Report for investment audit

What would be the simplest way to create a report for an investment audit that would report changes to show a snapshot of actions for a period of time?  

I just noticed the reporting module is not enabled, so the reporting wizard is not available.  Should I enable the report module and would the wizard be able to create this type of report?

I’m currently creating complicated views.  

Any information and assistance would be appreciated.

Thanks
