The graph above depicts the trends in closing stock, the trends in the graph depicts that there has been a decline and then a sharp rise in the closing stock in the last few days.

Volume:

The graph above depicts the volume of stock traded in the past few days, the volume traded has been rising but on the 10th the volume declined slightly.

Hypothesis:

In this paper we will test the relationship between the closing stock, opening stock and the volume traded, we try to investigate whether there exist any relationship between the three variables. We assume that closing stock is the dependent variable and that the volume and the opening stock are the independent variable, therefore the model will be stated as follows:

Y = α + β1X1 + β2 X2

Our estimated model is as follows:

Barnes and Noble

Y = 59.75- 1.68 X1 – 2.83 X2

Therefore the closing stock relationship with the opening and traded volume is negative, to describe this model we hold one variables to be constant and describe the effect of one variable, if we hold all other factors constant and increase the opening balance by one unit then the closing stock will decline by 1.68 units, if in the other hand we hold all other factors and increase the traded volume by one unit then the closing stock will decline by 2.83 units.

We shall now test the statistical hypothesis of the estimated variables, we will test the estimated variables at 95% using the table, our degrees of freedom will be 2, and therefore the value of the critical T is 2.92.

The following table shows the value of T calculated and the decision made in comparison with T critical;

T β1

T β2

-1.21773E-06

Because all the T calculated is less than the T critical then we accept the null hypothesis, therefore all our estimated parameters are statistically insignificant at 95% confidence interval,

however this is attributed to the small sample size used.

However the closing stock will depend on the level of opening stock and the traded volume, the higher the level of volume the less the level of closing stock, also the higher the level of opening stock the lower the closing stock. However there is need to use a large sample size to predict the outcome of closing stock using regression. However the closing stock depends on the opening stock and volume of stock traded.
