Yesterday’s question was: “On the stock exchanges, companies are known by their ticker symbols: two- or three- or four-letter codes denoting the companies. With 26 possible letters in each slot, there are a very large number of possibilities. But there are also 20 companies with single-letter ticker symbols. How many of them can you name?”

The answer is:

A = Agilent Technologies (an analytical instrument manufacturer, headquartered in Santa Clara, California)
B = Barnes Group (an industrial and aerospace manufacturer and service provider, headquartered in Bristol, Connecticut)
C = Citigroup
D = Dominion Energy (a power and energy company, headquartered in Richmond, Virginia)
E = Eni S.p.A. (an Italian multinational oil and gas company)
F = Ford Motor Company
G = Genpact (a professional services firm, headquartered in New York City)
H = Hyatt
J = Jacobs Engineering Group (a technical professional services firm, headquartered in Dallas, Texas)
K = Kellogg’s
L = Loews Corporation (an American conglomerate holding majority stakes in Altium Packaging, Boardwalk Pipeline Partners, CNA Financial, Diamond Offshore Drilling, and Loews Hotels)
M = Macy’s
O = Realty Income Corporation (a real estate investment trust, headquartered in San Diego, California)
R = Ryder System Inc. (a transportation and logistics company, known for its rental trucks)

Ian’s Tough Trivia is a daily feature of this blog. Each day, I post a tough question, as well as the answer to the previous day’s question. At some point, I’ll offer a prize for whoever has the most correct answers, and another for whoever participates most often (I’ll take into account people coming in after the start: regular participation starting later is just as good as regular participation starting earlier). There may also be a prize for the funniest or most amusing wrong answer. Simply comment on this post with your answer. I’ll approve the comments after the next question is posted. Sure, you can probably find the answers by searching the web, but what’s the fun in that?
