This repo contains all code related to my work using Hidden Markov Models to predict stock market prices. This initially started as academic work, for my masters dissertation, but has since been a project that I have continued to work on post graduation.• Used simulated data of a credit card user to train a Hidden Markov Model and estimated transition probabilities and emission probabilities using Forward-backward algorithm and sequentially predicted whether the upcoming transaction is fraud or not with recall= 0.81 and F1 - score = 0.67. In the previous article on Hidden Markov Models it was shown how their application to index returns data could be used as a mechanism for discovering latent "market regimes". The returns of the S&P500 were analysed using the R statistical programming environment.
