Securities refer to financial instruments that represent ownership or debt in a company or government entity. These instruments are typically traded in financial markets and can include stocks, bonds, options, and derivatives. Securities provide investors with a way to invest their money and earn a return based on the performance of the underlying asset or entity. They can be bought and sold on exchanges or through over-the-counter markets. Securities are regulated by government agencies to ensure transparency and protect investors from fraud or manipulation. Overall, securities play a crucial role in the global economy by facilitating capital formation and enabling individuals and institutions to invest and grow their wealth.
