Stocks vs. Securities: Understanding the Rights You Own
Stocks are securities that represent ownership in a company. Learn how their rights differ from bonds and funds, and why products traded in the same app need different analysis.
A stock is a security representing an ownership interest in a company, while securities is a broader term. Even if prices on a trading screen appear to move in similar ways, first establish whether you hold an equity interest or a debt claim.
Returns come from different rights
Common shareholders participate in the value of a company's residual profits and assets as it grows. Dividends depend on company decisions and financial conditions, unlike a contract paying fixed interest. A bond involves lending money to an issuer and having a claim to the agreed interest and principal payments. Bonds can also incur losses if the issuer loses its ability to pay, and their market prices fluctuate if sold before maturity. A falling stock price does not give shareholders a right to get their principal back.
Separate where a product trades from what it is
Trading a product through a securities account does not make it an ownership interest in a business. Buying units in a fund that holds multiple assets involves a different investment structure from becoming a direct shareholder in an individual company. First record whether the product is a stock, bond, or fund, along with its issuer. Then check whether it has a maturity date, who is obligated to make cash payments, and the ranking of your claim if the company runs into trouble. These questions can reveal risks that a price chart alone easily misses.
Match your company analysis to the rights you hold
For stocks, important questions include growth in residual earnings and changes in the number of shares. For bonds issued by the same company, cash available to service principal and interest, debt maturities, and collateral terms are more direct concerns. A growing company may dilute existing shareholders through excessive new share issuance, while a slower-growing company may still have ample cash to repay its debts. The U.S. regulatory materials below explain the basic concepts of these rights; check the relevant offering terms and prospectus separately for the detailed legal rights of Korean products. If a security's name is unfamiliar, write one sentence describing when it pays you cash and another describing when it can produce a loss. For example, distinguish a product that gives you a claim to a specified annual payment from one that pays cash only if the company declares a dividend. If you cannot verify those sentences in the prospectus, you do not yet have a sufficient foundation for analyzing price movements. The issuer's business prospects and the return structure of your contract are connected, but they are distinct.
Worked example
Hypothetical example: Suppose you hold KRW 1 million of a company's stock and KRW 1 million of its bonds. Even if the company's profits double, the bond's contractual interest rate does not automatically double. Conversely, the stock may pay no dividend at all. Writing out the expected cash flows of both products shows why equal investment amounts do not mean equal rights.
What to check
- Have you checked the product's issuer and legal form?
- Does it have a maturity date and payment obligations?
- Have you distinguished equity ownership from the issuer's ability to repay its bonds?
