“Buy to open” is a term used in the context of options trading, signifying the opening of a new long position—either a call or a put option. When traders employ this strategy, they are essentially purchasing a contract that grants them the right, but not the obligation, to buy (call) or sell (put) an asset at a predetermined price before a specified expiration date.
How “Buy to Open” Works
Long Call Option
A long call option gives the buyer the right to purchase the underlying asset at a set price (strike price) within a specified timeframe. If the asset’s price increases significantly above the strike price, the trader stands to make a profit.
Long Put Option
Conversely, a long put option provides the buyer with the right to sell the underlying asset at the strike price within the specified period. This is beneficial when the trader anticipates a decline in the asset’s price.
Special Considerations
Initial Costs
When executing a “buy to open” order, traders must pay a premium. This upfront cost is the price of entering the contract and is influenced by factors such as the underlying asset’s market price, the time until expiration, and market volatility.
Risk and Reward
Both long call and put positions have limited downside risk (loss of the premium paid). However, their upside potential can be significant, particularly for long call options in bullish markets or long put options in bearish conditions.
Time Decay
Options are time-sensitive financial instruments. The value of options diminishes as the expiration date approaches—a phenomenon known as time decay, which traders must consider when planning their strategies.
Example
Consider a trader who believes that the stock of Company XYZ, currently priced at $50, will rise significantly in the next three months. The trader might “buy to open” a long call option with a strike price of $55 that expires in three months. If XYZ’s stock rises to $70, the trader can exercise the option to buy at $55, thereby making a profit (minus the premium paid).
Historical Context
Options trading has evolved over centuries, with its roots traceable to ancient civilizations. Modern options markets began to take shape in the 20th century, with the establishment of formal exchanges like the Chicago Board Options Exchange (CBOE) in 1973. The term “buy to open” has become standard nomenclature within these markets.
Applicability and Comparisons
Comparisons to “Sell to Open”
“Buy to open” is often contrasted with “sell to open,” which involves opening a new short position. While “buy to open” positions benefit from favorable movements in the underlying asset’s price, “sell to open” positions profit from the premiums collected and stable or opposing movements in the underlying asset.
Relation to Other Trading Terms
- Long Position: Holding an asset with the expectation that its value will increase.
- Short Position: Borrowing an asset to sell it immediately, with the intention of buying it back later at a lower price.
