This research investigates the Russian stock market response to COVID-19 pandemic and compares how the reactions to it varied among the industries. The event study and Wavelet coherence were applied to answer the research question. It was discovered that the Russian stock market in general had a strong negative reaction to the COVID-19 outbreak.

However the response to the fi rst case was stronger than the response to the fi rst COVID-19
related death. It was also discovered that most of the industries reacted to the pandemic in line
with the overall negative reaction of the market, with transportation and fi nancial sectors demonstrating the most strong response. The returns of the different sectors showed high coherence during the fi rst wave of the pandemic that is another fi nding. However, the chemical sector reacted rather moderately to the COVID-19 and demonstrated lower coherence with the other sectors during the fi rst wave of the pandemic, so it might be benefi cial to include the stocks of the chemical companies in the portfolio for its diversifi cation. The results obtained have practical value for the investors (in terms of portfolio construction) and governmental regulators that are trying to mitigate the impact of the shocks on the stock market.
