Gamma is used to determine how stable an option s delta is: higher gamma values indicate that delta could change dramatically in response to even small movements in the underlying s is higher for options that are at-the-money and lower for options that are in- and out-of-the-money, and accelerates in magnitude as expiration approaches. Gamma values are generally smaller the further away from the date of expiration options with longer expirations are less sensitive to delta changes. As expiration approaches, gamma values are typically larger, as price changes have more impact on gamma.

A Closing transaction is one that reduces or eliminates an existing position by an appropriate offsetting purchase or sale. This is also known as “squaring off” your position. With respect to an Option transaction:

Traders and investors will buy and sell options for several reasons. Options speculation allows a trader to hold a leveraged position in an asset at a lower cost than buying shares of the asset. Investors will use options to hedge or reduce the risk exposure of their portfolio. In some cases, the option holder can generate income when they buy call options or become an options writer.
These Greeks are second- or third-derivatives of the pricing model and affect things such as the change in delta with a change in volatility and so on. They are increasingly used in options trading strategies as computer software can quickly compute and account for these complex and sometimes esoteric risk factors.
Exchange traded forward commitments are called futures. A future contract is another version of a forward contract, which is exchange-traded and standardized. Unlike forward contracts, future contracts are actively traded in the secondary market, have the backing of the clearinghouse, follow regulations and involve a daily settlement cycle of gains and losses.
Futures are similar to a forward contract. The difference is that futures are standardised agreements to buy or sell an asset in the future at an agreed-upon price. Therefore, they can be traded on stock exchanges.
However, if the market share price is more than the strike price at expiry, the seller of the option must sell the shares to an option buyer at that lower strike price. In other words, the seller must either sell shares from their portfolio holdings or buy the stock at the prevailing market price to sell to the call option buyer. The contract writer incurs a loss. How large of a loss depends on the cost basis of the shares they must use to cover the option order, plus any brokerage order expenses, but less any premium they received.
Warrants are the options which have a maturity period of more than one year and hence, are called long-dated options. These are mostly OTC derivatives.
If the stock rises to $666, your option will be worth $6, since you could exercise the option to acquire the stock for $665 per share and immediately resell it for $666 per share. The profit on the option position would be % since you paid 87 cents and earned $6—that s much higher than the % increase in the underlying stock price from $658 to $666 at the time of expiry.
One of the most appealing elements of options is the flexibility that they offer. When we trade in the cash market there are limitations involved, we can either buy the stock or sell its. But in the options market there are trading strategies based on the prevailing situation and trend in the market.
Rho (p) represents the rate of change between an option s value and a 6% change in the interest rate. This measures sensitivity to the interest rate. For example, assume a call option has a rho of and a price of $. If interest rates rise by 6%, the value of the call option would increase to $, all else being equal. The opposite is true for put options. Rho is greatest for at-the-money options with long times until expiration.
The put writer—the seller—can either hold on to the shares and hope the stock price rises back above the purchase price or sell the shares and take the loss. However, any loss is offset somewhat by the premium received.
A Call Option is said to be ITM when spot price is higher than strike price. A Put Option is said to be ITM when spot price is lower than strike price.
The put option should decrease in value with the increase in the asset price. The put option is the right to sell an asset. Hence, it decreases in value, if the price of the asset increases.
Derivatives take their inspiration from the history of mankind. Agreements and contracts have been used for ages to execute commercial transactions and so is the case with derivatives. Likewise, financial derivatives have also become more important and complex to execute smooth financial transactions. This makes it important to understand the basic characteristics and the type of derivatives available to the players in the financial market.
You, as an Option buyer, pay a relatively small premium for market exposure in relation to the contract value. This is known as Leverage. You can see large percentage gains from comparatively small, favorable percentage moves in the underlying equity. Leverage also has downside implications. If the underlying price does not rise/falls during the lifetime of the Option, Leverage can magnify your percentage loss.
The call option should increase in value with the increase in the asset price. The call option is the right to buy an asset. Hence, it increases in value, if the price of the asset increases.
For options traders, delta also represents the hedge ratio for creating a delta-neutral position. For example if you purchase a standard American call option with a delta, you will need to sell 95 shares of stock to be fully hedged. Net delta for a portfolio of options can also be used to obtain the portfolio s hedge ration.
If the prevailing market share price is at or below the strike price by expiry, the option expires worthlessly for the call buyer. The option seller pockets the premium as their profit. The option is not exercised because the option buyer would not buy the stock at the strike price higher than or equal to the prevailing market price.
