database

Let's say we have a [Valuations] table containing several values per date and per fund:
-FundId
-ValDate
-Value1
-Value2...

The Primary key is obviously FundId+ValDate.
I have also indexed the ValDate field since I often query for values on a specific date.

My question is: should I also create a specific index for the FundId, or is MsAccess clever enough to use the Primary key when querying on a specific FundId ?
