摘要

摘要近年来,人工神经网络已成功应用于预测金融时间序列、预测金融失败和评级分类等领域。然而,它几乎没有被应用于预测伊斯兰债券价格,而这被认为是最常见的伊斯兰资本市场工具。由于伊斯兰债券是一种新的金融资产,因此在这方面的研究还不够。因此,本研究旨在利用人工神经网络模型对土耳其主权伊斯兰债券价格进行预测,并揭示影响伊斯兰债券价格预测的因素。为此,利用土耳其财政部发布的以美元为基础的国际主权伊斯兰债券价格数据,设计了多层前馈人工神经网络模型。美元指数、波动率指数、地缘政治风险指数、标准普尔中东和北非伊斯兰债券指数、欧洲债券价格构成所设计模型的输入变量,主权伊斯兰债券价格构成输出变量。结果,主权债券价格的预测准确率达到了99.98%。对伊斯兰债券价格的准确预测,对于降低伊斯兰债券投资者的风险认知,提高其盈利能力具有至关重要的作用。研究结果证明了人工神经网络模型是预测伊斯兰债券价格的有效模型,并揭示了美元指数、波动率指数、地缘政治风险指数、标准普尔中东和北非伊斯兰债券指数和欧洲债券价格是预测伊斯兰债券价格的决定因素。

Forecasting of Turkish Sovereign Sukuk Prices Using Artificial Neural Network Model
This work is licensed under Creative Commons Attribution-NonCommercial 4.0 International License ABSTRACT Recently, artificial neural networks have been successfully applied in many areas such as forecasting financial time series, predicting financial failure, and classification of ratings. However, it has hardly been applied in forecasting sukuk prices, which is considered the most common Islamic capital market instrument. Since sukuk is a new financial asset, there are not enough studies in this area. Therefore, this study aims to forecast the Turkish sovereign sukuk prices using with artificial neural network model and to reveal the determinants in the forecasting of sukuk prices. For this purpose, a multi-layer feed forward artificial neural network model is designed using dollar-based international sovereign sukuk price data issued by the Turkish Ministry of Treasury and Finance. The dollar index, volatility index, geopolitical risk index, Standard and Poor’s Middle East and North Africa sukuk index, and Eurobond prices constituted as input variables of the designed model and the sovereign sukuk prices formed the output. As a result, the sovereign sukuk prices were forecasted accurately at the success rate of 99.98%. The accurate forecasting of sukuk prices will play a critical role in reducing the risk perception of sukuk investors and increasing their profitability. The findings of the study are important in terms of proving that the artificial neural network model is an effective model for forecasting the sukuk prices and revealing that the dollar index, volatility index, geopolitical risk index, Standard and Poor’s MENA sukuk index, and Eurobond prices are determinants in forecasting sukuk prices.
