The p-value of 0.1 indicates that the relationship is insignificant at the 95% confidence interval.

Between June 2019 and January 2023, the monthly returns of the Vanguard S&P 500 Index ETF and Hormel Foods had a positive correlation of 0.24. But between September 2020 and August 2021, the correlation was a negative 0.13 (Exhibit: 3). This was when stocks such as Apple, Microsoft, Amazon, and Tesla went on an epic, once-in-a-lifetime run into the trillion-dollar club in terms of market capitalization. Consumer staples stocks such as Hormel Foods went out of favor during this period, dropping 10.8%.

Hormel Foods may be the perfect stock to own during a bear market. Its low volatility and, at times, negative correlation with the S&P 500 Index means it performs well when the markets perform poorly.  
 

     

Clorox's Poor Average Monthly Returns

Clorox makes household products such as wipes, sprays, and bleach (Exhibit 1).

Over the past decade, Clorox has underperformed compared to the S&P 500 Index. An analysis of the monthly returns of Clorox and the Vanguard S&P 500 Index ETF between June 2019 and January 2023 shows that Clorox continued its poor performance. Clorox's monthly return averaged 0.1%, while the Vanguard S&P 500 Index returned 1% (Exhibits 2 & 3). Even the third quartile average monthly return of 3.2% of Clorox fell below the 4.8% returned by the Vanguard S&P 500 Index ETF (Exhibits 2 & 3).

Change in Correlation of the Monthly Returns of Generac Holdings and the Vanguard S&P 500 Index ETF

Generac Holdings (GNRC) has a beta of 1.19 based on a linear regression model of the monthly returns of the Vanguard S&P 500 Index ETF (VOO) and Generac Holdings. The company's residential sales slowdown has pushed the stock lower over the past five months. The stock has dropped 55% compared to a 7% drop for the Vanguard S&P 500 Index ETF over the past year. This massive underperformance of the stock has led to a drop in the monthly return correlation of the Vanguard ETF and Generac Holdings.

The coefficient of VOO_Monthly_Return (slope of the regression line) is the stock's beta. This beta value means that for every 1% change in the monthly returns of the Vanguard S&P 500 Index ETF, Eastman Chemical, on average, changes by 1.54% (monthly). This relationship between the two companies is significant at the 95% confidence interval, given the p-value of 5.02e-10.

This close positive relationship between the two explains why Eastman Chemical has lost 25.6%, while the Vanguard S&P 500 Index ETF (VOO) has lost 14.5%.

The Pearson correlation of the monthly returns is a positive 0.46. This correlation value can be considered to have medium strength. This correlation is statistically significant at the 95% confidence interval with a p-value of 0.0057.  

A linear regression of the monthly returns of Reynolds and the Vanguard S&P 500 Index ETF yields a beta value of 0.44.

Monthly Return Comparison Between Cummins and Vanguard S&P 500 Index ETF

The following chart shows the Vanguard S&P 500 Index ETF (VOO) monthly returns on the x-axis and Cummins (CMI) on the y-axis. The regression line on the graph shows a steep slope, and the Pearson correlation value is 0.7. This value shows a very strong correlation between the monthly returns of the Vanguard S&P 500 Index ETF and Cummins. The p-value is significant at a 95% confidence interval. Cummins has returned 13.9% in the past year, while the Vanguard S&P 500 Index ETF has returned a -12.4%.

Cummins has a beta of 0.99 (nearly 1). Given this beta, Cummins, on average, moves in line with the S&P 500 Index. The adjusted R-squared value of 0.48 shows that about 48% of Cummins' monthly returns can be attributed to the returns of the S&P 500 Index. The p-value of 2.84e-07 shows that the regression analysis results are significant at the 95% confidence interval.

The average monthly return for Cummins between June 2019 and October 2022 was 1.49%. A one-sample t-test shows that the monthly return falls between -1.05% and 4.04%. But, the p-value of 0.99 is much higher than 0.05. This t-test may not be significant in the 95% confidence interval.

# Step 1: 

# Copy Dataframe Column CMI_Monthly_Return into a List

# CMI_Monthly_Return_Col is a list object, but needs to be numeric
