    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.

    Defined risk
    Max loss = spread width - credit received
    Lower capital requirement
    Only collateral for the spread width, not full strike
    How the spread works:
    Sell put at higher strike (collect premium)
    Buy put at lower strike (pay premium)

    What Each Metric Means

    1

    Days to Expiration (DTE)

    32 days

    Both 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.

    2

    Strike Prices

    $250 / $245

    The spread consists of two puts with different strikes:

    Short Put: $250
    You sell this put and collect $5.85 premium
    Long Put: $245
    You buy this put and pay $4.25 premium

    The $5 width between strikes defines your maximum risk. The long put protects you if AAPL drops significantly below your short strike.

    3

    Net Credit

    $1.60 per share

    The 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.

    This is your maximum profit. If AAPL stays above $250 at expiration, both puts expire worthless and you keep the full $160.
    4

    Gain/Loss Profile

    $160 / -$340

    Unlike a naked put, your risk is defined and capped:

    Spread Width:$5.00 × 100 = $500
    Net Credit Received:- $160
    Maximum Loss:$340

    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.

    5

    Return on Risk (RoR)

    47.1%

    Return on Risk shows your potential profit relative to the capital at risk:

    Max Gain / Max Loss = $160 / $340 = 47.1%

    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.

    Note the trade-off: This spread has a lower POP (76%) than a typical CSP because we're selling closer to the money for higher premium. The 47% return on risk compensates for this.
    7

    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%.

    How it's calculated:
    Return on Risk: 47.1%
    Days in trade: 32
    Annualized: 47.1% × (365/32) = 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.

    8

    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."

    More cushion
    Higher POP, lower premium
    Less cushion
    Lower POP, higher premium

    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.

    9

    P&L Profile & Breakeven

    $248.40

    The breakeven is calculated as: Short Strike - Net Credit = $250 - $1.60 = $248.40

    AAPL above $250 at expiration
    Both puts expire worthless → Keep full $160 credit
    AAPL between $245 and $250
    Partial loss → Depends on exact price
    AAPL below $245 at expiration
    Maximum loss → Lose $340 (capped by long put)

    382
    Profitable
    AAPL stayed above breakeven
    122
    Unprofitable
    AAPL fell below breakeven
    Expected Return: $38 — This factors in both winning and losing scenarios. On average, you'd expect to make $38 per trade based on historical data.

    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
    When to use a Bull Put Spread: When you're bullish but want defined risk, when you have limited capital, or when you want to trade more positions with the same account size.
