Complex Trading: Options schedule in K vs bloomberg

[wstguest]

Hi,

1.
I understand using bookvalue for debt as opposed to market value because they're very similar, but is this the same case for options? (I have never used a Bloomberg so I don't know whether bloomberg provides options schedule) Why do we use 10-K if we want the most up-to-date info?

How does this differ in public vs deal comps?

2.
I think I learned elsewhere that one can dynamically link the current stock price to a service provider on the excel sheet so that everything updates by pressing F9. Is this the case? Are there pros/cons to this? Why do we statically input the stock prices for the public comps (and other models)?

Thanks

1) Options are provided from the 10K. Whenever possible, get your inputs from the source. Bloomberg, like other data vendors, are aggregators. Options are only sometimes provided on 10Q, hence we get it from the 10K because we don't have other updated information to update from. No difference between public vs deal comps.

2) Correct, you can use a variety of data vendors to accomplish this. In our learning modules, we are data vendor-independent so it is hard coded. However, if you or your firm subscribes to such a data vendor, you would link it in.
