| Derivatives | : | There are also securities you can trade on the market that derive their price from the parent stocks. There are two types - Options and Warrants - and these are collectively known as Derivatives.
There are two parties involved in an options contract, the writer or seller and the taker or buyer. The writer writes the option and has the obligation of accepting or delivering the stocks. The takers have the right, but not the obligation, to buy or sell the stocks.
There are many advantages of options trading, the least of which is leverage. An option can be bought and sold for a fraction of the stock price, giving an effective higher return (or loss) on investment for a stock price move. | | Warrants | : | Warrants, like options, derive their price from the parent security. Warrants though are issued by banks and other financial institutions and are classified based on whether they have an investment or trading purpose.
Warrants may be issued over securities, a portfolio of securities, a stock price index, currency or commodities. |
