Stock Purchases and Cost Basis

In recent years, many investors have opened online accounts with brokerage firms, and they buy and sell stocks using a computer.  However, these buy and sell orders are still placed by the brokerage company, and a fee is charged to the investor for this service.  The fee is called a commission.  These online transactions are typically the least expensive way to buy or sell stocks, since a live person is not required to deal with the customer directly in order for the trade to be processed.

Many investors still call their broker via telephone to place a buy or sell order.  Typically, these transactions cost more in commissions, especially if the broker is providing advice on which stocks to buy or sell.  The cost of dealing with a broker in this manner may be many times the amount of an online trade.

Once the investor has either logged on to his or her brokerage account or called  his or her broker, the investor receives information about the current price of a stock.  If the investor considers that the price being quoted for a stock meets his or her own investment goals, then a buy or sell order might be given at that time.

Since the price of a stock often fluctuates, the price quote the investor is given by his or her broker, or the price quote they saw online may not be the same as the price at which the actual transaction occurs.  For instance, the shares of a particular company may be shown at $22.50, but by the time the customer hits the place-order button on his computer, perhaps the price has ticked up to $23.  Perhaps it has dropped to $22.25.  This reflects the auction-like atmosphere of the stock trading floor.  Sometimes, though, these price bumps represent manipulations by shrewd stock players who make money by buying and selling a particular stock many times during the day.

EXAMPLE:
An investor calls his broker and places an order to buy 100 shares of a company.  The price quoted is $40 per share.  the commission charged by this particular broker for this kind of transaction is $50.
          Bought 100 shares at $40 per share= $4,000
          Commission Charged= $50
          Total cost of this block of shares was= $4,050

The cost basis per share is found by dividing $4,050 (total cost) by 100 (number of shares bought).  The cost basis per share on this transaction was $40.50.  Knowing the cost basis per share can be important when large blocks of stock are bought and then sold in smaller blocks over a period of time.

You can see from this example that the price of the stock would need to go up beyond $40.50 for the investor to make money by selling this stock.  Considering that there will be commission charged when they go to sell the stock, the price of this stock would need to be over $41 per share for the investor to make any money, if he pays the same commission fee on the sale of the stock.

Activity

Answer the following questions concerning total cost and cost basis per share.

Group Activity

If you are buying a small number of shares of a relatively inexpensive stock (for example, 20 shares of a $10 stock), how does the commission affect the cost per share differently than buying a large number of shares of a more expensive company?

Why would the cost of commissions be of less worry to a person who only buys or sells stock a few times a year and selects only the stock of companies they plan to keep for a long time?
