One thing I don’t like about Factset is that there are a ton of formulas in their formula database, but finding the right one can sometimes feel like finding a needle in a haystack. What I mean by that is that, for example, there could be 5 different formulas for LTM EBITDA, and 3 of them return #N/A, and the other two give you different results.
As for fixed income, I have very little experience in this realm, so take what I say lightly. Factset seemed okay at providing the various debt issues for each company, and would provide maturities and coupon rates. Yields seemed hard to come by, and credit spreads… not really available. I looked for a way to determine corporate credit spreads for a model around last year (before Factset switched their research database provider) and came up empty. Maybe I’ll take some time to explore it a little deeper, I just haven’t done too much with FI.
