It may have changed recently but that's not quite how the restrictions worked on Wall St in my experience (8yrs in the front office at Goldman). There are lots of restrictions to the point where owning broad funds often becomes simpler, but you can do single-stock trades etc if you want to.

See another comment where I explain more but how it used to work for me was you have to trade through the employee trading desk (and aren't allowed to have unmonitored brokerage accounts) then any trade gets vetted against various lists (some but not all of which are available to you ahead of time to protect deal confidentiality) and then there are static criteria about how long you have to hold particular positions etc.
