Stocks represent ownership in a company, while bonds are a type of security that represent a loan made to a company or government. There are several types of securities that can be bought and sold in the stock market, including common stocks, preferred stocks, warrants, Philippine Deposit Receipts (PDRs), and Small-Denominated Treasury Bonds (SDT-Bonds). In the Philippines, the main stock exchange is the Philippine Stock Exchange (PSE). Investors can profit from capital gains if a stock price rises, from cash or stock dividends, stock rights offerings, or other means.
