For several years, I worked on the copy desk at a financial news wire. The learning curve for such a job was steep. I didn't know a basis point from a bond issue, let along the difference between a put and a call. I saw so many acronyms and abbreviations it made my head swim. And, it was during one of my shifts that I and dozens of other editors and reporters froze in horror, watching our computer screens as the Dow Jones Industrial Average fell about 600 points in five minutes during the infamous "Flash Crash."
