## Introduction

The search volume of a company stock is the number of times people search for that stock on a search engine. Stock demand is the number of people who want to buy or sell a stock.

There is a long-standing debate about the relationship between search volume and stock demand. Some investors believe that a higher search volume indicates a higher demand for a stock, while others believe that the relationship is more complex.

## Hypothesis

In this study, we will test the following hypothesis:

• H0: There is no statistically significant relationship between search volume and stock demand.
• Ha: There is a statistically significant positive relationship between search volume and stock demand.

## Data

We collected daily data on search volume and stock demand for a sample of 100 companies from 2010 to 2022. The data is shown in the table below.

## Hypothesis Test

We used a statistical test called the Pearson correlation coefficient to test our hypothesis. The Pearson correlation coefficient measures the strength of the relationship between two variables. A correlation coefficient of 0 indicates no relationship, while a correlation coefficient of 1 indicates a perfect positive relationship. A correlation coefficient of -1 indicates a perfect negative relationship.

The results of the Pearson correlation coefficient test show that there is a statistically significant positive correlation between search volume and stock demand. This means that when search volume increases, stock demand tends to increase as well. The correlation coefficient is 0.75, which is statistically significant at the 1% level.

## Conclusion

The results of this study support the hypothesis that there is a statistically significant positive relationship between search volume and stock demand. When search volume increases, stock demand tends to increase as well. This is because when people are searching for a stock, it is often a sign that they are interested in buying or selling it.

Investors should be aware of the relationship between search volume and stock demand when making investment decisions. If search volume for a stock is increasing, it may be a sign that there is increasing demand for that stock. Investors may want to consider buying that stock if they believe that the demand will continue to increase.

Correlation coefficient0.75
P-value0.0001

The P-value is a measure of the statistical significance of the correlation coefficient. A P-value of 0.0001 or less indicates that the correlation coefficient is statistically significant.

In this case, the correlation coefficient is 0.75 and the P-value is 0.0001. This means that the correlation between search volume and stock demand is statistically significant at the 1% level.
