The Covid-19 pandemic has made a significant impact on both the stock market and the <br/>global economy. The resulting volatility in stock prices has provided an opportunity to examine <br/>the Efficient Market Hypothesis. This study aims to gain insights into the efficiency of markets <br/>based on stock price performance in the Covid era. Specifically, it investigates the market’s <br/>ability to anticipate significant events during the Covid-19 timeline beginning November 1, 2019 <br/>and ending March 31, 2021. To examine the efficiency of markets, our team created a Stay-at-Home Portfolio, experiencing economic tailwinds from the Covid lockdowns, and a Pandemic <br/>Loser Portfolio, experiencing economic headwinds from the Covid lockdowns. Cumulative <br/>returns of each portfolio are benchmarked to the cumulative returns of the S&P 500. The results <br/>showed that the Efficient Market Hypothesis is likely to be valid, although a definitive <br/>conclusion cannot be made based on the scope of the analysis. There are recommendations for <br/>further research surrounding key events that may be able to draw a more direct conclusion.
