I found the stock symbol for Berkshire Hathaway Class B shares listed as "BRK-B" in the dataset, along with other related symbols such as "BRK-A" for Class A shares and various others that include "BRK" in their symbols. Now, I will proceed to calculate the correlation distribution of daily closing prices between "BRK-B" and all other stocks listed in the dataset. ​​

The correlation coefficients between Berkshire Hathaway Class B shares ("BRK-B") and other stocks listed have been calculated. These coefficients range from strong positive correlations (close to 1) to strong negative correlations (close to -1), indicating a variety of relationships in terms of daily closing prices.

Next, I will plot the distribution of these correlation coefficients to visualize the frequency of each correlation range and then calculate the skewness and kurtosis for further analysis. ​

The distribution of correlation coefficients for Berkshire Hathaway Class B shares ("BRK-B") with other stocks shows a variety of relationships. The skewness of the distribution is approximately 0.26, indicating a slight bias towards higher correlation coefficients, but overall suggests a fairly symmetrical distribution. The kurtosis is approximately -1.38, suggesting that the distribution is somewhat flatter than a normal distribution, with fewer outliers than expected in a normal bell curve.

This analysis reveals that "BRK-B" has a diverse range of correlations with other stocks, from strongly positive to strongly negative, with a slight tendency towards positive correlations. The relatively flat distribution implies a broad spread of correlation values, indicating varied relationships in terms of daily closing prices with other stocks listed.
