If there's a Black Friday, there's also a Black Monday in the financial dictionary. Black Monday ocurred in October 19, 1987 when world's stock market falls down as a result of the fall of US share prices. A lot of countries' economies has been affected by this world phenomena in 1987. I've noticed that every time something bad or negative happens to the world market, they will named it as black day. Perhaps, they used it to commemorate what happened to the finance world during these dates. I wondered, if there's a black Tuesday or Wednesday as well.
