What are Synthetic Options Used for?

Synthetic options can be used for a number of reasons. One reason an investorInvestorAn investor is an individual that puts money into an entity such as a business for a financial return. The main goal of any investor is to minimize risk and will enter into a synthetic position is to alter an already existing position when expectations change. This can allow for a position to be altered without closing the pre-existing position. For example, if you are already holding a long positionLong and Short PositionsIn investing, long and short positions represent directional bets by investors that a security will either go up (when long) or down (when short). In the trading of assets, an investor can take two types of positions: long and short. An investor can either buy an asset (going long), or sell it (going short). on a stock, and you are worried about downside riskRiskIn finance, risk is the probability that actual results will differ from expected results. In the Capital Asset Pricing Model (CAPM), risk is defined as the, you might enter into a synthetic call option position by buying a put option.

By creating the synthetic call, you can still hold onto the underlying stock. This can be important if there are other considerations such as a need to hold ownership in the company.

Using synthetic positions can also reduce the number of transactions you need to make, to change your position. For example, take the above situation of changing a long position on the stock to a synthetic call positionCall OptionA call option, commonly referred to as a "call," is a form of a derivatives contract that gives the call option buyer the right, but not the obligation, to buy a stock or other financial instrument at a specific price - the strike price of the option - within a specified time frame. by buying a put optionPut OptionA put option is an option contract that gives the buyer the right, but not the obligation, to sell the underlying security at a specified price (also known as strike price) before or at a predetermined expiration date. It is one of the two main types of options, the other type being a call option.. If you were a trader and wanted to change your position from a long stock position to a call position without the use of a synthetic position you would have to sell the stock and buy the call option. This uses two transactions rather than just buying the put option.

Using fewer transactions can be important in efficient trading strategies. Each transaction will generally come at a cost, so it makes sense to want to reduce the number of transactions whenever possible.

Another reason synthetic options can be used are to employ arbitrageArbitrageArbitrage is the strategy of taking advantage of price differences in different markets for the same asset. For it to take place, there must be a situation of at least two equivalent assets with differing prices. In essence, arbitrage is a situation that a trader can profit from trading strategies. If you can identify a synthetic position that is mispriced with the actual position, then there is an opportunity to profitProfitProfit is the value that remains after a company’s expenses have been paid and can be found on an income statement. Other terms include income and earnings. For example, if a call option costs more than the synthetic call option, you can short the call option and buy the synthetic call option and profitProfitProfit is the value that remains after a company’s expenses have been paid and can be found on an income statement. Other terms include income and earnings.
