#2 - Seasonal trends in corn futures chart

Corn is a highly seasonal commodity with trading subdued during the winter months while the summer months can show wild swings in prices. The seasonal trends in corn are based on the plantation and harvest periods. Corn is typically planted in spring and harvested during the fall months. The period between planting and harvesting is one of the most volatile months for corn futures as speculators start to move prices around based on expected supply and demand factors. The winter months are usually the quietest periods in corn futures where most of the trading in the corn futures are based on the week to week shifts on the demand side of the spectrum. On the other hand, during the summer months, corn futures traders need to focus on many different aspects such as weather which could evidently impact the harvest.

Price action in corn futures is relatively flat during the first few months of the year and volatility picks up around early April or May. As the planting season comes closer, the volatility in corn futures starts to increase as well with the highest action seen during the June and July months. It is also around this same period that corn futures tend to make a seasonal high before price start to pull back. The August and September months typically see corn futures moving sideways on a long term basis before volatility picks up around the late October period and into the winter months.

#3 - USDA reports and influence on corn futures contracts

The United States Department of Agriculture (USDA) releases a set of report which usually set the expectations in the supply and demand on a very fundamental basis. One of the reports issued by the USDA is the Planting intentions report which comes out during end of March. The report gives an overview of the market for the season and highlights key information as the amount of acreage that farmers intend to plant for the crop. In early January, the USDA releases the annual crop summary which gives a comprehensive view of the production numbers for the previous year and also gives information on the stocks of corn at all positions towards the end of the year. This gives an overview on the potential harvest that comes out from the plantation area. There are some technical aspects to the report as well as most analysts have come up with a calculation of multiplying the acres by a trend yield to project the expected crop for the season. Besides the March report, the USDA also releases a weekly export report every Thursday. This report gives details on the demand for corn exports. A strong export market usually bodes well for corn futures prices. Corn futures traders also need to pay attention to the price of corn from other exporting countries. If the pricing of Corn from the U.S. is not competitive enough, demand tends to quickly fall off.

#4 - Effects of weather on corn futures prices

Weather plays a crucial role in almost any commodity that requires sowing and harvesting and Corn is not immune from this. The climate effects on the corn plantation can have either a near term or a long lasting effect which could potentially influence the prices of corn futures. As corn futures traders and more importantly for day traders it is best to do some research before entering a position. Due to the various weather departments that can issue reports, it is not hard to see surprise volatility in the corn futures. Doing a bit of research beforehand for any upcoming weather report releases can be helpful to the corn futures traders. No matter how strong one's analysis is of the corn futures markets; accounting for the weather plays a bit role and is one of the fundamental factors that can affect the price of corn futures.

#5 - Ethanol demand and impact on corn futures prices

Believe it or not, ethanol prices play a major role in influencing the price of corn futures. This is because corn is the main feedstock in the U.S. for producing ethanol fuel. Over 40% of corn goes into fuel production while the remainder goes towards feed for livestock (which tends to influence prices of cattle futures) and only a small portion of the supply goes towards human consumption. Ethanol is mostly used a fuel additive. Between the periods of 2013 - 2014 over 13 billion bushels of corn were produced of which a majority went into ethanol production. Over 98% of ethanol production comes from corn. It is estimated that one bushel of corn can produce 2.8 gallons of ethanol. Demand for ethanol has been in a steady increase since the 1970's as the U.S. government mandated an increase of ethanol in gasoline and other similar products. In 2011, the U.S. Environmental Protection Agency allowed up to 15% of ethanol blended gas to be sold commercially A higher demand for ethanol leads to higher demand in corn as well thus leading to higher prices. The positive relationship between ethanol and corn is higher during cycles of expansion but the relationship is not that strong during periods of weaker demand.

#7 - Supply and Demand – Impact on corn prices

Supply and demand forms the basis for any commodity. It is simply a reflection of the market dynamics and can significantly influence price of the commodity, corn in this context. Corn futures traders should pay attention to the demand side which can potentially run up or down the price of corn futures. China being the world's second largest economy and a big emerging market economy can have strong influence on demand for corn futures (both for human consumption and energy demand). The United States is the world's largest corn exporter but it accounts for less than 15% of the demand. Besides the U.S. other major corn exporting nations include Brazil, Ukraine, Russia, India and South Africa. The demand for corn from China can be volatile and varies from one year to another making it a significant source of uncertainty on the demand side. Still, China does have the influence to impact corn prices. Corn futures traders can keep track of this data by looking for any key releases from China which is often widely reported in the media. The corn futures markets are no doubt an exciting futures commodity that can be traded and day traders in the futures markets can look at making potential gains from trading corn futures contracts. However, there are a lot of factors that one needs to bear in mind such as the time of the year, demand and supply as well as the year’s projection on the corn markets. Take into consideration all the above factors listed in this article to trade corn futures successfully.
