A put option is an option contract giving the owner the right, but not the obligation, to sell a specified amount of an underlying security at a specified price within a specified time frame. Put-call parity is an important principle in options pricing first identified by Hans Stoll in his paper, The Relation Between Put and Call Prices, in It states that the premium of a call option implies a certain fair price for the corresponding put option having the .

That is, the seller wants the option to become worthless by an increase in the price of the underlying asset above the strike price. Generally, a put option that is purchased is referred to as a long put and a put option that is sold is referred to as a short put. A naked put , also called an uncovered put , is a put option whose writer the seller does not have a position in the underlying stock or other instrument.

This strategy is best used by investors who want to accumulate a position in the underlying stock, but only if the price is low enough. If the buyer fails to exercise the options, then the writer keeps the option premium as a "gift" for playing the game. If the underlying stock's market price is below the option's strike price when expiration arrives, the option owner buyer can exercise the put option, forcing the writer to buy the underlying stock at the strike price.

That allows the exerciser buyer to profit from the difference between the stock's market price and the option's strike price. But if the stock's market price is above the option's strike price at the end of expiration day, the option expires worthless, and the owner's loss is limited to the premium fee paid for it the writer's profit.

The seller's potential loss on a naked put can be substantial. If the stock falls all the way to zero bankruptcy , his loss is equal to the strike price at which he must buy the stock to cover the option minus the premium received. The potential upside is the premium received when selling the option: During the option's lifetime, if the stock moves lower, the option's premium may increase depending on how far the stock falls and how much time passes.

If it does, it becomes more costly to close the position repurchase the put, sold earlier , resulting in a loss. If the stock price completely collapses before the put position is closed, the put writer potentially can face catastrophic loss.

In order to protect the put buyer from default, the put writer is required to post margin. The put buyer does not need to post margin because the buyer would not exercise the option if it had a negative payoff. A buyer thinks the price of a stock will decrease. He pays a premium which he will never get back, unless it is sold before it expires. The buyer has the right to sell the stock at the strike price. The writer receives a premium from the buyer. If the buyer exercises his option, the writer will buy the stock at the strike price.

If the buyer does not exercise his option, the writer's profit is the premium. This is because the underlying stock price is expected to drop by the dividend amount on the ex-dividend date As an alternative to writing covered calls, one can enter a bull call spread for a similar profit potential but with significantly less capital requirement.

In place of holding the underlying stock in the covered call strategy, the alternative Some stocks pay generous dividends every quarter.

You qualify for the dividend if you are holding on the shares before the ex-dividend date To achieve higher returns in the stock market, besides doing more homework on the companies you wish to buy, it is often necessary to take on higher risk.

A most common way to do that is to buy stocks on margin Day trading options can be a successful, profitable strategy but there are a couple of things you need to know before you use start using options for day trading Learn about the put call ratio, the way it is derived and how it can be used as a contrarian indicator Put-call parity is an important principle in options pricing first identified by Hans Stoll in his paper, The Relation Between Put and Call Prices, in With our above argument, we can view this strategy as limited profit with no downside risk but unlimited upside risk.

The pay-off diagram of covered put option is shown in image One lot of put option consists of shares of BOB. Since this is a covered put writing, here Mr. XYZ is short on the underlying i. It is obvious that in the second scenario, the holder will not exercise the option. Here, the payoff would be calculated in two steps. Writing uncovered put or naked put is in contrast to a covered put option strategy.

In this strategy, the seller of the put option does not short the underlying securities. Profit for the writer in this strategy is limited to the premium earned and also there is no upside risk involved since the writer does not short the underlying stocks. However, there is a cushion in the form of premium for the writer.

This premium is adjusted from the loss in case the option is exercised. Looking at the payoffs, we can establish our argument that the maximum loss in uncovered put option strategy is the difference between strike price and stock price with the adjustment of premium received from the holder of the option.
