Bear Put Spread

🔍 What Is a Bear Put Spread?

A bear put spread (also called a “vertical bear put spread”) involves two simultaneous transactions on the same stock, with the same expiration date:

You buy a put option at a higher strike price (this is your “long” leg).
You sell a put option at a lower strike price (this is your “short” leg).

By selling the lower-strike put, you collect a premium that offsets the cost of buying the higher-strike put. This drastically reduces your net out-of-pocket cost. However, in exchange for that cheaper entry price, you agree to cap your maximum profit if the stock crashes through the floor.

📊 How It Works (Step-by-Step Example)

Let’s say Stock XYZ is currently trading at $100. You are bearish and think the stock is going to drop, but you don’t think it will go completely bankrupt.

Buy the $100 strike put for $5.00 ($500 total).
Sell the $90 strike put for $2.00 ($200 total).
Net Cost (Max Risk): $5.00 – $2.00 = $3.00 ($300 total).

Here is your financial picture for this trade:

Maximum Risk (Loss): The net premium you paid, which is $3.00 ($300). You lose this if the stock stays above $100 at expiration.
Maximum Profit: The difference between the strikes minus the net premium you paid: ($100 – $90) – $3.00 = $7.00 ($700 per contract). This is your max profit if the stock drops to or below $90.
Breakeven Point: Higher strike price – net premium paid: $100 – $3.00 = $97. The stock must close below $97 for you to make a profit.

📈 The Two Scenarios at Expiration

Here is exactly what happens when the options expire:

Scenario A (Bullish/Bearish Fail): Stock closes at $105.
Both puts expire worthless. You lose your entire $300 net investment.
Scenario B (Moderately Bearish): Stock drops to $95.
Your $100 put is worth $5.00 ($500). Your $90 put is worthless ($0). After subtracting your original $300 cost, your net profit is $200.
Scenario C (Very Bearish): Stock crashes to $80.
Your $100 put is worth $20. Your $90 put is worth $10. Because you sold the $90 put, you are obligated to buy shares at $90 if exercised, but you have the right to sell them at $100. Your intrinsic gain is $10 ($1,000). After subtracting your $300 cost, your max profit is $700. Even if the stock goes to $0, you still only make $700.

✅ Why Use a Bear Put Spread?

Cheaper Than a Plain Long Put: Buying a straight $100 put costs $500. By selling the $90 put, you reduce your cost to just $300. It lowers your financial risk.
Better Breakeven Point: A plain $100 long put has a breakeven of $95 ($100 – $5). The bear put spread has a breakeven of $97. This means the stock doesn’t have to drop as far for you to start making a profit compared to the plain long put!
Less Time-Decay Pain: The short put you sold (the $90 strike) helps offset the “theta decay” (time erosion) that eats away at long options. If the stock drifts sideways, your losses accumulate slower than a standard long put.

⚠️ The Trade-Offs and Risks

Capped Downside Profit: This is the biggest drawback. If the company goes bankrupt and drops to $0, you cannot make unlimited profits. You capped your max gain at $7.00 per share. A plain long put would have made a killing at $0.
Max Loss is Still 100%: While your dollar loss is smaller than a long put, you can still lose 100% of your net investment ($300) if the stock doesn’t move.
Early Assignment Risk (Rare): If the stock drops deep into the money and has little time left, the buyer of the put you sold (the $90 strike) might exercise early, forcing you to buy shares at $90. This can complicate your margin requirements.

🆚 Bear Put Spread vs. A Standard Long Put

Feature	Long Put	Bear Put Spread
Cost	High (pays full premium)	Low (premium is offset by selling a lower put)
Max Loss	Full premium paid	Full net premium paid (cheaper)
Max Profit	Potential large	Strictly capped (limited by the lower strike)
Breakeven	Strike – Full Premium	Strike – Net Premium. Easier to hit
Best For	Expecting a catastrophic crash (e.g., 30%+ drop)	Expecting a steady, moderate drop (e.g., 5%–15%)

💡 Pro Tips for Trading Bear Put Spreads

Sell at Resistance: The absolute best time to enter a bear put spread is when a stock rallies up to a strong resistance level (like a 200-day moving average) and shows signs of reversing. You are betting the rally fails.
Choose Strike Widths Wisely: Wider spreads (e.g., $10 apart vs. $5 apart) cost more but offer higher max profits. Narrower spreads are cheaper but require the stock to drop precisely within a tight range.
Don’t Fight the Trend: Bear put spreads are directional bets. Only use them in a clear downtrend or when a stock has specific negative catalysts (like bad earnings or a broken growth story). Trying to short a stock in a raging bull market is a recipe for losing your premium.
Take Profits Early: Because time decay works against you, if the stock drops sharply in the first week and your spread is up 50%, close the trade. The remaining time might erode those gains. Locking in a 50% profit in a few days is a massive win.
