Share trading options give investors the right, but not the obligation, to buy or sell shares at a set price before a certain date. There are two main types: call options (buy) and put options (sell). Traders use options for speculation, income, or hedging risks. Options can amplify gains but also carry high risk, especially if the market moves unfavorably. They are priced based on factors like stock price, strike price, time to expiry, and volatility. While advanced, options offer flexibility and strategic potential for experienced investors. However, beginners should understand the risks and mechanics before engaging in options trading.
