Resumen
Durante los últimos años, la Bolsa de Valores de Lima (BVL) ha sido cuestionada
por los bajos niveles de liquidez que presenta; en consecuencia, proveedores de
índices bursátiles como MSCI o FTSE han puesto en revisión la categoría de
mercado que sostiene la cual podría pasar de ser considerado mercado
emergente a mercado frontera. Es por ello que, resulta importante medir dichos
niveles de iliquidez y los efectos que estos pueden tener en las acciones que
transan en la bolsa local. El presente documento muestra la relación positiva
entre los excesos de los retornos esperados de los activos y la iliquidez de la
Bolsa de Valores de Lima (BVL). Se emplea un modelo de valorización de activos
ajustado por liquidez bajo el cual el retorno de un activo depende de su liquidez
esperada así como de las covarianzas de su propio retorno y su propia liquidez
con el retorno de mercado y la liquidez de mercado. Adicionalmente, las
aplicaciones empíricas emplean un modelo de dos regímenes Markov Chain con
el objetivo de estimar escenarios de alta y baja iliquidez para los betas de los
activos. Los resultados muestran la importancia de considerar la iliquidez cuando
se construyen y evalúan portafolios de acciones en la BVL.
Over the last few years, the Lima Stock Exchange (BVL) has been questioned due to the low levels of liquidity it presents; consequently, providers of stock indices such as MSCI or FTSE have put under review the market category that maintains the quality could go from being considered an emerging market to a frontier market. For this reason, it is important to measure these levels of illiquidity and the effects that these may have on the actions traded on the local stock market. This document shows the positive relationship between the excesses of the expected returns on assets and the illiquidity of the Lima Stock Exchange (BVL). A liquidity-adjusted asset valuation model is used under which the return of an asset depends on its expected liquidity as well as the covariances of its own return and its own liquidity with market return and market liquidity. Additionally, the empirical applications employ a two Markov Chain regimes model with the objective of estimating high and low illiquidity scenarios for the asset betas. The results show the importance of considering illiquidity when building and evaluating stock portfolios in the BVL.
