Discount/Premium to NAV
The discount/premium to NAV is a percentage that calculates the amount that an exchange traded fund or closed end fund is trading above or below its net asset value. This metric can be a valuable metric to track how far away a security is trading away from its true value. This is an important metric for closed end funds specifically because CEFs don't issue any additional shares after its initial offering. This can cause the price to stray away from the true net asset value of the holdings in the CEF.
