Puts are more or less the mirror image of calls. The put buyer expects the price to go down. Therefore, he pays a premium in the hope that the futures price will drop. If it does, he has two choices: (1) He can close out his long put position at a profit since it will be more valuable; or (2) he can exercise and obtain a profitable short position in the futures contract since the strike price will be higher than the prevailing futures price.
Whether the economy is hot or not, an investor can make money trading commodity options, regardless of the condition of the market. Briefly, a commodity option allows its owner to either sell or buy a commodity like corn or wheat at a future date. You will buy a so-called “put option” if you think the price of the commodity will go down and a “call option” if you think the price will rise. And never will you have to take possession of the commodity itself.
The price at which you agree to buy the underlying security via the option is called the "strike price," and the fee you pay for buying that option contract is called the "premium." When determining the strike price, you are betting that the asset (typically a stock) will go up or down in price. The price you are paying for that bet is the premium, which is a percentage of the value of that asset.
