Question 761: Winning's in their blood

Borrowed from the world of gambling, __X__ is a term used to describe stocks of a company with a national reputation for quality, reliability and the ability to operate profitably in good times and bad.

Based on the idea that different tokens dictate different values ranging from lowest to highest, the phrase was coined by Oliver Gingold of Dow Jones sometime in 1923 or 1924. Company folklore recounts that the term apparently got its start when Gingold was standing by the stock ticker at the brokerage firm that later became Merrill Lynch. Noticing several trades at USD$200 or USD$250 a share or more, he said to Lucien Hooper of W.E. Hutton & Co. that he intended to return to the office to "write about these __X__ stocks." Thus the phrase was born. It has been in use ever since, originally in reference to high-priced stocks, more commonly used today to refer to high-quality stocks.
