Understanding Strike Price in Options Trading: A Complete Guide
Introduction
Options trading can be highly rewarding, but to make informed decisions, you need to understand key concepts—one of the most important being the strike price. Whether you are trading for hedging, speculation, or leverage, choosing the right strike price can make all the difference.
In this blog, we will dive deep into what the strike price is, how it works, and how to choose the best one for your options trades.
What is Strike Price?
The strike price (also called the exercise price) is the predetermined price at which an options contract allows you to buy or sell an underlying asset. It plays a crucial role in determining the profitability of your trade.
- For a Call Option, the strike price is the price at which you can buy the asset.
- For a Put Option, the strike price is the price at which you can sell the asset.

How Strike Price Works in Call and Put Options
1️⃣ Call Option Example (Bullish Trade)
Imagine Reliance Industries Ltd. is trading at ₹2,500 per share, and you believe the price will rise.
You buy a Call Option with a strike price of ₹2,600 by paying a premium of ₹50 per share.
✔ If the stock rises to ₹2,700
→ You can buy at ₹2,600 and sell at ₹2,700, making a profit.
❌ If the stock stays below ₹2,600
→ The option expires worthless, and you lose only the premium (₹50 per share).

2️⃣ Put Option Example (Bearish Trade)
Now, imagine you believe TCS (currently at ₹3,500) will fall in price.
You buy a Put Option with a strike price of ₹3,400 by paying a premium of ₹40 per share.
✔ If the stock drops to ₹3,300
→ You can sell at ₹3,400 and buy back at ₹3,300, making a profit.
❌ If the stock stays above ₹3,400
→ The option expires worthless, and you lose only the premium (₹40 per share).

In-the-Money (ITM), At-the-Money (ATM), and Out-of-the-Money (OTM) Options
Strike prices are categorized into three types based on their relationship with the current market price of the underlying asset.
| Type | Call Option Condition | Put Option Condition | Profitability |
|---|---|---|---|
| In-the-Money (ITM) | Strike Price < Market Price | Strike Price > Market Price | Higher Cost, More Likely to Profit |
| At-the-Money (ATM) | Strike Price ≈ Market Price | Strike Price ≈ Market Price | Moderate Cost, Balanced Risk |
| Out-of-the-Money (OTM) | Strike Price > Market Price | Strike Price < Market Price | Cheap, High-Risk but High-Reward |

How to Choose the Right Strike Price?
1️⃣ Consider Market Volatility
- High volatility → Choose ITM or ATM options for better success rates.
- Low volatility → OTM options can be cheaper but riskier.
2️⃣ Your Risk Appetite
- If you prefer safety, ITM options are better.
- If you’re willing to take high risk, OTM options offer bigger potential gains.
3️⃣ Time Until Expiry (Theta Decay Effect)
- If the expiry date is near, ITM options are safer.
- For longer expiries, ATM and OTM options can be considered.
