Professional Risk Manager - PRM
  
See: Risk Manager. And yeah, they get paid for doing that function; it's not like golf or tennis hobbies.
In fact, risk management is a real profession. You have to actually get licensed to be a risk manager for, say, a hedge fund.
How's that work? Well, when a hedge fund raises money, they put in their trust indenture or investment papers to the limited partners giving them their dough that, if a given investment goes down more than 15% from time of purchase, no matter what, it will be sold. That's one way (not necessarily a good way) to manage risk. The stock can likely be bought back, say, 90 days later, or even the next day. But it must be sold so that further declines don't happen.
Clearly the analyst/portfolio manager got it wrong. They bought it early. Or badly. And now the risk that they are completely, totally bonkers to have wanted to be long this stock is enough that the risk manager steps in and demands those securities sold.
Lots of lawyers do this for a living. JD plus an MBA = good formula for whining about high taxes later in life.
