The Belgian index is a good gauge of the economic situation in Belgium. Companies included in the index are, for example, KBC and Umicore. The BEL20 has the same trading hours as the regular stock market. This means that the stocks connected to the BEL20 can be traded from 9:00 AM to 5:30 PM. However, some brokers also allow trading in the BEL20 outside regular hours. The transaction fees can then be higher, since trading volumes are lower.
