Some risks, called systematic risk, can be controlled or reduced while other market risk, which can take the form of a price shock, can never be eliminated.

This chapter covers a broad range of topics related to risk, including individual trade risk, portfolio risk, leverage, and a continuation of the effects of price shocks and catastrophic risk.
