Buying Options: What Investors Should Know

“The greatest ignorance is to reject something you know nothing about.”

If you invest in equity markets or mutual funds, it is useful to understand derivative products such as options. Even if you do not actively trade them, awareness of how options work can help you better understand market movements and investor sentiment.

Over the past few years, options trading has gained popularity. Financial media platforms such as CNBC, NDTV, and ET Now frequently discuss options strategies and derivatives markets.

Many investors are attracted to options because:

• They require lower capital compared to buying stocks

• They offer potentially high returns

• They allow investors to hedge risk

However, options trading also involves significant risks, and investors should fully understand the mechanics before participating.

Types of Options

Options generally come in two main forms:

Call Options

A call option gives the investor the right (but not the obligation) to buy a stock at a predetermined price within a specific time period.

Key characteristics:

• Investors buying call options are bullish on the stock

• The investor is not required to exercise the option

• Options can be held for a few days to several months

If the stock price rises above the strike price, the call option may become profitable.

Put Options

A put option gives the investor the right to sell shares at a predetermined price within a certain period.

Key characteristics:

• Investors buying put options are bearish on the stock

• Put options gain value when stock prices fall

• Observing put activity can sometimes signal growing bearish sentiment in the market

Buying Call Options vs Buying Shares

One of the biggest advantages of buying call options is lower capital requirement.

Let us consider an example using Larsen & Toubro (L&T).

Suppose the stock price is ₹1700, and the lot size in the derivatives market is 125 shares.

Buying Shares

If you want to buy 125 shares:

1700 × 125 = ₹2,12,500

This would be your investment amount.

Buying a Call Option

Instead of buying shares, you could purchase one call option with strike price ₹1700 at a premium of ₹50.

Your total cost would be:

125 × ₹50 = ₹6,250

This means that by investing only ₹6,250, you gain exposure to 125 shares of L&T.

For the option to be profitable at expiry, the stock price must move above:

₹1750 (Strike price ₹1700 + premium ₹50)

If the stock does not rise above this level, the option may expire worthless. In that case, the maximum loss is limited to ₹6,250, which is the premium paid.

Buying Put Options to Protect Your Portfolio

Put options can also be used as a risk management tool.

Buying a put option is often compared to buying insurance for your stock portfolio.

Example

Suppose you already own 125 shares of L&T at ₹1700, and you are sitting on good profits.

However, you are worried that the stock price may fall in the short term, but you do not want to sell your shares.

You could buy a put option with strike price ₹1650 for a premium of ₹50.

If the stock price falls below ₹1650, the put option increases in value and offsets losses in your stock holdings.

If the stock price rises, the option may expire worthless, but your stock investment benefits from the rise.

This strategy is known as a Protective Put Strategy.

Married Put Strategy

Another similar strategy is called the Married Put Strategy.

In this strategy:

• An investor buys shares of a stock

• Simultaneously buys a put option on the same stock

Since both positions are opened together, they are considered “married.”

This strategy allows investors to participate in potential upside while protecting against downside risk.

Advantages of Buying Options

If used correctly, options can offer several advantages:

• Lower capital requirement compared to buying shares

• Limited downside risk (loss limited to premium paid)

• Potential for high percentage returns

• Ability to hedge existing investments

Important Risks to Understand

While options can be powerful financial tools, they are not suitable for all investors.

Some key risks include:

• Options can expire worthless

• Timing plays a critical role

• Market volatility can significantly impact option prices

Many investors lose money simply because they do not fully understand how options behave.

Final Thoughts

Options are an important part of modern financial markets. Even if you are primarily an investor in stocks or mutual funds, understanding the basics of options can help you gain better insights into market behavior.

The purpose of this discussion is to increase awareness about options and their potential uses, not to encourage immediate trading.

Before trading options, investors should always understand the risks, strategies, and implications involved.

In a future discussion, we will also explore options selling strategies and their implications in greater detail.
