ANALISIS PENGARUH BETA, SIZE, BOOK TO MARKET, DAN PROFITABILITY TERHADAP RETURN AGGRESIVE STOCK (Studi Kasus Pada Indeks Saham Kompas 100 Pada Pasar Modal Indonesia Periode 2009 – 2013)

Aggressive stocks are stocks that have a high degree of volatility and risk in which this stock has a beta values above one. Which means that stock will increase rapidly if the state of the market has increased, and decreased sharply when the state of the market decline. This study aims to examine the influence of beta, size, market to book ratio, and profitability against aggressive stock return. The sample used in the study were 15 companies listed in the Indonesia Stock Exchange (BEI), are included in the index are konsiten Compass 100, in the period 2009 to 2013, and has a high beta value of shares (β> 1). The sampling method used in this research is purposive sampling. The analysis technique used in this study is multiple regression, classic assumption test, normality test, multicollinearity, heteroscedasticity test, autocorrelation test, test the coefficient of determination (adjusted R2), the F statistic test, and t statistical test . These results indicate that beta stocks have a positive and significant impact on aggressive stock returns. Variable size has a negative and significant impact on the variable aggressive stock return. However, there was no significant influence between the variables of market to book ratio and return on equity on stock returns aggressiv

Land of Addicts? An Empirical Investigation of Habit-Based Asset Pricing Models

A popular explanation of aggregate stock market behavior suggests that assets are priced as if there were a representative investor whose utility is a power function of the difference between aggregate consumption and a “habit” level, where the habit is some function of lagged and (possibly) contemporaneous consumption. But theory does not provide precise guidelines about the parametric functional relationship between the habit and aggregate consumption. This makes for- mal estimation and testing challenging; at the same time, it raises an empirical question about the functional form of the habit that best explains asset pricing data. This paper studies the ability of a general class of habit-based asset pricing models to match the conditional moment restrictions implied by asset pricing theory. Our approach is to treat the functional form of the habit as unknown, and to estimate it along with the rest of the model’s finite dimensional parameters. This semiparametric approach allows us to empirically evaluate a number of interesting hypotheses about the specification of habit-based asset pricing models. Using stationary quarterly data on consumption growth, assets returns and instruments, our empirical results indicate that the estimated habit function is nonlinear, the habit formation is internal, and the estimated time-preference parameter and the power utility parameter are sensible. In addition, our estimated habit function generates a positive stochastic discount factor (SDF) proxy and performs well in explaining cross-sectional stock return data. We find that an internal habit SDF proxy can explain a cross-section of size and book-market sorted portfolio equity returns better than (i) the Fama and French (1993) three-factor model, (ii) the Lettau and Ludvigson (2001b) scaled consumption CAPM model, (iii) an external habit SDF proxy, (iv) the classic CAPM, and (v) the classic consumption CAPM

Development of an experimental platform for the investigation of laser-plasma interaction in conditions relevant to shock ignition regime

The shock ignition (SI) approach to inertial confinement fusion is a promising scheme for achieving energy production by nuclear fusion. SI relies on using a high intensity laser pulse (≈1016 W/cm2, with a duration of several hundred ps) at the end of the fuel compression stage. However, during laser-plasma interaction (LPI), several parametric instabilities, such as stimulated Raman scattering and two plasmon decay, nonlinearly generate hot electrons (HEs). The whole behavior of HE under SI conditions, including their generation, transport, and final absorption, is still unclear and needs further experimental investigation. This paper focuses on the development of an experimental platform for SI-related experiments, which simultaneously makes use of multiple diagnostics to characterize LPI and HE generation, transport, and energy deposition. Such diagnostics include optical spectrometers, streaked optical shadowgraph, an x-ray pinhole camera, a two-dimensional x-ray imager, a Cu Kα line spectrometer, two hot-electron spectrometers, a hard x-ray (bremsstrahlung) detector, and a streaked optical pyrometer. Diagnostics successfully operated simultaneously in single-shot mode, revealing the features of HEs under SI-relevant conditions.T. Tamagawa, Y. Hironaka, K. Kawasaki, D. Tanaka, T. Idesaka, N.

Analysis Of Causality Exchange Rate and Export Value In Indonesia (Empirical Study in 1997-2020)

This study aims to analyze the causal relationship between the exchange rate and export value in Indonesia using time series data from 1997 to 2020. The analytical method that will be used in this research is the Granger Causality Test approach. The instruments used are the data normality test, the stationary test, the optimal lag test, and the Granger causality test. Based on the results of the research that has been done, it shows that from the output of the cointegration test in table 4.3 above, the trace statistic is 9.016078, which is smaller than the critical value (5%), which is 15.49471, and Prob. 0.3639 is less than 5 percent, whereas for the output of the Granger causality test above, at lag 1, it is known that the probability value (Prob.) of the relationship between export value and exchange rate is 0.4953; this result is greater than the significance level of 5 percent, so that from the output of the From these results, it can be concluded that there is no causal relationship between export values and exchange rates. So it can be concluded that if the exchange rate depreciates against foreign currencies, the export value will increase because Indonesia's export commodities compete in international markets, but on the contrary, it will reduce. In addition, based on observations and causality analysis from the results of data processing, it shows that there has been a one-way relationship between the exchange rate and the export value, meaning that the exchange rate will affect the export value but will, on the contrary, affect the export value. According to the results of the Granger Causality Test, the export value has no effect on the exchange rate

Proof-of-principle experiment for laser-driven cold neutron source

The scientific and technical advances continue to support novel discoveries by allowing scientists to acquire new insights into the structure and properties of matter using new tools and sources. Notably, neutrons are among the most valuable sources in providing such a capability. At the Institute of Laser Engineering, Osaka, the first steps are taken towards the development of a table-top laser-driven neutron source, capable of producing a wide range of energies with high brightness and temporal resolution. By employing a pure hydrogen moderator, maintained at cryogenic temperature, a cold neutron ($$\le 25\hbox { meV}$$≤25meV) flux of $$\sim 2\times 10^3\hbox { n/cm}^2$$∼2×103n/cm2/pulse was measured at the proximity of the moderator exit surface. The beam duration of hundreds of ns to tens of \upmu \hbox {s}μsis evaluated for neutron energies ranging from 100s keV down to meV via Monte-Carlo techniques. Presently, with the upcoming J-EPoCH high repetition rate laser at Osaka University, a cold neutron flux in orders of $$\sim 1\times 10^{9}\hbox { n/cm}^2/\hbox {s}$$∼1×109n/cm2/sis expected to be delivered at the moderator in a compact beamline
