the measurement of market risk has evolved form simple naive indicators that distort the measurement of risk, such as the face value or notional amount of an individual security, through more complex measures of price sensitivity such as the basis point value,to sophisticated risk measures such as the latest value at risk for whole portfolios of securities
in this chapter, we will explain the principles that lie behind value of risk and make clear that strengths and weaknesses of the approach in non mathematical language
we will also look at some specialist measures of risk for derivative (the Greeks)and at a key supplement to any value of risk approach:stress testing and worst-case scenarios.
