Its tied to bond traders. It was the first system to list all the important information required to trade bonds. While it does other things as well. Its really bond traders that value a Bloomberg Terminal most. You notice that you can see stocks on almost any system. You rarely see specific bonds listed.
Its funny how opaque the bond market is.
There are large bid-ask spreads, and information is hard to find.
At the same time, the magnitude of the debt market is much larger than the stock market. It’s not surprising when you realize that most companies carry a lot of debt compared to their equity.
There are several times as many bond issues as there are outstanding types of stocks... maybe ten times as many. And, the volume of trading in most bond issues is smaller than most listed stocks.
That’s why, aside from Treasury issues, most bond trading is done by professionals. The bid-ask spread is too large. Retail investors invest via funds, such as ETFs or mutuals.
