Financial economists usually assess market efficiency in absolute terms. This is to be viewed as a shortcoming. One way of dealing with the relative efficiency of markets is to resort to the efficiency interpretation provided by algorithmic complexity theory. We employ such an approach in order...

The purpose of this article is to investigate whether, how and when, from a statistical standpoint, Technical Analysis strategies tools hold true for the futures contract of Ibovespa Index, negotiated at the Brazilian Futures Exchange (“Bolsa Brasileira de Mercadorias e Futuros – BM&F”),...

In this study, we examine unsuccessful takeover attempts for new evidence on whether mergers create or destroy value for acquirers and targets. We contribute to the literature in three important areas. First, we contribute to the literature on signaling by investigating whether a takeover...

In this paper, we investigate the effect of institutional investors on the January stock market anomaly. The Polish and Hungarian pension system reforms and the associated increase in investment activities of pension funds are used as a unique institutional characteristic to provide evidence on...

We show by explicit closed form calculations that a Hurst exponent H≠1/2 does not necessarily imply long time correlations like those found in fractional Brownian motion. We construct a large set of scaling solutions of Fokker-Planck partial differential equations where H≠1/2. Thus Markov...

This study is undertaken to investigate the extent to which mergers lead to efficiency by which services are provided to the public and the productivity of Malaysia’s banking institutions sector. The data cover the period 1993 to 2004, which includes the pre-merger years and the post-merger...

In this paper we propose a new test for efficiency of spot and forward markets where returns are nonstationary and cointegrated. The test for market efficiency is developed within the framework of a vector error correction (VEC) representation of a bivariate vector autoregression (VAR) model....

We find that turnover rises on n-day highs and lows and is an increasing function of n. We offer several explanations from the technical and behavioral finance literature for why traders might use these signals. Turnover is persistent following these events, and new lows provide abnormal returns...

The Nasdaq stock market provides information about buying and selling interest in what is called the Level II display. Using a bivariate VAR model of trades and quotes, I assess the effect of Level II prices and depths on short-run quote dynamics. I also determine the influence of individual...

This paper documents the significant role of ECNs in forming the inside market in NASDAQ securities. We argue that the ECNs need to be exposed to market orders through the SOES system.
