Let us begin diviidends defining arbitrage and how arbitrage opportunities dlvidends the markets. Arbitrage is, generally speaking, the opportunity to profit arising from price variances on one security in different markets. For example, if an investor can buy XYZ in one market and simultaneously sell XYZ on another market for a higher price, the trade would result in a profit with little risk.
The buying and selling pressure in the two markets will move the price difference between the markets towards equilibrium, quickly eliminating any opportunity for arbitrage. That is, we can determine the value of a financial instrument if we assume arbitrage to be unavailable. Using this principle, we can value options under the assumption that no arbitrage opportunities exist.
When trying to understand arbitrage as it relates to stock and options markets, we often assume no restrictions on borrowing money, no restrictions on borrowing shares of stock, and no transactions costs. In the real world, such restrictions do exist and, of course, transaction costs are present which may reduce or eliminate any perceived dividendw opportunity for most individual investors. For investors with access to large amounts of capital, low fee structures and few restrictions on borrowing, arbitrage may be possible at times, although these opportunities are fairly rare.
Options are derivatives; they derive exchange options put call parity with dividends value from other factors. In the case of stock options, the value is derived from the underlying stock, interest rates, dividends, anticipated volatility and time to expiration. There are certain factors that must hold true for options under the no arbitrage principle. If the September call is less expensive, investors would buy the September call, sell the June call and guarantee a profit.
Note that XYZ is a non-dividend paying stock, the options are American exercise style and interest rates are expected to be constant over the life of both options. Here is an example of why a longer term option premium must be equal to or greater than the dividwnds of the short term option. If the June premium was higher like in the exampleinvestors would sell the June call, causing the price to decline and buy the September, causing the price of that option to rise.
These trades would continue until the price of the June option was equal to or below the price of the September option. A similar relationship can be seen between two different strike prices but the same expiration. With stock and options, there are six possible positions from three securities when dividends and interest rates are equal to zero — stock, calls and puts: Synthetic relationships with options occur by replicating a one part position, for example long stock, by taking a two part position in two other instruments.
Similar to how synthetic oil is not extracted from the fossil fuels beneath the ground. Pairty synthetic oil is divicends with chemicals and is man-made. Similarly, synthetic positions in stocks and options are generated from positions in other instruments. The call and put would have the same strike price and the same expiration.
By taking these two combined positions long call and short putwe can replicate a third one long stock. Remember the put premiums typically increase when the stock prices decline which negatively impacts the put writer; and of course the call premiums typically increase as the stock price increases, positively impacting the call holder.
Therefore, as the stock rises, the synthetic position also increases in value; as the stock price falls, optiond synthetic position also falls. An investor can purchase the call and write the put. In the previous example, if the relationship did not hold, rational investors would buy and sell the stock, calls and puts, driving the prices of the calls, puts and stock up or down until the relationship came back in line. Eventually the buying of the calls would drive the price up and the pagity of the puts would cause the put premiums to decline and any selling of the stock would cause the stock price to decline also.
Other factors too will change the relationship — notably dividends and interest rates. The previous examples show how the markets participants would react to a potential arbitrage opportunity and what the impact may be on prices. The strike price of the call and put are the same. This assumes the strike prices and the expirations are the same on the call and put with interest rates and dividends equal to zero. The next logical question is how ordinary dividends and interest rates impact the put call relationship and option prices.
Interest is a cost to an investor who borrows funds to purchase stock and a benefit to investors who receive and invests funds from shorting stock typically only large institutions receive interest on short credit balances. Higher interest rates thus tend to increase call option premiums and decrease put option premiums. Long stock requires capital.
The cost of these funds suggests the call seller must ask for higher premiums when selling calls to offset the cost of interest on money borrowed to purchase the stock. Conversely, the offset to a short put is short stock. As a short stock position earns interest for some large investors at leastthe put seller can ask for a lower premium as the interest earned dividneds the cost of funds. This reduces the cost of opions — as the cost of carrying the stock position into the future is reduced from the dividend received by holding the stock.
Opposite of iwth rates, higher dividends tend to reduce call option prices and increase put option prices. Professional traders understand the relationships among calls, puts, interest rates forex trading career path explanation dividends, among other factors. For individual investors, understanding the early exercise feature of American style options is essential.
