. “Surge” means volume was well above normal.
52-week range
The lowest and highest prices the share has traded at over the past year, and where the latest close sits between them.
Limits of the data
- Third-party data can contain errors or gaps. Where a figure is unavailable Boursee leaves it out, or labels it as reference data, rather than estimating it, so some pages show fewer metrics than others.
- The screener covers a fixed universe of European stocks and UCITS ETFs and does not include every member of every index.
- Indicators describe past price action. None of them predicts future performance.
- Boursee provides general information under Article 24 of MiFID II. It is not personalised investment advice and is not regulated by the AFM or FCA. See the full disclaimer.
