When to Use a Long Call

  • You are bullish on the underlying stock
  • You want leveraged upside exposure with limited downside
  • You expect a significant move higher before expiration
  • You want to define your maximum risk upfront

Risks

  • Time decay (theta) works against you — the option loses value every day
  • If the stock doesn't move above the break-even by expiration, you lose your entire premium
  • High implied volatility means higher premiums, reducing your potential return

How a Long Call Works


When you buy a call option, you're paying for the right — but not the obligation — to purchase 100 shares of stock at a specific price (the strike price) before a specific date (expiration).


Example

Say AAPL is trading at $195 and you buy the $200 call expiring in 30 days for $4.63 per share ($463 total).


  • If AAPL is at $210 at expiration: Your call is worth $10 (intrinsic value). Your profit is ($10 - $4.63) × 100 = $537.
  • If AAPL is at $200 at expiration: Your call expires worthless. You lose the full $463 premium.
  • If AAPL is at $250 at expiration: Your call is worth $50. Your profit is ($50 - $4.63) × 100 = $4,537.

  • Key Takeaway

    Long calls provide leveraged bullish exposure. You can control 100 shares of stock for a fraction of the cost, but you must be right about both direction and timing.
