laatkoers

Laatkoers is a Dutch term whose literal meaning is “late rate” or “late price.” It is not a standard or official term in Dutch financial vocabulary. In most professional contexts, terms such as slotkoers (closing price) or koers (price) are used to describe the value at which an asset trades at a given moment or at the end of a trading period. Laatkoers may appear in journalistic prose or informal discussion to signal that a price was established late in the trading day or after-hours, but it lacks a formal definition in major financial glossaries.

Usage and interpretation of laatkoers vary, and readers should treat it as non-authoritative. In practice, it can refer to a price that emerges from late trades, after-hours activity, or a last traded price that is not necessarily representative of the official closing value. Because it is not standardized, it can lead to ambiguity about which price is being described—whether it is the last transaction, the price at a late-session print, or a value from after-hours trading.

Compared with slotkoers, laatkoers does not carry an explicit administrative or transactional status. Market participants rely on official data feeds that publish timestamps, volumes, and whether prices are real-time, delayed, or after-hours. When precision is required, sources should specify the exact nature of the price, such as last traded price, closing price, or after-hours price.
