As economists like to say, there’s no free lunch. Though recently many brokers have been racing to lower or eliminate commissions on trades, and ETFs offer index investing to everyone who can trade with a bare-bones brokerage account, all brokers have to make money from their customers one way or another GSBM.
In most cases, your broker will charge a commission every time that you trade stock, either through buying or selling. Trading fees range from the low end of $2 per trade but can be as high as $10 for some discount brokers. Some brokers charge no trade commissions at all, but they make up for it in other ways. There are no charitable organizations running brokerage services.
Depending on how often you trade, these fees can add up and affect your profitability. Investing in stocks can be very costly if you hop into and out of positions frequently, especially with a small amount of money available to invest.
Remember, a trade is an order to purchase or sell shares in one company. If you want to purchase five different stocks at the same time, this is seen as five separate trades, and you will be charged for each one.
Now, imagine that you decide to buy the stocks of those five companies with your $1,000. To do this, you will incur $50 in trading costs—assuming the fee is $10—which is equivalent to 5% of your $1,000. If you were to fully invest the $1,000, your account would be reduced to $950 after trading costs. This represents a 5% loss before your investments even have a chance to earn.
Should you sell these five stocks, you would once again incur the costs of the trades, which would be another $50. To make the round trip (buying and selling) on these five stocks would cost you $100, or 10% of your initial deposit amount of $1,000. If your investments do not earn enough to cover this, you have lost money by just entering and exiting positions.
