Why are they called "Black"? I thought "Black" meant operating at a profit? Shouldn't days of big losses on the stock market be "Red" days?
Naw, I don't really expect an answer. It just seems like odd terminology to me.
Black is much more ominous, as in dark days...
Black was at one time a symbol of death- thus, the Grim Reaper wears black, and people wear black at funerals.
