A Multicriteria Extension of the Efficient Market Hypothesis
Mathematics, 2021 Challenging the Efficient Market Hypothesis (EMH) has been a recurrent topic for researchers and practitioners since its formulation. Hundreds of empirical studies claim to either prove or disprove the EMH by means of a number of heterogeneous methods ...

Atoms with bosonic "electrons" in strong magnetic fields
, 2000 We study the ground state properties of an atom with nuclear charge $Z$ and $N$ bosonic ``electrons'' in the presence of a homogeneous magnetic field $B$.

Intraday anomalies and market efficiency : a trading robot analysis [PDF]
, 2014 One of the leading criticisms of the Efficient Market Hypothesis (EMH) is the presence of so-called "anomalies", i.e. empirical evidence of abnormal behaviour of asset prices which is inconsistent with market efficiency. However, most studies do not take

Toward a Theory of Marginally Efficient Markets
, 1999 Empirical evidence suggests that even the most competitive markets are not strictly efficient. Price histories can be used to predict near future returns with a probability better than random chance. Many markets can be considered as {\it favorable games}

Materials and Corrosion, EarlyView.Ta‐Mo‐Cr‐Ti‐Al refractory high‐entropy alloys show atmosphere‐dependent oxidation performance based on Cr:Ti ratios. Cr‐rich compositions excel in dry oxygen through continuous chromia formation, while Ti‐rich alloys perform better in humid conditions due to reduced chromium volatilization and hydrogen uptake effects.

Oikos, EarlyView.Plants live in a heterogeneous world, where nutrient and neighbour distributions vary in space and time. Plants can respond to this variation through plastic responses in individual organs, which are assumed to be coordinated among traits to support a coherent, adaptive strategy, maintaining plant growth in varying environments.

Market efficiency and the Euro: the case of the Athens Stock Exchange [PDF]
, 2003 The efficient market hypothesis (EMH) is tested in the case of the Athens Stock Exchange (ASE) after the introduction of the euro. The underlying assumption is that stock prices would be more transparent; their performance easier to compare; the ...

Asia‐Pacific Economic History Review, Volume 65, Issue 1, Page 131-159, March 2025.Abstract This study examines the adaptive market hypothesis in the prewar and wartime Japanese stock market using a new market capitalization‐weighted price index. First, we find that the degree of market efficiency varies over time and with major historical events. This implies that the hypothesis is supported in this market.
