The New York Stock Exchange (NYSE) is one of the world's largest and most complex financial systems, uniting buyers and sellers to conduct stock trades in an interconnected and dynamic market. The exploratory problem is why, in certain months, mainly January, underperforming stocks start outperforming their entire previous year's value by a significant amount. This analysis aimed to understand the agents and behaviours that decide which stocks increase in price and how the magnitude of the increase is achieved.
