摘要

从投资者的角度来看,股息被认为是最重要的管理决策之一,然而在公司融资领域,股息仍然是一个有争议的问题[1]。尽管已有关于股息与股市关系的文献,但很少有人关注媒体事件及其对印度股市结果的影响。本文运用神经网络理论考察新闻、股利支付及其决定因素之间的定量关系。进一步研究的重点是了解不同部门和行业是否与事件后股市结果相关。使用2001年至2015年期间在印度国家证券交易所有限公司上市的1362家公司的样本,我们发现净销售额,税后利润,现金余额,总储备,上一年股息,资产净额和外汇收入收益和费用的变量在确定九个部门的支付决策方面具有重要意义。随机森林回归的结果得分高于研究中使用的其他神经模型。最后,通货膨胀、黄金价格、美国联邦利率、欧洲央行利率和美元汇率对派息决定和最终派息的决定因素有重大影响。

Linkages between news and dividend decisions using neural networks
Dividends are considered to be one of the most important management decisions from the point of views of investors, however in the area of corporate finance it still remains a controversial issue [1]. Despite the existent literature on dividends and stock market relationships, little focus is found on media events and its impact on Indian stock market outcomes. This article uses neural network theory to examine the quantitative relation between news, dividend payouts and its determinants. Further the research focuses on understanding whether different sectors and industries relate to stock market outcomes post event impact. Using a sample of 1362 companies listed on the National Stock Exchange of India Ltd between the periods of 2001–2015, we find that variables of net sales, profit after tax, cash balances, total reserves, previous year dividends, net block of assets and forex revenue earnings and expenses are significant in determining the payout decision across the nine sectors examined. The results from random forest regression score above the other neural models used in the study. Lastly, inflation, gold prices, US federal interest rates, ECB interest rates and dollar exchange rates carry significant influence on the determinants of dividend payout decision and eventually the payout.
