"This paper empirically examines the efficient market hypothesis (EMH) in the Islamic stock market
namely Jakarta Islamic Index by emphasizing on the random walk behavior and nonlinearity. In
the first step, we employ Brock et al. (1996) test to examine the presence of nonlinear behavior in
Jakarta Islamic Index. The evidence of nonlinear behavior in the indices, motivate us to use nonlinear
ESTAR unit root test procedure recently developed by Kapetanios et al. (2003) and Kruse (2011).
The nonlinear unit root test procedure fail to rejects the null hypothesis of unit root for the indices,
suggesting that Jakarta Islamic Index characterized by random walk process supporting the theory
of efficient market hypothesis. In addition, Lumsdaine and Papel (LP) test identified significant structural
breaks in the index series."

"Konsep Fractal Market Hypothesis (FMH) dalam pasar modal muncul sebagai alternatif teori Efficient Market Hypothesis (EMH) yang mampu menunjukkan kelemahan teori portofolio modern yang mengasumsikan bahwa investor bersifat rasional, pasar efisien, dan random walk. Fraktal mempunyai karakteristik yang tidak random, melainkan memiliki pola. Fraktal mengalami perulangan pola atau struktur dengan skala dan ukuran yang berbeda, dan menunjukkan adanya trend. Penelitian ini merupakan studi empiris yang bertujuan untuk mengetahui apakah konsep fraktal berlaku terhadap return harian indeks LQ45 dan lima saham perbankan yang bertahan dalam kelompok LQ45 selama periode 2 Juni 2008 sampai dengan 1 September 2009. Dalam penelitian digunakan analisis Rescaled Range (R/S) dan nilai eksponen Hurst (H) untuk melihat karakteristik pergerakan return, mengukur tingkat risiko, mengukur korelasi dan melihat dimensi fraktal. Berdasarkan hasil penelitian dapat disimpulkan bahwa pergerakan harga return harian indeks LQ45 dan lima saham perbankan kelompok LQ45 di BEI lebih mendekati asumsi FMH dengan konsep bias random walk, investor terdiri dari berbagai horison investasi dan pergerakan return saham dari waktu ke waktu mempunyai keterkaitan.

Fractal Market Hypothesis (FMH) turns up in the capital market as an alternative theory for Efficient Market Hypothesis (EMH). The EMH assumes that investor have rational character, efficient market and random walk. This study is an empirical study to identify whether the EMH concept is still suitable for the LQ45 stocks return or applies to the Hurst process which is biased random walk in nature and which is in accordance with the FMH concept emphasizing the effect of the liquidity and the horizon of the investor behavior. FMH concept uses Rescaled Range analysis as a statistical processing tool and Hurst value used to measure the degree of risk. The result of this study shows that the FMH assumptions are more realistic than the EMH assumptions and do happen on the Indonesian Capital Market, especially for LQ45."

"Tesis ini membahas gejala overreaction di Bursa Efek Indonesia secara khusus terhadap 38 saham sektor industri dasar dan kimia selama periode 2006-2011. Metode yang digunakan adalah metode komparatif antara portofolio winner dan loser. Periode penelitian dibagi menjadi 2, yaitu 6 bulan dan 12 bulan.
Penelitian ini menemukan beberapa gejala overreaction, baik pada observasi 6 bulan maupun 12 bulan, namun secara statistik tidak signifikan. Selain itu juga ditemukan bahwa gejala overreaction bersifat asimetris, yaitu lebih terlihat pada salah satu portofolio.
Hasil penelitian menunjukkan Bursa Efek Indonesia efisien dalam bentuk lemah, sehingga penerapan strategi kontrarian diperkirakan akan merugikan untuk diterapkan pada segmen pasar ini.

Penelitian ini menguji pengaruh dari keterbukaan perdagangan dan keterbukaan finansial terhadap efisiensi informasi pasar saham di negara-negara ASEAN. Penelitian ini menggunakan sampel lima 5 negara dengan pasar saham paling mapan di ASEAN - Indonesia, Malaysia, Filipina, Singapura, dan Thailand. Dalam melakukan pengujian, peneliti menggunakan data panel. Hasil dari penelitian ini menunjukkan bahwa saat Singapura dikeluarkan dari sampel, keterbukaan perdagangan de facto memiliki dampak negatif terhadap efisiensi efisiensi informasi pasar saham, sedangkan keterbukaan finansial de facto memiliki dampak positif terhadap efisiensi informasi pasar saham. Pengukuran de jure atas keterbukaan perdagangan terbukti tidak memiliki pengaruh signifikan terhadap efisiensi informasi.

Penelitian ini bertujuan untuk melihat apakah terdapat mispricing pada saham syariah di empat negara anggota ASEAN, yaitu Indonesia, Malaysia, Singapura dan Thailand. Penelitian dilakukan dengan menggunakan Three-factor Asset Pricing Model oleh Fama dan French 1993 dengan data harga saham harian yang kemudian diagregasi ke dalam 25 portofolio saham yang disusun berdasarkan size dan book-to-market equity. Penelitian ini menemukan bahwa saham syariah di Indonesia dan Malaysia cenderung efisien karena tidak terdeteksi keberadaan mispricing pada kedua negara tersebut, sedangkan terdeteksi mispricing yang signifikan di Thailand dan mispricing yang marginally significant pada saham syariah di Singapura sehingga kedua pasar saham syariah tersebut terindikasi tidak efisien. Selain itu, krisis keuangan 2008 memiliki pengaruh terhadap keberadaan mispricing dan efisiensi pada pasar saham syariah di Indonesia dan Thailand. Penelitian ini melengkapi penelitian-penelitan efisiensi pada saham syariah karena menggunakan sampel yang belum pernah diteliti sebelumnya, yaitu saham syariah di ASEAN yang mayoritasnya merupakan emerging markets dan menggunakan data harian pada level individual saham bukan indeks.

"Penelitian ini secara empiris menguji Hipotesis Pasar Adaptif pada pasar saham Asia Tenggara dengan menguji tingkat prediktabilitas return menggunakan data indeks penutupan harian selama 30 tahun periode penelitian, mulai Januari 1988 s.d. Desember 2017. Penelitian ini menggunakan tiga versi bootstrap dari Variance Ratio Test pada return index, yaitu Chow Denning Test (1993) dan Joint Sign and Joint Rank Test oleh Wright (2000). Lebih lanjut, penelitian ini juga mengkaji tingkat prediktabilitas return dengan menggunakan moving windows secara bulanan dan juga menguji hubungan antara tingkat prediktabilitas return dengan kondisi pasar. Hasil penelitian menunjukkan bahwa ada periode yang memiliki tingkat pengembalian yang dapat diprediksi, tetapi ada juga periode yang tidak memiliki tingkat pengembalian yang dapat diprediksi. Riset juga membuktikan bahwa kondisi pasar memiliki korelasi dengan prediktabilitas return, namun demikian setiap pasar saham bereaksi berbeda terhadap kondisi pasar tertentu. Oleh karena itu, penelitian ini menunjukkan hasil yang sejalan dengan Hipotesis Pasar Adaptif dan bahwa setiap pasar saham beradaptasi secara berbeda terhadap kondisi pasar tertentu. Implikasinya, penelitian ini menyarankan agar investor melihat masing-masing pasar saham secara independen karena masing-masing pasar memiliki tingkat prediktabilitas return yang berbeda dan juga tingkat korelasi yang berbeda dengan kondisi pasar.
......This study empirically tests the Adaptive Market Hypothesis on the Southeast Asian stock market by testing the return predictability using daily closing index data for 30 years of the study period, from January 1988 s.d. December 2017. This study uses three bootstrap versions of the Variance Ratio Test on the return index, namely the Chow Denning Test (1993) and the Joint Sign and Joint Rank Test by Wright (2000). Furthermore, this study also examines the level of return predictability by using moving windows on a monthly basis and also examines the relationship between the level of return predictability and market conditions. The results show that there are periods that have a predictable rate of return, but there are also periods that have no predictable rate of return. Research also proves that market conditions have a correlation with the predictability of returns, however, every stock market reacts differently to certain market conditions. Therefore, this study shows results that are in line with the Adaptive Market Hypothesis and that each stock market adapts differently to certain market conditions. The implication, this research suggests that investors look at each stock market independently because each market has a different level of return predictability and also a different level of correlation with market conditions."

"ABSTRAK
We use a generalized autoregressive conditional heteroskedasticity dummy approach
to analyze the influence of calendar anomalies on conditional daily returns and risk
for the stock markets of Brazil, Russia, India, China, and South Africa from 1996 to
2018. Month-of-the-year, turn-of-the-month, day-of-the-week, and holiday effects are
investigated. The most striking day-of-the-week effect is found for Tuesdays. The turn-
of-the-month effect is validated, while, interestingly, we find no evidence of a January
effect. A general holiday effect is not documented, but the Indian market shows a
significant pre- and post-holiday effect, the Chinese market is anomalous before public
holidays, and the South African market is affected only after holidays."

"This paper investigated the impact of seasoned equity offerings (SEO) on stock return of listed
companies in Ho Chi Minh City market using the method “event study” which has been basically
formed by Campbell, Lo, and MacKinlay (1997). The sample includes 332 SEOs from 2007 to 2010.
The main findings show evidence that the Ho Chi Minh City market was not efficient in terms of the
semi-strong form because the price has increased significantly on the ex-right date, day 0. In an opposite
way, the market also reacted significantly negatively from T-4 to T-2. There are some significant
impacts of timing on issue methods – equity right issues were in priority for favorable time and issues
as “dividend by stocks” were chosen during unfavorable time."
