CONCLUSION Our study has proven successful in detecting continent-wise and sector-wise extreme events (EEs) in the stock market using Topological Data Analysis (TDA). The 2008 financial crisis and the crash due to the COVID-19 pandemic are identified as EEs in Asia, Europe, North-South America, and Oceania continents. A sector-wise analysis has been carried out during the COVID-19 pandemic. Earlier work has identified the crash due to COVID-19 as an EE taking the stock indices of each country separately proving it to be unsuitable for analyzing continent-wise or sector-wise. However, TDA overcomes this difficulty and we can identify continent-wise & sector-wise EE by analyzing stock prices of n stocks/indices together. n Our results are consistent with the empirical mode decomposition-based Hilbert-Huang transform technique used for the identification of EEs by Mahata et al.[10] and Anish et al.[13]. Hence, TDA is capable of identifying EEs in the stock market. In the future, TDA may be applied with machine learning techniques to understand the market dynamics and also may help in the prediction of stock prices.
