Abstract

El presente trabajo tiene por objetivo determinar el impacto financiero de los comunicados y las decisiones del Federal Open Market Committee (FOMC) sobre los rendimientos accionarios de 56 emisoras del sector industrial del S&P 500; dicho índice es relevante dada su capacidad de representar el mercado bursátil estadounidense. La hipótesis fue contrastada mediante la metodología de estudio de eventos, tomando como fechas de eventos los anuncios de política monetaria de la FED sobre variaciones de la tasa de fondos federales durante el periodo comprendido entre enero del 2021 y abril del 2023. Los resultados permiten rechazar la hipótesis nula: los anuncios del Comité Federal del Mercado Abierto (FOMC) relativos a la tasa de interés no presentan un impacto cuantificable en el desempeño bursátil de las empresas analizadas. Los hallazgos permiten constatar que los anuncios de política monetaria de la FED afectan los retornos de las emisoras del sector industrial del S&P 500, de manera compatible con la forma semifuerte de la teoría de los mercados eficientes; no obstante, la dirección del efecto está altamente vinculada al régimen macrofinanciero vigente. En términos agregados, los hallazgos muestran que el ritmo de la política monetaria y su comunicación son relevantes en las cotizaciones de las empresas industriales del S&P 500. El estudio proporciona evidencia empírica útil para la gestión de portafolios, la valuación de empresas y gestión de riesgos a escala sectorial. The objective of this study is to determine the financial impact of the statements and decisions of the Federal Open Market Committee (FOMC) on the stock returns of 56 issuers in the industrial sector of the S&P 500, an index relevant for its ability to represent the U.S. stock market. The hypothesis was tested using event study methodology, considering as event dates the Federal Reserve's monetary policy announcements regarding changes in the federal funds rate during the period from January 2021 to April 2023. The results allow for the rejection of the null hypothesis: FOMC announcements regarding interest rates do have a measurable impact on the stock market performance of the firms analyzed. The findings confirm that the Federal Reserve's monetary policy announcements affect the returns of industrial sector firms in the S&P 500, in a manner consistent with the semi-strong form of the efficient market hypothesis; however, the direction of the effect is closely linked to the prevailing macro-financial regime. In aggregate terms, the findings show that both the pace of monetary policy and its communication are relevant to the stock prices of S&P 500 industrial firms. The study provides useful empirical evidence for portfolio management, firm valuation, and risk management at the sectoral level.
