In-depth knowledge of F&O Trading

Futures and Options (F&O) trading is a dynamic and sophisticated aspect of financial markets that involves the use of derivative instruments. Derivatives derive their value from an underlying asset, and F&O instruments provide traders with a wide range of opportunities for risk management, speculation, and portfolio diversification. In this article, we discuss the key concepts, strategies, and considerations associated with F&O trading.

Why were Futures and options introduced?

Before we discuss why Futures and Options were introduced in the first place, let us look at the history. The National Stock Exchange (NSE) introduced Nifty F&O in 2000. A year later in 2001, it started stock F&O. If we look at the past two decades' data, the volumes in F&O trading have grown exponentially. Until 2008, the Futures were popular, but after that, it is Options mostly (and we will focus on it).

Let us look at some reasons why F&O trading was introduced:

• Hedging to investors: To give hedging opportunities to investors against price fluctuation in the underlying assets, F&O was introduced. Let us understand it with an example. A farmer might use futures contracts to lock in a price for crops before they are harvested, protecting against the risk of falling prices.
• Making the market more efficient: Futures and Options contribute to the efficient discovery of prices for underlying assets. The continuous buying and selling of derivatives help establish fair market prices based on supply and demand dynamics.
• Investment Opportunities: Traders use derivatives for speculative purposes, aiming to profit from anticipated price movements. Speculation provides liquidity to the market and can lead to more efficient pricing.

Knowledge of option Greeks

You must understand option Greeks if you plan to be an options trader—Delta, Theta, Gamma, and Vega. Option Greeks provide insights into how the option's price is likely to change in response to various factors. These will help you assess and manage risk, make informed decisions, and optimize your strategies. Let us look at all Option Greeks in detail.

Delta: Sensitivity to Price Changes in the Underlying Asset

Delta measures the rate of change in the option's price concerning a one-point change in the underlying asset price. It is expressed as a number between 0 and 1 for call options and between 0 and -1 for put options. A positive delta for calls indicates that the option price will increase with a rise in the underlying asset's price. A negative delta for puts signifies that the option price will decrease as the underlying asset's price rises.

Theta: Time Decay

It measures the rate at which the option's price changes with time. Theta is always negative because options lose value as time progresses. Traders use theta to assess the impact of time decay on their option positions. Theta becomes more pronounced as the option approaches expiration.

Gamma: Rate of Change of Delta

Gamma measures how much the delta of an option changes in response to a one-point move in the underlying asset's price. It is highest for at-the-money options and decreases as options move into the money or out of the money. It is expressed as a positive number. Gamma is crucial for assessing how delta might change, providing insights into the option's exposure to price changes in the underlying asset.

Vega: Sensitivity to Volatility Changes

It measures the impact of changes in implied volatility on the option's price. Vega is expressed in dollars per percentage point change in implied volatility. It is positive for both call and put options. Traders use Vega to assess how sensitive their options positions are to changes in market volatility.

Important terms to know: In the money, out of the money, and at the money strike

These three terms are used in options trading to describe the relationship between the underlying asset's current price and the option strike price. Let us look at them and understand them with examples.

In the Money (ITM): An option is considered 'in the money' when the current price of the underlying asset is favorable for the option holder. An in-the-money option has intrinsic value, which is the difference between the current price and the strike price.

• Call Option (ITM): If the underlying asset's current price is higher than the call option's strike price, the call option is in the money. For example, If the stock is trading at Rs 110 and you hold a call option with a strike price of Rs 100, the call option is in the money by Rs 10.
• Put Option (ITM): If the underlying asset's current price is lower than the put option's strike price, the put option is in the money. If the stock is trading at Rs 90, and you hold a put option with a strike price of Rs 100, the put option is in the money by Rs 10.

Out of the Money (OTM): An option is considered 'out of the money' when the current price of the underlying asset is not favorable for the option holder. Let us look at the Call and Put Option. An out-of-the-money option has no intrinsic value. Its value is entirely composed of time value.

• Call Option (OTM): If the underlying asset's current price is lower than the call option's strike price, the call option is out of the money. If the stock is trading at Rs 90, and you hold a call option with a strike price of Rs 100, the call option is out of the money.
• Put Option (OTM): If the underlying asset's current price is higher than the put option's strike price, the put option is out of the money. If the stock is trading at Rs 110, and you hold a put option with a strike price of Rs 100, the put option is out of the money.

At the Money (ATM): An option is considered 'at the money' when the current price of the underlying asset is very close to the option's strike price. For Call Option, if the stock price is near the call option's strike price, the call option is at the money. For example, if the stock is trading at Rs 100, and you hold a call option with a strike price of Rs 100, the call option is at the money.

Buying vs selling options

Buying and selling options are two distinct strategies with different risk-reward profiles, and traders employ these strategies based on market outlook, risk tolerance, and investment goals. In this section, we will mention the key aspects of buying and selling options.

Buying Options

Call Options: Below are key pointers to keep in mind related to call options:

• Bullish Outlook: Traders buy call options when they anticipate a rise in the underlying asset price.
• Limited Risk: The maximum loss is limited to the premium paid for the call option.
• Unlimited Reward: Profits can be substantial if the underlying asset's price rises significantly.

Put Options: Below are key points to remember about put options:

Bearish Outlook: Traders buy put options when they expect a decline in the underlying asset price.

• Limited Risk: The maximum loss is limited to the premium paid for the put option.
• Unlimited Reward: Profits can be substantial if the underlying asset's price falls significantly.

Selling Options

Here are a few crucial points related to Selling Options:

• Neutral to Slightly Bullish: Traders sell call options against a long stock position to generate income.
• Limited Profit: The maximum profit is capped at the premium received from selling the call option.
• Limited Risk: Risk is partially covered by the long stock position.

Basic option strategies

In the last section, we introduce you to some basic option strategies. Here are four must-know for option traders:

Covered Call: It is a basic options strategy where an investor holds a long position in stocks and sells a call option. It generates income through the premium received from selling the call option, providing some downside protection as the investor already owns the underlying asset. The maximum profit is capped at the strike price of the call, and the strategy is suitable for investors with a neutral to slightly bullish outlook.

Protective Put: The protective put, also known as a married put, involves purchasing a put option alongside a long position in the underlying asset. This strategy is employed to protect against potential downside risk. The put option acts as insurance, allowing the investor to sell the asset at a predetermined strike price, limiting potential losses. While providing downside protection, the cost of the put option reduces the overall profit potential.

Long Straddle: A long straddle is an options strategy where an investor simultaneously purchases a call option and a put option with the same strike price and expiration date. It is employed when you expect a significant price movement in the underlying asset but are uncertain about the direction. Profits are realized if the asset's price moves substantially in either direction, while the risk is limited to the total premium paid for both options.

Long Strangle: Similar to the long straddle, a long strangle involves buying a call option and a put option, but with different strike prices. You may use it when you anticipate a significant price movement but are uncertain about the direction. The goal is to profit from increased volatility. The risk is limited to the total premium paid for both options and the investor profits if the underlying asset's price makes a substantial move in either direction.

Before you go

the introduction of futures and options has added depth and flexibility to financial markets, allowing participants to manage risk, discover prices, and engage in various trading and investment strategies. However, the complexity and leverage involved require traders to approach the market with caution, armed with a solid understanding of the instruments and a disciplined risk management strategy. As with any form of trading, continuous learning and adaptability are key to navigating F&O markets.
