Resumen:Se estima el efecto de la implementación de la plataforma transaccional X-Stream en la calidad de mercado accionario colombiano en Febrero de 2009. En particular se estudia el efecto en medidas de liquidez, (margen oferta-demanda e impacto en el precio), volatilidad diaria e intradiaria, y actividad bursátil, empleando modelos econométricos de prueba de medias, panel datos y varianza condicional. Para este fin se usa una base de datos de órdenes y transacciones provistas por BVC. La evidencia muestra que X-Stream mejoró la calidad del mercado accionario colombiano, otorgándole mayor liquidez, y menor volatilidad al mercado en general y a la mayoría de acciones de alta liquidez. Esta evidencia se constituye en un argumento a favor de las inversiones en modernización de los sistemas transaccionales en los mercados emergentes.Abstract:We estimate the effect of the new trading system, X-Stream, on the market quality of the Colombian Stock Exchange on February 2009. We test the effect on liquidity measures (bid-ask margin and price impact), daily and intraday volatility and trading activity, using mean tests, panel data and conditional variance models. We use a proprietary database of transactional and order data from the exchange. The evidence is consistent with X-Stream improving liquidity and reducing volatility in the overall market and on most of the most liquid stocks. These results support the investment on more sophisticated trading systems in Emerging Markets.
