RE:RE:RE:RE:RE:RE:RE:Peak-Oil Supply - on the Horizon...Pros work with Investment Statements....essentially the articulated discipline they will use for a particular fund....this sets up buy and sell and composition parameters...that "the client" (pension funds, large private wealth etc) who put their money in receive and agree to.
After that is is rigourous discipline and adherence to "the plan"...
For that they get paid quite well in management and performance fees....
Beautiful business....office rent, some equipment, knowledgeable people (huge bonuses) and their Bloomberg Terminals ....the latter are provided free by the trading organization that shaves a little off of every trade and still makes out like a bandit..aka Michael Bloomberg
The "fund" (could be an LP, mutual fund etc)...absorbs much of the cost of running it...includes trust companies (each fund is actually formally a "trust"...why you get T3s or in the case of an "LP" a T5013) and specialized accounting firms that do the fast reporting required for investors....
So I expect the mantra and answer to your questions is
"discipline, discipline, discipline"
