Investment Decisions through Total Asset Growth toward Price to Book Value on the Jakarta Islamic Index

This research analyzes the effect of investment decisions through Total Asset Growth (TAG) on Price to Book Value (PBV). Since PVB indicates stock measurement based on the ratio of stock price to book value, it is used by investors to assess the price offered. This research uses time-series data from 2014-2020 to examine seven companies selected using purposive sampling but based on fairly good asset developments from 2014 to 2020. Furthermore, this quantitative causal study data were collected using documentation from various sources and analyzed using a simple linear regression test. The results show that the TAG variable has no effect on PBV. This shows that TAG does not describe a stable company and is not always useful in investment decision-making.


INTRODUCTION
Economic development in a country can be measured by capital market as an investment institution with other important financial and economic functions (Hidayati, 2010;Anggraini, 2015). According to Pardiansyah (2017), capital market is not limited to those with much investment capital. The transactions are also given to companies that need long-term business funding sources (Noerirawan & Muid, 2012). In economics, one of the capital market functions is to provide funds or investment to those in need (Jozwiak, Marszalek, & Sekula, 2015). With this investment, the investors hope for a refund from the fresh funds disbursed (Devianasari & Suryantini, 2015).
The capital market is a characteristic of the economy compared to other markets (Dewi, Adnantara, & Asana, 2017). This means that its product quality is uncertain but one of the offerings in its activities (Afzal & Rohman, 2012). Before investing in the capital market, the main requirement is security (Arifah & Roifah, 2013). This is obtained by getting accurate, clear, and reasonable accounting information as an indicator to assess investment risk by predicting the returns (Nasehah, 2012). Investors in the stock market aim at increasing capital to obtain high profits for themselves and the company with various consequences (Anggraini, 2015). Therefore, a portfolio with a profitable value is needed to determine the value and individual to which the investment is given. This portfolio could be obtained from the bookkeeping reports provided by the company to the public (Wijaya & Wibawa, 2010).
One of the obligations to be fulfilled for go-public companies is to inform the general public of financial statements (Mukhlis, 2017). Accurate, clear, and broad information is useful for investors to know the company financial condition (Affandi, Sunarko, & Yunanto, 2019).
The basic purpose of investment is to obtain profits through dividends and the difference between buying and selling stocks (capital gains) (Sondakh, 2019). Furthermore, through financial statements, investors assess the company's performance in generating profitability and the amount they would receive (Murniati, Mus, Semmaila & Nur, 2019).
Investors would be faced with the choice of profit or loss, meaning that they need to always prioritize the precautionary principle before channeling their funds (Devianasari & Suryantini, 2015). Based on the risk and return by investors, it is common for them to change the form of investment (Rahmanto, 2017). This could create a movement in the capital market as a reflection of changes in investment.
Stock valuation is important information before investing in the capital market. Hartono (2015); and Nasution, Putri and Dungga (2018) stated three valuation indicators used to value stocks, including book, market, and intrinsic values. The three indicators are needed as information to assess the company's growth and development.
The intrinsic stock value could be determined using the Price to Book Value (PBV) approach. PBV assesses stock sales activities on the capital market and is essential in determining intrinsic value (Wijayanti, Nur & Setyo, 2016). It describes the value of assets owned by companies, such as securities in the form of stocks (Wijaya & Wibawa, 2010). The company condition greatly affects the high and low stock prices in the market.
PBV is a comparison used to evaluate the financial performance of a company. It shows how a company creates value relative to the capital invested with what has been or is being invested by the company owner (Wijayanti et al., 2016). In this case, a company runs well when the PBV ratio is above one or when the market value is higher than the book value (Annisa & Chabachib, 2017;Sondakh, 2019). Therefore, the higher the PBV value, the greater the additional wealth enjoyed by the owner (Afzal & Rohman, 2012). Furthermore, according to JII, the high PBV value shows that the market recognizes the company's prospects (Wijayanti et al., 2016). Pardiansyah (2017) stated that, in purchasing Price to Book Value (PBV), the stock capital market comprises several indicators. These are Total Asset Growth (TAG), Debt to Equity Ratio (DER), and Dividend Payout Ratio (DPR). However, in the capital market, the PBV purchase is more affected by TAG because it is useful as capital in case the company is in a downstate (Zulvia, 2019). This supports Nasution, Putri, and Dungga (2018), which showed that the TAG indicator is one part considered by investors before buying PBV during global economic uncertainty. Furthermore, it becomes the most important part by investors before calculating the DER and DPR. This is because the significant development of TAG is one of their targets during global economic uncertainty (Annisa & Chabachib, 2017).
Buying a stock means purchasing the future of a company. PBV provides an overview and information about the book value of a company's stock and could include market prices. Therefore, it could be considered for an investor to determine an investment strategy in the capital market. A high PBV value illustrates stockholders' prosperity and gives them consideration and confidence in the company's future condition (Rahmanto, 2017). Investors use PBV to choose which stock to buy, meaning that it predicts overvalued or undervalued stocks (Marlina, 2013).
One of the indicators in determining PBV is TAG in the capital market (Hartono, 2015). The decrease of TAG in 2015 was due to the impact of the global economic recession (Tanjung & Siregar, 2018). In contrast, this did not affect PBV, whose value increased between 2014 and 2015. Furthermore, the global economy fell in 2020 due to the pandemic, though PBV consistently increased because it was the company's asset deposit during a financial decrease (reference). Fluctuating TAG values and consistent PBV prices make investors believe that TAG is an important indicator taken in investment decision-making (Dewi et al., 2017;Listyaningsih & Krishnamurti, 2015). An increasing and developing TAG becomes an important company capital, attracting investors' attention (Wijaya & Wibawa, 2010).
However, the effect of TAG on PBV in companies listed on the Jakarta Islamic Index needs to be analyzed by comparing several research timescales.
Several studies examined the effect of Total Asset Growth on Price Book Value and found different results. For instance, Nasehah (2012) and Widyakto and Ariefiantoro (2020) stated that growth did not affect PBV. Conversely, Pangulu and Maski (2014) showed that total asset growth significantly affects PBV. Therefore, TAG on PBV becomes interesting to study.

METHOD
This is a causal study with Total Asset Growth as the independent variable while Price to Book Value is the dependent variable (Sugiyono, 2018  Price to Book Value. This is because investment is not fully measured by asset growth but is based on potential profits.

Research Hypothesis Test
A prerequisite analysis test was carried out to test the research hypothesis, including normality and linearity tests. The test results are shown as follows:

Hypothesis Testing with Simple Linear Regression
After testing the analysis prerequisites, a simple linear regression test was conducted to test the research hypothesis. This test involves several statistical calculations, such as significance test (t-test), ANOVA, and hypothesis determination. The simple linear regression analysis involved a regression equation that describes the predictive function of the variables affecting other variables (Rusiadi & Hidayat, 2013). Tables 5 and 6 show the linear regression test results between TAG and PBV. The simple linear regression test results in Table 5 have a value of 0.890, indicating that H0 is accepted. Therefore, Total Asset Growth has no significant effect on Price to Book Value on the Jakarta Islamic Index (JII). This result contradicts the statement that TAG could measure the growth of company assets within a certain period (Rahmanto, 2017). TAG is the ratio between the current and previous total assets of the company to determine investment decisions. According to Zulvia (2019), Devianasari and Suryantini (2015), also Indari (2018), investment should not be measured by asset growth but by profit development as the main consideration for investors. Therefore, the regression analysis confirms that TAG does not affect PBV. Based on the statistical analysis in Table 5, H is accepted, and H is rejected. o a  The R square value in Table 7 shows the strong effect of TAG on PBV. The analysis shows a value of 0.004, or a percentage of 4% on PBV, meaning that H0 is accepted and Ha is rejected. Therefore, there is no effect of TAG on PBV.
Investors would continue to invest in the company, even when assets are experiencing a decrease due to the probability that the assets may increase in the future. This supports Hartono (2015), which stated that when the company's assets decrease, there is no certainty certain that they may decrease in the future. An example is PT. Unilever Tbk, with the company code UNVR. The TAG value decreased by 0.04 between 2015 and 2016 (from 0.01 to 0.06), while PBV increased by 0.89. This implies no direct relationship between TAG values towards PBV, and a decreasing value indicates a decrease in the company's assets. It could be caused by a debt payment or the purchase of new assets (Devianasari & Suryantini, 2015). These conditions are not detrimental to the company, and investors would still invest.
TAG attracts investors as an offer that the company's assets would continue to grow (Mukhlis, 2017). This could be caused by the value that exceeds the investment capital provided. A decreasing value is not always bad for investors because they consider other assets in the company, such as production locations and movable assets. For this reason, companies with low TAG still attract investors (Salsabila & Ryandono, 2020;Indari, 2018). This could be due to other factors, and investors believe that the company's asset value would increase over time (Hakim, 2020;Wijayanti et al., 2016 This is supported by Rahmah and Asnawi (2019) and Annisa and Chabachib (2017) that the Total Asset Growth could be small but still affect the company's value on the stock market.
It attracts investors to guarantee a company's future (Nasution, Putri, & Dungga, 2018;Hafifah & Fitriany, 2012), even when it has a small value. Therefore, investors find it attractive, hoping that the company keeps developing, as reflected in financial books.
Total Asset Growth symbolizes a company's prosperity in the stock development (Hartono, 2015) and describes an implication of profits. However, investors also consider their survival in times of crisis with significant TAG growth (Salsabila & Ryandhono, 2020). An example was during the beginning of the pandemic when the stock market decreased and even sold to stabilize the company (Widyakto & Ariefiantoro, 2020). Therefore, when purchasing Price to Book Value, investors no longer focus only on Total Asset Growth but also on the potential profits.

CONCLUSION
This research shows that the Total Asset Growth variable does not significantly affect the Price to Book Value of companies in the Jakarta Islamic Index in the 2014-2020 period. This is because investment is not fully measured by asset growth but is based on the potential profits for investors. Furthermore, a decreasing TAG value is not always bad for investors. Therefore, they should not rely on TAG in making investments but consider other assets in the company.
However, this research has not described its condition during the Covid-19 pandemic. This is because the data provided by the Indonesia Stock Exchange (IDX) did not fully summarize the current stock market conditions. Therefore, further research should examine the development of TAG on PBV during the Covid-19 pandemic. This would serve as a reference for investors in making PBV purchasing decisions during a pandemic.
