I'm reading The Intelligent Investor by Benjamin Graham, and I came across the text below.
What I don't understand is: if the issues sold at 60 through 1970 but closed at 77 that year, wouldn't that mean they are selling at a premium? Why does the author say the issues are sold at a discount?
In 1970 it was possible to buy a number of old issues at large discounts. Some of these are accepted at par in settlement of estate taxes. Example: The U.S. Treasury 3(1/2)s due 1990 are in this category; they sold at 60 in 1970, but closed 1970 above 77.
Thank you for reading!
