A Long Call Calendar Spread is initiated by selling one call option and simultaneously buying a second call option of the same strike price of underlying assets with a different expiry. It is also known as Time Spread or Horizontal Spread. The purpose of this strategy is to gain from Theta with limited risk, as the Time Decay of the near period expiry will be faster as compared to the far period expiry. As the near period option expires, far month call option would still have some premium in it, so the option trader can either own the far period call or square off both the positions at same time on near period expiry.

When to initiate a Long Call Calendar Spread?

A Long Call Calendar Spread can be initiated when you are very confident that the security will remain neutral or bearish in near period and bullish in longer period expiry. This strategy can also be used by advanced traders to make quick returns when the near period implied volatility goes abnormally high as compared to the far period expiry and is expected to cool down. After buying a Long Calendar Spread, the idea is to wait for the implied volatility of near period expiry to drop. Inversely, this strategy can lead to losses in case the implied volatility of near period expiry contract rises even if the stock price remains at same level.

How to construct a Long Call Calendar Spread?

A Long Call Calendar Spread is implemented by selling near month at-the-money/out-the-money call option and simultaneously buying far month at-the-money/out-the-money call option of the same underlying assets.

Strategy

Buy far month ATM/OTM call and sell near month ATM/OTM call.

Market Outlook

Neutral to positive movement.

Motive

Hopes to reduce the cost of buying far month call option.

Risk

Limited to the difference between the premiums.

Reward

Limited if both the positions squared off at near period expiry. Unlimited if far period call option hold till next expiry.

Margin required

Yes

Let’s try to understand with an example:

Nifty Current spot price

9000

Sell near month ATM call strike price Rs.

9000

Premium received (per share) Rs.

180

Buy far month ATM call strike price Rs.

9000

Premium paid (per share) Rs.

250

Lot size (in units)

75

Suppose Nifty is trading at 8800. An investor, Mr. A is expecting no significant movement in near month contract, so he enters a Long Call Calendar Spread by selling near month strike price of 9000 call at Rs.180 and bought 9000 call for Rs.250. The net upfront premium paid to initiate this trade is Rs.70, which is also the maximum possible loss. The idea is to wait for near month call option to expire worthless by squaring off both the positions in near month expiry contract or reduce the cost of far month buy call by setting off the profit made from the near month call option. Another way by which this strategy can be profitable is when the implied volatility of the near month falls.

For the ease of understanding, we did not take into account commission charges. Following is the payoff chart of the expiry.

Following is the payoff schedule till far expiry, where maximum loss would be limited up to 320 Rs (250+70), Rs 70 is from near expiry and Rs 250 is the premium of far month call bought. Maximum profit would be unlimited since far month call bought will have unlimited upside potential.

The Payoff Graph

Impact of option Greeks:

Delta: The net Delta of a Long Call Calendar will be close to zero or marginally positive. The negative Delta of the near month short call option will be offset by positive Delta of the far month long call option.

Vega: A Long Call Calendar has a positive Vega. Therefore, one should buy spreads when the volatility of far period expiry contract is expected to rise.

Theta: With the passage of time, if other factors remain same, Theta will have a positive impact on the Long Call Calendar Spread in near period contract, because option premium will erode as the near period expiration dates draws nearer.

Gamma: Gamma estimates how much the Delta of a position changes as the stock prices changes. The near month option has a higher Gamma. Gamma of the Long Call Calendar Spread position will be negative till near period expiry, as we are short on near period options and any major upside movement till near period expiry will affect the profitability of the spreads.

How to manage risk?

A Long Call Calendar spread is exposed to limited risk up to the difference between the premiums, so carrying overnight position is advisable but one can keep stop loss on the underlying assets to further limit losses.

Analysis of Long Call Calendar Spread strategy

A Long Call Calendar Spread is the combination of short call and long call option with different expiry. It mainly profits from Theta i.e. Time Decay factor of near period expiry, if the price of the security remains relatively stable in near period. Once the near period option has expired, the strategy becomes simply long call, whose profit potential is unlimited.

    This article claims RJio was given a "Backdoor Entry" into the 4G Based Voice Routing. The peculiar aspect is without the Voice License, Rjio would have been a mere ISP. With the license, it is now a holistic communications service provider, with ability to exponentially scale the bouquet of products. The events indicate it was meticulously planned way before the auctions because the auctions were clear on the agenda: 4G for internet only.

Why to Choose Mutual Funds Instead of Directly Investing Into Equities?

Whether to invest in equities or mutual funds is a question that has plagued every investor. As someone who needs the best value for his/her investment should you invest in equity directly or via mutual funds?

Let’s start by first understanding what these two terms ‘equities’ and ‘mutual funds’ stand for-

Equities- Equities generally represent ownership of a company. If you own any equity in a company, you are a part owner of the said company (depending on how much equity you own).

Mutual Funds – It is an investment scheme which is professionally managed by an asset management company. It pools together the resources of a group of people and invests their money in equities, debentures, bonds and other securities.

Why choose mutual funds over equities?

For people who’ve never invested in either stocks or mutual funds, it is hard to know which is better and where to start. Broadly speaking, if you are a novice investor, mutual funds are not only less risky but also way easier to manage. Here are some ways in which investing in mutual funds is beneficial as opposed to investing in equities -

Diversification

Mutual funds provide more diversification as compared to an individual equity stock. When you invest in equity, you are investing in a single company which has its inherent risk. For example, if you invest Rs.20,000 in buying equities of one company, you could face a total loss if that particular company performs poorly in the market.  

If you invest the same amount in mutual funds, it will be invested in different kinds of stocks and financial instruments, high-risk and low-risk both, so you might not face total loss even if one company does poorly.

Scale of Investment and Lower Costs

For an individual investor buying and selling stocks is a difficult task due to its high price. Thus, any gains made from stock appreciation are nullified if the overall trading costs are considered. Comparatively with mutual funds, as the money is pooled from a large number of investors, the cost per individual is lowered.  

Another advantage of mutual funds is that you don’t need to invest large sums of money. Buying equities for a profitable venture needs huge amounts of money, a minimum of few lakhs. With mutual funds, you can start with Rs.1000 and earn profits on that as well.

Convenience

Keeping an eye on the markets everyday is a time-consuming business, especially if you are investing as a side gig. There are people who spend their lives studying the market and still end up sustaining heavy losses. Though investing in mutual funds does not guarantee high returns, it is stress-free and needs less work as compared to investing in equities.

To sum it up

It is important to remember that mutual funds have their own disadvantages as well. Thus, as with any financial decision, educating yourself and understanding the suitability of all the available options is the ideal way to invest.
