The result is that, all of those three methods prove that momentum strategy is effectively applicable for winner stock, so in the next period winner stock will continue to make profit, while for loser stock, it is more effective to use contrarian strategy because in the next period, loser stock will rebound and make profit after suffering from high loss."

"Penelitian ini membahas tentang terjadinya disposition effect dan pengaruhnya terhadap momentum saham di Indonesia. Disposition effect adalah kecenderungan investor untuk menjual saham winners terlalu cepat dan menahan saham losers terlalu lama. Momentum adalah salah satu anomali yang diamati di asset pricing, di mana return saham selalu berkelanjutan selama tiga hingga 12 bulan (jika positif, akan terus positif, jika negatif, akan terus negatif selama rentang waktu tersebut). Penelitian ini menggunakan data transaksi harian investor 30 security broker di Bursa Efek Indonesia dan data saham LQ45 selama tahun 2010-2013. Hasil dari penelitian ini membuktikan keberadaan disposition effect pada para investor dari 30 security brokers di Indonesia dan bahwa momentum tidak terdapat di Indonesia. Ketidakberadaan momentum ini dapat disebabkan oleh pemilihan saham yang likuid, karena saham yang likuid cenderung efisien.

This paper analyses behavioral finance phenomenon known as disposition effect and its impact on stock momentum in Indonesia. Disposition effect is investor's tendency to sell winning stocks too early and hold losing stocks too long. Momentum is one of the anomalies observed in asset pricing, where stock return is continuous for three to twelve months (if the return is positive, it will keep on being positive, and vice versa). This research uses daily transaction data of 30 security brokers investors at Indonesian Stock Exchange and daily data of LQ45 stocks in Indonesia for the years 2010-2013. The results prove that disposition effect occurs in 30 largest security brokers Indonesia and that momentum does not exist in Indonesia. Liquid stocks chosen as sample could affect this finding because liquid stocks tend to be efficient."

"Tujuan utama tesis ini adalah untuk mengetahui pola perdagangan saham intrahari ditinjau dari return dan volatilitasnya, mengetahui adanya day of the week effect dan time of the day effect serta melihat perbedaan return antar hari perdagangan dan antar interval waktu 30 menit pada 5 fraksi perdagangan di Bursa Efek Indonesia. Hasil penelitian ini menunjukkan bahwa return kelima kelompok fraksi perdagangan membentuk kurva yang tidak seragam. Return kelompok fraksi perdagangan Rp1 membentuk kurva W, kelompok fraksi perdagangan Rp5, Rp10 dan Rp25 membentuk kurva J sedangkan kelompok fraksi perdagangan Rp50 membentuk kurva U. Ditinjau dari volatilitasnya, kelima kelompok fraksi perdagangan membentuk kurva yang sama yaitu kurva U. Dengan adanya perbedaan pola perdagangan ini maka investor dapat menetapkan strategi investasi yang tepat yaitu waktu terbaik untuk melakukan transaksi (buy/sell) dan kelompok fraksi saham yang direkomendasi dan yang dihindari. Selain itu penelitian ini juga membuktikan adanya pengaruh signifikan dari pergerakan return saham baik berdasarkan periode hari maupun interval waktu 30 menit terhadap return saham. Dengan demikian hal ini membuktikan adanya day of the week effect dan time of the day effect pada semua kelompok fraksi perdagangan.

The main objective of this thesis is to determine stocks Intraday trading patterns in terms of returns and volatility by examining the day of the week effect and time of the day effect as well as investigating the return difference among trading days and among interval of 30 minutes for 5 fractions of trading in the Indonesia Stock Exchange.

The results indicate the return curves of the five trade fractions group are not similar. The returns of trade fraction group Rp1 form W-curve, trade faction group Rp5, Rp10 and Rp25 form J-curve, while trade fraction group Rp50 form the U-curve. However, the volatility of the five groups forms identical curve that is U-curve. By taking into account the differences in the pattern of trade, investor can determine proper investment strategy that is the best time to do the transaction (buy/sell) and the fraction of shares that are recommended and which to avoid.

In addition, this study demonstrates the existence of significant influence from either the movement of stock returns based on the period of the day and 30-minute intervals of stock return. Thus, the evidence supports the existence of day of the week effect and time of the day effect on all groups of trading fraction. The findings show the existence of significant return differences either between day trading and inter-interval time of 30 minutes."

"Penelitian ini menganalisis apakah penggunaan informasi yang saling berkaitan dalam revenue surprise, earnings surprise, dan prior returns dapat memberikan nilai tambah kepada penerapan strategi investasi di Bursa Efek Indonesia selama periode tahun 2001-2012. Penelitian ini juga secara tidak langsung melakukan pengujian terhadap keberadaan fenomena momentum harga dan post-earnings-announcement drift. Hasil penelitian ini menunjukkan bahwa investor cenderung bereaksi kurang terhadap informasi kinerja fundamental, namun sebaliknya bereaksi berlebihan terhadap informasi kinerja pasar 6 bulan sebelumnya. Hal tersebut terlihat dari penerapan strategi momentum pendapatan dan laba yang efektif, namun tidak dengan strategi momentum harga. Pengujian dominasi strategi menunjukkan bahwa terdapat kontribusi profit yang independen satu sama lain, dan kontribusi profit ini tetap signifikan setelah dilakukan penyesuaian terhadap CAPM dan model 3 faktor Fama-French. Penerapan strategi multivariat terbukti memberikan tambahan return yang positif dan signifikan. Hal ini mengindikasikan bahwa setiap informasi memiliki konten eksklusif yang tidak dihargai oleh pasar dan investor cenderung kurang mempertimbangkan implikasi gabungannya selama periode penelitian.

This study analyses whether the usage of interrelated informations in revenue surprise, earnings surprise, and prior returns adds value to the implementation of investment strategy in Indonesia Stock Exchange for 2001-2012 period. This study also indirectly examines the existence of price momentum and postearnings- announcement drift anomalies. This study finds that there is a tendency of investors to underreact to fundamental performance information, but on the other hand overreact to previous 6 months market performance information. It is explained by the effectiveness revenue and earnings momentum strategies, and the ineffectiveness of price momentum strategy. The test of strategy domination shows that each strategies has an independent profit contribution to each other, and these profits persist even after being adjusted to the CAPM and Fama-French 3 factors model. It is proven in this study that the implementation of multivariate strategies gives significant positive incremental returns. This indicates that each informations has an exclusive content that is unpriced by the market and investors tend to underestimate the combined implication of those informations during the research period."
