Word Origin & History

X 
most Eng. words beginning in -x- are of Gk. origin or modern commercial coinages. E. Anglian in 14c. showed a tendency to use -x- for initial sh-, sch- (cf. xal for shall), which didn't catch on but seems an improvement over the current system. As a symbol of a kiss on a letter, etc., it is recorded from 1765. In malt liquor, XX denoted "double quality" and XXX "strongest quality" (1827). Algebraic meaning "unknown quantity" (1660 in Eng.), sometimes said to be from medieval use, originally a crossed -r-, probably from L. radix (see root). Other theories trace it to Arabic, but a more prosaic explanation says Descartes (1637) took x, y, z, the last three letters of the alphabet, for unknowns to correspond to a, b, c, used for known quantities. Used allusively for "unknown person" from 1797, "something unknown" since 1859. As a type of chromosome, attested from 1902. First used 1950 in Britain to designate "films deemed suitable for adults only;" adopted in U.S. Nov. 1, 1968.

X

1. A Nasdaq stock symbol specifying that it is a mutual fund.

2. A symbol used in stock transaction tables found on the internet and in newspapers to indicate that a stock is trading ex-dividends or ex-rights.

Investopedia Commentary

1. Nasdaq-listed securities have four or five characters. If a fifth letter appears, it identifies the issue as other than a single issue of common stock or capital stock.

2. Typically after a dividend is paid or a right is distributed, a stock's price will drop by a similar amount. Because of this, it's important for investors to be aware of when a distribution is made so that the depreciation in price is not mistaken for something else.
