Abstract

[spa] La autonomia del mercado bursatil francés : ¿ Los mercados francés y norteamericano están integrados ? - Las variables propias a la economía francesa (resultados de las empresas, tasas de interés, etc.) no son siempre suficientes para explicar por completo los movimientos del mercado bursatil nacional. Dichos movimientos, por el contrario, se encuentran en correlación con las variaciones del mercado norteamericano. A pesar de ello, no se puede llegar a la conclusión de que existe una integración de ambos mercados. Wall Street solo es susceptible de amplificar, reducir, hacer retroceder las tendencias del mercado parisiense, pero no de determinarlas. . Un enfoque econométrico que surge de una reflexion teórica acerca de la noción de integración permite extraer como consecuencia la no integración de los dos mercados. Este resultado no es paradójico, en primer lugar porque los mercados no son totalmente independientes uno de otro y algunos acontecimientos macroeconómicos de orden internacional pueden ejercer ciertos efectos sobre ellos. En segundo lugar, porque los que intervienen en el mercado francés están atentos a las evoluciones de Wall Street sin estar ligados al mercado norteamericano. [fre] Les variables propres à l'économie française (performances des entreprises, taux d'intérêt, etc.) ne suffisent pas à expliquer complètement les mouvements du marché boursier national. Ces derniers, en revanche, sont bien corrélés avec les variations du marché américain. Pour autant, on ne saurait en toute rigueur conclure à l'intégration des deux marchés. Wall Street n'est susceptible que d'amplifier, réduire, retarder... les tendances du marché parisien, non de les déterminer. . Une approche économétrique, issue d'une réflexion théorique sur la notion d'intégration, permet de conclure à la non-intégration des marchés français et américain. Ce résultat n'est pas paradoxal, d'abord parce que les marchés ne sont pas pour autant totalement indépendants l'un de l'autre et que des événements macro-économiques d'ordre international peuvent agir communément sur les deux marchés, ensuite parce que les intervenants sur le marché français sont attentifs aux évolutions de Wall Street, même s'ils ne sont pas engagés sur le marché américain. [eng] The Autonomy of the French Stock Market. Are the French and the American Markets Well-integrated ? - The variables which relate to the French economy (firm results, interest rates, etc.) cannot always entirely explain the movements of the national stock market. These movements, on the other hand, are well-corellated with fluctuations on the American market. One cannot, however, draw the absolute conclusion that the two markets are integrated. Wall Street may amplify, reduce or delay the trends of the Paris market, but it is not likely to determine them. An econometric approach, derived from theoretical reasoning about the concept of integration, makes it possible to conclude that the French and American markets are not integrated. This result is not paradoxical, first, because the market are not totally independent from each other and macroeconomic global international events can act simultaneously on both markets, and further because participants in the French markets closely watch trends on Wall Street, even if they are not directly involved in the American market.
