Introduction
Most research shows that inflation has a significant impact on stock returns.Whether the impact is positive or negative, however, is a matter of much debate.Chen et al (2005) concluded that inflation cannot predict stock returns.According to Tripathi and Kumar (2014), the relationship between inflation and stock returns in BRICS is contradictory, with Russia showing a significant negative relationship, while India and China show a significant positive relationship.Priyono, (2016Priyono, ( , 2018Priyono, ( , 2019)), Priyono, Briyan Cadalora Putra Cisa Cadalora Putri, (2019), states that there are two traditional peak annual inflation in Indonesia.The December-January period always brings higher prices due to Christmas and New Year celebrations, while traditional flooding in January (in the middle of the rainy season) results in disruption of distribution channels in several regions and cities, resulting in higher logistical costs.The second peak of inflation occurred in the July-August period.Inflationary pressure in these two months came as a result of holidays, Muslim holy fasting month, Eid al-Fitr and the beginning of the new school year.Significant improvements can be detected in expenditures on food and other consumables (such as clothing, bags and shoes), along with retailers who adjust prices upwards.
From the research results of Priyono, Briyan Cadalora Putra Cisa Cadalora Putri , (2016, 2018, 2019), it was stated that the social implications of policy makers could apply empirical evidence in the time series as a theoretical foundation while establishing fiscal, monetary or exchange rate policies to stabilize output and employment opportunities using interest rates, the amount money supply, and exchange rates in other cities.Abedallat and Shabib (2012) studied the impact of macroeconomic indicators such as changes in investment and gross domestic product (GDP) as independent variables and the movement of the Amman Stock Exchange index as the dependent variable for the 1990-2009 data period.They found the relationship between the two macroeconomic indicators (investment and GDP) and the Amman Stock Exchange index, and also between each separately and the stock index, which means that price movements on the Amman Stock Exchange are influenced by the movements of these two variables, and there are influences both of these variables towards the Amman Stock Exchange index movement.Furthermore, they found the impact of investment changes was greater than the impact of changes in GDP on the Amman Stock Exchange index.Gunsel and Cukur (2007) analysis the effect of macroeconomic factors on London stock returns for the period between 1980 and 1993.They developed seven predetermined macroeconomic variables.The term structure of interest rates, risk premiums, exchange rates, money supply, and unanticipated inflation, sectoral dividend yields and sectoral unexpected production are used as independent variables and returns on London shares as the dependent variable.The results show that macroeconomic factors have a significant influence on the UK stock market but; each factor can affect different industries in different ways.That is, macroeconomic factors can affect one industry positively, but negatively affect other industries Interest rates are defined as the price of money.This is the proportion of loan funds demanded by investors for the use of these funds.Many governments use interest rates as a monetary policy tool to control other macroeconomic variables such as investment, inflation and unemployment.Alam and Uddin (2009) found that interest rates have a significant negative relationship with stock prices for 15 developed and developing countries using data from 1988 to March 2003.According to Humpe and Macmillan (2007), stock prices are negatively correlated with the long term interest rates in the US and Japan.
The stock market is very important in the economic development of an economy given its role as an intermediary between borrowers and lenders.The stock market is very important in Indonesia mobilizing long-term capital to listed companies by collecting funds from different investors to enable them to expand their business, and offering investors alternative investment paths to enter their surplus funds.In addition, the level of economic stock market development is the main factor in determining overall financial development and sustainability (Ashaolu & Ogunmuyiwa, 2010).A well-functioning stock market contributes to economic development through more efficient allocation of resources and increasing savings (Junkin, 2012).
Previous studies concluded that changes in stock prices are related to macroeconomic factors.According to Liu and Shrestha (2008), a country's macroeconomic activity has an effect on stock market returns.Muradoglu et al (2000) show that changes in stock prices are related to macroeconomic behavior in developed countries.The Arbitrage Price Theory (APT) championed by Stephen Ross (1976) also provides a theoretical framework for the relationship between stock prices and macroeconomic fundamentals by modeling them into linear functions in which sensitivity to changes in each factor is represented by beta-specific factors.Stock prices, therefore stock returns are generally believed to be determined by some fundamental macroeconomic variables such as interest rates, inflation, exchange rates, and Gross Domestic Product (Kirui, Wawire and Ono, 2014).
From some of the studies above the authors are interested in analyzing themed studies: The Effect Of Macro Economic Variables On Stock Return Of Companies That Listed In Stock Exchange : Empirical Evidence From Indonesia.
Furthermore, this study can be formulated as the following hypothesis: 1.It is assumed that the inflation rate has an effect on Stock Return 2. It is assumed that the interest rate has an effect on Stock Return 3. Suspected money supply has an effect on Stock Return 4. Exchange rate is expected to have an effect on Stock Return

Data and Sample
The study used macroeconomic data reported online by related institutions such as Indonesian banks, Indonesia Stock Exchange, Central Bureau of Statistics, and others.The macroeconomic data used consisted of the inflation rate, the average interest rate prevailing in the bank at the time of observation, the amount of money in circulation, the development of the foreign exchange or the US dollar against the value of the IDR, and the development of the overall stock return of listed companies in the Exchange Effect Indonesia.
This study uses monthly time series data from November 2016 to June 2018 or 20 months of observation.The reason for using this timeframe is mainly to explain the current phenomenon which can be explained in the previous few months, since using long-term data several years earlier is less realistic than the short monthly period as conducted in this study.

Variable Measurement
Variable used in this study consisted of the dependent variable of the overall return rate of firms in Indonesia Stock Exchange, and four independent variables consisting of inflation rate, interest rate, amount of money in circulation, and US dollar exchange rate against rupiah value, as stated below .
(a) The dependent variable of the company's stock return rate (YR i ) as a whole company listed on the Indonesia Stock Exchange, in proxy by using the composite stock price index or JCI between the time that is the growth rate

Descr
The struc namely:  between variables is smaller than 1%, which means that the hypothesis proposed in this study has been appropriate and supported by the calculation of statistical test t.

Discussion
Based on hypothesis as it is evidenced on the results calculation statistic and pay attention results research earlier as put forward before, then need discussed some p Relevant principal with the role of macro variables economy in influence stock return whole companies in Indonesia Stock Exchange, namely : (a) Hypothesis about the effect of macroeconomic variables made from inflation rate, interest rate , amount money outstanding, and currency foreign proven take effect significant to stock return whole companies in the Indonesian Stock Exchange.It is in line with hypothesis above and relevant with results research earlier as it is findings reported at Chen et al (2005), Gunsel & Cukur (2007), Abedallat & Shabib (2012).
(b) Research this find that in period short and medium, it turns out level inflation take effect positive against stock return company.It is happen because support of government as it is done moment this to development industry and business world, have an impact to enhancement chance work or push number poverty.Because of unemployment decreased, then as it is Philips theory proves that inflation negative compared with unemployment, because happen enhancement spending consumption home stairs and triggers enhancement inflation, so otherwise when unemployment increased then inflation decrease because community experience difficulty finance and demand decrease although price tend more cheap.The implication, which is inflation is relatively controlled push increase in stock return, so required ethers money policy of the Central Bank and fiscal policies by the government for inflation located position control.The results of this study support the research results of Priyono, (2016Priyono, ( , 2018Priyono, ( , 2019)), Priyono, Briyan Cadalora Putra Cisa Cadalora Putri, (2019) (c) Implications of interest policy is authority monetary have the role of macroeconomic variable this no impact bad to development of a marked business world with declining stock returns company.Variable interest rate have a negative effect on stock return because with increased interest will push amount investment of industry and business sector, and this means also will improve amount unemployment and pushing growth number poverty.This is where role authority monetary for on wise in use interest rate reference that can influence the bank interest overall.
The results of the study this in line with theory investment, which states that interest rate negatively correlated with investment, or investment is function from interest rate and have a slope or a negative curve, which means that on the interest rate high will cause decline amount investment, otherwise of low interest will push growth investment.If investment experience increase, then the business world increasingly growing, the amount unemployment down, numbers poverty increasingly low, and stock returns company tend experience improvement.this is in line with the opinion: Priyono, Briyan Cadalora Putra Cisa Cadalora Putri, (2019) (d) amount money outstanding impact positive against stock return, inside period short and long term medium happen growth opportunities business because banking push enhancement funding investment industry and business world, so performance finance company increasingly increase.Enhancement profitability or performance finance industry and business world, and convenience earn funding banking push increase of stock return companies in the Stock Exchange.Implications policy of banking , that is push interest community in optimizing use its revenue, through various policy amenities credit so transaction business increased because community chance use future income for used this moment.
(e) The exchange rate currency foreign have a negative and significant effect against stock return companies in the Securities Exchange are meaningful that point a weakening exchange will cause loss company certain such as : the company that owns debt overseas or debt with value currency foreign, using ingredients default from abroad, imports capital goods, and others.The implication, that investors in the Stock Exchange respond value exchange currency foreign because in general increase value currency foreign, will pressing stock return company on overall characterized with decline index price stock Composite Indonesia Stock Exchange.

Conclusion and Suggestion
The results of the study this concluded: (a) In period short and medium, inflation rate take effect positive and significant to stock return of companies on the Indonesia Stock Exchange, which means that increase inflation push increase price stock company.Suggested for monetary policy by central banks and fiscal policies by the government control inflation, because level of inflation the give signal positive for investors in the capital market, so push taking investor decisions within determine its investment portfolio in the Capital Market.
(b) interest rate have a negative and significant effect to stock return of companies on the Indonesia Stock Exchange, which means that increase interest rate push price stock companies in the Stock Exchange.Suggested for monetary policy to interest rate reference do with take into account the impact to macroeconomic, because that policy very sensitive to investor decisions in the capital market, even in form information about plan increase interest rate reference will trigger movement price shares in the Stock Exchange.
(c) Numbers money outstanding take effect positive and significant to stock return of companies on the Indonesia Stock Exchange, which means that increase amount money outstanding will push increase price stock companies in the Stock Exchange.It is suggested that the central bank control amount money outstanding, due to macroeconomic variables this significant influence against stock return of company on the Stock Exchange, and if this ignored, then impact multiplier will happen on systemic in resonance national level.
(d) Exchange currency foreign have a negative and significant effect to stock return of companies on the Indonesia Stock Exchange, which means that increase value exchange currency foreign will impact to decline price shares in the Stock Exchange.It is suggested that the government control balance sheet transaction walk through share policy such as: push enhancement export, limit import goods consumptive, supervising and controlling debt outside undertaken by the government, state-owned and private cause deficit balance sheet transaction walking .

Implication
Implications for research next is could do research similar with expand period range time for example 5 to 10 years, and use additional macroeconomic variables others that have not used in this study, so could complete this research.
