It is well a bigger number of volumes than the other data.

But, in the middle of September 2008, the stock price level of CEKA was going down. It probably happened because of the global crisis. Like what it is known, global crisis and recession happened between middle of 2007 until 2008 to around the world. But, the effect of global crisis could be felt by Indonesian company in the middle of 2008 until in the middle of 2009. That’s why the stock price of almost all companies in Indonesia stock market including CEKA, was going down in that period. Global crisis can also affect Indonesian stock market because many of investors are foreign investors. If they are bankrupt, then they couldn’t invest their money in Indonesia. Besides that, some Indonesian companies are doing export-import. If the foreigners are bankrupt, how they can buy Indonesian companies product. So, global crisis also has effects to Indonesian stock market including CEKA.

2. c. The Average, Standard deviation, Highest and Lowest

2. d. Explanation and Analysis of the Average, Standard deviation, Highest and Lowest result

Average

The average calculation results will be used in the calculation of standard deviation and to determine the data’s dispersion.

Standard Deviation

The standard deviation is used in statistics to measure the variability or dispersion of a data set. If the data are very close to the average value, we have a small standard deviation. If the data are dispersed over a wide range of values then we have a large standard deviation.

From the table above, we can see that in the volume element, we find that there is significant difference between the average (47.0405) and the standard deviation (152.4456). From that number, the standard deviation is very high. It is mean that there is a great dispersion in volume or we can say that the volume has high volatility.

In this case, it can be seen that the data collected is highly dispersed. This situation indicates a risky condition to having stock in PT Cahaya Kalbar. The background is come from the result of standard deviation calculation. Because of the standard deviation is high, so this company’s stock exchange price has high possibility to change, which mean that the price is not stable.

Highest and Lowest Analysis

From the table, it can be seen that the highest volume is 1883 and the lowest is 0. The highest volume reached in March 13^th, 2008, it can be analyzed that it happened because in March 2008 the sales of PT Cahaya Kalbar increased dramatically five times of 463.5% and became Rp 595,551 billion and the net profit (after deducted by tax) also increased from Rp 617 millions or Rp 2.1 per stock in the first three-semester of 2007 to Rp 35,972 billion or Rp 121 per stock. People invest money to get return, so they want to invest their money in a company with big profit. That’s why the volume in March is the highest volume. While, for example in January 29^th until February 5^th, 2008, the volume is 0 because there is nothing special happened in those dated and besides that, PT Cahaya Kalbar is still in unstable company category if it is seen from the pattern of the graph.

Next, for the closing stock price level, the highest level is Rp 2000 per stock in June, while the lowest level is Rp 650 per stock in October. The range between the highest and the lowest is very high. It shows that the company has high risk. High risk means that the stock price has unpredictable changes.

3. Conclusion

To analyze the company performance, it is not only based on trend line record but also using standard deviation calculation. From the calculation, the data are dispersed or the data has a high volatility. With high volatility, it means that the stock price has a high possibility to change. From stockholder point of view, the higher changing possibility indicates the higher risk for stockholder to have the stock.

Based on graphical data and calculation, this company has good prospect in future but risky in stock price’s stability
