Controlling Traders  Trader Compensation (incentive fees) provides an option like remuneration  if the trader is successful, he can become a millionaire at a very young age  if the trader loses money, he is simply fired (in many cases, the trader will find another employment ...)

 The trader who is long in "option" has an incentive to increase the value of his option by increasing the risk of the positions ..  this may not be the best interest of the company

Daniel HERLEMONT

Controlling Traders  Trader risk taking can be controlled  by modifying the structure of the compensation contract to align the interests of the trader and the company better (e.g. by paying with company stock or tying compensation on long term performance, in case of hedge Fund, the trader should have a significant part of its wealth invested in the fund)  by substracting risk based capital charge from trading profits as in a RAROC type system  by appointing an independent risk manager

 To be effective, it is essential that the compensation structure of risk managers be independent of how well traders will perform  unless risk managers participate also in risk adjusted optimization processes of the strategy

Trader Limits  Stop Loss limits  restrictions on traders positions that are imposed after loses  prevent the trader to take bigger bets in the hope of future gain to wipe out previous loses.

 Exposure Limits  VAR Limits  are now becoming a common limit potential drawback: VAR limit is affected by volatilities and how they are determined. Volatility may have spikes and VAR limits may be violated Daniel HERLEMONT
