Random numbers drawn from a particular probability distribution (i.e., random variates) are frequently needed in many fields, particularly for simulations. There are many algorithms for generating random variates, but I will focus on one simple technique that can be used with some built-in Excel functions. This technique is known as the Inverse Transform Method. For our purposes, we want to…
The article demonstrates randomness in stock price movements using an Excel simulation inspired by A Random Walk Down Wall Street by Burton Malkiel. It starts with a simple model based on coin tosses, where a "head" causes the price to rise and a "tail" causes it to fall, mimicking the unpredictability of markets. The article then uses geometric Brownian motion for more realistic modeling. Excel functions and VBA are employed to generate data and create high-low-close stock charts, showing that many technical patterns can emerge purely from random processes.
