摘要

本研究考察了分析师在2019冠状病毒病之前和期间对美国(发达国家)和马来西亚(符合伊斯兰教法的新兴股票)市场流动性和信息效率的预测的影响。结果表明,分析师的预测在疫情前对市场流动性有显著影响,但在疫情期间影响减弱。此外,分析师的预测对美国市场的高分位数(0.7和0.9分位数)和马来西亚伊斯兰市场的低分位数(0.1和0.3分位数)的影响是显著的。同样,在新冠肺炎之前,美国市场的买入卖出建议和预测的所有变量都具有重要意义。在新冠疫情期间,这两个市场都变得低效,分析师的预测不再与信息效率相关。这些结果为从业者和投资者在COVID-19等扰乱国际金融市场的市场压力下检查市场状况和投资者行为提供了依据。

INFORMATION EFFICIENCY IN THE U.S. AND SHARIAH-COMPLAINT STOCKS IN MALAYSIA DURING COVID-19
This study examines the impact of analysts’ forecast of market liquidity and information efficiency in the U.S (developed) and Malaysia (emerging – Shariah-compliant stocks) before and during COVID-19.  The results show that the analysts’ forecast is significant to the market liquidity in the pre-COVID period but its influence diminishes during the COVID-19. Moreover, the impact of the analysts’ forecast is significant in the upper quantiles (0.7 and 0.9 quantiles) of the U.S market and in the lower quantiles (0.1 and 0.3 quantiles) of Malaysia's Islamic market. Similarly, the buy-sell recommendations in the U.S market and all variables forecasted are significant before COVID-19. Both markets become inefficient during COVID-19, and analysts’ forecast is no longer correlated to information efficiency. These results inform practitioners and investors to inspect the market conditions and investor's behavior under market stress such as COVID-19, which has disrupted the international financial markets.
