Calendar spreads are a versatile options strategy that allows traders to capitalize on time decay and changes in implied volatility.
This strategy involves selling a short-term option while simultaneously buying a longer-term option at the same strike price, creating a position that benefits from the passing of time and potential volatility shifts.
Calendar spreads are often used when traders expect limited price movement in the short term but anticipate increased volatility or a directional move later on.
They can be structured with calls or puts, making them useful for both bullish and bearish outlooks.
Let’s take a look at Barchart’s Long Call Calendar Screener for May 14th.
I have added a filter for Market Cap above 40b and total call volume above 5,000 to remove small capitalization stocks.
The screener shows some interesting calendar spread trades on popular stocks such as MRVL, CRM, QCOM, SNOW, PDD and NVDA. Let’s walk through a couple of examples.
Marvell Technologies Calendar Spread Example
Let’s use the first line item as an example.
With Marvell Technologies stock trading at $177.95, setting up a calendar spread at $170 gives the trade a neutral to slightly bearish outlook.
Selling the May 29 call option with a strike price of $170 and buying the July 17, $170-strike call will cost around $9.30. That is also the most the trade can lose.
The estimated maximum profit is $1,675, but that could vary depending on changes in implied volatility.
The idea with the trade is that if Marvell Technologies stock remains trades around $170 for the next few days, the sold option will decay faster than the bought option allowing the trade to be closed for a profit.
The breakeven prices for the trade are estimated at around $134 and $234, but these can also change slightly depending on changes in implied volatility.
In terms of trade management if MRVL stock broke through either $134 or $234, I would look to adjust or close the trade.
Note that Marvell Technologies is due to report earnings on May 27th after the closing bell.
Let’s look at another example.
Salesforce Calendar Spread Example
With Salesforce stock trading at $165.84, traders could sell the $170-strike May 29 call and buy the $170-strike July 17 call.
That results in a net cost for the trade of $540 per spread, and that is the most the trade can lose.
The estimated maximum profit is $750, but that could vary depending on changes in implied volatility.
The breakeven prices for the trade are estimated at around $152.50 and $193.50 but these can also change slightly depending on changes in implied volatility.
Note that Marvell Technologies is due to report earnings on May 27th after the closing bell.
Qualcom Calendar Spread Example
The last example we will look at is on Qualcom stock.
With QCOM stock trading at $213.17, traders could sell the $220-strike May 29 call and buy the $220-strike July 17 call.
That results in a net cost for the trade of $1,195 per spread, and that is the most the trade can lose.
The estimated maximum profit is $1,150, but that could vary depending on changes in implied volatility.
The breakeven prices for the trade are estimated at around $195 and $255 but these can also change slightly depending on changes in implied volatility.
Mitigating Risk
Thankfully, calendar spreads are risk defined trades, so they have some build in risk management. Position sizing is crucial to ensure that minimal damage is done if the trade suffers a full loss.
One way to set a stop loss for a calendar spread is close the trade if the loss is 20-30% of the premium paid.
Calendar spreads can also contain early assignment risk, so be mindful of that if the stock breaks through the short strike and it’s getting close to expiry.
Please remember that options are risky, and investors can lose 100% of their investment.
