Value at risk.

It is the probability that a portfolio will experience a mark-to-market loss that exceeds that of a specific predetermined threshold value.

ABSTRACT. – We propose a semi-parametric method for unconditional. Value-at-Risk (VaR) evaluation. The largest risks are modelled parametri-. To specify a value-at-risk metric, we must identify three things: The period of time over which a possible loss will be calculated—1 day, 2 weeks, 1 month, etc. This is called the value-at-risk horizon.

In finance, a return is a measure of economic benefit from holding assets. If an asset’s value is EUR 50 one month and EUR 55 the next month, we might say the asset had a 1-month 10% return.
