As the premium amounts are equal, the 'contract' is zero cost. At expiry, there are three possibilities:. Companies that regularly utilise options to manage risk tend to be large firms with large financial exposure to floating rates such as interest, FX and commodities. The potential financial losses due to exposure amount will be the primary determinant of justifying the cost of using option derivatives to mitigate risk.
Option premium is the price of an option charged by the writer or sold on an exchange market. Further transaction costs and capital gains taxes may be incurred. Prices can also vary depending on the relationship between buyer company and writer bank and average cost can be reduced by negotiating bundled services from banks.

Arrangements that involve combining both call and put options allow companies to set their own rates in line with their views on rate movements and to suit their financial strategies. The premium the company pays can be offset by the premium the bank pays for the option the company sells. In some circumstances, these premiums cancel each other out and the net cost to the customer is zero.
In Standard option transactions at listed prices, the timeframe is instantaneously online or just a phone call away. In the case of complicated derivatives that require negotiation on pricing tend to take longer and will vary depending on assessing the value of the structured solution and price negotiation between OTC counter parties.
Option expiry dates vary greatly depending on the particular option. They can range from days to years. The flexibility of options allows them to be structured to the needs of the customer.
They take decisions that can benefit the company in the long run. At times, the managers may not be wealthy enough to buy majority of the shares. Therefore, additional funds may have to be raised through debt or with the help private equity funds. So, a large part of the transaction becomes debt financed while the remaining shares are held by private investors.
This debt load on the firm makes its management leaner and more efficient. Definition: Lot size refers to the quantity of an item ordered for delivery on a specific date or manufactured in a single production run. A simple example of lot size is: when we buy a pack of six chocolates, it refers to buying a single lot of chocolate. Description: In the stock market, lot size refers to the number of shares you buy in one transaction. In options trading, lot size represents the total number of contracts contained in one derivative security.
The theory of lot size allows financial markets to regulate price quotes. It basically refers to the size of the trade that you make in the financial market. With the regulation of prices, investors are always aware of exactly how many units they are buying of an individual contract and can easily assess what is the price they are paying for each unit. If no lot size is defined, there will be no standardisation of price and valuing and trading of option contracts would be bulky and consuming.
A smaller lot of production is an important part of many lean manufacturing strategies. Inventory and development directly affect the lot size. There are other factors too, which are less evident but equally essential.

A small lot size causes reduction in variability in the system and ensures smooth production. It enhances quality, simplifies scheduling, reduces inventory, and encourages continuous improvement. In the derivatives market, the lot size of futures and options contracts is determined by the stock exchange from time to time. Related Definitions. Browse Companies:. Mail this Definition.

If the share price is higher than X the call option will be exercised. Else, cash will be retained. If the share price is lower than X, the put option will be exercised.

Else, the underlying asset will be retained. This gives us the put-call parity equation. Equation for put-call parity:. We can summarize the payoffs of both the portfolios under different conditions as shown in the table below. From the above table, we can see that under both scenarios, the payoffs from both the portfolios are equal.

For put-call parity to hold, the following conditions should be met. However, in the real world, they hardly hold true and put-call parity equation may need some modifications accordingly. For the purpose of this blog, we have assumed that these conditions are met. Hence, put-call parity will hold in a frictionless market with the underlying stock paying no dividends.
In options trading, when the put-call parity principle gets violated, traders will try to take advantage of the arbitrage opportunity. An arbitrage trader will go long on the undervalued portfolio and short the overvalued portfolio to make a risk-free profit. Let us now consider an example with some numbers to see how trade can take advantage of arbitrage opportunities.
In this case, the value of portfolio A will be,. Portfolio B is overvalued and hence an arbitrageur can earn by going long on portfolio A and short on portfolio B. The following steps can be followed to earn arbitrage profits. Return from the zero coupon bond after three months will be This stock will be used to cover the short. So far, we have gone through the basic concepts in options trading and looked at an options trading strategy as well.
Options are attractive instruments to trade in because of the higher returns. This way, the holder can restrict his losses and multiply his returns. While it is true that one options contract is for shares, it is thus less risky to pay the premium and not risk the total amount which would have to be used if we had bought the shares instead.
Thus your risk exposure is significantly reduced. However, in reality, options trading is very complex and that is because options pricing models are quite mathematical and complex. So, how can you evaluate if the option is really worth buying? The key requirement in successful options trading strategies involves understanding and implementing options pricing models.
In this section, we will get a brief understanding of Greeks in options which will help in creating and understanding the pricing models. Recall the moneyness concept that we had gone through a few sections ago. For OTM call options, the stock price is below the strike price and for OTM put options; stock price is above the strike price. The price of these options consists entirely of time value. It is based on the time to expiration.

We know what is intrinsic and the time value of an option. We even looked at the moneyness of an option. But how do we know that one option is better than the other, and how to measure the changes in option pricing.

Greeks are the risk measures associated with various positions in options trading. The common ones are delta, gamma, theta and vega. With the change in prices or volatility of the underlying stock, you need to know how your options pricing would be affected. Greeks in options help us understand how the various factors such as prices, time to expiry, volatility affect the options pricing. Delta is dependent on underlying price, time to expiry and volatility. While the formula for calculating delta is on the basis of the Black-Scholes option pricing model, we can write it simply as,.
Here, we should add that since an option derives its value from the underlying stock, the delta option value will be between 0 and 1. While the delta for a call option increases as the price increases, it is the inverse for a put option. Think about it, as the stock price approaches the strike price, the value of the option would decrease. Thus, the delta put option is always ranging between -0 and 1. Gamma measures the exposure of the options delta to the movement of the underlying stock price. Hence, gamma is called the second-order derivative.
Let's see an example of how delta changes with respect to Gamma. In this way, delta and gamma of an option changes with the change in the stock price. We should note that Gamma is the highest for a stock call option when the delta of an option is at the money. Since a slight change in the underlying stock leads to a dramatic increase in the delta. Similarly, the gamma is low for options which are either out of the money or in the money as the delta of stock changes marginally with changes in the stock option.
