Abstract

Penelitian ini dilatarbelakangi oleh fenomena peningkatan partisipasi investor ritel di era digital serta meningkatnya ketidakpastian ekonomi global yang mempengaruhi dinamika pasar modal. Penelitian ini bertujuan untuk menganalisis pengaruh aspek perilaku keuangan (behavioral finance) yang diproksikan dengan investor attention dan aspek makroekonomi global yang diproksikan dengan US Economic Policy Uncertainty (US EPU) terhadap kinerja pasar saham, yaitu stock return dan stock liquidity. Unit analisis dalam penelitian ini adalah perusahaan perbankan kategori Kelompok Bank Modal Inti (KBMI) 4 yang terdaftar di Bursa Efek Indonesia (BEI), yang dipilih karena memiliki kapitalisasi pasar terbesar dan likuiditas tinggi. Penelitian ini menggunakan pendekatan kuantitatif dengan data sekunder harian. Teknik analisis data yang digunakan adalah regresi data panel dengan estimasi model terbaik Fixed Effect Model (FEM) yang telah dikoreksi menggunakan Robust Standard Error (White) untuk mengatasi masalah heteroskedastisitas. Pengujian hipotesis dilakukan untuk melihat pengaruh parsial dan simultan dari variabel independen terhadap variabel dependen. Hasil penelitian menunjukkan temuan empiris yang beragam. Pertama, investor attention diprosikan dengan Google Search Volume Index (GSVI) berpengaruh negatif dan signifikan terhadap stock return, yang mengindikasikan bahwa lonjakan pencarian informasi dimaknai pasar sebagai sinyal risiko (signaling risk) akibat asimetri informasi, sehingga memicu tekanan jual. Kedua, investor attention berpengaruh positif dan signifikan terhadap stock liquidity, membuktikan bahwa penyebaran informasi mampu mendorong partisipasi pasar. Ketiga, US EPU tidak berpengaruh signifikan terhadap stock return, yang menunjukkan tingginya resiliensi fundamental perbankan Indonesia terhadap isu global. Keempat, US EPU berpengaruh negatif dan signifikan terhadap stock liquidity akibat perilaku wait and see investor. Penelitian ini merekomendasikan agar investor lebih rasional dalam menyaring informasi digital agar tidak terjebak kepanikan sesaat, serta menyarankan regulator untuk memantau sentimen digital sebagai indikator dini volatilitas pasar. ***** This research is motivated by the phenomenon of increasing retail investor participation in the digital era and rising global economic uncertainty affecting capital market dynamics. This study aims to analyze the influence of behavioral finance aspects proxied by investor attention and global macroeconomic aspects proxied by US Economic Policy Uncertainty (US EPU) on stock market performance, specifically stock return and stock liquidity. The unit of analysis in this study is the banking companies under the Core Capital Bank Group (KBMI) 4 category listed on the Indonesia Stock Exchange (IDX), selected due to their largest market capitalization and high liquidity. This study employs a quantitative approach using daily secondary data. The data analysis technique used is panel data regression with the Fixed Effect Model (FEM) estimation, corrected using Robust Standard Error (White) to address heteroscedasticity issues. Hypothesis testing was conducted to observe the partial and simultaneous effects of independent variables on dependent variables. The results reveal diverse empirical findings. First, investor attention proxied by Google Search Volume Index (GSVI) has a negative and significant effect on stock return, indicating that a surge in information search is interpreted by the market as a risk signal due to information asymmetry, thereby triggering selling pressure. Second, investor attention has a positive and significant effect on stock liquidity, proving that information dissemination can encourage market participation. Third, US EPU does not have a significant effect on stock return, demonstrating the high resilience of Indonesia's banking fundamentals against global issues. Fourth, US EPU has a negative and significant effect on stock liquidity due to investors' wait-and-see behavior. This study recommends that investors be more rational in filtering digital information to avoid momentary panic, and suggests that regulators monitor digital sentiment as an early indicator of market volatility.
