Undergraduate Economic Review


This thesis investigates whether sports outcomes for New York City based teams affect the daily returns, volatility or trading volume of major stock indexes in the United States. I research whether events that affect local mood in a major financial center can influence national stock indexes by swaying the sentiment of workers in the financial sector. By performing an event study I found evidence that returns are abnormally high following championships won by New York City professional sports teams. Returns are abnormally low and volume is abnormally high following elimination from a championship round.
