Let's go step-by-step through each part of the problem using the given data from the stock table.

Part 1a:

The symbol for Company XYZ stock is XYZ (already provided).

Part 1b:

To find the price per share at the end of the day yesterday, use the following:

• Last price: $15.89
• Change: +$0.38

The price at the end of yesterday would be the current price minus today's change: $\text{Yesterday's price} = 15.89 - 0.38 = 15.51$ Thus, the price per share at the end of yesterday is $15.51 (rounded to the nearest cent).

Part 1c:

To find the total value of the shares traded today, use:

• Volume traded: 68,000,000 shares
• Current price: $15.89

The total value of shares traded today is calculated as: $\text{Total value} = \text{Volume} \times \text{Current price}$ $\text{Total value} = 68,000,000 \times 15.89 = 1,080,520,000$ Rounded to the nearest million: $\text{Total value} = 1,081 \, \text{million}$ Thus, the total value of shares traded today is $1,081 million.

Part 1d:

To find the percentage of all Company XYZ shares that have been traded today, use:

• Volume traded: 68,000,000 shares
• Shares outstanding: 5,485,000,000 shares

The percentage of shares traded is calculated as: $\text{Percentage traded} = \left(\frac{\text{Volume}}{\text{Shares outstanding}}\right) \times 100$ $\text{Percentage traded} = \left(\frac{68,000,000}{5,485,000,000}\right) \times 100 = 1.24\%$ Thus, 1.24% of all Company XYZ shares have been traded so far today.

Part 1e:

To find the total dividend you would expect to receive for the year, use:

• Number of shares owned: 50 shares
• Dividend yield: 18.63%
• Current price: $15.89

First, calculate the annual dividend per share: $\text{Dividend per share} = \text{Dividend yield} \times \text{Current price}$ $\text{Dividend per share} = 0.1863 \times 15.89 = 2.96$ Now, calculate the total dividend for 50 shares: $\text{Total dividend} = 2.96 \times 50 = 148.00$ Thus, the total dividend you should expect to receive this year is $148.00.

1. How do we calculate the change in stock price based on the day's performance?
2. What does the P/E ratio indicate in the stock table, and how is it used?
3. How would a different dividend yield affect your expected total dividend?
4. How can stock volume affect the stock price during the day?
5. How does the market capitalization relate to the company's overall stock value?

Tip: When calculating percentage changes or yields, always ensure you have the correct base value (in this case, the current price) for accurate results.
