Strike Price Explained
Learn what strike price means in options, how it affects moneyness, premium, breakeven, and risk.
The strike price is the fixed price at which the option can be exercised. It is central to moneyness, payoff, and premium.
Before risking money
Know the max loss and the dollar amount after the 100-share multiplier.
Paper trade the exact contract and record bid, ask, midpoint, IV, and Greeks.
Avoid contracts with wide spreads, stale quotes, or thin open interest.
Understand expiration and what happens if you hold too long; short-option positions add assignment risk.
Lesson
Plain-language concept
For a call, lower strikes are usually more expensive because they already have more upside claim. For a put, higher strikes are usually more expensive because they protect more downside.
Lesson
What can go wrong
Beginners often pick far out-of-the-money strikes because they are cheap. Cheap contracts can have low probability, wide spreads, and rapid time decay.
Lesson
When to use CuteMarkets data
Use chain data to compare premiums, Greeks, and spreads across strikes instead of picking the cheapest row.
Numeric example
Strike comparison
Setup
- Stock price: $100
- $95 call premium: $7.00
- $105 call premium: $2.00
Outcome
- $95 call has $5 intrinsic value immediately.
- $105 call needs the stock to move above $105 before intrinsic value begins.
Different strikes are different risk profiles, not just different prices.

FAQ
Common beginner questions
Is a lower strike always better for calls?
No. It costs more and changes risk, capital, and percentage return profile.
Why are far strikes cheap?
They are less likely to finish in the money and may have little intrinsic value.
How does strike affect delta?
Near-the-money options usually have deltas closer to 0.50 for calls or -0.50 for puts.
