摘要

在进行投资决策之前,投资者必须借助投资策略来了解投资的风险收益特征。这些投资策略,包括撤资、战术资产配置和卖空,被投资者和基金经理用来通过最大化回报和最小化风险来提高投资组合的表现。本研究旨在检验战术资产配置对尼日利亚股票市场风险收益关系的调节作用。研究样本是90只股票,这些股票在尼日利亚股票市场上持续交易了16年,每月一次。本研究采用的时间序列数据摘自NGX网站、年度财务报表和CBN统计公报。本研究的数据收集和分析框架基于Fama和French(2015)的方法,使用FamaMacbeth的两步回归。该研究使用价格的对数现值与前一个价格之间的差值来计算回报。结果表明,在尼日利亚股市的CoFF5F和HMFF5F下,战术资产配置没有显著定价。此外,引入战术资产配置作为调节变量并不能改善尼日利亚股市风险与收益之间的关系。鉴于此,本研究得出结论,战术资产配置不能通过尼日利亚股票市场的风险最小化和收益最大化来改善风险与收益的关系。本研究建议投资者可以采用其他投资策略,如回调、卖空等,来改善尼日利亚股市的风险与收益关系。

Moderating Effect of Tactical Asset Allocation on the Risk-Return Relationship in the Nigerian Stock Market
Before making investment decisions, the investor must find out the risk-return characteristics of investments with the help of investment strategies. These investment strategies, including drawdown, tactical asset allocation and short selling, are used by investors and fund managers to improve portfolio performance by maximizing returns and minimizing risks. This study aims to examine the moderating effect of tactical asset allocation on the risk-return relationship in the Nigerian stock market. The study sample is 90 stocks that are consistently traded in the Nigerian stock market within the period of sixteen years on a monthly basis. The study employed time series data which were extracted from the NGX website, annual financial statement, and CBN statistical bulletin. This study's data collection and analysis framework was based on the methodology of Fama and French (2015) using FamaMacbeth's two-step regression. The study used the difference between the logarithmic present value of the price and the previous value of the price to compute the return. Evidence from the result revealed that tactical asset allocation is not significantly priced under the CoFF5F and HMFF5F in the Nigerian stock market. Also, introducing tactical asset allocation as the moderating variable does not improve the relationship between risk and return in the Nigerian stock market. In light of this, the study concluded that tactical asset allocation could not be used to improve the relationship between risk and return through the minimization of risk and maximization of return in the Nigerian stock market. The study recommends that other investment strategies, such as drawdown, short selling etc., can be used by investors to improve the relationship between risk and return in the Nigerian stock market.
