Abstract: The stock market volatility can be measured by the implied volatility of options. To analyze the British stock market volatility before and after the NYSE stock market crash in 1929, we looked into the options price data across different sectors in the British stock market and calculated the implied volatility based on the stock bid price using Black Scholes Merton Option Pricing Formula. We found that there was a significant increase in implied volatility after the Great Depression in 1929 overall. Among oil, rubber, and newspaper sectors, we also found a significant increase in implied volatility. Future work will focus on collecting more data after 1929 to consolidate the conclusions found. Besides, it will also be interesting to calculate the implied volatility for US stocks traded in London to see if there is a meaningful implied volatility difference between US stocks and British stocks traded in London.
