I'm Rich Kleinfeldt with some financial expressions used in business and the stock market.
Our first expression is "in the red." It is another way of saying that a business is losing money. In the
past, numbers in the financial records of a company were written in red ink to show a loss.
A business magazine recently published a report about a television company. The report said the
company was still in the red, but was able to cut its loss from the year before.
A profit by a business is written in black numbers. So a company that is "in the black" is making
money.
Another financial expression is "run on the bank." That is what happens when many people try to
withdraw all their money from a bank. A "run on the bank" usually happens when people believe there
is danger a bank may fail or close.
Newspaper reports about a banking crisis in Russia used that expression.They said the government
acted because of fears that the crisis would cause a run on the banks.
"Day trading" is a system that lets investors trade directly on an electronic market system. It was the
first completely computerized stock market. It sells stocks of companies not listed on any stock exchange. Many high technology companies are listed on it.
Day trading companies provide a desk and a computer system to an investor who wants to trade.
Individuals must provide fifty thousand dollars or more to the trading company to pay for the stocks they
buy. Thousands of other investors do day trading from computers in their homes.
A day trader watches stock prices carefully. When he sees a stock rise in price, he uses the computer
to buy shares of the stock. If the stock continues to rise in price in the next few minutes, the day trader
sells the shares quickly to make a small profit. Then he looks for another stock to buy. If a stock goes
down instead of up, he sells it and accepts the loss.
The idea is to make a small profit many times during the day. Day traders may buy and sell stocks
hundreds of times each day.
