How to read it
Each box is a company inside its sector. The bigger it is, the more it is worth on the stock market (market cap). Green boxes are rising and red ones falling; the stronger the color, the bigger the move (color tops out at ±3%). Grey boxes have no recent price.
Each exchange shows its latest session: if it has closed (or not opened yet), the change is that of its last day. While it is open, it updates every 15 minutes.
With «MeridIAn score», the color is the 0-10 score our analysis gives each company: green, high score; red, low score.
