I have a bit of a problem understanding the stock market price listings for the London stock market. I am mainly concerned with Argentinian government bonds. So far, I have always used the Investor's Monthly Manual for bond prices. That was fine as long as I only needed monthly data. However, I now need daily data. So I turned to the London Times for bond prices. However, there the bond prices are listed in a somewhat different format. In order to check whether I understand these prices I tried to check the Times prices against the Investor's Monthly Manual (IMM) prices. However, I cannot really make sense of it. For example, if I look up the last day price of the Argentinian 1886-1887 loan for November 1911 in the IMM, I get 104.5. See here: https://imgur.com/a/6cdMKWs
If I look up the same bond in the "Business Done" section of the Times I get the following prices: 29 Nov 1911: 104 7/8 3/8 and 1 December: 104 7/8 1/2 [the 30 Nov issue does not have any bond price listings]. Here are the pages from the Times: https://imgur.com/a/vt17mWx https://imgur.com/a/J2LZbL4
I would be grateful for any advice as to how to read the bond prices with the double fractions in the Times and for any explanation why there is a difference between the IMM and Times.
