Putting Option Theory Into Practice

Why Case Studies Matter

Options are influenced by several factors at the same time.

The underlying price, volatility, time to expiry and option Greeks can all affect the premium.

Therefore, understanding the theory is only the first step.

The best way to strengthen that understanding is to see how these concepts work together in actual trade situations.

This chapter presents four different examples:

1. A directional Put trade
2. A Delta-neutral volatility trade on a broad market index
3. A Delta-neutral trade around a major company result
4. A directional trade based on fundamental analysis

The original case studies demonstrate how different approaches can be used to build an option position.

Case Study 1 – A Directional Put Trade

Consider a stock trading around ₹1,260.

The stock had been in a strong uptrend, but the recent price movement suggested that the rally might be losing momentum.

The trading range had also started becoming smaller over the previous few sessions.

The trader therefore expected the stock to decline.

Instead of selling the stock directly, the trader chose an OTM Put Option.

The Put was purchased at a premium of approximately ₹45.75, with about one month remaining until expiry.

The Logic Behind the Trade

The basic reasoning was:

Strong rally → Signs of exhaustion → Expect decline → Buy Put

This is a directional trade.

The trader was primarily expressing a view about the direction of the underlying.

The trade therefore depended heavily on the expected price movement happening within the available time.

What Could Go Right?

If the stock falls sharply:

• The Put gains value.
• Delta becomes more favourable.
• The option can move closer to ITM.
• The trader can potentially exit at a profit.

But if the stock remains strong or does not fall sufficiently before expiry:

• Time decay works against the buyer.
• The OTM Put can lose value.
• The premium paid becomes the maximum amount at risk.

Case Study 2 – Trading Volatility Instead of Direction

The second example is different.

Instead of trying to predict whether the market would rise or fall, the trader focused on volatility.

The idea was to create a Delta-neutral position.

A Delta-neutral position attempts to reduce the impact of small movements in the underlying.

The trader was therefore more interested in what would happen to volatility than in predicting the market's direction.

The Event-Based Volatility Idea

Before a major economic or policy announcement, uncertainty can increase.

This can push:

Volatility ↑ → Option Premiums ↑

The trader can therefore consider selling options before the event, expecting volatility to decline after the announcement.

If volatility falls significantly after the event, option premiums can decline.

The position can then potentially be closed at a lower cost.

An Important Warning

This strategy carries risk.

The market can make a very large move after the announcement.

Therefore, a trader cannot assume that falling volatility will automatically compensate for an adverse price movement.

The timing of the trade also matters.

The source specifically points out that such positions are better planned several days before a major event rather than just one day before it.

Why Buying Both Call and Put Is Not Always Enough

Some traders may think:

"The market will definitely move after the announcement, so I will buy both a Call and a Put."

This is known as a Long Straddle.

The logic seems simple:

• If the market rises, the Call should gain.
• If the market falls, the Put should gain.

But there is another factor.

Volatility can fall sharply after the event.

As a result, the losing option may lose value faster than the winning option gains value.

Therefore, the combined position can still lose money even though the market makes a significant move.

Case Study 3 – Trading Around Company Results

The third case study involves a large IT company approaching its quarterly results.

The trader expected the event to increase volatility before the announcement.

The position was therefore established four days before the results, rather than immediately before the event.

The stock was trading close to its ATM Strike, so an ATM Call and ATM Put were used.

At entry:

• Call premium was around ₹48
• Put premium was around ₹47
• Combined premium received was around ₹95
• Call IV was around 40%
• Put IV was around 48%

The position was therefore designed to benefit if volatility declined after the event.

What Happened After the Results?

The company's results were better than expected.

This caused the stock to move upward.

Normally, this would hurt the short Call position.

However, the important factor was the decline in volatility.

After the announcement:

• Call premium increased to ₹55
• Put premium fell sharply to ₹20
• Call IV fell to around 28%
• Put IV fell to around 40%
• Combined premium became ₹75

The trader had initially received ₹95 and later bought back the combined position for ₹75.

That resulted in a 20-point profit per lot.

The Important Lesson

The stock moved in a direction that was unfavourable for one side of the position.

Yet the overall trade made money because the fall in volatility and the movement in the two option premiums worked in the trader's favour.

This demonstrates why option trading cannot be analysed using price direction alone.

Case Study 4 – Fundamental View After Results

The final case study takes a different approach.

Instead of focusing mainly on volatility, the trader used fundamental analysis to form a directional view after the company's results.

The idea was to understand:

• What the results indicated
• Whether the market had already priced in the information
• What the company's future prospects suggested
• Whether an option position could express the expected direction

This shows that options can be used to express a fundamental view, just as they can be used with technical or volatility-based analysis.

The key difference is the reason behind the expected price movement.

Four Trades, Four Different Approaches

The four examples can be simplified as follows:

The important lesson is that there is no single way to trade options.

Different market situations require different approaches.

What These Case Studies Teach

Across all four examples, several concepts from the module come together.

Direction

A trader may have a bullish or bearish view and use Calls or Puts accordingly.

Volatility

A trader may focus on whether volatility is likely to rise or fall.

Delta

Delta helps understand directional exposure and can be used while constructing Delta-neutral positions.

Theta

Time decay affects the value of option positions while they are being held.

Strike Price

The choice of Strike determines the position's sensitivity and potential payoff.

Time to Expiry

The expected move must happen within the available time.

The Bigger Lesson

An option position should never be viewed as simply:

"I think the market will go up."

A better approach is to ask:

• What is my market view?
• How large could the move be?
• How quickly could it happen?
• What is the current volatility?
• Could volatility change?
• How much time is left?
• What will happen to Delta if the underlying moves?
• What is my maximum acceptable risk?

These questions bring together the concepts learned throughout the module.

Practical Insight

The strongest option decisions are usually based on multiple factors working together.

A trader may have the correct directional view but lose money because of time decay or falling volatility.

Similarly, a trader may have a neutral directional view but profit from a decline in volatility.

Therefore, the objective is not merely to predict the market.

It is to understand how the entire option position is likely to behave.

Common Beginner Mistake

A common mistake is treating options like futures and focusing only on whether the underlying price will rise or fall.

Options are different.

The premium can change because of:

• Underlying price
• Time
• Volatility
• Strike
• Greeks

Ignoring these factors can lead to incorrect expectations about the trade.

Key Insight

Successful option trading requires more than a market prediction.

The trader must understand the interaction between price, time, volatility, Strike Price and option Greeks before entering a position.

Key Takeaways

• Options are influenced by multiple factors simultaneously.
• A directional trade primarily depends on the expected movement of the underlying.
• Volatility-based trades focus on changes in implied volatility.
• Delta-neutral positions attempt to reduce directional exposure.
• Major events can cause volatility to rise before the announcement and fall afterwards.
• Buying both Call and Put Options does not automatically guarantee profit from a large market move.
• A fall in volatility can significantly affect option premiums after an event.
• Time to expiry is important in every option trade.
• Strike selection affects the risk and sensitivity of the position.
• Fundamental and technical views can both be used to build directional option trades.
• The most important lesson is to evaluate the entire option position, rather than looking only at the underlying price.
