Futures and Options Contracts
Open a brokerage account that will allow you to trade futures, options and stocks (see Resources below for suggestions).
Buy an options or futures contract on rice. The ticker symbol for rice is ZR. You will need a minimum margin of $2,430 for a futures contract and $250 for an options contract.
Enter the ticker symbol into the brokerage software and click on "Search." This will bring up a list of rice-related products and their contract dates.
Select the month of the contract that you wish to purchase and the price that you wish to buy it at under the “Limit” price. Click on “Buy” or “Submit Order.” When the price of the contract is reached, the software will automatically purchase the contract.
Stocks and ETFs
Buy a stock or exchange traded fund (ETF). Since rice producers are not publicly traded companies you cannot purchase their stock directly. You can, however, buy the stock of companies related to the production of rice.
Buy stock from companies that make pesticides and seed-related products related to rice. You can research these types of companies at MarketWatch.com or Morningstar.com.
Buy an exchange traded fund (ETF). These are funds that invest in several different, but related companies for diversification. There are several agricultural ETFs that you can consider. These include the ELEMENTS Rogers International Commodity fund (NYSE: RJA), the iPath DJ AIG Agriculture Fund (NYSE: JJA) and the PowerShares DB Agriculture ETF (NYSE: DBA).
