Bull Call Spread: The Smart Bull

Mastering Bull Call Spreads on IG Index (UK & Ireland)

Updated over a week ago

Course Description

Why pay full price for a Long Call when you can get a discount? The Bull Call Spread is a professional-grade strategy that uses a "short leg" to subsidize the cost of your "long leg." We will use our US 500 example to show how adding a $7,100 strike can transform your trade's risk-to-reward profile.

Traditional Options vs. Spread Betting

IG’s "options" are actually Spread Bets based on option prices, offering a unique edge for traders in the UK and Ireland.

  • Tax Status: Spread betting is unique to the UK and Ireland. Profits are exempt from Capital Gains Tax (CGT) and Stamp Duty.

  • Trade Unit: Instead of "contracts" (100 shares), you trade in $ per point (or £ per point).

  • The Credit Advantage: Unlike the Bear Put Spread where you pay a debit, here you receive a credit upfront. You are the "house" collecting the premium.

  • Currency: You can trade US markets in GBP or USD to avoid FX conversion fees.

    • Note: While you can fund in Euro, spread bets on options are executed in GBP or USD only.


Module 1: What is a Bull Call Spread?

A Bull Call Spread is a vertical spread where you buy one call and sell another further "Out-of-the-Money" (higher strike).

  • The Goal: Profit from the US 500 rising, but with a lower "breakeven" than a standard call.

  • The Trade-Off: In exchange for a lower cost, you agree to cap your maximum profit at the higher strike price.

  • Why it's smarter: It reduces your "Net Debit" (the money you put at risk) and helps offset the daily cost of time decay.


Module 2: The US 500 Case Study (The Spread)

We are using the same $6,800 long call from the previous Long Call course, but we are now adding a second "leg" to turn it into a spread.

The Setup:

  • Current Market: US 500 @ $6,950

  • Leg 1 (Long): Buy $6,800 Call @ 220.35 pts

  • Leg 2 (Short): Sell $7,100 Call @ 35.70 pts (This is your "Subsidy")

The Math at $5 per point:

  • Net Debit (Cost): 220.35 - 35.70 = 184.65 pts

  • Total Max Risk: 184.65 times$5 = $923.25 vs. $1,101.75 for the long call alone.

  • Maximum Value: 7,100 (Short Strike) - 6,800 (Long Strike) = 300 pts

  • Maximum Profit: (300 - 184.65) times $5 = $576.75

  • Breakeven: $6,800 (Long Strike) + 184.65 (Net Debit) = $6,984.65


Module 3: Probability

By selling the $7,100 call, you have improved your position in two ways:

Lower Breakeven: Your breakeven has dropped from $7,020.35 down to $6,984.65. The market doesn't have to move as far for you to start making money.


Module 4: "What If?" Expiry Scenarios

Let’s see how the spread performs compared to the naked call at the end of the 35 days.

Scenario A: US 500 stays Flat (closes at $6,950)

  • Long 6800 Call: Worth 150 pts.

  • Short 7100 Call: Worth 0 pts (expires worthless).

  • Net Value: 150 pts.

  • Total Result: Loss of $173.25 (150 - 184.65) times $5.

  • Comparison: You lost $178.50 LESS than the Long Call because the short leg protected you.

Scenario B: US 500 drops to $6,800

  • Both calls expire worthless.

  • Total Result: Max Loss of $923.25.

  • Comparison: You saved $178.50 in total losses by using the spread versus the Long Call on its own.

Scenario C: US 500 rises to $7,100+ (The Target)

  • Long 6800 Call: Worth 300 pts.

  • Short 7100 Call: Worth 0 pts.

  • Net Value: 300 pts.

  • Total Result: Profit of $576.75.

  • Comparison with Long Call: While your profit is capped here, you reached your "Max Profit" much faster and with less capital at risk.


Module 5: The "Delta Compass" Workaround

As always, IG Index won't show you the Greeks. For this spread:

  1. Check External Delta: Ensure your Long Leg ($6,800) has a Delta of 0.75+ and your Short Leg ($7,100) has a Delta of around 0.30.

  2. The Goal: You want a "Net Delta" that is positive, meaning you still profit as the market rises, but at a controlled pace.


Strategy Comparison: Risk vs. Probability

Choosing the right strategy depends on your market view and your risk tolerance. At ShareNavigator, we emphasize Probability of Profit (PoP) over "lottery ticket" home runs.

Why Credit Spreads Have a Higher Win Rate

A common question students ask is: "Why not just short the stock or buy a long put if I'm bearish?"

The answer lies in the three directions of the market:

  1. Shorting a Stock / Long Put: You only win if the market moves DOWN. If the market stays flat or goes up, you lose. (1 out of 3 scenarios).

  2. Bear Call Spread: You win if the market moves DOWN, stays FLAT, or even RISES SLIGHTLY (as long as it stays below your ceiling). (3 out of 3 scenarios).

By "selling" time and volatility instead of just betting on direction, you turn the math of the market in your favor.


💡 The ShareNavigator Golden Rule

"We don't try to predict the next 500-point move. We try to identify the 300-point range where the market won't go. Trading is not about being 'right'; it's about not being 'wrong' enough to lose money."

🧪 Practice Before You Trade (Risk-Free)

We strongly recommend that all our students start by practicing these strategies in a simulated environment. This allows you to master the IG deal ticket, understand price fluctuations, and test your "Option Income Engine" without risking a single penny.

Switch to a live account only once you are comfortable with the platform and your strategy execution.
