The concept of leverage is used by both investors and companies. Investors use leverage to significantly increase the returns that can be provided on an investment. They lever their investments by using various instruments that include options, futures and margin accounts. Companies can use leverage to finance their assets. In other words, instead of issuing stock to raise capital, companies can use debt financing to invest in business operations in an attempt to increase shareholder value.
Currencies are traded on the Foreign Exchange market, also known as Forex. This is a decentralized market that spans the globe and is considered the largest by trading volume and the most liquid worldwide. Exchange rates fluctuate continuously due to the ever changing market forces of supply and demand. Forex traders buy a currency pair if they think the exchange rate will rise and sell it if they think the opposite will happen. The Forex market remains open around the world for 24 hours a day with the exception of weekends.
