If the Cusip value is unique, it is a valid candidate for the Key value in a dictionary. Then you can use ContainsKey to perform your lookup. That will be about as fast as you can get.

Correct. The key must be unique but you can have the same value for multiple keys and lookups are fast (uses hashed keys behind the scene). Just try and ask if you see an actual problem.
