This page gives you an overall picture of the various calculations that take place on Börsdata.
The goal of Börsdata is to be able to analyse companies and have as many different calculations as possible for a company. Each calculation gives some information about the company; together they allow for an understanding that you as an investor can use in your decision-making process.
Different types of calculations
All calculations start with the company's report data and share price. The data used depends on the key figure.
Many key figures use a combination of report data and share price, but there are key figures that are only calculated using report data, and key figures that are only calculated using share prices (technical analysis).
The share price can be calculated with the latest, highest and lowest value, depending on whether we calculate history or the latest current value.
Share price- Latest value
The latest value is calculated using the latest TTM report data and the latest share price. For companies where we have intraday information(day rates), the value is continuously calculated during the day. For companies where we only have closing prices (End-Day), values are calculated once a day.
Share price - Historical data
The historical data for a key figure is usually calculated using the year's report data and the average value of the reporting period's share price.
If we calculate P/E for 2019, we use the full-year report for 2019 (Earnings per share) and the share price average for 2019.
Many key figures (such as P/E) can also be calculated at the Highest or Lowest share price to see how the key figure has changed during a year. This can create a so-called trend channel.
Share price - Maximum value
Historical key figures can be calculated using the maximum share price for the reporting period, i.e. the highest value that the share price has reached during that period.
Share price - Minimum value
Historical key figures can be calculated with the report's minimum share price during the reporting period, i.e. the lowest value that the share price has had during that period.
Calculation of average
The average value over three years is the same as the average over the last three years.
Seeing the average value of e.g. P/E over the last three years can reveal some interesting insights. It removes strong movements for an individual year, and can provide a fairer value, especially in Screener for comparisons of hundreds of companies.
For growth (development), we use a calculation called CAGR. CAGR abbreviates Compound Annual Growth Rate and is an accepted growth calculation for equities. CAGR shows the percentage return received on the company during a selected period.
Several key figures can be used to calculate the sum over several years. The sum is all values during the selected period.
When screening companies, for instance, seeing the total Dividend over 5 years can reveal interesting insights.
Key figures for technical analysis are calculated entirely using share price data. Common key figures are RSI or Moving Averages.
