Beginning Market Value (BMV)

The value of an asset at the start of a time period (i.e., stocks at the start of a trading session or real estate upon appraisal).

Hans wanted to impress his neighborhood crush, Gertrude, who liked German cars. So he went to visit a buddy who sold knock-off merchandise like "Lewis Vuittoon" bags and "Tug Hewer" watches and bought a BMV (similar to a BMW but with minor logo tweaks) for $2,000 (its beginning market value).

Turns out Gertrude is more of a Volkswagen fan, so Hans returned the car the next day, receiving its ending market value of $500 (because of depreciation), which then becomes the next day's beginning market value.
