Recap of last week’s holdings
I was holding short contracts for all 3 commodities last week because prices fell quite dramatically. (Ex. I was holding 9 short contracts for wheat and 11 short contracts for soybeans!) A few of my colleagues have cautioned me against this as it is challenging to accurately predict the market’s movement, thus probably impractical to hold too many short contracts in the long run–> subjecting myself to too many risks should the market turn around.
—————————————————————————————————————–

As Bernanke announced that no additional dollar printing will occur now in the US, there will then be a limited supply leading to appreciation and lowering prices of commodities. The US dollar has strengthened to its highest value in 11 months. However, this could possilby create psychological barriers amongst traders in US dollar investments as it has been depreciating steadily this year. I predicted that the prices of commodities would rebound a bit since they have fallen in prices over the last week, and traders are taking more caution towards the US dollar appreciating.

Although corn production has increased to 16 tonnes in Ukraine, it was originally estimated to be over 18 tonnes this harvest. News also reported that traders are believeing that the corn market is oversold. From the technical analysis p.o.v, the corn market looks bearish in the short-term, but with news that global demand for corn is expected to be increasing, I predicted that it would lean towards the bullish side on the long-run. All these factors, on top of my intention to offset some of my short contracts, I decided to take a long position on 5 contracts for corn.
Corn -> 5 long contracts @ 645cents (592.4-645)*5*50 = -13150

It is believed that soybeans have been oversold last week due to their rapid fallen prices. Reports state that the production of soybeans in this harvest period has been lower than what they had expected. From the technical analysis view, prices are fluctuating quite a bit with soybeans prices and since I am holding 11 short contracts, I have decided to attempt in offsetting some of my contracts to reduce my risks.Soybeans 5 long contracts @ 1252 (1179-1252) *5*50 = -18250.

Dry weather has been a setback for wheat crops, affecting 80% of winter grain production. Moreover, the lack of humidity on the soil’s surface is increasing the concerns of sowing for farmers. With predictions on our WIKI blog that wheat prices may go up, and with my holdings of 9 short contracts, I decided to try offsetting some by taking a long position with 5 contracts.Wheat 5 long contracts @ 650 (609.2-650)*5*50 = -10200;

My margin balance is currently 79650. I am holding  2 long contracts for corn, 6 short contracts and 4 short contracts for soybeans and wheat, respectively. As news today reported that the corn prices have fallen again, and the outlook is extremely bearish according to technical analysis, I am planning on offsetting my long contracts for corn next week.

PS. I have also learned that I should not freak out over the number of short contracts that I was holding. I should trust my research and decide on which factors would affect the price movement the most significantly, and then place my bid accordingly. If the price is, say going to decrease, then the more short contracts under my belt, the more profitable I will be. Afterall, taking sensible risks is what bidding is about!

For Sept. 20th Tuesday

Investors are favouring the US dollar over fears of the Euro Debt. Thus, US dollar is strengthening and I predict that the prices of commodities are going to lower. However, rumours have that China is going to demand a significant amount of corn from the US. This would decrease the supply of corn, and I predict that the price would then be forcasted to increase.

Since corn is going to increase in price, I will bid for a long position on 5 contracts at 690 cents. So if price does go up in the future, I would be able to profit from selling it at a higher price than now. However, for the remaining 2 crops, I am going to hold 5 short contracts each because I predict that the prices would continue to decrease. If it does indeed decrease in the future, then I would still be able to sell it at the higher price that I am bidding at right now.
Profit: Corn -> 5 long contracts @ 690cents (690.2-690)*5*50 = 50; Wheat 5 short contracts @ 671 (671-674.6)*5*50 = -900; Soybeans 5 short contracts @ 1335 (1335-1338) *5*50 = -750.

For Sept 21 Wednesday

Between these couple days, the US dollar has been experiencing slight fluctuations (although it is increasing in value overall)  as some claim it to be a safe haven and others don’t. Thus, I decided to observe the different factors for a little longer before jumping into the bids again. However, a news article reported that soybean production is up 16% from 2010, as well as technical analysis also shows the trend to be extremely bearish, so I decided to bid 3 short contracts. Profit: soybeans 3 short contracts @ 1340, (1340-1345.2)*3*50 = -780.

For Sept. 23 Friday

The US dollar continues to strengthen, driving commodity prices even lower. In fact, soybeans in particular is reported in the news to reach the lowest drop in 2 years because of recession fears building up. However, wheat prices are seen to be fluctuating quite a bit and not decreasing as much on the technical analysis side. However, it is still forcasted to be decreasing, but just may not be as rapid as the other 2 commodities. So, I decided to take 5 short positions each for corn and soybeans, and 2 for wheat.
Profit: Corn 5 short contracts @ 653, (653-638.4)*5*50=3650; Soybeans 5 short contracts @ 1267, (1267-1258)*5)50= 2250; Wheat 2 short contracts @ 640, (640-640.6)*2*50= -60
_______________________________________________________________________

Currently, I am holding 3, 11, and 9 short contracts for corn, soybeans and wheat, respectively. I am earning money in the game as my margin balance is now 1132700. So far, I have made 1107700. I am going to hold my positions and observe the market movement, and then take action as to what I will do next.

Corn/Soybeans Futures fall, Wheat rises http://www.washingtonpost.com/business/markets/corn-oat-and-soybean-futures-fall-but-wheat-futures-rise-on-the-cbot-livestock-prices-rise/2011/09/23/gIQAH1r9qK_story.html

According to the findings posted on WIKI-blog, I have deduced the expectations that prices of commodities would rise. Dry weather in the US that has severely damaged crops in the past month, depreciating US dollar over the past while, decreased yield in crop production are all factors that may most likely contribute to the increase in commodity prices.

However, from Twitter announcements as well as agriculture articles, prices cannot increase in just overnight’s time – there would be a period where they adjust into the upward trend. So, I have decided to take advantage of this incubation period in taking long positions on my bids before prices start to rise.

Sept. 14th
Corn: took a long position for 2 contracts, bidding 710. Unsuccessful as the lowest price reached that day was 716.4

Wheat: long position for 2 contracts, bidding 688. Again, too low of an estimate as the market dipped till only 698.

Soybean – decided to observe a bit more as I read updates on a sudden increase in supply due to the occurance of a heavy rainfall in the US.
_________________________________________________________________________
Unfortunately, I estimated the prices to be lower than it really became, so I was unsuccessful in taking a long position to enter the market. I studied up on the trends of the pricing from the past few months, with aid from the findings of our technical analysis group. I decided to bid again on Wednesday.

Sept 15
Corn: took a long position with 2 contracts at a bid of 715. Loss of profit that day as I bought it at a more expensive price – it reached a low of 700.2.

Soybean: I concluded from all my readings and research that soybean production is going to increase because of an unexpected heavy rainfall in the US, and thus the price of soybeans would decrease. I bid for 2 long contracts at 1375, and had a loss of profit that day as it dipped even lower to 1356.4.

Wheat: From diagrams and data that illustrated the trend of wheat prices, I expected that the price would rise. I then took a short position for  2 contracts at 702. However, the highest price that it reached that day was 705.6, so I underestimated the peak to be a little lower that day.
____________________________________________________________________

As of this moment, I am holding long positions with 2 contracts each on corn and soybean at bids of 715 and 1375, respectively. I am also holding a short position on wheat with 2 contracts at 702. Currently, I am losing money in the game as my margin balance is now 22120. I have lost so far, 2880. So before I make any more decisions, I am going to hold my positions and observe the market movement, and then take action as to what I will do next.
