4. A.Penjira Kanthawongs4 Project 2: BetNet Stock Club Michael Santos and 6 classmates began playing the stock game with Yahoo!’ s web site (quote.yahoo.com). Michael and his friends started with $100,000 each person to buy and sell stocks for 1 month.

5. A.Penjira Kanthawongs5 Yahoo! Web site awarded the top finisher a $5,000 cash prize. Michael and his friends won the contest. They used the prize money to start the BetNet Stock Club and decided to invest in real stocks.

6. A.Penjira Kanthawongs6 Each month, Michael summarizes the month-end financial status. As the club members approach graduation from college, the value of the club’s portfolio has grown to nearly $900,000. As a result, the members voted to buy a new computer and Microsoft Office 2000 for Michael. With Office 2000, he plans to create a worksheet summarizing the club’s stock activities that he can e-mail to the members.

7. A.Penjira Kanthawongs7 Michael has asked you to show him how to create the workbook and access real-time stock quotes over the Internet using Excel 2000.

8. A.Penjira Kanthawongs8 Project 2: BetNet Stock Club Need: An easy-to-read worksheet that summarizes the club’s investment (Figure 2-1a). It includes each stock’s … name, symbol, date acquired, # of shares, initial price, i-cost, current price, c-value, gain/loss, % gain/loss. It also includes totals, average, highest value, lowest value for each column of #.

9. A.Penjira Kanthawongs9 Michael wants to use Excel to access real-time stock quotes using Web queries (Figure 2-1b).

10. A.Penjira Kanthawongs10 Source of Data: The data supplied by Michael includes the stock names, symbols, dates acquired, number of shares, initial prices, and current prices.

11. A.Penjira Kanthawongs11 Calculations: 1. Initial Cost = Shares x Initial Price 2. Current Value = Shares x Current Price 3. Gain/Loss = Current Value - Initial Cost

12. A.Penjira Kanthawongs12 4. Percentage Gain-Loss = Gain-Loss / Initial Cost 5. Compute the Totals for Initial Cost, Current Value, and Gain-Loss. –Percent Gain-Loss comes from Total Gain-Loss / Total Initial Cost. /

13. A.Penjira Kanthawongs13 6. Use the AVERAGE function to determine the average for the # of Shares, Initial Price per share, Initial Stock Cost, Current Stock Price, Current Stock Value, and Gain/Loss for each stock.

14. A.Penjira Kanthawongs14 7. Use the MAX and MIN functions to determine the highest and the lowest values for the # of Shares, Initial Price per share, Initial Stock Cost, Current Stock Price, Current Stock Value, and Gain/Loss for each stock, and Percent Gain/Loss.

15. A.Penjira Kanthawongs15 Web Requirements: Use the Web query feature of Excel to get real-time stock quotes for the stocks owned by BetNet Stock Club (Figure 2-1b)

16. A.Penjira Kanthawongs16 Entering the Titles and Numbers into the Worksheet. To start a new line in a cell, press ALT + ENTER after each line. To start typing in a new cell, press ENTER key or one of the arrow keys. Look in Orange Box on Page E 2.7 about “Wrapping Text.” You can instruct Excel to wrap the text in a cell by Choose the cell you want to change the format | Right-Click | Choose “Format Cells” | Choose “Alignment” tab | Check the box “Wrap Text”.

17. A.Penjira Kanthawongs17 Formatting a Worksheet. Look in all Orange Boxes on Page E 2.8. –You can increase and decrease height if rows to add white space between information. –You may use 4- digit years to ensure that Excel interprets year values the way you intend. –Best way to enter data into a range of cells…Select the range | Enter the data | Press “Enter” key | Enter the data.

18. A.Penjira Kanthawongs18 Important notes when entering dates into Excel. On Page E 2.7, Table 2-1, each Date Acquired is stated by MM/DD/YY. But you need to enter in this format “DD/MM/YYYY” ….always follow this format! Otherwise, you might get wrong calculations at the end. A date should be right-aligned in the cell because it is considered as a number. If you have trouble, try to fix it by Select the date cell | Right-Clicking | Choose “Format Cells” | Choose “Date” | Choose the format you want.

19. A.Penjira Kanthawongs19 This is how the worksheet looks when the titles and numbers are entered before any calculation.

20. A.Penjira Kanthawongs20 Calculations: 1. Initial Cost = Shares x Initial Price 2. Current Value = Shares x Current Price 3. Gain/Loss = Current Value - Initial Cost * * -

21. A.Penjira Kanthawongs21

22. A.Penjira Kanthawongs22 Entering Formulas In Excel, you can start a formula with equal (=), plus (+), and minus (-) signs and they will be considered as numbers and numbers can be calculated! Remember that! If you want to multiply in Excel, you need to press the asterisk (*) not the letter x (X). You can enter the cell references in formulas in uppercase or lowercase, and you can add space before and after arithmetic operators to make the formulas easier to read. –“=d3*e3” is the same as “=D3 * e3”

23. A.Penjira Kanthawongs23 Order of Operations in Excel P 2 Order of Operations or Precedence: 1. First Negation (-3) 2. All percentages (%) 3. All exponentiation s (^) 4. All multiplication (*) and division (/) from Left --> Right 5. All additions (+) and Subtractions (-) from Left --> Right Slash (/) is different from backslash (\)

24. A.Penjira Kanthawongs24 –For example: =6+(-3)^2 | = 6+9 | = 15 =D1 / X6 - A3 * A4 + A5 ^ A6 – ^  /  *  –  +

25. A.Penjira Kanthawongs25 4. Percentage Gain-Loss = Gain-Loss / Initial Cost /

27. A.Penjira Kanthawongs27 Using Point Mode –Point mode allows you to create formulas using the mouse. (Page E 2.11 in Orange Box) Using the Fill Handle –Page E 2.13 –The Fill Handle is a small rectangle in the lower- right corner of the active cell.

28. A.Penjira Kanthawongs28

To see the formulas in the Excel worksheet, click Tools | Options | Choose “View” tab | Check in the box in front of the “Formulas.”

30. A.Penjira Kanthawongs30 5. Compute the Totals for Initial Cost, Current Value, and Gain-Loss. –Percent Gain-Loss comes from Total Gain-Loss / Total Initial Cost. (Page E 2.15) /
