Options: A Comprehensive Guide to Understanding and Trading

Introduction to Options

Options (known as 选择权 in Taiwan) are financial derivatives that grant the buyer the right, but not the obligation, to buy or sell an underlying asset at a predetermined price (strike price) by a specific date (expiration date).

Key Terminology:

• Call Option: Gives the holder the right to buy the underlying asset.
• Put Option: Gives the holder the right to sell the underlying asset.
• Premium: The price paid for the option contract.
• Strike Price: The predetermined price at which the asset can be bought/sold.
• Expiration Date: The last day the option can be exercised.

Historical Evolution of Options

Ancient Origins:

• The concept dates back to ancient Greece, where philosopher Thales used an early form of options to profit from olive harvest predictions.
• Biblical references (e.g., Jacob’s labor for Rachel) also reflect期权-like agreements.

Modern Development:

• 17th-century Netherlands: Options emerged during the Tulip Mania, enabling speculative trades on tulip bulbs.
• 1973: The Chicago Board Options Exchange (CBOE) standardized options trading, marking the shift from OTC to centralized markets.
• Asia: Singapore (1986) and Hong Kong (1993) pioneered index options in the region.

Types of Options

1. Vanilla Options:

• Call Options: Bullish bets; profit when the asset’s price rises.
• Put Options: Bearish bets; profit when the asset’s price falls.

2. Exotic Options:

• Barrier Options: Activate/expire if the asset hits a predefined price.
• Binary Options: Fixed payout based on a yes/no outcome (e.g., "Will Asset X reach $Y by date Z?").
• Asian Options: Payout based on the asset’s average price over time.

Pricing and Valuation

Key Factors:

1. Underlying Asset Price: Directly impacts intrinsic value.
2. Strike Price: Higher strike = lower call value (and vice versa for puts).
3. Volatility: Higher volatility increases premium (more potential for profit).
4. Time to Expiry: Longer duration = higher time value.
5. Interest Rates: Higher rates increase call premiums (discounting effect).

Models:

• Black-Scholes: Widely used for European options.
• Monte Carlo Simulation: For complex/exotic options with path-dependent features.

Trading Strategies

Basic Strategies:

• Covered Call: Sell calls on owned assets to generate income.
• Protective Put: Buy puts to hedge against price declines.

Advanced Strategies:

• Straddles: Buy both calls/puts to profit from volatility.
• Butterfly Spreads: Combine multiple options to limit risk/reward.

Risk Management

Approval Levels (U.S. Brokers):
