A long call calendar spread, also known as a call horizontal spread, is an options strategy that involves selling a short-term call option and buying a longer-term call option at the same strike price. This strategy aims to profit from minimal movement in the underlying asset over the short term, benefiting from time decay on the short call, while maintaining the potential for gains if the asset appreciates over the longer term.
Market Outlook: Neutral to slightly bullish in the short term; bullish in the long term.
Risk: Limited to the net premium paid to establish the spread.
Reward Potential: Potentially significant if the underlying asset's price aligns with the strike price at the expiration of the short call, but exact profit is variable.
Time Decay Impact: Time decay benefits the position due to the short call but negatively impacts the long call; the net effect depends on the underlying asset's price movement.
The profitability of a long call calendar spread depends on the relationship between the underlying asset's price and the strike price at the expiration of the short call:
Maximum Profit: Occurs if the stock price equals the strike price at the expiration of the short call, maximizing the time value of the long call.
Maximum Loss: Limited to the net premium paid to establish the spread.
Underlying Asset Price at Initiation: $100
Strike Price for Both Calls: $105
Premium Received for Short (1-month) Call: $2
Premium Paid for Long (3-month) Call: $5
Net Premium Paid (Debit): $3
| Stock Price at Short Call Expiration ($) | Estimated Profit/Loss ($) |
|---|---|
| 95 | -3 |
| 100 | -2 |
| 105 | 1 |
| 110 | -2 |
| 115 | -3 |
Note: The profit/loss values are estimates and can vary based on factors like implied volatility and time decay.
Stock Price at Short Call Expiration: The market price of the underlying asset when the short call option expires.
Profit/Loss: Calculated based on the remaining value of the long call after the short call expires.
Maximum Profit: Occurs if the stock price is at the strike price ($105 in this example) at the expiration of the short call, as the long call retains significant time value while the short call expires worthless.
Breakeven Point: Varies depending on the premiums paid and received; in this example, the breakeven points are approximately at stock prices of $102 and $108 at the expiration of the short call.
Maximum Loss: Limited to the net premium paid ($3 in this example), occurring if the stock price is significantly below or above the strike price at the expiration of the short call, rendering both options worthless or the long call losing substantial value.
At EFIMarkets, we recognize that the long call calendar spread is most effective when the underlying asset is expected to trade within a narrow range near the strike price during the short-term option's lifespan. It's essential to monitor factors like earnings announcements or economic events that could cause significant price movements, as these can impact the strategy's profitability.
Additionally, while this strategy limits potential losses to the initial debit, it also requires careful management, especially as the short-term option nears expiration. Traders should be prepared to adjust or close positions to mitigate risks associated with unexpected market movements.
| Factor | Long Call | Long Call Calendar Spread |
|---|---|---|
| Market Bias | Strongly Bullish | Neutral to Slightly Bullish Short Term, Bullish Long Term |
| Maximum Profit | Unlimited | Limited to time value differences at short call expiration |
| Maximum Loss | 100% of premium paid | Net premium paid (lower than a long call) |
| Time Decay Impact | Negative, as calls lose value over time | Positive if short call expires worthless |
| Implied Volatility Impact | A rise in IV benefits the long call | A rise in IV benefits the long call, but IV drop may hurt |
| Best Used When | Expecting a strong bullish move | Expecting limited short-term movement and a longer-term rise |
For investors seeking similar exposure with different risk profiles, alternative strategies include:
Long Call Option: Involves buying a call option outright, providing unlimited profit potential as the stock price rises, but with a higher upfront cost and the entire premium at risk.
Bull Call Spread: Involves buying a call option at a lower strike price and selling another call option at a higher strike price, both with the same expiration date, to potentially profit from a rising stock price with limited risk.
Diagonal Spread: Involves buying a longer-term call option at a lower strike price and selling a shorter-term call option at a higher strike price, combining elements of vertical and calendar spreads to potentially profit from both time decay and directional movement.
By understanding the mechanics, risks, and profit potential of long call calendar spreads, investors can effectively incorporate this strategy into their portfolios when anticipating neutral to slightly bullish movements in underlying assets over the short term and bullish movements over the long term. However, due to the complexities involving time decay and implied volatility, it's crucial to have a well-thought-out risk management plan and ensure that such positions align with one's risk tolerance and investment objectives.
Note: Options trading involves significant risk and is not suitable for all investors. Before engaging in any options strategies, it's essential to understand the associated risks and consult with a financial advisor.
