Forecasting Market Direction With Put/Call Ratios

The term "put-call" parity refers to a principle that defines the relationship between the price of European put and call options of the same class.

Put simply, this concept highlights the consistencies of these same classes. Put and call options must have the same underlying assetstrike priceand expiration date in order to be in the same class. The put-call parity, which only applies to European options, can be determined by a set equation.

As noted above, the put-call parity is a concept that applies to European options. These options are of the same class, meaning they have the underlying asset, strike price, and expiration date. As such, the principle put call ratio investopedia apply to American optionswhich can be exercised at any time before the expiration date. Put-call parity states that simultaneously holding a short European put and long European call of the same class will deliver the same return as holding one forward contract on the same underlying asset, with the same expiration, and a put call ratio investopedia price equal to the option's strike price.

If the prices put call ratio investopedia the put and call options diverge so that this relationship does not hold, an arbitrage opportunity exists.

This means that sophisticated traders can theoretically earn a risk-free profit. Such opportunities are uncommon and short-lived in liquid markets. The equation that expresses put-call parity is:. The put-call parity concept was introduced by economist Hans R. Stoll in his December paper "The Relationship Between Put and Call Option Prices," which was published in The Journal of Finance. When one side of the put-call parity equation is greater than the other, this represents an arbitrage opportunity.

You can sell the more expensive side of the equation and buy the cheaper side to make, put call ratio investopedia, for all intents and purposes, a risk-free profit. In practice, this means selling a put, shorting the stock, buying a call, put call ratio investopedia, and buying the risk-free asset TIPSfor example.

In reality, opportunities for arbitrage are short-lived and difficult to find. In addition, the margins they offer may be so thin that an enormous amount of capital is required to take advantage of them. In the two graphs above, the put call ratio investopedia axis represents the value of the portfolionot the profit or loss, because we assume that traders give options away.

But they don't and the prices of European put and call options are ultimately governed by put-call parity. In a theoretical, perfectly efficient marketthe prices for European put and call options would be put call ratio investopedia by the equation that we noted above:.

Let's continue put call ratio investopedia ignore transaction fees and assume that TCKR put call ratio investopedia not pay a dividend. Say that you purchase a European call option for TCKR stock. Another way to imagine put-call parity is to compare the performance of a protective put and a fiduciary call of the same class. A protective put is a long stock position combined with a long put, which acts to limit the downside of holding the stock.

A fiduciary call is a long call combined with cash equal to the present value adjusted for the discount rate of the strike price; this ensures that the investor has enough cash to exercise the option on the expiration date. Say you also sell or "write" or "short" a European put option for TCKR stock. The expiration date, put call ratio investopedia, strike price, and cost of the option are the same.

The buyer purchases the right, but not the obligation, to sell you TCKR stock at the strike price. This means you are obligated to take that deal, whatever TCKR's market share price.

The profit or loss on these positions for different TCKR stock prices is highlighted in the graph directly above this section. If they go for more, you gain, put call ratio investopedia.

Again, this scenario ignores all transaction fees. Put-call parity allows you to calculate the approximate value of a put or a put call ratio investopedia relative to its other components. If the put-call parity is violated, put call ratio investopedia, meaning that the prices of the put and call options diverge so that this relationship does not hold, an arbitrage opportunity exists. Although such opportunities are uncommon and short-lived in liquid markets, sophisticated traders can theoretically earn a risk-free profit.

Furthermore, it offers the flexibility to create synthetic positions. Put-call parity states that the simultaneous purchase and sale of a European call and put option of the same class same underlying asset, strike price, and expiration date is identical to buying the underlying asset right now, put call ratio investopedia.

The inverse of this relationship would also be true. An option's price is the sum of its intrinsic value, which is the difference between the current price of the underlying asset and the option's strike price, and time value, which is directly related to the time left until that option's expiry. Nowadays, an option's price is determined by using mathematical models, like the well-known Black-Scholes-Merton BSM.

After inputting the strike price of an option, the current price of the underlying instrument, time to expiration, risk-free rate, and volatility, this model will spit out the option's fair market value.
