Simulating Interest rates using CIR and HJM While we can club equity, commodity and currency simulators in one category, interest rate simulators are a completely different animal. First because there is more than one way of modeling interest rates Equilibrium models and Arbitrage free models.
Monte Carlo Simulations Excel My first interaction with a Monte Carlo simulation was not a very pleasant experience. It was a exam problem based on a difficult text book and an even more incomprehensible study note that I had hardly understood. But over the years
Computational Finance: Monte Carlo (MC) Simulation method: Understanding drift, diffusion and volatility drag
We have introduced our friend mu (u) as drift and sigma as diffusion (or standard deviation or volatility or vol). In the previous session we have also gone out and built a simple excel based Monte Carlo simulation model for generating stock prices. While the
Extending MC simulation models to Currencies & Commodities Extending the original Monte Carlo (MC) Simulator for Equities to Currencies and Commodities required a few simple changes. Rather than using just r, we now use an adjusted r for the model. In the case of currencies
Computational Finance: Building your first Monte Carlo (MC) simulator model for simulated equity prices in Excel
Here is a slightly revised model for calculating the change in price of an equity security. We now add one more component to our generator function. While the first term works off expected return the second term will help us model uncertainty. Since in our world we drive and link uncertainly with volatility, our model also uses a factor proportional to volatility.
