Understanding Vertical Spread Results
Let's walk through a bull put spread screener result step by step. We'll use Apple (AAPL) with a Balanced risk profile to explain the key metrics for this defined-risk strategy.
What is a Bull Put Spread?
A bull put spread (also called a "put credit spread") is a defined-risk, bullish strategy where you sell a put at a higher strike and buy a put at a lower strike. You collect a net credit and your maximum loss is capped by the long put.
The Setup

Below is the actual output from the bull put spread screener. We've numbered the key metrics so you can reference the explanations that follow.

What Each Metric Means
Days to Expiration (DTE)
32 daysBoth legs of the spread expire on February 27, 2026, which is 32 days away. The Balanced profile targets 21-45 DTE for vertical spreads.
Why this timeframe: Provides good theta decay while allowing enough time for the trade to work. Shorter DTE has faster decay but less margin for error.
Strike Prices
$250 / $245The spread consists of two puts with different strikes:
The $5 width between strikes defines your maximum risk. The long put protects you if AAPL drops significantly below your short strike.
Net Credit
$1.60 per shareThe net credit is the difference between the premium you collect (short put) and the premium you pay (long put): $5.85 - $4.25 = $1.60 per share, or $160 per contract.
Gain/Loss Profile
$160 / -$340Unlike a naked put, your risk is defined and capped:
No matter how far AAPL falls, you can never lose more than $340 per spread. This is the key advantage of vertical spreads over selling naked options.
Return on Risk (RoR)
47.1%Return on Risk shows your potential profit relative to the capital at risk:
This means for every dollar you risk, you could make 47 cents. This is a key metric for comparing different spread opportunities.
Probability of Profit (POP)
76%Based on 2 years of historical data, there's a 76% probability that AAPL would have stayed above the breakeven price ($248.40) over similar 32-day periods.
Annualized Return on Risk
536.8%If you could repeat this exact trade throughout the year with similar results, your annualized return would be approximately 536.8%.
This high number reflects the efficiency of defined-risk spreads. You're using $340 in collateral instead of $25,000+ for a cash-secured put at similar strikes.
Current Price & Distance to Short
$255.09 / 2.0%AAPL is currently trading at $255.09, which is 2.0% above your short strike of $250. This is called the "cushion" or "distance to short strike."
A 2% cushion is relatively tight, which is why this spread offers attractive premium but moderate POP. More conservative traders might prefer 5-10% cushion.
P&L Profile & Breakeven
$248.40The breakeven is calculated as: Short Strike - Net Credit = $250 - $1.60 = $248.40
Backtest Analysis
504 data pointsThe screener analyzed 504 historical scenarios (approximately 2 years of trading days) to determine how often a similar spread setup would have been profitable.
Bull Put Spread vs Cash-Secured Put
Bull Put Spread
- Defined risk — max loss is capped
- Lower capital — only $340 collateral vs $25,000+
- Higher leverage — better capital efficiency
- Lower absolute profit potential
Cash-Secured Put
- Higher premium — keep full premium collected
- Stock acquisition — get shares if assigned
- High capital — need full strike × 100
- Undefined risk — stock could go to zero
Trade Summary
What You're Agreeing To

- 2Receive $160 net credit immediately
- 3If AAPL stays above $250: keep full $160
