Stock trading refers to the buying and selling shares of a particular company; if you own the stock, you own a piece of the company.
Stock traders buy and sell stocks to capitalize on daily price fluctuations. These short-term traders are betting that they can make a few bucks in the next minute, hour, day or month, rather than buying stock in a blue-chip company to hold for years or even decades.
Stocks are the main and only trading instrument in the stock market, which is based on the stock exchange. This type of exchanges is much older than currency exchanges, but is inferior in age to commodity exchanges. The difference between a stock exchange and a currency exchange is that there is no round-the-clock trading on the securities market. Another difference lies in the peculiarities of the price movement. Depending on the performance of a particular corporation, its shares can rise in value by thousands of dollars in a few days, as well as fall. The price movement of various currencies is not so rapid. Only in the event of serious economic shocks, a collapse of the exchange rate occurs, but it still cannot change the value of the currency in the same way as it happens with securities.
