Bull Put Spread Strategy: A comprehensive guide

What is a Bull Put Spread Strategy?

A bull put spread, also known as a short put spread or a credit spread, is like betting on your favourite team not losing. You sell a put option (expecting the stock to stay above a certain level) and buy another put option at a lower price (to cover your losses). This option strategy lets you pocket some money upfront, which is always nice. Plus, time decay and less market panic work in your favor.

Key components of a Bull Put Spread Strategy

• Sell a put option at one strike price.
• Buy another put option at a lower strike price with the same expiration date.

By setting up the spread this way, you create a credit spread, meaning you receive a net premium when entering the trade. Your maximum profit is the credit received, and your maximum loss is limited to the difference between the strike prices minus that credit.

When to use a Bull Put Spread Strategy?

1. Moderately Bullish Market Outlook: Use a bull put spread when you expect the stock price to rise or, at the very least, remain above a certain level. This strategy profits from a steady or mildly bullish market trend, as long as the stock doesn’t drop below the lower strike price.
2. Desire for Limited Risk and Defined Return: If you want to cap both potential losses and gains, a bull put spread is ideal. By selling a higher strike put and buying a lower strike put, you limit your risk while still benefiting from the initial premium received.
3. Advantage of Time Decay: The strategy is suitable when you want time decay to work in your favor. As the options near expiration, if the stock price remains above the short put strike, the options lose value, allowing you to keep more of the premium.

How to set up a bull put spread?

1. Sell a put option at one strike price.
2. Buy another put option at a lower strike price with the same expiration date.

The credit you get is your maximum profit. Your maximum risk is the difference between the strike prices minus the credit received. The closer the strike prices are to the stock price, the more credit you get, but the higher the risk.

Payoff Diagram

The payoff diagram for a bull put spread shows your capped risk and reward. The maximum profit is the credit you received. The maximum loss is the difference between the strike prices minus the credit.

Bull Put Spread Strategy example:

Initial Setup:

• Sell a ₹5,000 put option for ₹200.
• Buy a ₹4,500 put option for ₹50.
• Net Credit Received: ₹200 – ₹50 = ₹150.

Calculations:

• Maximum Profit: Total net credit received = ₹150.
• Maximum Loss: Difference in strike prices – Net credit received = (₹500) – ₹150 = ₹350.
• Break-even Point: Higher strike price – Net credit received per share = ₹5,000 – ₹150 = ₹4,850.

Summary

• Net Credit Received: ₹150.
• Maximum Profit: ₹150.
• Maximum Loss: ₹350.
• Break-even Point: ₹4,850.

This means you profit if the stock stays above ₹5,000, break even at ₹4,850, and incur a loss if it drops below that.

Impact of Time Decay on Bull Put Spread

Time decay, or theta, is your buddy here. As time passes, the value of the options decreases, which is good because you sold the put option. It’s like watching your least favorite soap opera slowly fade away—sweet relief.

• Positive Effect: The option you sold loses value faster than the one you bought.
• Profit Potential: Even if the stock price doesn’t move, time decay can lead to profits.

Impact of Implied Volatility on Bull Put Spread

Bull put spreads benefit if implied volatility drops. Lower volatility means lower option prices. If volatility is high when you enter and drops later, it’s a win for you. Think of it as hoping for calm seas after a storm.

• High Volatility Entry: Sell options when implied volatility is high to receive higher premiums.
• Volatility Decrease: A subsequent drop in volatility reduces option prices, benefiting your position.

Adjusting a Bull Put Spread

If the stock price drops too much, you can adjust the spread. For example, if the stock tanks, you could add a bear call spread above the put spread to create an iron condor. This gives you more credit without adding risk.

Example of a Bull Put Spread adjustment:

Initial Setup:

• Sell a ₹5,000 put option for ₹200.
• Buy a ₹4,500 put option for ₹50.

Adjustment:

• Sell a ₹5,500 call option for ₹150.
• Buy a ₹6,000 call option for ₹50.

Final Iron Condor Setup:

• Sell a ₹5,000 put option for ₹200.
• Buy a ₹4,500 put option for ₹50.
• Sell a ₹5,500 call option for ₹150.
• Buy a ₹6,000 call option for ₹50.

Calculations:

• Breakeven Points: ₹4,750 and ₹5,750.
• Maximum Profit: Total net credit received = ₹150 (initial) + ₹100 (adjustment) = ₹250.
• Maximum Loss: Difference between strike prices – Total net credit = (₹500 – ₹250) = ₹250.

By making this bull put spread adjustment, you increase your potential profit while keeping your risk limited.

Rolling a Bull Put Spread

If the stock hasn’t moved much, you can roll the spread to a later date. Buy back the current spread and sell a new one with a future expiration. This gives you more time and potentially more credit.

• Benefits of Rolling:
  • Extends the time for the trade to become profitable.
  • Allows adjustment of strike prices based on new market expectations.
  • Potentially collects additional premium.

Advantages of the Bull Put Spread Strategy

• Limited Risk: Your maximum loss is capped.
• Income Generation: Receive premium upfront.
• Profit from Time Decay: Time works in your favor.
• Flexibility: Can adjust or roll the position as needed.
• Benefit from Decreased Volatility: Lower implied volatility can enhance profits.

Disadvantages of the Bull Put Spread Strategy

• Limited Profit Potential: Maximum gain is limited to the credit received.
• Requires Correct Market Outlook: Stock must stay above the higher strike price.
• Potential for Loss: If the stock price drops significantly, you could incur a loss up to the maximum loss.

Tips for implementing the Bull Put Spread

• Analyse Market Trends: Ensure a bullish or neutral outlook on the underlying asset.
• Monitor Volatility Levels: Enter when implied volatility is relatively high.
• Select Appropriate Strike Prices: Balance between risk and reward.
• Manage Risk: Be prepared to adjust or exit the position if the market moves against you.

Frequently Asked Questions

What happens if both options expire In-The-Money?

If both options expire in-the-money, you’ll be assigned on the short put and will have to buy the stock at the higher strike price. Simultaneously, you’ll exercise your long put to sell the stock at the lower strike price. The net result is a loss equal to the maximum loss of the spread.

Can i close the position before Expiration?

Yes, you can close both options before expiration to lock in profits or limit losses. This is often done if the spread has achieved most of its potential profit before expiration or if market conditions change unfavorably.

Is the Bull Put Spread suitable for beginners?

While it involves more complexity than simply buying a stock, the bull put spread strategy’s limited risk and reward make it a manageable strategy for those familiar with options trading basics.
