Understanding Vanilla Options
Let me start by telling you what a vanilla option really is. It's a financial instrument that gives you, the holder, the right—but not the obligation—to buy or sell an underlying asset at a predetermined price within a given timeframe. Essentially, a vanilla option is just a standard call or put option without any special or unusual features. If you're trading these on an exchange like the Chicago Board Options Exchange, they're standardized, which makes things straightforward.
Key Takeaways
You need to know that vanilla options let you purchase or sell an underlying asset at a pre-determined strike price within a defined timeframe. They consist of call and put options, which give you the right, but not the obligation, to buy or sell that asset. Plus, you can combine them with exotic and binary options to create custom outcomes that fit your strategy.
Basics of a Vanilla Option
Individuals, companies, and institutional investors use vanilla options to hedge their exposure in a particular asset or to speculate on the price movement of a financial instrument. If a vanilla option doesn't quite fit what you need, consider exotic options like barrier options, Asian options, or digital options—they're more customizable. These exotic ones come with complex features and are usually traded over the counter. You can combine them into structures to cut net costs or boost leverage.
Calls and Puts
There are two main types of vanilla options: calls and puts. As the owner of a call, you have the right, but not the obligation, to buy the underlying instrument at the strike price. For a put, you have the right to sell it at that strike price. The seller, or writer, of the option takes on the obligation to buy or sell if you exercise it.
Both calls and puts come with an expiry date, which limits how long the underlying asset has to move in your favor. Take stock XYZ trading at $30, for example. A call option expiring in one month with a $31 strike price might have a premium of $0.35. Since each contract controls 100 shares, that costs you $35 total.
If XYZ rises above $31, the option is in the money, but you need it to go above $31.35 to profit after the premium. Your maximum loss is just the premium paid, while profits can be unlimited based on how far it moves. The writer collects that $35 premium. If it stays below $31, they keep it as profit. But if it hits $33, they face a $165 loss after accounting for the premium—calculated as ($33 – $31) x 100 minus $35.
Vanilla Option Features
Every option has a strike price. If it's better than the market price at maturity, the option is in the money and can be exercised. With European style, you can only exercise if it's in the money on expiration day. American style lets you do it anytime before or on expiration if it's in the money.
The premium is what you pay to own the option, determined by how close the strike is to the current price, the asset's volatility, and time until expiration. Higher volatility or longer time means a higher premium. An option gains intrinsic value as the underlying moves past the strike—above for calls, below for puts.
You don't have to wait until expiry to close a trade or exercise. You can just take an offsetting position anytime to lock in profits or cut losses.
Exotic and Binary Options
You can combine two other types of options with vanilla ones for tailored results. Exotic options have conditions or calculations tied to their execution. For instance, barrier options activate or deactivate if a certain level is reached. Digital options pay out if the underlying is above or below a specific price. Asian options base payoffs on the average price over the option's life.
Binary options, the other type, limit outcomes to just two possibilities, so payouts are restricted too. They're often used to speculate on asset price movements. One combination could be buying a vanilla call or put and a binary in the opposite direction.
