I worked there in a past life, still miss having access to the terminal. Ive always wished they launched a consumer version for <100 USD a month.
For bond trading and analytics, often no one has the data other than Bloomberg. INTEX has a lot of MBS and ABS data, Trepp has CMBS data, and I guess there are some muni and corporate specialists, but Bloomberg has it all and at your fingertips with an ergonomic UX, and any analytics you can think of. If you want to actively trade fixed income, you just can't do it without a Bloomberg.
From the dumbest things to the really esoteric like filings of some obscure Hong Kong based firm or data on plasma waste to power projects in XYZ region.
Bloomberg is pretty absurd.
I love it!
2. Availability of information under one symbol space allowing you to create views that pulls in information about very disconnected fields.
3. A company wide focus on converting things into "symbols". Most memorable example was the symbol for number of kidnappings in Mexico. The breadth of data available is truly impressive.
not as extensive but pretty good.
