Now, looking from the impact of capital market, we can see significant return from LQ45 in February 1, 2010 that the return until -0.999 (the number almost -1). The graphic of the return of LQ45 is down significantly. The same condition also happened in IHSG, the market return of IHSG also in minus number (suffered losses). But, it is not give the big impact to the stock return of BISI because BISI still can give the gain for 0.051948 or 5.195% from the total investment.
Then in 2008, Augusts 13, we can see that the return of investment in the capital market show the indexes both LQ45and IHSG gave the capital gain only in small value.

This number of return is the highest rate of return from 2008 until March 2010.
This proved that the condition of stock in BISI not too much affect by macroeconomics condition that represent by the market index both of LQ45 and IHSG. In other word, the return of BISI stock not sensitive with condition of economic in Indonesia. The condition of stock isn’t suffered by fluctuation like the economic condition.

Analysis of Beta (ß)

We can get the regression analysis from the daily market return and daily stock return. Daily market return consists of IHSG and LQ45 for period January 2, 2008 until March 31, 2010. We use regression analysis to find the beta to know the sensitivity of a stock’s return on the market portfolio. So we can know how the condition of capital market influences the stock of the company. In this case, risk depends on exposure to macroeconomic events and can be measure as the sensitivity of a stock’s return to fluctuations in returns on the market portfolio.
In the regression analysis, we use stock return as dependent variable and market return as an independent variable because we want to know how the capital market that represent the macroeconomics condition influences the movement stock of BISI international. In the first regression analysis, we used daily market return of IHSG as independent variable and stock return as a dependent variable. The result of the beta is 0.968 (less than 1). The slope is 0.968. This means that for each increase of 1 in X, the mean value of Y is estimated to increase by 0.968. In other word, for each increase of 1% of return in the market, the mean values of risk are estimated to increase by 0.968%. Thus, the slope represents the portion of the daily stock return that is estimated to vary to the market return. The Y intercepts is 5.00765E-05 = 0. The Y intercept represents the mean value of Y when X equals 0. Because the percent of the market return can be 0, this Y intercept has practical interpretation.
Then for the result of regression analysis between LQ45 and BISI international based on market and stock return. The slope is 0.146. This means that for each increase of 1 in X, the mean value of Y is estimated to increase by 0.1461. In other word, for each increase of 1% of return in the market, the mean values of risk are estimated to increase by 0.146%. Thus, the slope represents the portion of the daily stock return that is estimated to vary to the market return. The Y intercepts is 0.000521 = 0. The Y intercept represents the mean value of Y when X equals 0. Because the percent of the market return can be 0, this Y intercept has practical interpretation.
We know that Beta that based on LQ45 is smaller than IHSG. LQ45 is 0.146 and beta for IHSG is 0.968. So the sensitivity of BISI in IHSG is bigger than LQ45. The condition of market in IHSG is more representative to the condition of stock in BISI than LQ45. It happened because LQ45 just consist of 45 companies that active in trade and it different with IHSG that consists of many company both active or not.
The both result of beta proved that BISI is a defensive stock (the result of beta smaller than 1). Why? Betas greater than 1 meaning that their return tend to respond more than one-for-one to changes in the return of the overall market (condition of aggressive market). The betas of defensive stock are less than 1, the returns of these stocks vary less than one-for-one with market returns. Defensive stock is a stock that tends to remain stable under difficult economic conditions. The stock BISI International is defensive stocks because that company operating in food industry. These stocks hold up in hard times because demand does not decrease as dramatically as it may in other sectors. Defensive stocks tend to lag behind the rest of the market during economic expansion because demand does not increase as dramatically in an upswing.
Looking from the type of stock, Investor that likes to use defensive investment strategy can include BISI in their portfolio. Portfolio management strategy aims at investing in low-risk products. Stock of BISI is defensive stocks because undervalued (the value of return in stock less than market), less volatile, steadily growing, and offering reasonable dividends. The main advantage of a good defensive investment strategy is the minimized risk of losing the capital. Other advantages include better planning of investments, almost steady and predictable income, and better use of risk-minimizing practices like close stop-losses. Beginner investors can invest their fund in BISI because BISI have less risk-tolerance and investors having less time to monitor their portfolio.
