What are Mark-to-Market Losses?
How Do Mark-to-Market Losses Work?
Mark-to-market losses appear when an asset is priced according to a mark-to-market (MTM) accounting method. Under MTM, an asset's value is adjusted on a daily basis to reflect its market price. In other words, an asset experiences a mark-to-market loss if its market price falls from one business day to the next. For example, a mutual fund sustains a mark-to-market loss if its net asset value (NAV) falls from $1,200 at the end of trading on Monday to $1,100 at the end of trading on Tuesday.
