A put option is a financial contract that gives the holder the right, but not obligation, to sell an asset at a predetermined price (strike price) within a specific timeframe. This tool is commonly used for hedging against market downturns or speculating on falling prices.

Key Features of Put Options:

  • Strike Price: The guaranteed selling price
  • Expiration Date: Deadline to exercise the option
  • Premium: Cost paid to purchase the option
  • Intrinsic Value: Difference between strike price and market price

How Put Options Work:

  • Value increases as underlying asset price decreases
  • Commonly used for portfolio protection
  • Can be traded through specialized brokers
  • Time decay reduces option value as expiration approaches

Example: If you buy a put option with a $50 strike price when a stock trades at $50, and the stock falls to $40, you can:

  • Exercise the option to sell at $50
  • Sell the option for a profit
  • Let it expire if the stock price rises above $50

Risk Considerations:

  • Maximum loss limited to premium paid (for buyers)
  • Maximum profit is strike price minus premium (if stock goes to zero)
  • Time decay works against option buyers
  • Writing puts carries potentially significant risk

Trading Strategy: Most traders sell valuable options rather than exercise them because:

  • Captures remaining time value
  • Reduces transaction costs
  • Avoids additional margin requirements
  • Provides more immediate liquidity

Put options are essential tools for risk management and speculative trading, but require careful consideration of market conditions, timing, and risk tolerance.
