Long calls on AI leaders have become expensive. Implied volatility on names like NVIDIA, Broadcom, and ARM tends to spike into earnings and product cycles, and that premium gets baked into every call you buy.
If you are bullish but the outright call premium feels rich, there is a defined-risk alternative that cuts your cost meaningfully: the bull call spread. The trade-off is a cap on your upside.
This article walks through the mechanics, the cost math, and when each strategy actually wins.
Why Long Calls on AI Stocks Are Expensive Right Now
Implied volatility (IV) reflects the market's expectation of future price swings. When IV is high, every option, calls and puts, costs more.
AI leaders carry elevated IV almost continuously. NVDA trades into earnings with options pricing roughly a 6% post-report swing, and AVGO and ARM show similar patterns around their own catalysts.
That is great if you sell premium. It hurts if you are paying it. A 30-day at-the-money call on a high-IV AI stock can easily cost 5-7% of the share price, which means you need a sizeable move just to break even.
Bull Call Spread Mechanics
A bull call spread has two legs in a single trade, same expiration date:
Buy one call at a lower strike (typically at-the-money). Sell one call at a higher strike (out-of-the-money). The premium you collect from the short call offsets part of the cost of the long call.
Your net debit is the long premium minus the short premium. Your maximum loss is that net debit. Your maximum profit is the distance between strikes, minus the net debit. Both outcomes are defined the moment you enter the trade.
According to Fidelity, a bull call spread is established for a net debit and profits as the underlying rises, with both profit and loss capped at known levels (Fidelity options strategy guide).
Cost Reduction Math
Concrete example. Imagine NVDA trades at $200 ahead of a Q2 earnings print, with elevated IV.
A 30-day at-the-money long $200 call might cost around $14 per share, or $1,400 per contract. The same expiration $220 call could trade near $7. If you buy the $200 call and sell the $220 call, your net debit is $14 minus $7, or $7 per share, $700 per contract.
That is a 50% cost reduction versus the outright long call. Your maximum loss drops from $1,400 to $700.
The catch: your maximum profit is now capped at $20 minus $7, or $13 per share ($1,300 per contract). A long call has no upside ceiling. In high-IV environments, spreads typically cut cost 40-60% while capping profit at a defined multiple of the debit.
When to Use a Spread Versus a Long Call
Use a bull call spread when:
Your conviction is directional but bounded. You think NVDA reaches $220 by earnings, not $260. The short call strike is your price target, not a ceiling you fear missing.
IV is elevated. Per Option Alpha, bull call spreads benefit from higher IV at entry because the short leg gets richer relative to the long leg, compressing your net debit (Option Alpha bull call spread guide). Pre-earnings on AI names is a textbook setup.
You want to cap downside. The max loss is the debit paid. No surprises if the trade goes the wrong way.
Stay with a long call when:
You expect an open-ended breakout. If you think AMD could rip 40% on a product cycle, the long call captures all of it. A spread leaves money on the table above the short strike.
IV is low. The cost savings of a spread shrink in low-IV regimes because the short call is not paying you much. Giving up unlimited upside for marginal cost reduction is a poor trade.
Your conviction is high but your target is fuzzy. Long calls are pure directional bets without a target ceiling.
Worked Example: NVDA Pre-Earnings Spread
Suppose NVDA trades at $200 a week before its Q2 FY27 report. IV is elevated, the long $200 call costs $14, and the $220 call costs $7. You buy the $200/$220 bull call spread for a $7 net debit.
If NVDA closes at $225 on expiration, both calls are in-the-money. The spread is worth its maximum value of $20, you net $13 per share ($1,300 per contract), or roughly 186% on the $700 debit.
If NVDA closes at $200 or below, both calls expire worthless and you lose the full $700 debit. Either way, your risk and reward are known from day one. For a deeper look at defined-risk options structures, see Gotrade's options hedging primer.
Conclusion
Bull call spreads are not better than long calls. They are a different trade with a different payoff shape.
If you have a defined price target and IV is rich, the spread cuts your cost and your max loss in exchange for capped upside. If you expect explosive, open-ended moves on AI names, the long call still wins. Pick the structure that matches your conviction.

FAQ
Is a bull call spread always cheaper than a long call?
Yes by construction, because the short call premium offsets part of the long call cost, but the savings vary with IV and strike width.
What happens if the stock closes between the two strikes at expiration?
The long call is in-the-money and the short call expires worthless, so you keep the long call's intrinsic value minus your debit.
Can I close a bull call spread early?
Yes, you can sell the long call and buy back the short call before expiration to lock in gains or cut losses.
Are spreads available on all options-eligible US stocks?
Bull call spreads work on any optionable stock with sufficient liquidity in both strikes, which covers most large-cap AI names.
