The purchase of a call option is a long position, a bet that the underlying futures price will move higher. For example, if one expects corn futures to move higher, they might buy a corn call option. The purchase of a put option is a short position, a bet that the underlying futures price will move lower. For example, if one expects soybean futures to move lower, they might buy a soybean put option.

Options trading may seem overwhelming, but they're easy to understand if you know a few key points. Investor portfolios are usually constructed with several asset classes. These may be stocks, bonds, ETFs, and even mutual funds. Options are another asset class, and when used correctly, they offer many advantages that trading stocks and ETFs alone cannot.

Traders that are willing to accept considerable amounts of risk with the prospects of limited reward, can write (or sell) options, collecting the premium and taking advantage of the well-known belief that more options than not expire worthless. The premium collected by a commodity option seller is seen as a liability until the option is either offset (by buying it back), or it expires. This is because as long as the option position is open (the trader is short the commodity option), there is substantial risk exposure. Should the futures price trade beyond the strike price of the option, the risk is similar to holding a commodity futures contract outright.

Commodity options provide a flexible and effective way to trade in the futures markets. Further, options on futures offer investors the ability to capitalize on leverage while still giving them the ability to manage risk. For example, through the combination of long and short call and put options in the commodity markets, an investor can design a trading strategy that fits their needs and expectations; such an arrangement is referred to as an option spread. Keep in mind that the possibilities are endless and will ultimately be determined by a trader's objectives, time horizon, market sentiment, and risk tolerance.
However, options are not the same thing as stocks because they do not represent ownership in a company. And, although futures use contracts just like options do, options are considered lower risk due to the fact that you can withdraw (or walk away from) an options contract at any point. The price of the option (its premium) is thus a percentage of the underlying asset or security.
