If you are at a larger investment bank, you will have various paid data sources at your disposal. These include:
- Bloomberg
- CapitalIQ
- FactSet
- Mergr
For those that are not at a larger bank, one can use the free sources of financial data including:
- Yahoo Finance
- Google Finance
Yahoo Finance and Google Finance get their EBITDA numbers from CapitalIQ and their analyst EPS consensus estimates from there as well.
Investment banks typically do not want you to use the EBITDA from CapitalIQ, Bloomberg, FactSet and would prefer that you spread the comps individually to get to EBITDA.
We are ultimately using the financial data sources to build and maintain our various indices associated with our coverage group.
