Mercado de capitales

Nicolás Guillermo Cámpoli, 2018

El mercado de capitales es un mercado financiero en el cual se compran y venden títulos, principalmente de acciones, que representan los activos financieros de las empresas que cotizan en bolsa. El objetivo de este trabajo es orientar e informar al inversor sobre el mercado de capitales brindado algunos datos de interés, para luego mediante la teoría de portafolio construir una cartera de valores eficiente que pueda ser comparada con el mercado, el cual viene representado por el índice Merval.

Análisis de la ley 26.831, sus principales novedades y comparación con el régimen derogado

Cada vez que realicemos una inversión esta demanda capital. Una empresa necesita atraer inversionistas que adquieran acciones de la compañía, que son las empresas que cotizan en bolsa de valores, ofreciéndoles cierto monto de rentabilidad, lo que genera un costo para la compañía llamado el "costo de capital", cierta rentabilidad se ve ofrecida a los accionistas por medio de dividendos, que es un cierto porcentaje de las utilidades repartido entre los accionistas, siendo una especie de ahorro e inversión entre los inversionistas y accionistas de la compañía . Esta compra y venta de títulos accionarios se conoce como mercado de capitales. (Millán & Montilla, 2014) DESARROLLO En los estudios financieros conseguir una mezcla adecuada de rentabilidad respecto al nivel de riesgo, es uno de los problemas más grandes que se presentan. Se ha logrado establecer que cuando se cuenta con un histórico del comportamiento, y realizar un análisis de este es posible llegar a una aproximación haciendo pronósticos futuros, esto con el fin de tomar las mejores decisiones. En la administración de portafolios de inversión, aplicar herramientas cuantitativas es aún más confiable ya que existen grandes bases de datos históricos que nos

We study the holographic entanglement entropy for singular surfaces in theories described holographically by hyperscaling violating backgrounds. We consider singular surfaces consisting of cones or creases in diverse dimensions. The structure of UV divergences of entanglement entropy exhibits new logarithmic terms whose coefficients, being cut-off independent, could be used to define new central charges in the nearly smooth limit. We also show that there is a relation between these central charges and the one appearing in the two-point function of the energy-momentum tensor. Finally we examine how this relation is affected by considering higher-curvature terms in the gravitational action.

Two experiments were designed to estimate the effect of methionine levels (0.33 and 0.45%) with betaine and folic acid on broiler performance. A total of 648 unsexed one week old Arbor Acres broiler chicks was randomly divided into two experiments according to dietary methionine level. Each experiment divided into nine treatment groups of 12 birds each with three replicates. The experimental diets were formulated to cover the nutrients requirements for broilers and were supplemented with betaine at 0.5, 0.75 or 1.0 gm kgG . Folic acid was added at 0.5, 0.75 or 1.0 mg kgG for each betaine level. Results can be summarized as 1 1 follows: Live body weight gain and feed conversion efficiency were significantly increased with increasing folic acid addition and increased with increasing betaine levels up to 0.75 gm kgG diet. Productive 1 performance was significantly improved by increasing different levels of betaine and folic acid. The OM, CP, EE, CF and NFE digestion coefficients were significantly (p>0.5) increased with increasing betaine or folic acid levels in the diets. The improvement of chick performance due to added betaine was depressed when chicks received diets containing recommended methionine, whereas, chicks performance improved by increasing folic acid level. Folic acid had significant effect on dressing %, the highest level received the highest dressing % recorded, while no significant effects were noticed in digestion coefficients of nutrients. Blood plasma AST and ALT decreased with increasing dietary methionine level. The highest economic efficiency was listed when diet contained the highest levels of betaine and folic acid.
