CALCULATIONS FOR GAIN AND LOSS

The difference between the

TOTAL COST OF PURCHASE

and

TOTAL RECEIVED OF SALE

is

THE GAIN OR LOSS

In order to calculate the total cost of purchase and total received, you need to know:  the number of shares, the purchase price, the sale price, and the broker's fee.

TOTAL COST OF PURCHASE=
(Number of shares X price of stock) + broker's fee

TOTAL RECEIVED OF SALE=
(Number of shares X price of stock) - broker's fee

Broker's Commission:  2% or .02 of purchase and sale
Stockbrokers charge a fee for their services.  This fee is called a commission.  Brokers earn a commission for each transaction (purchase or sale) they execute.  Fees vary, but in The Stock Market Game, it is 2%.

EXAMPLE - CALCULATION FOR
GAIN AND LOSS

The difference between the Total Cost of Purchase and Total Received of Sale is the gain or loss.

For example: 
Maynard Schweeb buys 100 shares of Amnex Inc. for $10.00 and sells them at $15.00.
Total cost of purchase=
(Number of shares X price of stock)  +       broker's fee
             (100 X $10.00)                    +  (100 X $10 X .02)
                     1,000                           +     (1,000 X .02)
                     1,000                           +      $20 = $1,020.00

Total received of sale=
(Number of shares X price of stock)  -       broker's fee
             (100 X $15.00)                    -   (100 X $15 X .02)
                     1,500                           -     $30= $1,470.00

GAIN OR LOSS?  Total received - Total cost
   If number is positive, it is a gain.
   If number is negative, it is a loss.

For example:  Total received of sale - total cost of purchase
   $1,470.00 - $1,020.00 = $450.00 GAIN

Percentage Change in Stock Price

Percentage Change=
The Amount of Change from the Original Price / The Original Price X 100

For Example:

     Case 1
     The change from 42 to 48 is 6.
                      Applying the formula:
                      6 / 42 X 100 = 14.3%

    Case 2
     The change from 3 to 5 is 2.
                      Applying the formula:
                      2 / 3 X 100 = 66.7%

Since the number increased, the percentage change is considered a percentage increase.

Compare Case 1 and 2
Which one increased the most in dollars?
Which one increased the most in true value?

Case 3
What if the stock price went down from 42 to 35?
     The change from 42 to 35 is 7.
           7 / 42 X 100 = 16.7%

Since the number decreased, the percentage change is considered a percentage decrease.
