It is the rate of change of value with respect to the asset $$\Delta = \frac{\partial V}{\partial S}$$ Here V can be the value of a single contract or of a whole portfolio of contr Why hedge?

Delta hedging theoretically perfect elimination of all risk by delta hedging exploiting the perfect correlation between the changes in the option value and the stock price. → dynamic hedging continually monitored and frequently adjusted by the sale or purchase of the underlying asset. Gamma hedging To reduce the size of each rehedge and/or to increase the time between rehedges, and thus reduce costs, the technique of gamma hedging is often employed. Gamma hedging is a more accurate form of hedging that theoretically eliminates these second-order effects. Vega hedging Vega hedge means that we hedge one option with both the underlying and another option in such a way that both the delta and the vega, the sensitivity of the portfolio value to volatility, are zero. The distinction between variables (underlying asset price and time) and parameters (volatility, divide Static hedging In practice, hedging must be done at discrete times and is costly. On theoretical side, the model for the underlying is not perfect, at the very least we do not know parameter values accurately. Delta hedging is exposed to model risk. This is eliminated by static hedging as well as delta hedging. St Margin hedging Often what causes banks, and other institutions, to suffer during volatile markets is not the change in the paper value of their assets but the requirement to come up suddenly with a large amount of cash to cover an unexpected margin call. To cover the risk of default in the event of an unfavorable Crash (Platinum) hedging Market Crashes have at least two obvious effects on hedging The moves are so large and rapid that they cannot be traditionally delta hedged. The convexity effect is not small. Normal market correlations become meaningless. Typically all correlations become one (or minus one) Crash or Platinum hedgin 36 $$\text{Call option value} = SN(d_1) - e^{-r(T - t)}N(d_2)$$ $$d_1 = \frac{\log{(S/E)} + (r + \frac{1}{2}\sigma^2)(T - t)}{\sigma \sqrt{T - t}}$$ $$d_2 = \frac{\log{(S/E)} + (r - \frac{1}{2}\sigma^2)(T - t)}{\sigma \sqrt{T - t}} = d_1 - \sigma\sqrt{T - t}$$ 2024.03.13 블로그 검색 더보기 nasa.gov centers-and-facilities johnson NASA Names Deputy Station Manager, Operations Integration Manager - NASA to-day operations, maintenance, and research aboard the orbiting laboratory, taking over the position held by Contella.
