The sharp peak-flat trough pattern and critical speculation

The sharp peak-flat trough pattern and critical speculation

We find empirically a characteristic sharp peak-flat trough pattern in a large set of commodity prices. We argue that the sharp peak structure reflects an endogenous inter-market organization, and that peaks may be seen as local “singularities” resulting from imitation and herding. These findings impose a novel stringent constraint on the construction of models. PACS numbers : 01.75+m Science a...

Peak and Trough.

Dow Theory’s Peak-and-Trough Analysis Justified

In the analysis of dynamic financial quantities such as stock prices, equity prices, etc., reasonable results are often obtained if we only consider local maxima (“peaks”) and local minima (“troughs”) and ignore all the other values. The empirical success of this strategy remains a mystery. In this paper, we provide a possible explanation for this success. 1 Formulation of the Problem Peak-and-...

Critical population and error threshold on the sharp peak landscape for the Wright-Fisher model

We pursue the task of developing a finite population counterpart to Eigen’s model. We consider the classical Wright–Fisher model describing the evolution of a population of size m of chromosomes of length l over an alphabet of cardinality κ. The mutation probability per locus is q. The replication rate is σ > 1 for the master sequence and 1 for the other sequences. We study the equilibrium dist...

the relationship between critical thinking and reading strategies

during the process of reading, sometimes learners use ineffective and inefficient strategies and some factors may influence their use of strategies. perhaps critical thinking is one of these factors. this study aims to identify those categories of reading strategies that are mostly used by iranian efl learners and to see if there is any significant relationship between the critical thinking abi...
