The research looked at how changes in oil prices and the economy affect the US stock market from 1990 to 2018. They used a method called Vector Auto-regression (VAR) analysis to study the data. The findings show that both oil prices and economic growth play a significant role in influencing the stock market. When oil prices go up, the stock market tends to rise as well. On the other hand, an increase in GDP can have a negative impact on the stock market.
