✅ Overview
The Bear Put Spread—also called a Bear Put Debit Spread—is an advanced options trading strategy. It is used when a trader expects a moderate decline in the price of an underlying asset. The setup involves buying an In-the-Money (ITM) Put and selling an Out-of-the-Money (OTM) Put with the same expiry.
🧠 Key Features:
- Strategy Type: Bearish
 - Skill Level: Advanced
 - Positions: ITM Put Buy + OTM Put Sell
 - Risk: Limited
 - Reward: Limited
 - Breakeven: Strike Price of Long Put – Net Premium Paid
 
🛠 How It Works
Unlike a Bear Call Spread, the Bear Put Spread involves a net debit because you're paying a higher premium for the long put than what you receive from selling the short put. This results in a capped risk and capped reward.
Traders implement this strategy when they expect the underlying asset to fall slightly to moderately before expiry.
💡 When to Use Bear Put Spread
- When you are moderately bearish on the underlying asset
 - When you want to limit downside risk
 - When you want to reduce the cost of a single long put
 
📊 Real-World Example (NIFTY)
Assume NIFTY is trading at ₹25,400. A trader sets up:
| Order | Option | Strike Price | Action | 
|---|---|---|---|
| Buy | NIFTY18APR25600PE | ₹25,600 | ITM Put (Buy) | 
| Sell | NIFTY18APR25200PE | ₹25,200 | OTM Put (Sell) | 
- Profit: (Strike Difference – Net Premium Paid) × Lot Size
 - Loss: Net Premium Paid
 
If NIFTY rises or stays flat:
Both options expire worthless, resulting in maximum loss, which is the net premium.
📘 Example: Stock at ₹38
Stock trading at ₹38 in June. You anticipate a decline.
| Option | Premium | Action | 
|---|---|---|
| July ₹40 Put | ₹3 | Buy | 
| July ₹35 Put | ₹1 | Sell | 
Lot Size: 100 shares
Net Premium Paid: ₹200
🔍 Scenarios
- Stock stays at ₹38
 
- Long ₹40 Put has ₹2 intrinsic value → ₹200 gain
 - Short ₹35 Put expires worthless
 - Net gain = ₹0 (breakeven)
 
2. Stock rises to ₹42
Both options expire worthless
Maximum loss = ₹200
3. Stock falls to ₹34
Long Put gains ₹600
Short Put loses ₹100
Net Profit = ₹300 → Maximum Profit
🏦 Example: Bank Nifty
| Spot Price | ₹54,900 | 
| Lot Size | 35 | 
| Buy ₹55,100 Put | Premium ₹500 | 
| Sell ₹54,800 Put | Premium ₹400 | 
| Net Premium | ₹100 × 35 = ₹3,500 | 
| Breakeven | ₹55,000 | 
| Max Profit | ₹7,000 | 
| Max Loss | ₹3,500 |
