Types of Sensitivity Analysis
Understanding the different types of sensitivity analysis is crucial for any investor looking to master risk management in options trading. In this section, we will delve into three primary types of sensitivity analysis: local sensitivity analysis, global sensitivity analysis, and Monte Carlo simulation.
Local Sensitivity Analysis
Local sensitivity analysis focuses on examining the impact of small changes in one parameter at a time on the outcome of the model. This method is beneficial for understanding how individual variables influence the performance of an option strategy.
In options trading, local sensitivity analysis can be applied to evaluate how minor adjustments in variables like implied volatility, interest rates, or underlying asset prices affect the pricing and risk of call options or put options.
| Variable | Change (%) | Impact on Option Price (%) |
|---|---|---|
| Implied Volatility | +1% | +2.5% |
| Underlying Asset Price | +1% | +1.8% |
| Interest Rate | +1% | +0.5% |
Global Sensitivity Analysis
Global sensitivity analysis, as opposed to local sensitivity analysis, considers the impact of varying multiple parameters simultaneously across their entire range of possible values. This provides a more comprehensive understanding of the factors affecting an option pricing model and is particularly useful for complex financial instruments like covered calls.
Global sensitivity analysis helps investors identify the key drivers of risk and return in their options portfolio. It enables them to prioritize the most critical factors influencing their trading strategies and make informed decisions under uncertainty and risk (Corporate Finance Institute).
| Parameter | Low Value | High Value | Sensitivity |
|---|---|---|---|
| Implied Volatility | 15% | 30% | High |
| Underlying Asset Price | $50 | $100 | Medium |
| Interest Rate | 0.5% | 3% | Low |
Monte Carlo Simulation
Monte Carlo simulation is a robust tool used to model the probability of different outcomes in a process that cannot easily be predicted due to the intervention of random variables. In options trading, Monte Carlo simulation allows investors to conduct a large number of simulations to understand the potential range of outcomes for an option strategy.
Monte Carlo simulations generate a wide array of possible scenarios by varying all relevant parameters simultaneously and observing their impact on the option's performance. This method is particularly useful for assessing the risk and profitability of complex trading strategies, such as credit spreads and vertical spreads.
| Simulation | Outcome Probability | Expected Return |
|---|---|---|
| 1 | 0.2 | $100 |
