Full textThis proposed thesis uses the Haar wavelets to create new technical indicators, to evaluate their performance in order to test the validity of the weak form of efficient market hypothesis. The chosen approach aims to implement the capabilities of technical indicators to capture the long memory present in the US and European stock indices through the estimation of the trend by the smoothing process. Moreover, the trend is an important component in the economic and financial series. Indeed, it has been the subject of innumerable investigations in technical analysis, in signal processing and in the theory business cycle theory. However, its presence is not taken into account in the classic theory of finance because the main models used focus on changes in stock prices. For this purpose, the trend constitutes a source of non-stationarity leading to major difficulties for econometric or financial modeling. Exploit trend is freed, in this case, from the hypotheses of tendancy or unit root. In addition, the issue of the results we obtained from the regime change model. We confirm that it is possible to exploit the presence of long memory in the series, and also to beat the market in the presence of transaction costs on the American and European markets

Full textThe aim of my thesis was to find criteria on families of Calderon-Zygmund operators to know if, with iterated commutators, they characterize product BMO space. Multiparameter BMO space is a generalization of classical BMO space, and began to be studied during the eighties by Chang and Fefferman. To each parameter is associated a Calderon-Zygmund operator acting on this parameter. We define also, associated to b in BMO, the operator Mb of multiplication by b. Then we define iterated commutators with those Calderon-Zygmund operators and the operator Mb. Then the aim is to study the relation between the BMO norm of b and the norm of the commutator acting on L2. The first result in one parameter case is due to Coifman, Rochberg and Weiss, who proved that Riesz transforms characterize BMO. The next result is due to Uchiyama, who gave a criterion on families of Calderon-Zygmund operators to show if they generalize Stein-Fefferman decomposition. Then Li gave another criterion on those families of Calderon-Zygmund operators, to show if commutators characterize BMO. The first result in multiparameter case is due to Ferguson-Lacey, who proved in the case of parameter t=2 that Hilbert transform characterize BMO. Then Lacey and Terwilleger extended this result to arbitraly number of iterations. Finally, Lacey-Petermichl-Wick-Pipher extended this result to Riesz transform in product BMO space. So, first, I found a criterion on families of Calderon-Zygmund operators to know if they characterize product BMO space. Finally, I proved that commutators norms are majorized, up to a multiplicative constant, by BMO norm of b in multiparameter case for any kind of Calderon-Zygmund commutators, using the representation theorem of Hytonen, which reduces the problem to dyadic shifts
